ABSTRACT:
An improved drive structure is provided for use between a lawn and garden type vehicle and a vertically adjustable belt driven, belly-mounted implement such as a rotary mower. The structure is usable with a standard length engine crankshaft which is mountable to project below the vehicle chassis and power the belt driven mower. It includes a stub shaft extension that is adapted to carry an electric clutch as well as a pulley for driving a belt entrained around the mower spindle pulleys. The extension permits positive power transmission to the drive pulley and also allows for it to be mounted substantially horizontal with the implement pulleys as they are shifted vertically in response to height of cut adjustments and/or variation in terrain. The extension further eliminates the need for jacksheave power relay arrangements commonly used to reduce the angles of drive belt entry and exit into and out of drive and driven pulleys.
