The worker used the floor jack to raise the right tires slightly, and then another worker started the engine to release the air brakes so the tires could be turned. However, the tractor moved forward and came off the jack. The worker under the tractor was pinned between the floor and the U-bolts on the leaf spring on the rear left side of the tractor. He died as a result of serious injuries.
