Abstract

[Problem]To provide a work vehicle that alleviates a shock that may occur during a speed change by circumventing stalling of a motor caused by a speed increase in a speed change apparatus and also circumventing over-rotation of the motor caused by a speed decrease in the speed change apparatus.[Means for Solving the Problem]A work vehicle according to the present invention includes a rotationally driven motor; a traveling vehicle body on which the motor is mounted; a travel apparatus that is provided to the traveling vehicle body and is also driven by drive power from the motor; a work apparatus that performs work on a farm field; a speed change apparatus that changes the speed of drive power that is input from the motor and transmits the drive power; a speed change operation tool that includes a plurality of speed change stages and is also capable of speed change operation of the speed change apparatus by way of a human operation; a speed change controller that, when the number of speed change stages is changed over a plurality of stages based on human operation of the speed change operation tool, outputs to the speed change apparatus a speed change command for each predefined number of stages and is also capable of outputting the speed change command for each defined speed change interval; and an operation mechanism that enables adjustment of the speed change interval.
