Abstract
A snowmobile construction wherein the components are laid out so as to improve the center of gravity of the snowmobile and position the major components so that they will exert a large portion of their weight on the drive belt. The snowmobile includes a built-up frame assembly that defines a cradle in which the engine is positioned and which drives the drive belt through a pair of transmissions. One of these transmissions is disposed within the frame assembly and in a casing carried by an opening in one side of the frame assembly. The snowmobile is steered by a steering shaft that extends across the top of the engine and through a space between the exhaust manifold of the engine and the engine so as to provide a compact assembly. The positioning of the transmission inboard of the frame permits the use of a forwardly positioned seat with foot rests disposed outwardly of the transmission but closely adjacent the sides of the frame.
