An adjustable row crop cultivator is mounted on a tool bar which is vertically movably mounted at the rear end of a tractor. The cultivator includes a plurality of spaced-apart adjustable cultivator units which are vertically movably mounted on the tool bar. A gauge wheel assembly is selectively vertically movably mounted at the forward end of each of the cultivator units. A first mounting plate is positioned at one side of the cultivator unit and has cultivator tools mounted thereon. A second mounting plate is positioned at the other side of the cultivator unit and has cultivator tools mounted thereon. The first and second mounting plates are horizontally movably mounted so that they may be moved towards one another and moved away from one another. The cultivator units may be adjusted by the operator of the tractor from the tractor while the tractor is moving.

A working vehicle includes a travel vehicle body, a traveling device to support the travel vehicle body such that the travel vehicle body is allowed to travel, a changer including an actuator to change a track width of the traveling device, and a controller configured or programmed to perform a first change control in which the controller repeats a drive control until the track width satisfies a target value, the drive control being a control to drive the actuator such that the track width reaches the target value. The controller is configured or programmed to perform the drive control and an idle control alternately from when the first change control is started to when the track width satisfies the target value, the idle control being a control to not drive the actuator for an idle time.
