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 work vehicle configured to carry out a utility work while traveling autonomously includes an implement unit mounted on a vehicle body for carrying out the work, a work subject information acquisition section for accruing work subject information indicative of information on a work subject, a load calculation section for calculating a load of the work based on the work subject information, a storage section for storing driving conditions of the implement unit in advance, and a driving section configured to retrieve a driving condition stored in the storage section according to the load calculated by the load calculation section and to drive the implement unit based on the retrieved driving condition.

A work area determination system for an autonomous traveling work machine which is controlled autonomously based on self machine position information indicative of a self machine position, the work area determination system including an operation terminal capable of determining a work area. The operation terminal includes a positioning device for acquiring terminal position information indicative of a position of the operation terminal, a work area determination section that determines the work area based on the terminal position information, and a work area information outputting section for outputting work area information which is information relating to the determined work area.

Work area determination system for autonomous traveling work machine, autonomous traveling work machine and work area determination program

A work vehicle including: a vehicle body frame; a prime mover part located on a front or rear part of the vehicle body frame; a bonnet configured to open and close by swinging, and covering the prime mover part; and an assist unit configured to assist the bonnet to operate to open. A lateral end portion of the vehicle body frame is provided with a first linkage part with which the assist unit is linked. A lateral end portion of a lower end part of the bonnet, which is located closer to an end cover than the first linkage part is, is provided with a second linkage part with which the assist unit is linked. The assist unit is provided with an expansion/contraction mechanism biased so as to expand, and is located laterally outside the prime mover part and spans the first linkage part and the second linkage part.

A tractor includes an engine that is mounted on a vehicle body frame, a hood that houses the engine and is configured to pivot about a front pivot in a top-bottom direction between a closed position at which the hood covers the engine, and an open position at which the hood exposes the engine, a mounting rubber that is provided between the engine and the vehicle body frame to support the engine in an anti-vibration manner, and a hood stay that supports the hood such that the hood is pivotable up/down about the front pivot. The hood stay includes an abutting-target portion against which the engine can abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body.

Provided is a work vehicle having a rollover protection structure (ROPS) around a driver's seat which is switchable between a front seating posture and a rear seating posture. A locking mechanism locks the driver's seat to the rear seating posture. The locking mechanism includes a hook provided on the driver's seat side, a hook rod disposed between a left strut and a right strut and engageable with the hook when the driver's seat is switched to the rear seating posture, and a rod bracket for supporting the hook rod. The rod bracket is provided separately from the left strut and the right strut.

A work vehicle includes a vehicle body frame, a protection frame extending upwards from the vehicle body frame, the protection frame including left and right strut members and an arch member extending between and detachable from the left and right strut members, a support frame provided in the vehicle body frame and configured to support the protection frame to the vehicle body frame, the support frame including a pair of left and right pipe-like supporting portions, each supporting portion being provided under a laterally outward tilted orientation with an upper portion of the supporting member being positioned on more laterally outer side of a vehicle body and being configured to removably support the strut member, and a connection tool configured to non-removably connect the left and right strut members to the left and right supporting portions.

A mower unit is detachably mounted between front wheels and rear wheels of a mid-mount grass mower. The mower unit includes a blade cover having a top plate and a side plate extending from a circumferential edge of the top plate, a pair of right and left ride-over deck units provided on the top plate. Each ride-over deck unit includes a support deck fixed to an upper face of the top plate, a wheel guide member movable between a home position for storage in the support deck and a bridging position for bridging between the support deck and a ground surface, and a tethering member for tethering the support deck with the wheel guide member.
