This was primarily written for 9N/2N/8N tractors that I use (a Ford 3000 was recently added to the fleet).
Most of this web site is about tractor repairs, restoration, and maintenance. I do enjoy working on my tractors, but all this would be pretty pointless, if I didn't enjoy using them. Some tractors get fixed up so pretty, they only come out for shows and parades. Not mine. One did make it to a show, once, but mostly my tractors stay dirty. Working tractors need IMPLEMENTS. "Implements" is just a fancy word for tools. Any excuse to buy more tools is a very good thing, and the root cause of my tractor addiction is finally revealed. All of my implements are used, and some have been abused. Used implements usually have plenty of life in them. When buying a tractor, always ask "What comes with it?". No telling what might be offered as part of the sale.
Do not be too embarrassed to ask questions and get a free lesson in tractor operation from the salesman or previous owner. They want to make the sale, and they should be obliged to make sure you know how to operate the tractor. Walk around the tractor and ask about anything you don't understand. There may be lots of little knobs and levers in places you will never see just sitting on the seat. Most sellers will be eager to explain everything. Expect to see more than one transmission shift lever, more than one brake pedal, four or more controls for the 3-point lift and PTO shaft. Throttle controls are usually hand-operated. Some tractors will have both hand and foot throttle controls. If there is a front loader, there will be separate controls for that. Tractors are very different from any car.
Do not hook up an implement until you have driven the tractor enough to get comfortable with the basic operating controls. It's ok if there is already something hanging on the tractor when you pick it up. Just let it hang back there while you figure out the basic tractor controls. Try to find out if the rear tires are filled, how good the brakes work, steering, clutch, and test the speed in various forward and reverse gears. Hey, this is the fun part, take the time to drive the tractor, and build confidence before plowing thru the rose bushes with a cutter.
Try steering with the brakes. Tractors usually have separate pedals for right and left brakes. This takes some getting used to. On newer tractors there may be a way to lock the two brake pedals together. Separate right and left brake pedals allow the tractor to be steered with the brakes. That's a good thing when a heavy load has the front tires only touching the ground occasionally. Now is the time to find out if one brake works better than the other (or if the brakes work at all). Even with good brakes, don't expect a tractor to stop anything like your car does.
Very few tractors are designed to shift on-the-fly. In most cases you select what gear you want to use, then ease the clutch out to start the tractor moving. In higher (faster) gears this can seem like a lot of time "riding" the clutch. With most tractors second gear seems to be the main "working" gear for most implements. Start there, then try other available gears to see what works best for the job you are doing. All of my tractors have different sets of main gear ratios, and different auxiliary (overdrive and underdrive) transmissions. My 2N has an overdrive that provides a total of six forward gears/two reverse. My 8N has a Sherman combo that provides a total of 12 forward gears/three reverse. The 3000 has a dual-range 4 speed with 8 forward gears/two reverse.
Practice backing-up and lining-up with something that won't be killed if it gets run over. You do not want to discover a sticky clutch or bad brakes by running into (or completely over) the dog or something expensive. Learn how to back-up square and centered on an implement. Many implements are too heavy to be moved much by hand. Attempting to manually adjust the position of heavy implements has caused many injuries.
Hooking implements to the 3-point lift can be difficult, especially if you just drop implements anywhere. Implements are much easier to attach if they are parked on level ground, with blocks to keep them from getting buried in dirt and weeds. It's a lot easier to hook up if the rear tractor tires are sitting on the same slope as the implement. Try to leave parked implements next to a fairly level stretch of driveway, or at the edge of a field.
Back up to the implement. Make sure the PTO shaft is not turning! Set the parking brakes. Connect the non-movable lower lift arm first. That is usually the left arm. Look for a thingy on one side (usually the right) with a crank handle. That is the leveling box. Turning the crank will raise or lower the lift arm it is attached to. The other lift arm is the non-movable one that you want to hook up first. Hopefully, if you backed the tractor perfectly, all you have to do is crank the leveling box a turn or two, to align the second arm. If not, try hooking up the top link, and crank that in or out to get the second lower link to line up. A long pry bar may be enough to shift some implements.
Note the second leveling box. This is a standard leveling box, modified to fit on the left side. This provides twice as much adjustment, and either arm can be hooked up first. This is a very handy modification that I make to all of my tractors.
