What is Tractor Pulling?
Tractor pulling competition is when a special-built weighted pulling vehicle or tractor pulls (or drags) a mechanical weight transfer machine, which is more commonly known as a "sled," on a dirt (clay) track of a specific distance, which is usually a maximum of 300 feet in length. As the vehicle pulls the sled down the track, ballast (weights) that's in a box which is positioned at the rear of the sled is automatically transferred (mechanically winched) forward on the frame of the sled. This transfer of weight, or ever-increasing of weight, creates friction between the skid pan (that's part of the front of the sled) and the ground, and that in turn makes the sled harder to pull, eventually stopping the vehicle. The winner is determined by not how fast a pulling vehicle goes down the track, but who drags the sled the farthest. In other words, it's not a race, it's a pulling event.

Garden tractor pulling can be a fun and safe sport for the entire family. If done fairly, garden tractor pulling helps build good character and sportsmanship in people of all ages. Sports has always been considered a healthy outlet for young people. A chance for young people to learn how to win or rather lose. But most importantly, how to play by the rules, which help keep them out of trouble at home and with the law. Kids also need proper parental guidance so they can live a happier, healthier and more fulfilling adulthood. I think this is a good sport for people of all ages (as long as they can safely operate a tractor). Sons, daughters, nieces, nephews and any other kid who has gotten bored and are running the streets too much. If you have the means to spend some money to help kids go down the right path and have good clean fun, then garden tractor pulling is for you and your family. Not only the young can enjoy garden tractor pulling, but older folks can enjoy it, too. It gives retired people a good excuse to get out of the house, and keep their mind and body active.
Garden tractor pulling is a sport, just like any other sport. Some people like to go fishing. Some play golf at a country club. Others do tractor (or truck) pulling. All of these activities are considered sports, which is supposed to be fun and relaxing. If a tractor does well at a pull, and if there's prize money to be won, most of the time the prize money usually isn't that great. In fact, the winner would be lucky to make gas money. But it's fun to compete, test your mechanical skills on the tractor and driving skills on the track. Garden tractor pulling is not only appropriate for the whole family, but actually makes people feel encouraged, inspired, and challenged. It's also a good excuse to get your mind off your daily job and routine life, and it's a good reason to get away from home for a while, like a short vacation. And if you think about it, it's mental therapy or a great stress relief. It's an "escape" to maintain yours and your family's or friend's sanity. Also, tractor pullers from various areas are like one big family, not bound together by blood relation, but by a common interest. Many of them are hard working, honest people that have a family to support.
The sport of pulling can be a fun and exciting family activity. With a reputable pulling club/association, garden tractor pulling can be a lot of fun for the entire family and/or with friends and very affordable. Just a reliable average pickup truck and a small- to medium-sized utility trailer is all that's needed to haul the garden tractor(s) to and from the pulls. Garden tractor pulling also helps to bring families and friends closer together. It also help build a strong relationship between parents and their kids. A broken tractor is much easier to fix than a broken family. Besides, if you don't spend time with your family and kids now, then perhaps one day you'll wish you did. Anyway, you and your family/kids and/or friends get to travel to other towns or communities, see the beautiful countryside and interesting sights along the way while on the road, meet interesting people, have a chance to be with other pullers who share your interests and make new friends, you can dine at nice restaurants, even stay at a motel before or after a pull! Traveling to and from a pull should be half the fun! As they say, it's not just about the destination - it's about the journey. While at a pull site, if it's at a county fair, there's usually other activities also. Early before the pull begins or when the pull is over (if it's not too late), you and your family can walk around the fairgrounds to see the sights, and your kids can go on the carnival rides. The rides are usually free, because most of the time there's free admission [for pullers and helpers] to the fair! And please remember, ALWAYS drive carefully, get plenty of rest before starting a long trip so the driver will be alert for unexpected events while on the road, and definitely wear your seat belts!

Always Wear a Helmet When Pulling!
I know for a fact that some pullers don't wear a seat belt in their vehicles while traveling or on their way to and from the pulls. (Safety must be the last thing on their mind.) But unlike seat belts, wearing a helmet isn't only for safety, it makes the puller look PROFESSIONAL to the sponsors, promoters and spectators! Tractor pulling is a spectator entertainment sport, or show business. And to put on a good show, you gotta dress for the part!
And if the sanctioning rules require that long leg pants and closed-end shoes be worn when pulling, if a puller wears shorts, and complain about the summer heat, they can just slip on some sweat pants and closed-end shoes, and then go pull. As long as their legs and feet are covered, that's what matters.
