Abstract: An electric work vehicle comprises: a battery configured to store electric power; a motor generator conductively connected to the battery; a power transfer device having a power output shaft configured to transfer motive power from the motor generator; and a controller configured to switch between a first mode and a second mode.

Abstract: A position detector is supported to be movable between a first position and a second position lower than the first position. A mounting stay is below the position detector when the position detector is in the first position, and, when the position detector is rotated together with the mounting stay from a state in which the position detector is in the first position, the position detector is moved to the second position and the mounting stay is positioned above the position detector in the second position and covers over the position detector so as to restrain the automatic steering control.

Abstract: An electric work vehicle, which is configured to be driven with use of motive power of an electric motor configured to be supplied with electric power from a rechargeable battery, comprises: a drive controller configured to control driving of the electric work vehicle and including a start determination module configured to determine whether or not to permit the electric motor to be started; a display unit configured to display vehicle state information regarding the electric work vehicle and including a start permission indicator configured to indicate that the electric motor is permitted to be started; and a notification controller configured to control display in the display unit.

Abstract: A charging system comprises: a first battery mountable in an electric work vehicle; a second battery mountable in an electric automobile; and a converter capable of conductively connecting to the first battery and the second battery, and also capable of converting first electric power from the second battery to second electric power receivable by the first battery and transmitting the second electric power to the first battery.

Abstract: A work vehicle includes: a body 1; a plurality of travel wheels 2 at front and back portions of the body 1 on each of left and right sides; a plurality of holder mechanisms A held by the body 1 and holding the respective travel wheels 2 in such a manner as to be capable of moving the travel wheels 2 independently of one another relative to the body 1; a detector B configured to detect a state of a travel surface; and a controller C configured to, based on the state that the detector B has detected, control the holder mechanisms A to move the travel wheels 2 relative to the body 1.

Abstract: A traveling work machine includes a position detector capable of obtaining position information of a machine body based on a positioning signal from a navigation satellite, an end determiner capable of determining the end of each of a plurality of instances of work travel, a start position calculator capable of calculating start positions Ls and Ls2, and a display capable of displaying information pertaining to the turning travel. When the end determiner determines the end of the work travel, the start position calculator calculates, based on the position information, the start position Ls2 on one of the left and right with respect to the travel direction of the machine body during the work travel, and the display displays guidance information guiding the turning travel to the start position Ls2.

Abstract: A working vehicle includes an operator's seat, a vehicle body to travel selectively using either manual steering performed manually by the operator or automatic steering performed based on a position of the vehicle body detected by a position detector without manual operation by the operator, and a first operation actuator on a lateral side of the operator's seat to selectively start or terminate the automatic steering during rearward traveling of the vehicle body or to correct the position of the vehicle body during rearward traveling of the vehicle body.

A mounting stay is below the position detector when the position detector is in the first position, and, when the position detector is rotated together with the mounting stay from a state in which the position detector is in the first position, the position detector is moved to the second position and the mounting stay is positioned above the position detector in the second position and covers over the position detector so as to restrain the automatic steering control.

Abstract: An agricultural field work vehicle includes a move-off recorder to record, as move-off information, a move-off position or a move-off travel path, the move-off information being information related to the vehicle body having moved off a target travel path while performing agricultural field work during autonomous travel, the move-off position being a position at which the vehicle body moved off the target travel path, the move-off travel path being the target travel path off which the vehicle body moved, and a work return manager to (i) select a resumption travel path based on the move-off information, the resumption travel path being a travel path on which the agricultural field work vehicle, after the vehicle body moved off the target travel path, resumes performing agricultural field work, and (ii) manage a return of the 1vehicle body to the resumption travel path or the move-off position.