Always use the correct size and type of lynch pins. Most are 7/16 x 1-3/4" usable length, inside the loop. Buy a supply of these and keep a few in the tool box on each tractor. You may think you only need 6, but they are always getting lost. Tie wire can be added to help keep brush from flipping them loose. Some suppliers sell assortments of various pins and clips. Having an assortment of sizes and types handy is much better than using bolts, wire, string, and other rotten things I've had to remove.
Get a set of stabilizer arms (bars). Stabilizer bars keep the implement from swinging freely from side to side. Most tractors just have short chains that stop the swing just before the lower arms hit the tires. This allows a lot of swing from side to side. There is no need to go around leaving deep gouges in the wife's car, knocking corners off the house, or ripping the new gate off its hinges. In addition to keeping the implement centered. The stabilizer bars make a triangle with each lower lift arm which greatly helps to stiffen the system when pushing in reverse. The lift system and lower arms were designed for pulling, not pushing. Stabilizer bars should be used with every implement, except the plow. Make sure the front pivot point for the bars is directly across from the front pivot for the lower lift arm, or they will bind when the lift goes up and down. Some implements such as a bottom plow should be allowed to run free.
No, "stay bars" isn't just an abbreviation for stabilizer bars discussed above. Stay bars are a set of adjustable bars that go from the top link to the lower lift arms. Stay bars are used to lock the lower lift arms down low when using a draw bar to tow or drag. The lift is gravity down, with no down pressure. Without stay bars the arms will rise up when pulling. This is very unsafe. Never pull anything with the lift arms raised. Never hook anything above the centerline of the rear axle. Stay bars usually come with a chain and tag to lock the touch control lever in the down position. This is just a reminder not to try and raise the lift when the stays are attached. Stays and Stabilizer bars can be used at the same time with a drawbar.
There are at least three different category 1 top link body lengths, and unless you only use one implement, you will eventually need all of them. Some people buy a top link for each implement, so they can leave them set to a specific length. That's a little extreme for me. I have one of each length, plus one of the original sliding-type adjustable top links.
The N-Series tractors were all built well before there was any standard for 3-point lifts. Manufacturers did not agree on a standard until the 60's. Refer to the table below. The N-Tractor lift matches up best with Category 1. We should be able to use most Category 1 and 2 implements. The problem I've run into is that "standard" Category 1 and 2 implements are not very standard. Some are almost too wide for the lower arms, or the top link is at an odd location.
THREE POINT LIFT STANDARDS
|Category||Tractor HP||Top Link Pin Diameter||Lift Arm Pin Diameter|
|0||Up to 20||5/8 in||5/8 in|
|1||20 to 45||3/4 in||7/8 in|
|2||40 to 100||1 in||1-1/8 in|
|3||80 to 225||1-1/4 in||1-7/16 in|
|4||180 and up||1-3/4 in||2 in|
|These are the basic specifications. The full standards include additional specifications on dimensions and geometry.|
I bought one of these and ended up giving it away. Seems like a great idea! Just back up to any implement, click, click, and drive away! What I discovered is that many of my implements would not attach to the Quick Hitch. Removing the Quick Hitch to use those implements just added more work and busted knuckles. The only way any of the Quick Hitch devices will work as advertised, is if all your implements will easily attach to it. Measure your implements. How far apart are the lower link pins? Are all the top link connections the same height from the lower links? Anything that reduces how many times we have to leave the seat when hooking up is a great safety feature. Maybe one of these will work for you. Great if it does. If not, don't say I didn't warn you.
The Top Link Rocker is where the top link connects to the tractor. ALWAYS use a top link with all implements. Most N-Tractors will only have one place on the rocker to connect the top link to the tractor (no confusion with those). Near the end of 1949, the top link rocker was changed from the single hole to a 3-hole design. The new rocker provides two additional connection points that are higher than the original connection. Always use the lowest position for plowing. Use the higher mounting points only when a light ground-engaging implement does not provide enough feedback to the draft control mechanism. This should only be the case with something like a cultivator in loose soil. Be careful! If the implement should hit an obstruction, the higher mounting points allow a LOT more force on the spring and lift control mechanism. You are much more likely to break something.