And during the hot summer heat, sometimes tempers will flair at a pull site. It's just human nature. This is something track officials and pullers need to take into consideration when confronting a disgruntled puller. When this happens, just tell them to drink some ice water, go cool off, calm down and gather your thoughts. Because they're not being themselves. It'll be wrong to get upset at them. Because when you're an official of a club, you must delegate authority responsibly.
If you're looking for a quality garden tractor to build up and do some serious pulling with, then what you need is a beltless, non-hydrostatic drive, clutch-driven, manual shift Cub Cadet that was built by International Harvester and the early ones built by MTD (Modern Tool & Die). The best Cub Cadet garden tractors for competition pulling are clutch driven. These models include:
The differences between Cub Cadet frames:
How to Make a Hydrostatic Drive Garden Tractor a Competitive Pulling Tractor -
Replace the OEM Cub Cadet Charge Pump Relief Spring (by-pass/pressure relief spring) with one that's twice as stiff or much stiffer than the original so when the tractor (hydrostatic system) is under a severe strain, oil pressure will not by-pass the hydraulic motor and return or circulate back to the hydraulic pump. In other words, doing this will allow much more oil pressure to be applied to the hydraulic motor. On Cub Cadet models with a PORTED pump, the Charge Pump Relief Spring is located under the plug on the LEFT SIDE of the hydrostatic pump housing. And on NON-PORTED pumps, the spring is located under the plug in the CENTER of the hydrostatic pump housing. See pictures below Ê. Also, the use of [heavier velocity] SAE 30 weight hydraulic oil will help increase the pressure. And the tractor will definitely need a healthy or bigger engine, preferably one that's built to the max to increase the torque. By the way - I don't know which spring works the best. You'll just have to shop around for one that works.
But any hydrostatically driven IH or MTD Cub Cadet garden tractor can be easily converted into a clutch drive tractor using the transaxle and clutch/driveshaft components out of a clutch drive "parts" tractor, as long as the frames on the donor and recipient tractors match. IE: a narrow frame for a narrow frame, a wide frame for a wide frame and a spread frame for a spread frame. The transaxles for all IH and early MTD Cub Cadets are basically the same, rather if it's an internal or external brake design. The bolt holes in the hydrostatic drive and clutch drive tractor frames are the same, too. The clutch/driveshaft components must match the frame of the donor tractor to be converted. For example: to convert an IH Cub Cadet wide frame model 109, 129, 149, 1250, 1450 or 1650 into a clutch/gear drive, the complete clutch assembly with the throw-out bearing release lever and cross bracket, and transaxle from either an IH Cub Cadet model 86, 108, 128, 800, 1000 or 1200 must be used. The brake components will also be needed from these tractors.
Most IH-built Cub Cadets come from the factory with a cast iron block, K-series Kohler engine. And almost every late model of the spread frame Cub Cadet that's made by either IH or MTD are hydrostatically driven, with the exception of models 582, 1050, 1535, 1606 and 1806 which are all clutch driven with a durable and light-weight MTD-built aluminum case transaxle.
Unlike the IH and early MTD Cub Cadets, most garden tractors that's built nowadays won't be in use 30-40 years from now. They're just not built that good nowadays. This is a well-known and proven fact. The older Cub Cadets (and Kohler engines) were built back when most manufacturers took pride in their products. Nowadays, it's all about American businesses making more money with Chinese negotiations. If you ever restore an old Cub Cadet so it's fully operational, you'd probably fall in love with it. Because I think any new garden tractor that's build nowadays can't match the durability and capabilities of the older Cub Cadets. Besides, International Harvester builds big farm tractors and semi-trucks, and they put all that heavy duty technology in their smaller products. Once you use an older Cub Cadet for whatever purpose, you'd be reluctant to use anything else. The quality is unmatched to any other make of anything else. Cub Cadet is the "Chevrolet" of garden pulling tractors (you know what I mean ). If you do find an older Cub Cadet that's worth the money, and despite the condition it's in, just remember that it is worth repairing or restoring. It'll be like restoring an old Chevrolet (again, you know what I mean ).
Remember, when building and/or acquiring a pulling tractor, remember - it's best to use what the winners are using - a direct clutch drive (no belt involved) Cub Cadet and use the biggest engine your club's rules allow in its tractor's class. The best Cub Cadet model to use is either: 70, 71, 72, 73, 86, 100, 102, 104, 106, 108, 122, 124, 126, 128, 580/582, 682, 782, 800, 982, 1000, 1050, 1200, 1282, 1512, 1535, 1606 or 1806. And there's sanctioning rules with every pulling club/association regarding how a tractor should be built or set up. Not all clubs use the same sanctioning rules and specifications. The rules vary from one club to another. You'll need to contact the person in charge of the club you plan to pull with and acquire a copy of their up-to-date rules and ask their pullers questions before you build a tractor. And while you're at the pulls, look over the pulling tractors and ask the pullers questions regarding how to build a durable and competitive tractor. And remember - if you're going to build it, you might as well build it to win! Go here to find a pulling club near you: Hot Links to Various Garden Tractor Pulling Clubs and Associations.

