Abstract
A snowmobile support dolly has a pair of two-wheeled H-frame ski dollies and a caster wheeled H-frame track dolly for supporting the steering skis and drive track, respectively, of a snowmobile. The ski dollies clamp to the bottom of the steering skis, and the track dolly has spaced transverse members which hold it in place between the transverse ribs of the track, so that the snowmobile is easily wheeled about.
Claims1
A single-wheeled dolly adapted to support a snowmobile having a longitudinally extending, endless drive track including a plurality of transverse traction ribs, said dolly comprising:
- a pair of spaced apart transverse supports having a length generally similar to the width of said track;
- at least one elongated member interconnecting said transverse supports;
- and only one wheel, said wheel comprising a caster wheel pivotally mounted to said elongated member intermediate said transverse members, said dolly adapted to support said track with said transverse supports extending parallel to said ribs, whereby said dolly is prevented from sliding longitudinally along said track by engagement of one of said ribs with one of said transverse supports.