My most-used implements are back blades. The main reason I started looking for a tractor was driveway maintenance and snow removal. Maintaining the driveway is still the primary work for my tractors. Both of my back blades are 5-feet wide and have seen many years of hard use before I got them. One of my blades has many more options for how it can be used.
Don't automatically decide to buy a load of gravel without first working the driveway. In most cases there will already be plenty of gravel near the surface. Gravel doesn't evaporate, or wear out. The ideal gravel driveway surface is a mixture of gravel and dirt that will quickly pack down into a tight, stable driving surface. Loose dirt and smaller stones will settle down into the gravel as it is packed, and help lock the larger stones in place. Done right, this surface can become nearly as hard and stable as pavement.
Some people do a lot of blade work in reverse gear. The main part of our driveway is over 750 feet long. I can't imagine what my neck would feel like if I tried to do much of that in reverse. Running in forward gears is much faster, and with a blade no wider than the tires, there is little need to watch what the blade is doing.
If the driveway is in good shape, don't get carried away digging up the packed gravel base. If all it needs is a quick touch-up, see if your blade can be rotated all the way around backwards. This will turn the edge so it cannot dig-in. Set the blade angled just one position from straight across. Run fairly fast, in second gear, with the forward end of the blade at the edge of the drive, so the blade pulls a little loose gravel from the edge to the middle.
If the driveway is heavily rutted, the blade needs to dig-in and move a lot of material. The best time to do this is right after a good rain. The water helps loosen the driveway, but mostly because a damp driveway will make much less dust. Set the blade angled just one position from straight across. Use a long top link, so the leading edge of the blade can really dig-in, and pick-up material. Cranking the leveling box so the leading tip end of the blade is slightly lower will also help. The intent is to dig-up material from the edge, and move it slightly towards the center of the driveway. Run in first gear with the leading tip of the blade at the edge of the driveway. It might take 2 or 3 passes to loosen enough material to completely fill deep ruts. Adding weight to the blade may be necessary.
Once you have enough loose material to make the ruts disappear, the best way to smooth it out evenly is to shorten the top link until the leading edge of the blade is straight up. Run in 3rd or even 4th gear, so the angled blade can throw material over the crown of the driveway. If the tires are slipping, shorten the top link more. Continue to run with the leading edge of the angled blade at the edge of the drive. This is how we create a crown so water will run off the driveway. The final passes can be done with the blade turned around backwards as previously described.
Gravel comes in many sizes and types. Experiment with the top link to find the length that works best for your gravel. Too much speed will get the blade bouncing, and dump whatever it is carrying. This makes rumble strips. That is not usually what we are going for. The ideal driveway surface is smooth with a slight crown, so water will run off. Done right, the driveway should pack down into a stable surface that only needs a touch-up two or three times a year.
Front Blade or Rear Blade? Is it better to push or pull snow?
The answer depends a lot on your equipment. First we have to answer a whole list of questions like:
How good are the tires?
Are the tires filled?
Do you have tire chains?
How wide is the blade?
What do you consider DEEP snow?
How long is your drive?
The correct answer will vary depending on your equipment, and what you are asking it to do.
If I just want to move 4-6" of typical Virginia snow/slush, so it won't pack down and turn into ice, I turn the blade backwards, angle it to the second or third setting, shorten the top link, and drag it in 3rd gear (8N 4-speed tranny) so it spills the slushy stuff just off the edge of the drive. Dragging the blade backwards won't disturb the gravel nearly as much. If the blade rides up on top of the snow/ice, slow down, or lengthen the top link to stand the blade a little more vertical.
For a heavy 8-10 inch Virginia snowfall, I prefer to use the 2N. It has filled tires for better traction. Typical Virginia snow is very wet, heavy stuff. It makes great snowballs, but is hard to plow. I turn the blade around the right way, extend the top link as far as I can, and put skid shoes on the blade, so it can't dig-in. I'm running forward in 2nd gear (3-speed tranny), with the blade angled as much as it will go. This set-up will use the curved shape of the blade to pick up and roll the snow off the drive. Clean the blade and spray a little PAM on it to help the snow roll and slide along the blade.