The IH Cub Cadet production ended and the line was sold to MTD/Cub Cadet
Corporation in June 1981.
The serial number is located in one of the following locations...
NOTE: The model number of the tractor represents horsepower of the engine, and if it's clutch or hydrostatic drive. Odd numbers are hydrostatic (fluid) drive, and even numbers are clutch (mechanical) drive. Example: Model 104 has a 10hp engine with a clutch drive transaxle, model 105 has a 10hp engine with a hydrostatically driven transaxle, model 122 has a 12hp engine with a gear drive transaxle, model 123 has a 12hp engine with a hydrostatically driven transaxle, etc. The only exceptions are models 71 and 73. They have a 7hp engine, but they're both gear drive. Why that is, I have no idea.
The "wide" frame models can only accept a single cylinder engine. The "spread" frame models can accept either a single cylinder or a twin cylinder engine because the frame rails were made wider and they lay down more to clear the cylinders of a flathead twin opposed cylinder engine.
FYI - As far as a single cylinder Magnum engine in a Cub Cadet is concerned, only the single cylinder Kohler K-series engines was installed in Cub Cadets at the factory. No Cub Cadet came from the factory with a single cylinder Magnum engine. When Kohler ended production of the K-series engines, and redesigned them into the Magnum engines in 1979, it wouldn't fit in the narrow or wide frame Cub Cadets, so instead of Cub Cadet redesigning their tractors to accommodate the single cylinder Magnum engines, they made the spread frame models instead and used the twin cylinder flathead engines. Only a few remaining NOS (new old stock) single cylinder K-series engines was installed in certain spread frame models after 1979. When the stock ran out, Cub Cadet ended production of those models. That's why there wasn't too many of them made.

How to Make a Hydrostatic Drive Garden Tractor a Competitive Pulling Tractor -
Simply install a set of much stiffer matching pressure relief springs in the hydraulic valve assembly so when the tractor (hydrostatic system) is under severe strain, less oil pressure will by-pass the hydraulic motor and return or circulate back to the hydraulic pump. In other words, this will allow more oil pressure to be applied to the hydraulic motor. Use SAE 30 weight hydraulic oil to help increase the pressure, too. And the tractor will definitely need a healthy or bigger engine, preferably one that's built to the max to increase the torque.
If you decide to build a pulling tractor, and if you want to be competitive, then it's best to use a clutch drive Cub Cadet. Also, there's sanctioning rules with every pulling club/association regarding how the tractor and engine should be built or set up. Not all clubs use the same rules and specifications. Rules vary from one club to another. You'll need to contact the person in charge of the club you plan to pull with and acquire a copy of their up-to-date rules and ask their pullers questions before you start to build a tractor. And while you're at the pulls, look over the pulling tractors and ask pullers questions regarding how to build a durable and competitive tractor. Most pullers will be honest with you, while some will give you misleading information, which I think isn't right. In this competitive sport, use your best judgment and don't believe everything you hear from other pullers.
If you don't want to embarrass yourself in front of the spectators, then don't waste your time, money and materials on something less than a true-to-it's-name garden tractor. Stamped steel frame lawn tractors (MTD, Murray, etc.) simply cannot compete against the power and torque or muscle of a true garden tractor. If you want to win or at least do well at the pulls and look good doing it, then get yourself a clutch-drive Cub Cadet, and use the stamped steel frame lawn tractors to mow your lawn with. Or adapt the lawn tractor sheet metal (hood, grill, fenders, steering support column, etc.) onto a Cub Cadet chassis.
To be competitive in garden tractor pulling, what you need is a garden tractor that has an automotive-type frame, horizontal engine, a cast iron transaxle and 12" diameter, 5-lug rear wheels. It can be belt drive, too. Look for a good-size Wheel Horse or a Sears Suburban. They're the most popular and least expensive to build up for pulling in a stock class. Fact is, the drive belt on some garden tractors robs the engine of power. The Cub Cadet on the other hand use a direct drive clutch/driveshaft system, which is much like the ones that's used in automobiles. You get more power to the track with a Cub Cadet. Belt-driven garden tractors, such as Wheel Horse, Sears Suburban, etc., do very well in the stock classes with a limited horsepower engine, but if you want to move up into a more powerful or highly modified class, the Cub Cadet is the only way to go. They've been proven to be the most competitive garden tractor for pulling that's available.
