  • Patent number: 10625795
    Abstract: It is contemplated to arrange a plurality of operational levers without inviting complications of the arrangements or enlargement of the vehicle body, intensively for better operability between the driver's seat and one of the right and left rear fenders. In a riding work vehicle, a plurality of operational levers 25, 26 are disposed adjacent on the right and left sides between a driver's seat and one of right and left rear fenders 7. Of the plurality of operational levers 25, 26, an inner operational lever 25 disposed on the side of the driver's seat is displaceable in a front-rear direction of a vehicle body.

  • Patent number: 6986295
    Abstract: A transmission for a work vehicle having PTO function is disclosed. The transmission includes a first transmission shaft for receiving engine power through a PTO power train, a second transmission shaft for receiving, the engine power through a traveling power train, the second transmission shaft being coupled to a rear differential mechanism, a third transmission shaft coupled to a rear PTO, a fourth transmission shaft for receiving force from the second transmission shaft, a first gear transmission mechanism for transmitting the force from the first transmission shaft to the third transmission shaft. The first gear transmission mechanism has an input gear mounted on the first transmission shaft, an output gear mounted on the third transmission shaft and a relay gear loosely mounted on the second transmission shaft for transmitting the force from the input gear to the output gear.

  • Patent number: 6889569
    Abstract: A change speed apparatus for a working vehicle includes a first shaft for receiving driving torque from an engine, a second shaft for transmitting the driving torque to a rear wheel differential, a change speed mechanism for changing speed of the driving torque received from the first shaft and transmits the driving torque to the second shaft, and a shift lever for selectively switching the change speed mechanism. The change speed mechanism has a high forward speed stage, a low forward speed stage, a backward drive stage, and a neutral stage. The shift lever is movable along a transverse control path for the neutral stage, a first longitudinal control path for the high forward speed stage, a second longitudinal control path for the low forward speed stage, and a third longitudinal control path for the backward drive stage.
