摘要： A working vehicle having a main transaxle casing supporting a first PTO shaft and a center-pivot transaxle casing supporting second PTO shaft, improved in a transmission system for the second PTO shaft. Particularly, the center-pivot transaxle casing is provided at the portion thereof lower than its pivot with the second PTO shaft. The output power of the first PTO shaft is transmitted to the second PTO shaft by a propeller shaft and universal joints. If a working machine to be driven by the first PTO shaft is disposed between the both transaxle casings, the output power of the first PTO shaft is transmitted to the working machine, and afterward to the second PTO shaft.

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 for a working vehicle, a PTO input shaft is located with its rotational axis extending in a vehicle lengthwise direction substantially at a widthwise center of a transmission case along a vehicle width direction. A running power input shaft is located with its rotational axis extending in the vehicle lengthwise direction substantially at the same position as that of the PTO input shaft along the vehicle width direction and at a lower side of the PTO input shaft. The transmission case provides an accommodation space for accommodating a differential gear unit, which space is displaced to a first lateral side of the vehicle along the vehicle width direction. A running power transmission shaft is located on the front side of the space with its axis extending in the vehicle lengthwise direction, and the running power input shaft, the running power transmission shaft and the differential gear unit are interlocked to each other via a running power gear train.

The pair of ring gears are rotatably disposed around the respective carriers so as to slidably abut at their inner peripheral surfaces against outer peripheral surfaces of the respective carriers. Each of the ring gears is extended between the sun gear and each of the carriers disposed in the ring gear so as to be inner peripherally formed into an internal gear. Each of the carriers is integrally provided with a plurality of projections projecting toward the center gear between the sun gear and the internal gear. The planet gears are rotatably disposed around the respective projections of the carrier so as to engage with the sun gear and the internal gear. The projection is preferably formed of the carrier. Tips of teeth of the internal gear are extended toward the axis of the axle further than the inner peripheral surface of the ring gear slidably abutting against the outer peripheral surface of the carrier.
