A work vehicle includes a vehicle body, a work implement including a boom attached to the vehicle body and an attachment attached to a tip end part of the boom, a first actuator configured to rotate the boom up and down, and a controller configured to execute an automatic lowering control in order to automatically rotate and lower the boom. The controller is further configured to set the first actuator to a floating state when it is detected that the attachment has reached a predetermined position during an execution of the automatic lowering control.

Work vehicle

A work vehicle includes a vehicle body, a work implement including an attachment, an operating device and a controller. The operating device can be operated to a dump side and a tilt side to cause the attachment to dump and tilt. The controller executes an automatic drive control in which the attachment is caused to dump as far as a predetermined dumping position when the operating device is operated by a first dump operation amount or greater to the dump side, or to tilt as far as a predetermined tilt position when the operating device is operated by a first tilt operation amount or greater to the tilt side. The controller disables the automatic drive control when a switching time period required for the operating device to be switched between the tilt and dump sides is at least a predetermined disabling time period.

Work vehicle with automatic dump and tilt control and method for automatically controlling dump and tilt operations of work vehicle

A work vehicle includes a vehicle body, a work implement attached to the vehicle body, an operating device configured to operate the work implement, a controller configured to drive the work implement at a driving speed corresponding to an operation amount of the operating device, and an input device. The controller is further configured to execute an automatic drive control in order to automatically drive the work implement as far as a predetermined position at a driving speed set in response to an operation amount of the operating device when the controller has received an input from the input device while the operating device is operated.