Even with filled tires and chains there is a limit to how much snow you can plow before the tires are slipping too much. Control tire slip by raising the blade slightly. It should be possible to do this automatically, with the lift set in DRAFT mode, but I've not had much success with that. I suspect the top link needs to be in one of the upper holes. I hope we don't ever have so much snow that I get good at setting the lift up to plow snow using DRAFT mode, grin. I do ok controlling wheel spin manually with the touch control lever.
A few years ago I was wishing for a set of tractor tire chains. Virginia doesn't usually get back-to-back 12" plus snowstorms, but we did that year. The snow I'd already plowed was blocking the edge of the drive, and I couldn't get enough traction to plow the whole mess further over. All I could do was turn the blade backwards, plow in reverse, and use the lift to push snow up and over the edge. I gradually worked my way down the driveway, 20 feet at a time, pushing what I had on the blade over the edge into the woods. We have family in Minnesota who just shake their heads when their southern relatives talk about a big snowstorm. People who live in Virginia have never seen a "real snowstorm". OK, if you live where snow falls more than a foot deep, every year, the best advice I have is to move further south. For advice on dealing with snow measured with a yardstick, get tips from friends and neighbors who have been thru a few winters. It is March 2018 as I write this update, and looking like we will get thru this season without a major snow storm. Perfect.
Here's a deluxe snow removal machine. Maybe one of your neighbors is named Matt?
Some rear blades have additional adjustments. One of my blades can be offset to one side. This feature can move snow well off the edge while the tractor stays on the driveway. The offset blade is also good for clearing ditches.
The box blade is probably a better implement for working a badly rutted driveway. The teeth loosen material and the box helps lay the material smoothly. The box prevents material from spilling past the edges. I don't have a box blade, but I've used one.
This is a two-bottom plow, the main implement N-Tractors were designed to use. The N-Tractor Operator's Manuals have a plow section in the back. This has all the basic information necessary to attach and set-up the plow. Other details are entirely dependent on your soil type, specific plow, and the crops you plan to grow. Talk to a few local experts.
Draft control is for plowing and a few other "Ground Engaging" implements. If the implement does not dig into the ground, move the small lever UP and use Position Control. The correct way to operate the lift when you are plowing is to move the small Draft Control Lever down to the Draft Control position. Slowly push the Touch Control Lever down. The plow should drop to the ground. STOP moving the Touch Control Lever. Start moving forward and let the plow work. The plow should go into the ground a little and continue running at that depth. Continue to push the Touch Control Lever down in small increments until the plow is running at the depth you want. Loosen the wing nut and move the Touch Control Lever stop to mark this position on the quadrant. Now, every time you lower the Touch Control Lever to the stop, the plow will run at the same depth.
Draft control is hands-free for plowing. When the plow hits denser soil, the additional resistance would normally cause the tractor tires to slip. Without draft control, the operator would have to manually raise the plow slightly to keep the tractor moving forward. Draft control constantly varies plow depth in small amounts so there is minimal wheel spin. The operator can now concentrate on driving straight furrows.
This is an old single row pin hitch disc converted to 3-point. These tractors will also pull my 5-foot wide, two-gang disc. These are my favorite landscape and garden tools. For many areas, there is no need to go any deeper than a few inches, and a decent disc plow will go at least that deep in most soil. This is another implement that seems to work best after some rain. All of my disc plows are adjustable. The rows of discs can be set to run straight, or angled. In the angled position they cut deep and turn top soil and growth over. Turned to run straight, the discs break up and smooth the ground to make it ready to plant. A tiller can make a planting bed in one pass, but I have more fun running in second or third gear with the disc plow.
A friend once gave me a tiller attachment for free. It was a Howard Rotavator, made to bolt directly to the N-tractor PTO flange. The big problem with any tiller is the 8N ground speed in first gear is way too fast. I tried every combination of gears in the Sherman Combo with no success. The Howard tillers were sold with a Howard step-down transmission that was installed in the drive-line between the transmission and rear axle. The Howard step-down transmission slowed the tractor without affecting PTO shaft speed. My free tiller attachment did not come with the transmission accessory. The Howard step-down transmissions are very rare and expensive. By the time I found one of the step-down transmissions, I was completely done with the tiller, and had given it away to the next victim. My conclusion is that a solid-mounted tiller attachment will beat you and the tractor to death, unless it is working soil so loose it doesn't need to be worked.
