Abstract
A drive apparatus driven by a prime mover that has a prime mover output shaft is disclosed. The drive apparatus has a housing and a power take off. The power take off is driven by the prime mover output shaft and selectively drives a power take off output shaft. The drive apparatus further has a variable speed transmission disposed within the housing. The variable speed transmission drives a transmission output shaft, which in turn drives a first clutch mechanism and a second clutch mechanism. A first drive axle is engaged to and selectively driven by the first clutch mechanism and a second drive axle is engaged to and selectively driven by the second clutch mechanism.
Claims16
A drive apparatus comprising:
- a housing;
- a power take off disposed in the housing and driven by an input shaft and selectively driving a power take off output shaft;
- a variable speed transmission disposed within the housing and driven by the input shaft;
- a transmission output shaft driven by the variable speed transmission, and drivingly engaged to a first clutch mechanism disposed in the housing and a second clutch mechanism disposed in the housing, wherein the power take off output shaft is coaxial with the transmission output shaft;
- and
- a first drive axle engaged to the first clutch mechanism and a second drive axle engaged to the second clutch mechanism, whereby the first drive axle may be operated independently of the second drive axle.
