To stably and safely perform automatic steering during rearward travel of a working vehicle, the working vehicle includes a vehicle body to be manually steered with a steering wheel or automatically steered to travel forward or rearward, a prime mover on the vehicle body, a working implement supported on the vehicle body, a power take-off (PTO) shaft to transmit power from the prime mover to the working implement, and a controller to control automatic steering of the vehicle body and driving of the PTO shaft. The controller is configured or programmed to allow the automatic steering during rearward travel of the vehicle body when the PTO shaft is in a stopped state, and prohibit the automatic steering during rearward travel of the vehicle body when the PTO shaft is in a driven state.

Working vehicle

A working vehicle includes a vehicle body to travel either by manual steering with a steering wheel or by automatic steering with the steering wheel, a reference registration controller configured or programmed to register a traveling reference line based on a position of the vehicle body caused to travel by the manual steering, a traveling line setter configured or programmed to set, based on the traveling reference line, scheduled traveling lines for traveling using the automatic steering, and an automatic steering controller to control the automatic steering based on the scheduled traveling lines. The traveling line setter is configured or programmed to change an adjacency width between the scheduled traveling lines adjoining each other among the plurality of scheduled traveling lines.

Working vehicle capable of setting scheduled traveling line for traveling using automatic steering

A working vehicle includes an inertia detector to measure inertia information of a vehicle body, a rear axle supporting a rear wheel, and a transmission case rotatably supporting the rear wheel. The inertia detector overlaps with at least a portion of the transmission case in a plan view and is capable of accurately measuring inertia information when a vehicle body changes attitude.

Working vehicle and tractor

A work vehicle is provided with a body, a driver section and an air conditioner, and the air conditioner is supported by the body and located on a side of the body.

Work vehicle

A working vehicle includes a steering handle, a vehicle body to travel with either manual steering by the steering handle or automatic steering of the steering handle based on a traveling reference line, and a display including a line orientation display portion to indicate an orientation of the traveling reference line, and a vehicle orientation display portion to indicate an orientation of the vehicle body.

A working vehicle includes a vehicle body capable of traveling either by either manual steering with a steering wheel or by automatic steering with the steering wheel, a reference registration controller configured or programmed to register a traveling reference line based on a position of the vehicle body caused to travel by the manual steering, an automatic steering controller configured or programmed to perform control by the automatic steering on a set scheduled traveling line based on the traveling reference line, a display to display information about the automatic steering when forward traveling by the automatic steering is to be performed, and a notifier to issue a notification of the information about the automatic steering aside from the information displayed on the display when rearward traveling by the automatic steering is to be performed.

Working vehicle including steering control

A riding management machine includes a traveling vehicle including a vehicle body, an operator's seat provided on the vehicle body, and a hood provided in front of the operator's seat, a working device attached to the traveling vehicle, a position detector to detect a position of the vehicle body based on a signal from a positioning satellite, and a support body to support the position detector above the hood. The support body includes a pair of struts on opposite sides of the vehicle body in a vehicle-width direction, a connector to connect tops of the pair of struts to each other, and reinforcements to connect the respective struts to the vehicle body.

Riding management machine

A working vehicle includes a steering device to steer a vehicle body, a working device connected to the vehicle body, an automatic steering controller to perform automatic steering of the steering device based on a difference between a scheduled traveling line and a position of the vehicle body, and a parameter changer to change a control parameter of the automatic steering depending on the working device connected to the vehicle body.

A working vehicle includes a steering handle, a vehicle body to travel with either manual steering by the steering handle or automatic steering of the steering handle based on a traveling reference line, an operator provided to the vehicle body, and a controller to terminate the automatic steering when the operator is operated under the automatic steering.

A working vehicle includes a steering handle, a vehicle body to travel by manual steering via the steering handle or automatic steering for the steering handle based on a scheduled traveling line, a setting switch to switch between valid and invalid, a setting mode to set at least the automatic steering before the automatic steering is started, and a display including a driving display portion to display driving information of the vehicle body during traveling. When the setting mode is switched to be valid, the display changes a displaying state of the driving display portion to another different displaying state different from the displaying state where the setting mode is invalid.

Working vehicle having a display for displaying driving information thereof

A tractor includes: a driver seat on which a driver can sit; a hoodprovided in front of the driver seat; and an antenna unit that receives satellite positioning information. When viewed from the front, an upper end portion of a ROPS and at least part of the antenna unit overlap with each other.

Tractor and working vehicle

A working vehicle includes a steering device including a steering handle, a vehicle body to travel with either manual steering by the steering handle or automatic steering of the steering handle based on a traveling reference traveling line, and a controller to permit automatic steering based on steering angles of the steering device obtained when the vehicle body travels a predetermined distance while being steered by the manual steering.

A working vehicle includes a vehicle body to travel, a steering handle to be turned to steer the vehicle body, and a steering switch to steer the vehicle body separately from the steering handle. The steering switch may be a switch to be operated in a pressing manner or in a sliding manner to steer the vehicle body. In addition, the steering switch may be arranged around the steering handle.
