There are three divisions of Model Tractor Pulling. All 4-H members start at the division one level regardless of age. For a fee the members receive a length of aluminum rectangular box and the parts needed to assemble a pulling unit. Division one pullers also learn to pull using an electric motor as a power source.
As for the tractor body itself any tractor whether comes off of a shelf at a dealer, out of a sandpile, from the toy box, or any other location the tractor doesn't have to be new, But it needs to be of 1/16 scale and have a front axle.
The 4-h puller and a parent or volunteer assemble the tractor body and the gear box under the standardized rule of eight inch wheel base and a overall length of 10.5 inches from the rear axle to front most part of the tractor (weight bracket).
New paint is allowed but chrome, decals, or paint other than stock aren't allowed in division one. Including aluminum wheels.
A project sheet and a folder featuring the members project will accompany the tractor when judged for display. This will account for 25% of the members final project score. Actual pulling in two classes; 4# and 6# will account for the other 75% of the total score for a sweepstakes award.
