- a) a pair of parallel spaced apart skis;
- b) a plurality of blade-type cleats rearwardly facing along the bottom surface of each of said skis, which will dig into snow during a rearward movement of said skis;
- c) an H-shaped frame having a long center member and front and rear short end members affixed between and elevated above said skis;
- d) a seat mounted rearwardly on said long center member of said frame so that a person being the operator of said sled can sit thereupon;
- e) a foot rest mounted forwardly below said front short end member on said frame to support the feet of the operator;
- and
- f) a pair of drive mechanisms, each drive mechanism includes a pair of thrust levers mounted to a pivot rod having a fixed pivot axis for pivotal movement relative to the skis, each pair of thrust levers straddling a respective one of said pair of skis between said short end members and having upper and lower ends, a handle affixed to and extending between the upper ends of each pair of thrust levers, and a pair of hook spurs pivotally mounted to respective lower ends of each pair of thrust levers, each hook spur being mounted to face rearwardly and having a stop member for preventing pivotal movement of said hook spur relative to said thrust lever when said handles are pushed forwardly by the operator for propelling the sled in a forward direction.