The cultivator can be used to prepare a seed bed before planting, but is more often used to disturb and kill weeds between rows of crops. The tines should just scratch out the weeds without disturbing crops. Use of cultivators for weed control has been on the rise with the popularity (and premium price) for organic produce.
A landscape rake can be used to move rocks, roots, and trash after the ground has been worked with a bottom plow and/or disc. There are several powered rock pickers that will do a better job in a shorter time. Rocks tend to get pushed to the surface each winter as the soil freezes and thaws, so rock picking is an annual chore in many fields.
This attachment is getting hard to find. There is little or no demand for them. Most new tractors now come with front-end loaders. Many a farm pond was scooped out with a 3-point dirt scoop, but the modern tool for that type of work is a front-end loader. The dirt scoop can be filled by pulling it into the ground, or it can be mounted backwards and pushed in reverse gear. Pushing something like this in reverse is a great way to bend one or both lower lift arms. The N-Tractor lift was designed to pull, not push. Using stabilizer bars helps brace the lower lift arms as well as keeping the scoop centered between the tires.
The dirt scooop works better than expected and holds about 1/4 cubic yard. That digs much faster than any hand shovel, and is a lot easier on my back. It was suprising how well the scoop is balanced. Dirt in the scoop causes it to dump when the release lever is tripped. As soon as it empties, the back of the scoop becomes heavier, so it falls back and latches. Creative use of reverse gear while dumping allowed the lip of the scoop to be used as a vertical blade to spread the dirt before allowing it to fall back and reset.
Flooding washed-out our little covered bridge that provided access to about an acre on the other side of the creek. Rather than try to rebuild the bridge across a much wider creek bed, it seemed better to cut a ramp. This ramp was scooped-out in a couple hours by dragging the scoop from as close as we could safely get to the edge. Do not get so close that the bank can collapse. The scoop digs a big hole in a hurry and easily cut thru some fairly large roots. Then the dirt scoop was turned around so it could be filled by backing towards the creek. Surprisingly little dirt actually fell in the creek when we broke thru. Running the Sherman in low range definitely helped provide more torque to do this job.
The best description of these is a trailer without wheels. They attach to the 3-point lift and some have a trip lever to dump. Most of these are built by the owner. Anything that can do more than one job is better. A set of pallet forks is always nice to have. These were welded together from 3x3 and 2x3 tube steel. Then an old garden trailer box was bolted to the forks.
The carry-all was ok, but what do you do when the cutter is on the tractor? Why not weld some mounts and bolt the carry-all box on the cutter?
Most any sort of box will work if you can come up with a way to hang it on the 3-point lift.
Some people like a front blade, but the N-Tractors are not well suited to having anything on the front. The front axle is weak, and the steering does not improve with additional weight on the front tires. There were some nice front blades made for the N-Tractors. Most of them use cables attached to the tractor 3-point lift to raise the blade. Very few have the ability to apply any down pressure to the blade.
This cutter is a 5-footer that I rebuilt. The chains were added in front to try and stop it from throwing sharp sticks at me. Some cutters come with a similar front guard. These didn't work well and were replaced with a piece of used conveyor rubber. The reinforced rubber does a great job of knocking down the missiles that a cutter launches. For its size this cutter is fairly easy to maneuver on our woodland trails. The rear corners are cut on a diagonal. The diagonal corners slip past obstacles much better than other cutters that are just a big square box.
SET UP FOR TRAIL MOWING
My "tree pusher" bumper worked well. This version used a couple pieces of unistrut that were bolted directly to the cutter and braced a heavy piece of 2" x 3" tube steel under the factory front bumper. Something like this is much better than knocking down trees and brush with the grille or radiator.
Implements such as blades and plows just attach to the 3-point lift, and get dragged or pushed, nothing fancy about that. Now we take all the setup and tricks we learned, and add a connection to the tractor PTO. If you plan to cut tall hay, with a 6 foot cutter, look for something like a Ford 2000, 3000, or 4000. They have twice the horsepower in a tractor that isn't much larger than the N-Tractors. The thousand series were also available with gasoline or diesel engines.
