A quality measurement system includes a first camera (162), a second camera (163), a display device (500), and a controller. The controller is configured or programmed to control the first camera (162) to acquire a first image that includes agricultural items and to determine, from the first image, one of the agricultural items that is suitable for measuring quality. The controller is configured or programmed to control the second camera (163) to acquire measurement data of the one of the agricultural items. The controller is configured or programmed to store estimation models for calculating at least one quality score based upon the measurement data acquired by the second camera (163) and to select one of the estimation models according to the one of the agricultural items. The controller is configured or programmed to calculate the at least one quality score of the one of the agricultural items based upon the selected one of the estimation models.

ABSTRACT OF THE DISCLOSURE A quality measurement system includes a first camera (162), a second camera (163), a display device (500), and a controller (355). The controller (355) is configured or programmed to control the first camera (162) to acquire a first image that includes a plurality of agricultural items. The controller (355) is configured or programmed to determine, from the first image, one of the plurality of agricultural items that is suitable for measuring quality. The controller (355) is configured or programmed to control the second camera (163) to acquire measurement data of the one of the plurality of agricultural items. The controller (355) is configured or programmed to calculate at least one quality score of the one of the plurality of agricultural items based upon the measurement data. The display device (500) is configured or programmed to display the at least one quality score.

Provided is a work vehicle capable of improving operability. A work vehicle (10) includes an operation panel (33) facing a driver (H), a steering post provided to extend from the operation panel (33) toward the driver (H), a display device (50) provided on the operation panel (33), and a rotation operation unit (41) provided on the operation panel (33) and operated by the driver (H).

A work machine (10) includes an openable/closable door (40) that includes a door body (41) and a hinge (42) that includes a first shaft (43), and a lock mechanism (50) that is capable of holding the openable/closable door (40) in an opened state, in which the lock mechanism (50) includes a second shaft (52), an engaging member (51) that is swingably supported by the second shaft (52), and a pin (45), in which the engaging member (51) includes a body portion (55) that has a plate shape, a shaft hole (58) that is defined in the body portion (55) and through which the second shaft (52) is inserted, and a hook portion (56) that is formed at a position separated from the shaft hole (58) in the body portion (55), the second shaft (52) revolves about the first shaft (43) according to pivot of the door body (41) around the first shaft (43), the engaging member (51) swings around the second shaft (52) according to the revolution of the second shaft (52) about the first shaft (43), and the hook portion (56) engages with the pin (45) in a state in which the door body (41) is disposed at a predetermined opened position.

A mower unit (1) includes: a mower deck (2); and a wheel unit (4), the wheel unit (4) including: a wheel body (40); and a wheel holding mechanism (5) configured to move the wheel body (40) heightwise relative to the mower deck (2) and hold the wheel body (40), the wheel holding mechanism (5) including: a holding rod (7) coupled to the wheel body (40); a boss bracket (50) including a boss section (51) through which the holding rod (7) extends in such a manner as to be movable heightwise; an operation rod (6) having an axis, slidable along the axis, and including: a locking section (62) configured to lock the holding rod (7) at any of a plurality of positions; and an unlocking section (63) adjacent to the locking section along the axis and configured to permit the holding rod (7) to move heightwise; and an elastic member (65) configured to urge the operation rod (6) into the locking state and hold the operation rod (6) in the locking state.

A working vehicle includes a roof unit having an internal space partitioned by an inner roof and an outer roof, an air conditioning unit that is housed in the internal space and air-conditions the interior of a cabin, a filter device capable of removing a removal target contained in introduced external air, a filter device capable of removing a removal target contained in introduced external air and being different from the first filter device, and a switching mechanism capable of switching among a first introduction state in which the air purified by the filter device is introduced into the air conditioning unit, a second introduction state in which the air purified by the filter device is introduced into the air conditioning unit, and an inside air circulation state in which air from the interior of the cabin is introduced into the air conditioning unit.

A work vehicle includes a driving force transmission shaft that is disposed with an axis oriented in a front-rear direction and to which driving force of an engine is transmitted, a transmission shaft that is disposed with an axis oriented in a left-right direction and that transmits driving force from the driving force transmission shaft to left and right front wheels, a front axle case that houses the transmission shaft, and a steering cylinder that is capable of changing a turning angle of the front wheels and is provided on the front axle case so as to be positioned above the transmission shaft. (Fig. 1)

A travel control system includes a positioning device to output position data of a work vehicle, and a controller configured or programmed to control operation of the work vehicle, operate in a recording mode to store path data concerning a path traveled by the work vehicle including waypoint data acquired based on the position data while the work vehicle is traveling, operate in a reproducing mode to control the operation of the work vehicle while causing the work vehicle to travel via self-driving based on the path data, classify, based on the path data, the path into a first section having a curvature equal to or less than a threshold and a second section having a curvature greater than the threshold, and vary a control method for operation of the work vehicle in the reproducing mode between the first and second sections.

A working vehicle includes a roof unit having an internal space partitioned by an inner roof and an outer roof, a filter device that is housed in the internal space and is capable of removing a removal target contained in introduced external air, a first seal member that seals at least a space in which the filter device is disposed, and a second seal member that seals at least a space in which a second guide member connected to the filter device is disposed.
