The tractors are divided into classes depending
on their weight and each unit is weighed prior to each event.
Some tractors pull in different classes by adding weights in
carefully chosen positions which will transfer the maximum weight
upon the rear wheels while allowing just enough weight on the
front tires to be able to steer down the marked course. Straying
outside the marked course disqualifies the contestant.
The objective being to tow a heavy sled
the distance of the course. The weight of the sled is gradually
transferred to the tractor as it progresses down the course until
the tractor either stalls or looses traction.
