The first tractor pull in Tennessee was held in Obion County (1970) in the front yard of a residence 39 years ago before moving to the then newly-built Obion County Fairgrounds. It was there the county served as host for several years to one of the South's largest nationally sanctioned events.

This year there will be 6 Cellular Source Sanctioned Classes and 1 Local Stock 4 Wheel Drive Class! Be sure to be there and check out the 6,000 pound super stock tractors, 6,200 pound super modified two-wheel drive, 6,200 pound super modified four-wheel drive, 6,200 pound pro stock four-wheel drive, 6,200 pound pro street four-wheel drive and a Hot Farm tractor class Many pull fans have expressed that they'd like to see more super stock tractors, so we have added the 6,000 super stock class and a Super Farm class" Wood said. Come see the black smoke roll."

Super stocks come the closest to tractors seen on the farm, but they have 10-20 times the factory rated horsepower. With up to four staged turbo chargers boosting manifold pressure about 200 pounds, these seemingly docile machines become turbo charged dynamite. Six cylinder diesels that left the factory rated 120 horsepower are pushed to make 1,800 or more horsepower.

Powered by the strongest supercharged V-8s in pulling, two-wheel drive trucks seem to launch off of the starting line. Often holding a wheel stand for the entire run. The advent of funny car bodies on many of the vehicles has made this division very appealing to the fans. These vehicles are for competition only and produce upward of 1,900 horsepower.

Four-wheel drive trucks are the only pulling vehicles that are allowed to use more than two-wheels under power, Four wheel drive trucks motors make around 1,600 Horsepower by sending power through all four-wheels, making this the most efficient pulling vehicle.

Modified tractors originated in the 1960's when pullers started mounting automobile and airplane engines in tractor frames. The iron competition in this division represents the wildest and most powerful show in pulling. Alcohol is the most exotic fuel allowed in pulling and modifies May have as many as seven blown alcohol V-8 engines. The single airplane engines are being supplemented by the multiple turbine engines that can produce over 12,000 horsepower.

Wood has been promoting tractor pulls and monster truck shows for 32 years in 32 states and Canada. "The last 2 to 14 years we have devoted most of our time to our cellular, Internet, paging, two-way radio and tower erection business." Wood said. "We still promote 2 or 3 pulls a year and help oversee the Obion County Fair Pull" as this is where it all Started in the South 39 years ago.
