摘要： A transaxle apparatus is constructed so that left and right axles, two hydrostatic transmissions (HSTs), one for driving a vehicle and the other for steering it, and a differential unit for differentially connecting said axles with each other are together contained in a housing. The driving HST is disposed so that its hydraulic pump and motor are aligned along either a left or right side of the housing. The steering HST is disposed so that its hydraulic pump and motor are aligned along either a front or rear side of the housing. The differential unit is laterally opposite to the driving HST. Either the left or right axle crosses the driving HST between its hydraulic pump and motor. The two HSTs are provided with one or two flat center sections disposed in the housing. The cylinder blocks of the hydraulic pumps and motors of the two HSTs are mounted on either a top or bottom surface of the center section or sections. Power transmission mechanisms for transmitting output power from the hydraulic motors of the two HSTs into the differential unit are disposed on an opposite side of the center section(s) as the cylinder blocks. A charge pump may be attached onto the center section, and a conduit for sending fluid discharged from the charged pump into one or both HSTs may be partly extended outside the housing so as to be cooled by the atmosphere.

摘要： A power take-off casing (47) including therein a rear-PTO shaft (12) and a transmission mechanism (50) therefor is mounted on an outer surface of a rear wall (3c) of the transmission casing (3) disposed between left and right rear wheels (4) which constitute drive wheels for a working vehicle, and a gear (52) constituting an input member of the transmission mechanism is operatively connected to a drive mechanism (46) for a mid-PTO shaft (9) which extends forwardly from the inside of transmission casing through a front wall (3a) thereof. A clutch (60) for selectively cutting-off the drive of the rear-PTO shaft is provided preferably such that it couples the gear selectively to a drive gear (58) which is rotatably mounted on the mid-PTO shaft. In a working vehicle in which a transmission casing is disposed between left and right front wheels constituting the drive wheels for the vehicle, a power take-off casing having a front-PTO shaft is mounted on an outer surface of a front wall of the transmission casing.

摘要： In a transmission (10) comprising a casing (12), a vertical input shaft (13) having an upper end which extends upwardly of the casing and carries an input pulley (14), and a horizontal wheel axle (18) for driving a pair of mower-drive wheels (3), the input shaft intersects the wheel axle at a location in close proximity to the axle and is supported by top and bottom walls (12a, 12b) of the casing. The vertical shaft and horizontal axle are connected by a hypoid gearing (26) having a hypoid pinion (27) mounted on the shaft and a larger hypoid gear (29) mounted on the axle. The transmission has a compact configuration while the input shaft is supported in a stable manner and while the transmission efficiency between the shaft and axle is kept high. Preferably, the larger hypoid gear is rotatably mounted on the axle and a frictional clutch (32) is disposed between the gear and axle.
