A work vehicle comprising: a drive wheel unit that is provided in a vehicle body and is configured to be driven by a travel drive mechanism; a work unit that is provided in the vehicle body and is configured to perform work on a work target; a battery provided in the vehicle body; a motor that is configured to receive electric power from the battery and drive the work unit; an inclination sensor configured to detect an inclination of the vehicle body relative to a horizontal plane; and a first captured image acquisition unit configured to acquire a captured image that shows surroundings of the vehicle body when the work is being performed.

Work vehicle and base station

A work vehicle that performs an operation while traveling autonomously includes: a base frame configured to support a wheel; a unit frame configured to support an operation unit that performs the operation; a link frame capable of changing a relative height of the unit frame with respect to the base frame, the link frame spanning between the base frame and the unit frame; and a setting unit configured to set an operating height of the operation unit with respect to a working surface of a working field in which the operation is performed, in accordance with operation information indicating an operation target to be subjected to the operation.

Work vehicle

A management system for a work vehicle configured to carry out a utility work while traveling autonomously includes a work field information acquisition section for acquiring work field information indicative of information relating to a work field where the work is to be carried out, a route information acquisition section for acquiring route information indicative of a traveling route along which the vehicle has traveled, a consumed electric power information acquisition section for acquiring electric power information indicative of consumed electric power, a tilt angle information acquisition section for acquiring tilt angle information indicative of a tilt angle of the work field relative to the horizontal plane, and a calculation section for calculating a cost required for the work, based on the work field information, the route information, the electric power information and the tilt angle information.

Management system and management method

A work area determination system for an autonomous traveling work vehicle includes a photographing device for photographing a predetermined area including a work area and acquiring a photographic image thereof, a positioning device for obtaining position information indicative of a position at which the photographic image has been acquired, a map generation section for generating a map based on the photographic image and the position information, a displaying section for displaying the map, and a work area determination section for determining the work area in which the autonomous traveling work vehicle is to work, based on an area designation for the map displayed in the displaying section.

A control panel unit has a control lever operable by a driver seated at a driver's seat of a utility vehicle. The panel unit includes a base panel which covers the control lever except for its control grip area and a guide slot defined in the base panel along an operational displacement of the control lever. The panel unit further includes an inclined panel portion inclined by a predetermined angle relative to the base panel so as to orient its surface toward the driver and extending adjacent and along the length of the guide slot. A display face is formed in the surface of the inclined panel portion and configured for displaying operational positions of the lever.

Tractor

Agricultural tractor

A tractor with a cab disposed rearwardly of a hood, the cab being mounted on a tractor body (T) including a body forming unit, the cab including a bottom wall defining left and right footrests. The cab has a total length larger than a total height thereof. The cab is arranged to have the footrests substantially level with a lower end of the body forming unit. The cab has an intermediate height level (x) lower than a height level of the hood.

A dirigible drive wheel assembly includes a transmitting and steering shaft extending approximately vertically, with an axis thereof inclined, for drivably connecting an axle of a wheel to a transmission shaft, a first driving gear disposed in a lower end region of the transmitting and steering shaft, a first driven gear mounted on the axle and meshed with the first driving gear, a second driven gear disposed in an upper end region of the transmitting and steering shaft, a second driving gear mounted on the transmission shaft and meshed with the second driven gear, a second gear case for covering the second driving gear and the second driven gear, and a first gear case for covering the first driven gear and the first driving gear. A first bearing is disposed between the first gear case and a lower end of the second gear case. Through the first bearing the lower end of the second gear case is rotatably supported by the first gear case. An arm extends from the first gear case for holding an upper end of the second gear case to be rotatable about the axis. A second bearing and a third bearing are arranged at opposite sides of the first driven gear, through which the first gear case is rotatably supported by the axle. The third bearing is located below the first bearing.
