John Lynch knows how to get a motor running, which is just what the Rainbow resident will be doing on Saturday in the Somervell County Expo Center when the Texas Truck and Tractor Pulling Association (TTTPA) hosts its Glen Rose Pull.

Lynch began pulling tractors three years ago. His love for the machines stems from a life spent in rural areas.

“I’ve farmed all my life,” Lynch said. “They finally started (tractor pulls) back up.”

Lynch dedicated copious amounts of time to building two tractors the first two years he joined the TTTPA, both of which will be at the Glen Rose Pull. However, last year he decided to move from tractors to trucks.

The truck, named Zero Tolerance, is a 572 Chevrolet with a 1471 blower. The engine runs on pure alcohol, one of three acceptable fuels in the TTTPA. Zero Tolerance is also the 2005 Outlaw Pulling Association Champion in its class and is currently ranked in 1st place in the TTTPA with 225.50 points in the Super Modified 2WD class.

Running on 2,000 horsepower at 160 miles per hour, Zero Tolerance is a heck of machine.

“It’s basically the same set up that is in a top fuel racer, except we don’t run nitromethane, we run straight alcohol,” Lynch said.

While the vehicles are powerful and fast, Lynch said the pulls are really a “weight game.”

The TTTPA divides vehicles by weight class, which include limited modified, econo rod, pro modified and hot farm tractor classes and pro stock four-wheel drive, 4x4 diesel and super modified two-wheel drive trucks. Each class pulls a sled, which can range in weight from 40,000 to 200,000 pounds. Lynch explained that there is a power to weight ratio, which transfers all the power to the rear of the vehicle, often resulting in the front two wheels of the vehicle coming off of the ground.

“(It’s) pretty close to drag racing,” he said. “They’ve got the weight in the sled down to an art.”

The vehicles travel a short 300 feet before the weight of the sled typically catches up and stops them. During that distance, Lynch said his truck will typically burn 10 gallons of alcohol fuel, sometimes up to 16 gallons. Kill cables are attached to the vehicles to prevent an accident in the event that one gets loose from the sled.

While the adrenaline and thrill of the high-speed sport get Lynch’s blood running, he said his favorite aspect is actually meeting other drivers.

“It’s a fun motorsport,” he said. “All the guys that go are real friendly.”

Lynch said he owes a special thank you to his close friends that make it possible for him to continue pulling, including his father and crew chief Billy Lynch, his machinist Pete Riola and his “trigger man” Roy Mosely.

The Glen Rose Pull, sponsored by the Glen Rose Antique Tractor Club, will have approximately 45 pullers and the show is estimated to run for two hours. The pull will begin at 7:30 p.m. at the Somervell County Expo Center, with a Pit Party from 6:30-7:30 p.m. Admission is $10 for adults and children 10 and under get in free. All tickets come with a pair of earplugs.
