ABSTRACT:
A tractor pull sled including a weighted pan movably supported on a frame intermediate the forward and rearward ends. The frame is supported by a plurality of ground engaging wheels, at least one of which is coupled to and actuates a pan support assembly which transfers the weight of the pan to the ground at a rate which is a function of the distance of forward travel of the sled. The pan support assembly also functions to transfer the weight of the frame onto the pan after the full weight of the pan has been applied to the ground.