Certain models of John Deere and Massey Ferguson garden tractors have a variable speed control called a "variator," which is a factory-installed lever positioned on the right of the steering wheel. Most Cub Cadet pullers call this lever a "cheat stick." When it's pulled back, it slows down the tires to reserve engine power and torque. When used in competitive pulling, this feature allows the tractor to have plenty of ground speed upon takeoff and go down the track with plenty of ground speed, and when the weight of the sled comes up on the tractor, and if the engine begins to bog down or lose power, the operator can pull back on the lever, slowing down the tires, so the engine will have more reserve power to "chug, chug" a little further down the track without running out of horsepower. It works great in the stock class(es), but being it's part of a belt-drive drive system, the tractor may lag behind in a higher horsepower class with a wide open throttle engine.
And the reason there's different classes for pulling tractors is because some tractors come with a bigger engine and some weigh more than others. A tractor with a big engine will undoubtedly out-pull a tractor with a small engine. And the same goes for a tractor that weighs more than the others. Therefore, most pulling clubs try to match the engine size and the weight of any particular tractor (with the driver) so they'll be competitive within their class.
Ever noticed how there's always more Cub Cadets at the pulls than any other make of garden tractor? That's because the Cub Cadet is capable of transferring more usable horsepower and torque to the rear tires through a unique direct-drive disc clutch system much like the ones used in automobiles, farm tractors, etc. And, there's more high performance parts readily available for the IH Cub Cadet and Kohler engine than any other make of garden tractor or engine.
One of the most popular bodies to adapt onto an IH Cub Cadet frame is from certain models of John Deere garden tractors. The reason for this is many pullers like the John Deere so well, but sometimes they can't out-pull a Cub Cadet. So they create a "generic" John Deere garden tractor. That's when the John Deere body parts are integrated onto a Cub Cadet frame. The Cub Cadet frames that's suitable for the John Deere body parts are: 102, 104, 105, 106, 107, 122, 123, 124, 125, 126, 127, 147 (narrow frames; because these models have the tall center section), and any wide or spread frame model. If the JD body parts are installed correctly and the entire tractor is painted the traditional JD green and yellow, the tractor will have the appearance of a genuine John Deere, but the pulling components and power of a Cub Cadet. Many pullers do this. Like the old saying goes: "If you can't beat 'em, join 'em!"
Ever noticed at the pulls, how many genuine Cub Cadets show up, but very few John Deeres (or is it pronounced "John Deere"? hmmm) are there? With a generic John Deere doing well at the pulls, this puts the Deere name out front. Hence, "Nothing runs like a Deere!" But nothing pulls like a Cub Cadet!
One thing about the Cub Cadet is, they're so versatile! It's so easy to adapt wheelie bars, an adjustable pulling hitch, and many other things to these tractors without having to make any major modifications to the frame.
Of course, the body components of other makes and models of popular garden tractors, such as Wheel Horse, etc., can be integrated onto a Cub Cadet frame as well. It just takes some time and effort to figure out how to adapt the parts so it'll look original.
Most rules require "a garden tractor frame." Therefore, most pullers prefer to use the later model "wide" and "spread" Cub Cadet frames. They're strongest frames for use with a high horsepower engine. They're more rigid and flex less than the older narrow frames. Frame flex absorbs horsepower and torque, which must be transferred to the ground through the rear tires. The "wide" frame were originally manufactured to make room for the small gear starter and large flywheel on the 10hp-16hp single cylinder Kohler engine. And the "spread" frame were originally manufactured for a twin cylinder engine, but a single cylinder Kohler engine can be easily installed with no adjustments.
The manufacturer didn't exactly design the Cub Cadet (or virtually any garden tractor) to be fitted with a powerful engine, being weighted down, using 26-12.00x12 cut tread tires and pulling several thousand pounds of stubborn weight with. Therefore, it's necessary to "beef up" the engine, drivetrain, transaxle and chassis to be truly competitive and to keep parts from breaking. If you're wanting to win, you might as well build it to win!