One problem running a cutter with the N-tractors is they do not have live PTO. There is no way to slow the tractor when you get into really deep stuff that doesn't also slow or stop the blades. Riding the clutch does not help much since it also reduces power to the blades. Another worse problem is the energy stored in rotating blades will continue to drive the tractor forward every time the operator tries to slow down or stop quickly. There is no way to describe the helpless feeling when we step on the clutch, apply the brakes, and the tractor continues to drive forward through a fence, up a tree, or into a ditch. The accident is often completely finished before anyone can try to knock the transmission or PTO out of gear.
The solution to the second problem is to use an overrunning clutch. The overrunning clutch allows power to be applied to the cutter, but when the tractor slows down, the clutch ratchets and allows the blades to spin free, rather than drive the tractor forward. This is a huge safety improvement! This overrunning clutch can also serve as the adapter needed to match up the 1-1/8" spline tractor PTO shaft to the cutter which is most likely going to be a modern 1-3/8" spline. There are PTO replacement shaft assemblies that have the newer 1-3/8" splines, or we could use a 1-1/8" to 1-3/8" adapter. I am using a 1-1/8" to 1-3/8" overrunning clutch adapter to run my cutters.
If you are considering the replacement 1-3/8" PTO shaft, buyer beware. There have been many cases where a cutter hit something and bent or broke the PTO shaft. A bent or broken PTO shaft can be a real bear to extract from the tractor innards. That project may require splitting the tractor to get the broken parts to come out. In every case that I've heard of, the bent or broken shaft was one of the modern 1-3/8" replacements. Some have said that the original shafts were higher quality steel or there was better quality control of the heat-treating process. Either or neither may be true. I don't know, but used original 1-1/8" shafts always seem to be available on eBay, so I will keep using the original shafts in my tractors.
With the overrunning coupler in place, we can operate the cutter much more safely. We still have no way of momentarily slowing the tractor forward speed when we get into deep grass. Our only options are to raise the cutter a bit, steer to cut less width, or pick a slower gear for the whole job. This isn't exactly the end of the world, I use all of the above methods in different places on our property.
GET A SET OF LIMITER CHAINS These chains can be adjusted, so when we lower the cutter, it stops at the cutting height we want. This is far superior to trying to hold the proper height with position control. The 9N 2N tractors don't even have position control. Once the chains are holding the cutter, drop the touch control lever to the bottom and just cut. When the lift pump broke on my 2N, I used a floor jack to get the cutter hanging on limiter chains and ran the cutter that way for several months before bothering to fix the hydraulics.
This is a typical set of limiter chains for the 5 foot cutter on my 8N. Cutting is MUCH easier once these are set at the correct cutting height.
This is the 8N paused after cutting the closest thing we have to a field, next to the neighbor's stock fence.
CUTTER SIZE These tractors will run a 4 or 5 foot cutter through most types of grass and brush with no problem. The 4 foot cutter is much easier to manage in tight quarters and may be the better choice for cutting hay. The 4 footer is lighter, easier on the tractor, and easier to hitch up. The 5 foot cutter will cover your track width better, so you can cut closer to things like fence lines. The 5 foot cutter will also store more energy in its heavier blades, so it may power through saplings better. Do your research and choose the cutter that will work best for you. Or you could do as I did and buy whatever you can find used. I ended up with both a 4' and a 5' cutter.
Hook the cutter to the 3-point as you would any other implement, but do not connect the drive shaft yet. Take the mower to a level spot, and adjust the limiter chains. Once you have the cutter hanging on the limiter chains, kill the tractor engine, and adjust the tail wheel so the leading edge of the cutter will run about 1/2" to 1" LOWER than the rear. Adjusting the leading edge slightly low will allow you to cut just about anything with the least horsepower = less fuel used. Once the cutter is properly mounted and adjusted hook up the drive shaft. The overrunning coupler should be installed on the tractor PTO shaft first. Most have a pin that is captive inside the housing. That may require a hammer and punch to install. Caps or grease fittings usually cover the pin. Refer to the instructions for proper installation and lubrication. The implement driveshaft soupling will usually have a spring-loaded pin that is depressed and then pops out when the shaft is fully engaged and locked on the overrunning coupler. Make sure everything is properly attached. If this comes loose under power it will flop around with deadly intent. Think about what a chunk of broken drive shaft might do if it hit you in the back of the head!
