ABSTRACT:
A snowmobile lift comprising a base frame and a secondary frame is provided. The secondary frame is attached to the base frame by pivot members. The pivot members are used to move the secondary frame between a raised position and a lowered position with respect to the base frame. A handle is rotatably attached to the base frame and at least one raising arm is connected between the handle and the secondary frame. The handle is movable between a first position corresponding to the lowered position of the secondary frame and a second position corresponding to the raised position of the secondary frame. When the handle is moved from its first position to its second position, the raising arms pull said secondary frame into its raised position about the pivot members. A locking bar is provided to secure the secondary frame in the raised position.
