摘要： A clutch mechanism having a drive shaft operatively connected to a drive section of a working vehicle, and a driven shaft connected to a working implement such as a mower unit. The clutch mechanism includes a clutch mounted on the drive shaft to be operable between an ON state to transmit drive from the drive shaft to the driven shaft, and an OFF state to break drive transmission; a transmission shaft connected to the clutch; and a shift device connected to the clutch to be shiftable between a first position corresponding to the ON state of the clutch and a second position corresponding to the OFF state of the clutch. The shift device has a clutch control device shiftable to control the clutch, and a first helical gear axially movably mounted on the transmission shaft. The clutch mechanism further includes a second helical gear rotatable with the driven shaft and meshed with the first helical gear, and a brake for applying a braking force to the shift device when the shift device is in the second position. The first and second helical gears are shaped such that the second helical gear applies a reaction to the first helical gear to push the first helical gear toward the first position when the clutch is in the ON state to transmit the drive from the drive shaft to the driven shaft, and the second helical gear applies a force to the first helical gear to push the first helical gear toward the second position when the clutch is in the OFF state and a force is transmitted from the driven shaft.

摘要： A pickup-style work vehicle comprises a front driver's seat, a backseat, a loading floor that is located rearwardly of the backseat and that can be moved to a dumping position, a loading floor size changeover mechanism, and a backseat posture change mechanism. The loading floor size changeover mechanism changes the size of the loading floor between a first state in which a front wall portion and a front bottom portion of the loading floor are moved forwardly in a fore-and-aft direction and a second state in which the front wall portion and the front bottom portion of the loading floor are moved rearwardly in a fore-and-aft direction. The backseat posture change mechanism changes a posture of the backseat between a first posture which is a non-use state and a second posture which is a use state. The fore-and-aft dimension of the backseat in the first posture is less than a fore-and-aft dimension of the backseat in the second posture. the backseat in the first posture is located immediately forwardly of the loading floor in the first state and the backseat in the second posture is located immediately forwardly of the loading floor in the second state.

摘要： A device for attaching a working implement to the front of a running vehicle for performing work while following the ground comprises a pair of opposite inflexible links pivoted at their rear ends to the front of the vehicle. These inflexible links are movable upwardly or downwardly and each link has a front end for movably supporting the front portion of the implement about a lateral pivot. A pair of opposite suspenders are each mounted on a longitudinally intermediate portion of each link for suspending the rear portion of the implement, each of the suspenders including a rod assembly pivotally connectable to the implement's rear portion and a resilient member. The rod assembly is inserted in an upstanding state through the link and is movable axially thereof to thereby permit upward or downward movement of the implement's rear portion due to the movement of the implement about the pivot. The resilient member is provided around an upper portion of the rod assembly above the link and elastically bears against the link. A lift unit is provided between the vehicle and the links for raising or lowering the implement through the links and the suspenders. The lift unit permits upward or downward movement and sidewise tilting of the entire implement due to the pivotal movement of each of the links independent of the other link.

摘要： A pick-up style work vehicle includes a rollover protection structure (ROPS), a seat section including a forward driver's seat and a rear seat, and a rear seat posture changing mechanism for changing the rear seat in its position between a first posture where the rear seat is in a non-use condition and a second posture where the rear seat is in a use condition. A fore/aft length of the rear seat in the first posture is shorter than the fore/aft length of the rear seat in the second posture. The work vehicle also includes a partitioning member for partitioning the seat section from a space behind the seat section with the partitioning member being supported by the ROPS. The partitioning member is movable with being supported by the ROPS between a rearwardly displaced position immediately behind the rear seat and a forwardly displaced position moved forward from the rearwardly displaced position.
