A vehicle 10 includes a prime mover engine 15, a drive wheel 16, and a hydrostatic transmission 20. The prime mover engine 15 has a substantially vertical prime mover output shaft 18. The hydrostatic transmission 20 has a hydraulic pump 24 with a substantially vertical pump input shaft 28. A drive link 31 drivingly connects the pump input shaft 28 to the prime mover output shaft 18. The hydraulic motor 25 has a substantially vertical output shaft 30. An interface connector 32 establishes fluid pressure communication between the hydraulic pump and the hydraulic motor. A gear set is intermediate the hydrostatic transmission 20 and drive wheel 16. The gear set includes a vertically disposed bevel gear 41 drivingly connected to the motor output shaft 30 and a horizontally disposed bevel gear 42 drivingly connected to the drive wheel 16.

A transmission having an integrated gear and brake mechanism is disposed in a housing, the transmission having a variable drive mechanism, gear train, and an output axle engaged to the gear train. The output axle is driven by a final drive gear having an integrated drum brake within its circumference.

A variable speed transmission disposed in a housing includes a transmission input shaft and a transmission output shaft. A power take off is disposed in the housing and includes a power take off output shaft and a clutch/brake mechanism having a clutch input hub engaged to and driven by the transmission input shaft, a cage engaged to the clutch input hub, a brake stator and a brake rotor and carrier being selectively engageable with the cage and alternately selectively engageable with the brake stator. An output hub is rotatably driven by the brake rotor; and a biasing member is disposed between the cage and the brake rotor to bias the brake rotor to engagement with the brake stator.

A drive assembly is disclosed, with a variable speed transmission in a housing. A pair of clutch assemblies are engaged to a transmission output shaft, and engaged to and selectively driving a pair of axle shafts. A power take off includes a power take off output shaft and a clutch/brake mechanism. A first and a second output gears are driven by the transmission output shaft and disposed on a first and second jack shafts, respectively. A first intermediate gear is disposed on a third jack shaft and driven by the first output gear, and a second intermediate gear is disposed on a fourth jack shaft.