PTO SHIELDS All modern cutters will have a PTO shield over the drive shaft. The shield should be connected to something stationary at both ends so the shield does not spin. Enclosing that dangerous rotating shaft is a very good safety feature. My ancient cutters did not come with shields. TSC sells them, but attaching the ends will probably leave some portion of the PTO coupler or drive shaft universal uncovered. Even so, my shield covers all of the shaft and will certainly help keep anything from getting wrapped around the spinning drive shaft. Regardless whether or not your PTO is shielded, ALWAYS STAY COMPLETELY AWAY from the shaft and cutter whenever it is turning. Even if it's just winding down. Never leave the tractor seat while anything back there is moving (PERIOD). Spinning PTO shafts are perhaps the most dangerous part of any tractor. The spinning shafts can instantly latch onto clothing, and will wrap whatever is in the clothing around the shaft at 540 RPM, That's nine revolutions per second! Step a little too close to the cutter and a blade can ruin your foot.
Even a 4-foot mower puts the tail wheel a long ways behind the back tires. Even if your property is mostly flat, you will need some flexibility in the top link. A rigid top link will try to hang you up with the rear tires spinning in air every time you drive through a low spot. Both of my cutters have some top link flexibility built-in. One has a 3" slot that the top link attaches to. The other cutter has the entire top link "A" frame hinged. Chains prevent the "A" frame from moving forward too far, and allow it to move back about 6". The top link should float within its range of adjustment most of the time you are cutting. Do not ever completely replace the top link with a chain. If the front edge of the cutter should hook something, the entire cutter could rotate on the lower links and whack you on the head. Unless you are running way too fast for the terrain, the top link should prevent the cutter from flipping up far enough to be a danger to the operator.
TREE PUSHER Even if your tractor has a bumper, it likely doesn't offer adequate protection for cutting small trees and heavy brush. My 5 foot cutter can chop just about anything I can push over with the tractor. Pushing through small trees will seriously abuse your headlights and quickly wear all the paint off the leading edges of the tractor. I've tried several versions of my tree pusher. The bumper should be wide enough to protect the entire front end, but not stick out and hang on things when backing up.
One of the first things I noticed with my cutter was how much more stable the tractor felt with all that weight hanging down low. The cutter adds a tremendous amount of traction and stability. The only disadvantage is when running up a hill. The front tires can get very light. Be prepared to steer with the brakes. That is why you have two brake pedals.
Don't expect a nice smooth lawn when you finish cutting using a rotary cutter. The rotary cutter uses fairly dull blades to bash and smash through brush and trash. They are not intended to cut clean. I've sharpened the blades a bit more than recommended on mine. It now does a better job on grass, but it will never come close to a finish mower.
A finish mower is easy to spot. Rather than just the one tail wheel, they will have adjustable gauge wheels at each corner. The set-up and warnings for a rotary cutter also apply to the finish mowers. You won't want limiter chains, the four gauge wheels take care of the cutting height. Just let your lift all the way down and go. A finish mower uses lighter blades that spin faster to cut better. The light blades store much less energy. It will take more horsepower to run a finish mower than the same size rotary cutter. How wide you can go depends on what you are cutting and how often you cut it. In most cases a 4 foot finish mower is going to be the best choice for these tractors unless you plan to cut often or take less than a full row each pass. There are people who say these tractors will run a 72" finish mower. Watch them work and they are probably only making a 48" cut with each pass.
This is another one I've wanted, but don't have yet. The N-Tractor lift does not have down-pressure, so we need an auger bit that will pull itself into the ground. Gravity helps. It also helps if the unit has a reverse gear, so the bit can be easily backed-out when it gets hung up. Twist a bit around a rock or tree root with no reverse gear on the post hole digger, and you might spend the rest of the afternoon digging with a shovel to make that hole big enough to pull the bit out.
Same comments as for the front blade. Some of the loaders that will work on the N-Tractors use the tractor hydraulics to slowly raise the bucket. Others add a front pump that runs directly off the engine crankshaft. Some pipe framed loaders make it very difficult to get on and off the tractor. Most loader frames make common maintenance much more difficult. All loaders add significant length to the tractor and greatly reduce rear wheel traction. Raising the bucket, especially a loaded bucket, raises the tractor center of gravity. It is much easier to tip the tractor with the bucket in the air. The weak front axle will require much more frequent maintenance. With no power steering the tractor will be hard to steer even with just the added front weight of the loader and bucket. The workout gets worse with each pound of material scooped into the bucket. Most loaders will be very difficult to attach and detach from the tractor. Loaders are not implements in the sense that they can be easily removed and replaced with something else.
