Patent ID: 8572939

Claim:
A riding work vehicle comprising: a vehicle body having a driver seat; a driving wheel unit supporting the vehicle body; a running electric motor unit which runs and drives the driving wheel unit; a speed setting operation unit operated by a driver to set a target running speed of the vehicle body; a running controller which controls the running electric motor based on the target running speed; a work unit having a work device that performs work on a worked object adjacent the vehicle body corresponding to running of the vehicle body, and at least one working electric motor that drives the work device; a work controller controlling the working electric motor; a work load evaluator that evaluates load of the at least one working electric motor; and an exceptional speed controller that performs exceptional speed control to control the running electric motor unit at an exceptional speed lower than the target running speed in a case where the load of the at least one working electric motor evaluated by the work load evaluator is an abnormal load higher than a threshold value, wherein the target running speed by the speed setting operation unit is canceled until the value of the target running speed by the speed setting operation unit becomes equal or less than the exceptional speed when the exceptional speed control is performed.
