Abstract: A braking feature is provided that can resist gliding board runaway, i.e., uncontrolled gliding without a rider, or other movement of a gliding board, e.g., a gliding device having no foot bindings. The braking feature may always be active to resist gliding board movement, and/or resist movement only when a rider is not supported on the gliding device. Activation of a braking feature may be delayed. The braking feature may be controlled based on a force urging a bottom surface of the gliding device into contact with the gliding surface, e.g., the braking feature may be deactivated if the weight of a rider is supported on the gliding device. A force that deactivates a braking feature may be made adjustable, e.g., to accommodate riders of different weights or to provide different braking feature responses.

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.