Personally, I think it's best to convert a Cub Cadet (or any garden tractor) that's dilapidated or near to being a "piece of junk" into a pulling tractor. Because it'll be a shame to convert a nice looking, fully functional and useful mowing/utility tractor into strictly a pulling tractor. Besides, for it to be truly competitive, the entire tractor, including the engine, drivetrain, transaxle and chassis, will all need to be completely disassembled, reinforced and rebuilt/built-up from the ground up or from scratch. So why not do it with something that will need to be totally rebuilt anyway? Because if it's not rebuilt/built-up now or before the pull(s), you may be wishing it was. And don't be surprised or disappointed when (not if) changes will need to be made to the tractor so it'll be more competitive. This is part of the learning process, using the latest technology, being competitive and enjoying the sport.

When building a pulling tractor, remember - it's best to use what the winners are using - a clutch drive Cub Cadet and the biggest engine that's allowed in your class. And there's sanctioning rules with every pulling club/association regarding how a tractor should be built or set up. Not all clubs use the same rules and specifications. These rules vary from one club to another. You'll need to contact the person in charge of the club you plan to pull with and acquire a copy of their up-to-date rules and ask their pullers questions before you start to build a tractor. And while you're at the pulls, look over the other pulling tractors and ask the pullers questions regarding how to build a durable and competitive tractor.
(Cub Cadet) tractor will need 23-10.50x12 lug tires (rear), 4.10/3.50-4 (front) tires; a 10" drawbar height. Therefore, due to less stress on the rear end with the small tires and low drawbar height, can use a stock clutch assembly with the stock carrier and coarse spline axles. Weight of tractor will be either 950 or 1,000 lbs. w/driver. A stock 4,000 rpm 10hp Kohler engine can be used. (Low budget build.) And depending on power output of engine, the tractor may be able to pull in the stock 19 tooth 2nd gear. A lightweight and easy-to-start sled will also be required for this particular class of tractor.
A "V" belt will rob an engine of power simply because it "rubs" in the pulleys due to friction and that's how they grip to transmit power. If you were to place the transmission in neutral with the engine at a slow idle on a belt drive mower/garden tractor, then release the clutch pedal, you'll notice that the engine will slow down some. The tighter the belt, the slower the engine will idle. That's why V belts are noisy on some older automobiles. And that's also why auto manufacturers nowadays use a single serpentine belt to drive all the power accessories. Serpentine belts robs an engine of less power and it helps to get better fuel mileage. Direct drive Cub Cadets use no belts in the drive train. This means no power loss whatsoever.
Although sometimes a belt drive tractor will do very well in the stock class(es), they tend to lag behind in the higher horsepower class(es). But if you really like your V belt tractor and want to be a competitive puller in the higher horsepower classes, you'll have to adapt your V belt garden tractor fenders, hood, grill, etc., onto a Cub Cadet frame and drive train.
But if a belt-driven garden tractor is used for pulling (that's obviously going to be used in a stock class), the things to keep the drive belt from slipping are:
For competitive pulling, certain belt-drive transaxles are not geared "just right" to provide the proper ground speed needed to balance engine power/torque with traction (according to track conditions). One gear may be slightly too fast and another too slow. Unfortunately, there are no aftermarket gears available for most belt-drive transaxles (excluding the Cub Cadet "Original"). So to create an "in-between speed," to increase the ground speed of a belt-driven tractor, a slightly larger diameter pulley will need to be installed on the engine and/or a slightly smaller diameter pulley will need to be installed on the transaxle. To slow the tractor down or decrease the ground speed, do the opposite. A different length belt may need to be used. Actually, in the stock class, it's best to pull with an older garden tractor that have a variable speed drive. The variable speed drive works much like a manually-operated belt-drive torque converter. These tractors have a hand-operated lever that can speed up or slow down the tires when the engine is over- or under-powered according to track conditions. Cub Cadet pullers that have problems competing against these type of tractors call this lever a "cheat stick."

To prevent this from happening, fabricate and install two heavy belt guides so the belt will stay on the pulley. Make the guides L shape, from mild steel, 3/16" thick x 1" wide x whatever length they need to be. Then with the tension tight on the belt, fasten the guides to the engine block (or tractor frame) close as possible to the drive pulley with the long part of the guide spaced 1/8" from the outside edge of the belt. Position one guide over the belt where it goes onto the pulley and the other guide under the belt where it comes off the pulley. Secure them in place so they won't slip. I've done this many times with my customer's riding mowers and garden tractors drive and driven pulleys and mower deck pulleys, and if installed correctly, it works great!
To start out in pulling, an ordinary riding mower or lawn & garden tractor can be used for tractor pulling. People do it all the time. Just remember that the sled will need to be lightweight and the tractors will need a low hitch height (below the centerline of the rear axle) to prevent from breaking the transaxle and they'll need wheelie bars for safety.
