1050 Super Stock

1050 Super Stock

The smallest of the classes competing in the ITPA, these machines look much like the Cub Cadet or John Deere in your own garage. Don’t let that fool you though- these mighty  midgets run in “road gear” just like the big boys, and can be a real handful to operate. Powered by single cylinder flathead engines and on a full diet of methanol, this 1050 lb. class is entertaining and exciting. The reasonable cost of building and operating a tractor to be competitive  in this class makes it a popular choice.

1950#  MINI RODS

1900 MINI ROD

For the puller who wants a little more “zip” in his or her machine but is still budget minded, the Limited Mini Rods make sense. These tractors ride on frames fabricated from scratch, and are powered by a wide range of engines. In light of the various different approaches to horsepower in this class, the ITPA has written the rules to ensure parity for virtually everyone that competes. Injected big blocks, blown small blocks, and carbureted small block engines all operate on a playing field made level by various limits on weight, supercharger size, etc.

2000# MINI RODS

2000 MINI RODS

While these tractors are similar in appearance to the Limited Mini Rods, their horsepower output is not. With supercharged big blocks at 575 cubic inches and injected engines at 650, these tractors are a virtual one ton rocket. Awesome wheel speed, light weight and short wheel based, expect a thrill any time a “mini” hooks to the sled.

5500# ANTIQUE TRACTORS

5500 ANTIQUE TRACTORS

Open to tractors manufactured prior to 1940, this iron is old but it ain’t tired. Countless hours of tuning, tweaking and polishing make these beauties from the past look and pull like never before. Collecting and restoring “ageless iron” has never been more popular than it is today. For those who like to see the best from our father’s and grandfather’s era compete head to head in a modern plowing match, this is the class.

5500# CLASSIC TRACTORS

5500 CLASSIC TRACTORS

One might also refer this as the “nostalgia” class in ITPA pulling. Machines that were once considered huge farm tractors and are still used today turning augers and mowing pastures, get a chance to strut their stuff on the pulling circuit. Tractors built up through 1953 are eligible.

6000# SUPER STOCK TRACTORS
6000 SUPER STOCK TRACTORS

Super Stock pulling is the most direct link to the real heritage of tractor pulling. From the early days of grudge match pulling behind the barn, Super Stock has endured the test of time to evolve into the multi turbo machines of today. Unfortunately, anyone familiar to tractor pulling will tell you that the Super Stock division has been embroiled in tremendous controversy over the last few years. Diesel vs. alcohol is on everyone’s mind. Realizing the importance of both groups, and in an effort to reach a meaningful compromise, the ITPA has drawn clearly defined lines in the class by designating the 9700 lb. class as diesel only. Both the 6000 lb. and 8200 lb. classes are home to the traditional diesel “smokers” and the modern high horsepower alcohol burners. Whatever your preference, the ITPA has you covered with expertly prepared machines on both sides of the debate.

7800# PRO STOCK DIESEL TRUCKS
8000 PRO STOCK DIESEL TRUCKS

Pro Stock Diesel Trucks joined the ITPA pulling family in 2007 with results that were nothing short of impressive. With consistently good class numbers, reliable vehicles and close competition, the smoker pickups are quickly becoming a favorite with the pulling spectator. This is the only pulling division where the engine manufacturer doesn’t not have to match the sheet metal, and whether it is Dodge, Ford, or GM, Cummins is the favored power plant.

8500# LIMITED PRO STOCK
8200 LIMITED PRO STOCK

New to the ITPA for 2008, Limited Pro Sock has teh potential to become a very powerful smoker division with IH, Deere, Ford/New Holland and others all competing head to head. These machiens look similar to a Super Farm or full Pro Stock, but are limmted to 466 CID, a”3×4″ turbocharger and 8200 lbs. Look for great things from this new class in 2008 and beyond.

6350# FOUR WHEEL DRIVE TRUCKS
6200 FOUR WHEEL DRIVE TRUCKS

Chevy vs. Ford vs. Dodge lives on in the 4×4 division. Powered by mammoth 650 cubic inch engines, these highly specialized vehicles represent one of the most competitive classes within the ITPA. Competitors have refined the 4×4 truck into a thoroughbred machine that seldom breaks, hooks hard to the track, and amazes spectators with the speed and intensity they possess.

6200# TWO WHEEL DRIVE TRUCKS
6200 TWO WHEEL DRIVE TRUCKS

Supercharged wheel stands are what makes the two wheelers exciting. Body styles ranging from T-buckets to funny cars spice up the visual effect, but there is nothing “funny” about the way these smooth operators get down the track. Whether you have a flair for the exotic panel wagon or prefer an almost stock Chevy S-10, you will most likely find your favorite in the two wheel drive truck division.

5800# MODIFIED TRACTORS
5800 MODIFIED TRACTORS

Automotive and aircraft engines provide the motivation for the most powerful division in pulling. Ranging from the single engine 5800 lb. tractors to multiple blown V-8’s and twin 1700+ cubic inch Allisons in the 7500, the tremble of the earth and high RPM scream are a modified tractor fan’s delight. From show to go, nothing beats a modified tractor.

9500# PRO FARM TRACTORS
9500 PRO FARM TRACTORS

Farm stock tractors are those most closely resembling the tractors used by today’s American farmer. 20.8″ rear rubber and factory sheet metal looks convincingly stock.
Yet, one look at the trick turbos and in-line injection pumps and the trained eye knows that this no ordinary plow tractor. The 9500 lb. class is limited to 466 cubes, and the sky’s the limit in the 12,000 lb. All tractors are “on the governor” and must stay with a 3LM or T04 blower, making them dependable and closely matched. All colors are competitive.

10,000# PRO STOCK TRACTORS
10,000 PRO STOCK TRACTORS

“Smokers only please” in the Pro Stock division. Aptly named, this class is truly professional as the craftsmanship in these mighty oil burners is second to none. A single turbocharger, bigger displacement (680 C.I.D. maximum), and smaller 24.5×32 tires separate pro stocks from their cousins in the super stock division. The growl of the engine can be heard over the sound of the turbo as pro stock tractors charge down the 300′ clay surface.

9,500# LIMITED PRO STOCK
9,300 SUPER FARM TRACTORS

New to the I.T.P.A. lineup for 2000, Super Farm bridges the gap between farm stock and pro stock. Up to 640 oil burning inches are under the hood, fed fuel by a “P” series in line pump and air by a “3 in 3 out” turbo. 24.5″ rear tires hook it all to the ground. Look for another round of battle between the various brands when Super Farms head out on the circuit.

8,000# PRO STREET DIESEL TRUCKS
20,000 PRO STOCK SEMI

The heaviest of all pulling vehicles at 20,000 lbs. track ready, Pro Stock Semis are truly ground pounding beasts. Monster turbocharged power plants like Cummins, Caterpillar and Mack send these beautifully prepared rigs charging down the 300′ pulling surface under the heavy fog of diesel smoke.
