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.

Working vehicle

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 Ls, 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 Lson 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 Ls

Traveling work machine

A work vehicle that includes: a transmission system decreasing or changing a speed of a driving force from an engine and outputting the driving force. A transmission case houses the transmission system. A hydraulic circuit supplies oil collected in the transmission case to hydraulic equipment. The transmission case is divided to form a storage space housing a minimum speed transmission portion of the transmission system. The hydraulic circuit connects a suction intake oil passage of the hydraulic circuit to a bottom portion of the storage space and supplies the oil collected in the storage space to the hydraulic equipment.
