WTPA Competition Classes!
Super Farm Tractors
The Super Farm Tractor class is probably the closest tractor class you will see that resembles a farm tractor. Weighing in at 9300lbs, the Super Farm Tractor produces its power on a single 3″x3″ turbo charger and a 640 cubic inch power plant to get down the track. This class is known to be one of the closest in competition as you could see the entire class finish within a couple feet from first to last.
Limited Pro Stock Tractors
The Limited Pro Stock Tractor class may look similar to the Super Farm class, but looks can be deceiving. Limited to a 4.1 turbo charger and 640 cubic inches, these 9,500lb tractors have become one of the more popular classes in the Dairyland. Whether it’s on the state level, or regional level, this class has grown rapidly over the last couple years and caught the attention of many pullers and fans!
Light Pro Stock Tractors
For many, the Light Pro Stock class many give them nostalgia of what the Pro Stock Tractor class use to be. Years later, the Light Pro Stock Tractor class has grown to a popular class on the state and regional level. With only 540 cubic inches, they need to find their power elsewhere and that answer lies in a turbo charger of any size! The way to keep these tractors from making too much power is to limit them to an 8,500lb ag-style chassis. Many like to refer to this class as the “whomp, whomp” class for the sound these tractors make while idling.
Light Limited Super Stock Tractors
A relatively new class to the WTPA, the Light Limited Super Stock Tractor class is one of the more diverse classes when it comes to brands. From John Deere, Case, Ford, and even Allis-Chalmers, there is sure to be a tractor for all fans to cheer for. These tractors weigh in at 6,250lb and are limited to a 3×4 turbo charger. Cubic inches vary depending on the setup the owner decides to run. It can’t go without mentioning that the Light Limited Super Stock Tractor class brings back the alcohol vs. diesel tractor battles, as this class allows for both fuel types, making it a fan favorite!
Light Super Stock Tractors
These high flying tractors are known for their amazing wheel speed and wild rides. Weighing in at 6,200 lbs. the Light Super Stocks are the lightest tractors the WTPA has to offer. Limited to 504 cubic inches, these tractors run on alcohol or diesel and may run up to four turbochargers! You may not believe it, but this is the WTPA’s most powerful class when it comes to horsepower! The Light Supers are growing in popularity each year and are known to be a class that brings a variety of brands to the track for competition.
Modified Mini Tractors
The Modified Mini Tractors may be small, weighing in at 2,050, but watching this class will keep you on the edge of your seats. With a 14-71 supercharger mounted on top of a maximum 575 cubic inch motor, these little hot rods are making well north of 2,500 horsepower. What makes it even more crazy are the drivers are literally straddling all that horsepower between their legs for 300′ down the track!
Two Wheel Drive Trucks
The Two Wheel Drive Truck division is a class most people closely relate to drag racing. With similar body styles of that of a funny car, these trucks are supercharged with a 14-71 supercharger pushing all the air into a motor limited to 575 cubic inches. Running on alcohol, the Two Wheel Drive Truck class need to find a way to get all the power to the track when doing some pretty amazing wheel stands! These 6,200lb machines comes in many different styles produced by mostly American-made brands that give the fans someone to cheer for.
Four Wheel Drive Trucks
Referred by many as drivers class, these carbureted behemoths are limited to 650 cubic inches on alcohol fuel. These vehicles are know as the Four Wheel Drive Trucks which you will see are mostly American-made body styles which give fans the battle of Dodge vs. Ford vs. Chevy. It takes a lot of finesse while steering and throttling these trucks down the track and it’s not uncommon to see these trucks start hopping. As most of the weight is on the nose of the truck, one small bump can cause the rear-end to unload causing the truck to bounce it’s way down the track. No matter what happens, these 6,200lb trucks will be throwing dirt backwards as it settles all four tires into the track!
2.6 Diesel 4×4 Trucks
The newest class to the WTPA, the 2.6 Diesel 4×4 Trucks is a popular class for the younger generations. Fans shout and cheer their brand loyalty as these 8,000 lb pickups are making their way down the track. All trucks run a 2.6″ turbocharger to produce the power to try and inch out the close competition. Running an OEM body and DOT tires makes this class easy to relate to a farm or work vehicle sitting in the parking lot.
