Abstract: An operating system is formed in which an engagement shaft supported on an end portion of a brake piston is inserted through an engagement hole portion of a balance member; an operation wire is connected to the balance member via a coupling pin; and brake operating arms of rear wheel brake mechanisms are operated by a pair of arm portions of the balance member. A broad area is formed in the engagement hole portion in a manner allowing the balance member to swing about the coupling pin when the operation wire is pulled.

Abstract: A suspension arm unit for vehicle includes: a pair of profile beams each having a U-shaped cross section with an opening oriented in a horizontal direction and including: a base end part formed on one end side of the profile beam and vertically swingably supported on a vehicle body side about an axis extending in a front-rear direction; and a distal end part formed on the other end side, to which a knuckle arm unit of a wheel is attached. The pair of the profile beams are arranged in the front-rear direction so that the openings face each other in the front-rear direction and a gap between the profile beams becomes larger from the distal end part to the base end part, and the pair of the profile beams are connected to each other at the distal end part and to the knuckle arm unit through a rotary joint.

Abstract: A work vehicle includes a hydrostatic continuously variable speed-change device, a gear type multiple-stage speed-change device disposed downstream of the hydrostatic continuously variable speed-change device with respect to a direction in which power is transmitted, first and second oil passages, a bypass oil passage communicating the first and second oil passages with each other, a valve mechanism for opening and closing the bypass oil passage, and a manual operating member provided in a driving section for opening and closing the valve mechanism.

Abstract: A cab includes a cab frame forming the cab, an outer roof configured to cover the cab frame from above and to be fastened to the cab frame from above, a seal mount protruding downwardly from an edge of the outer roof, and a seal material including a body portion having a recess for receiving the seal mount. The periphery of the body portion of the seal material has a seal lip for contacting the cab frame for sealing, and a drain groove for draining water entering between the seal material and the cab frame.

Abstract: An operator's station structure for a work vehicle having a motor section, comprising: a seat that is disposed on the operator's station for a work vehicle and has a moveable seat part; and a removable storage box that is disposed below the seat, that has an upwardly opening shape, and that has an interior accessible by moving the seat part.

Abstract: A work vehicle includes: a hydrostatic continuously variable speed-change device; a gear type multiple-stage speed-change device disposed downstream of the hydrostatic continuously variable speed-change device with respect to a direction in which power is transmitted; first and second oil passages interconnecting between a hydraulic pump and a hydraulic motor in the hydrostatic continuously variable speed-change device; a bypass oil passage communicating the first and second oil passages with each other; a valve mechanism for opening and closing the bypass oil passage; and a manual operating member provided in a driving section for opening and closing the valve mechanism.

Abstract: An interlock circuit for a working vehicle having a vehicle body, a working implement attached to the vehicle body, a clutch mechanism for connecting and disconnecting power to the working implement, and a shifting device for determining a traveling direction of the vehicle body. The interlock circuit has a check function to check a backward operational run in which the vehicle body travels backward with the clutch mechanism engaged, and a release function to permit a backward operational run by canceling the check function. The check function checks the backward operational run based on a signal indicating an on/off state of the clutch mechanism and a signal indicating a traveling direction of the vehicle body determined by the shifting device. The release function maintains the check function off continuously by operating a release switch when the clutch mechanism is engaged, and the signal indicating a traveling direction of the vehicle body indicates forward or neutral.

Abstract: A mower with a grass catcher (10) for collecting grass clippings transmitted from a mower unit. The grass catcher has an inlet opening (12) in a front position thereof, and an outlet opening (13) and an openable lid (14) in a rear position. The grass catcher (10) is connected to the rear end of a vehicle body to be supported in a suspended state by a grass catcher support unit (100). The support unit includes mounting posts (9) attached to the rear end of the vehicle body and extending upward, and a support link mechanism (20) for interconnecting upper regions of the mounting posts and lower rearward regions of the grass catcher, and for switching the grass catcher between a grass clippings collecting posture with the inlet opening directed forwardly of the vehicle body, and a raised dumping posture with the outlet opening directed downward. The support link mechanism performs a switching process for switching the grass catcher from the grass clippings collecting posture to the raised dumping posture.
