Title: Unitary frame and engine support for snowmobile

Abstract: A frame construction for snowmobiles which utilizes perimeter frame members for carrying the front cross axle for the front ski spindles. The perimeter frame members are attached to and reinforced with respect to the tunnel that houses the drive track to provide a rigid structure that permits a wide spacing at the front of the tunnel for placing an engine and torque converter in a low position, to aid in lowering the center of gravity of the snowmobile, without complex mounting and frame members.