There, that is all the reasons I don't want a loader on my N-Tractors. Why do most new tractors come with a loader? Because they are incredibly convenient! "Once you have a front loader you use it for everything and don't know how you ever got along without it." That may as well be a direct quote from the last 25 people I've asked. I don't have a loader, so I'm blissfully ignorant and don't have a clue what I'm missing.
There were a few backhoes, such as the Sherman Power Digger, that were made for these tractors, and work well. Maybe you can find one of those. Most new aftermarket backhoe attachments will need a front loader to balance the package. Very few, if any, backhoes are truly "attachments". They are usually very difficult to attach and remove from the tractor. Some require making modifications to the tractor, such as removing the 3-point lift.
Another issue is the tractor hydraulics are only rated at about 2 GPM. The pressure is fine, but the flow is way too low to operate an attachment with 6 or 7 hydraulic cylinders. The tractor sump is also only 5 gallons. This may be barely adequate to prevent overheating of the fluid. The average backhoe sump holds more like 10 gallons. So a backhoe should have a bigger pump and probably should have its own hydraulic sump. The pump can be engine driven as is often done for loaders, or a rear PTO pump can be used.
My backhoe works well with the N-Tractors. Mostly because it was specifically designed to work with them. My backhoe attaches to the 3-point lift arms, which help to locate it properly on the tractor, but it does not depend on the 3-point for lift or support. The backhoe has its own sub-frame that attaches rigidly to the tractor at three points. Unlike most others, my backhoe is no harder to attach and remove than any other large, heavy implement.
My backhoe attachment has its own web page, BACKHOE If you are interested, follow that link.
The 8N tractor may be the most heavily modified tractor ever made. Maybe not, but a lot of people have spent a lot of time modifying them. This is just a partial list of some accessories I like.
Lights - Head lights, Tail lights, and Work light are nice to have. Tail lights might keep someone from hitting you if you must use a stretch of road. Modern LED lamps use very little power and will light up the night even with the minimal power available from the original 6 volt system.
Foot Throttle - Drive it like a car with a foot throttle. This is really nice to have when running a blade or just hot-rodding around.
More Power - There have been 6 cylinder and 8 cylinder conversions. There's even a jet-powered N-tractor. Here's a link to my V8-8N project, 1951 V8-8N (work in-progress). If you are really interested in engine conversions don't miss a visit to Marvin Bauman's web site at: marvinbaumann.com. He has done several different first-class conversions.
Cup Holder - An essential addition, no matter what your beverage of choice may be.
Live Hydraulics - Add a front pump and a couple of hoses and you have full time live hydraulics. Now the lift will go up even when you have stepped on the clutch pedal. Check out my page on Live Hydraulics.
Roll-Over Protection System - It is possible to build your owne ROPS. NIOSH CROPS Somebody at USA.GOV saw the need and responded. Sadly the result falls short of what should have been. Rather than using any of the existing simple, easy, factory-built designs the overly complicated NIOSH CROPS design appears to be based on a fear of welding. However the NIOSH CROPS still requires some welding and requires access to equipment capable of making 90 degree bends in 1/2" plate steel! Many people have managed to build safe, affordable roll bars for off-road vehicles. Most off road vehicles are less weight than even a small tractor, but generally travel at much higher speeds.

Parking Brakes - These tractors have tiny little parking brake pawls that you practically have to do a headstand to use. Some implements dropped on the ground make a more convenient and effective parking brake. Red Rock sells a reproduction of the Farmec lever-operated parking brakes. I bought a pair for my 8N, then decided to split the set and mount one of them on my 2N. I never bothered to set more than one of the original pawls, so saw no need to have brake levers on both sides.
Umbrellas, Canopies, and Cabs - If you work in the sun or plow lots of snow, one of these options may appeal to you.
Second leveling box, Auxiliary Transmissions - more gears is always a good thing, half-tracks, the 8N crawler version, etc...
