Abstract
The present invention is directed to a discrete drive system for a skid steer loader comprising a pair of independent transmission cases interconnected by a plate member at a spaced relationship. The transmission cases enclose chain and sprocket drives for the loader and have the axle housings outwardly extending from the outer side walls thereof. A pair of gear reduction means are mounted on the inner side walls of the transmission cases to provide a drive power to the front and rear stub axles at reduced speeds. The gear reduction means incorporates an improved brake device including a circular drum secured to the reduction gear, a flexible band wound around the drum and an eccentric cam shaft for actuation of the brake device. Coupled to the gear reduction means are a pair of hydrostatic motors having output shaft extending into the outer casings of the reduction means. Each of the output shafts has a tapering shape and terminates at its threaded end to facilitate the mounting of the pinion gear.
