An internal combustion engine having a V-type configuration with a camshaft disposed in the valley of the V and driven by an intermediate shaft that is offset to one side of the engine in the area of stagger between the cylinder banks. A gear train drives the intermediate shaft from the crankshaft and the camshaft from the intermediate shaft and provides a total gear reduction of one-half to one so that the camshaft rotates at one-half crankshaft speed. The engine is employed to operate a garden tractor having a lawn mower attachment.
