In a ride-on snow sled of the steerable type, a pair of support side runners are fixedly attached to fore and aft vertically oriented legs. The legs are adapted to slide up and down within hollow tubular frame members. The upper ends of the front legs of each runner are attached to one another by a non-compressible and non-extendible cable member. Similarly, the rear pair of legs are connected through a rear tubular frame. Thus, a shift of weight causing the right ski to extend downwardly from the frame causes a proportional lift or rise in the left ski such that the legs on the left ski retract into the frame. With the skis at different heights proportionate to the slope of the hill, an edging effect is created, permitting the operator to traverse the hill without sliding in much the same manner as a skier traverses a hill.

A snow sled comprising a frame and at least three runners; said frame including a pair of inverted U-shaped, hollow tubular members fixedly attached to one another by means of horizontally disposed struts or cross-braces; one of said runners being rotatably mounted and adapted to function as a steering means; two of said runners adapted to function as support and edging means; each of said two runners being fixedly attached to two or more vertically oriented legs; said legs being adapted to slidably fit within said frame; said two runners being functionally connected to one another such that, in operation, a downward movement of one runner produces a proportional upward movement of said other runner.
