A novel solution for converting a snowmobile for use as a four-wheeled vehicle for transport or recreation when there is no snow cover on the ground. The present invention consists of an integrated chassis frame to which four wheels are attached. The front wheels are pivotally attached to the frame and interconnected by a steering linkage. The rear wheels are attached to an axle that is rotated by a chain drive linkage that is in turn driven by an arrangement of frictionally connected rubber wheels. The present invention is employed by first driving a snowmobile onto the top of the chassis. The skis at the front of the snowmobile engage into channels formed at the front of the chassis that are pivotally connected to the chassis and integrally connected to the steering linkage for translating the steering action of the snowmobile to the carts front tires. The drive action generated by the snowmobile track is frictionally transferred into the rubber tire arrangement and thereby into the rear axle to provide the power required to rotate the rear tires and drive the vehicle.

1. A device for converting a snowmobile to wheeled use, said snowmobile comprising a drive track and at least one ski for steering, said device comprising:a frame having front and rear ends; a front wheel assembly rotatably supporting said front end of said frame, said front wheel assembly having a ski receptacle receiving said at least one ski of said snowmobile, said front wheel assembly being pivotally mounted to said frame to provide steering whereby steering movement of said ski causes a corresponding steering movement of said front wheel assembly; a rear wheel assembly rotatably supporting said rear of said frame; and a drive transfer assembly coupled to said rear wheel assembly, said drive transfer assembly including a drive member engaged with said drive track of said snowmobile, whereby rotation of said drive track of said snowmobile causes a corresponding rotation of said drive member and further corresponding rotation of said rear wheel assembly.
