Electric Work Vehicle

Abstract: This electric work vehicle is provided with: a motor control part for controlling a motor (M); power take-off shafts (17), (18) that can be connected with a work device and transmit, to the work device, rotary power from the motor (M); and a distribution mechanism (20) for distributing the rotary power output from the motor (M) into a hydrostatic continuously variable transmission (15) and the power take-off shafts (17), (18). The hydrostatic continuously variable transmission (15) is configured so that the rotary power input into the hydrostatic continuously variable transmission (15) is shifted and output to a travel device. With the motor control part, maintenance control can be performed in which the output rotation speed of the motor (M) is maintained at a rotation speed corresponding to the target rotation speed of the power take-off shafts (17), (18). The hydrostatic continuously variable transmission (15) is configured so that, when the maintenance control is being performed, the gear shift state in the hydrostatic continuously variable transmission (15) can be changed according to manual operation of the speed change operation tool.
