A work machine according to the present invention includes a manual operating tool configured to operate a hydraulic actuator; an operation amount detector configured to detect an operation amount of the manual operating tool; a hydraulic pump configured to generate a hydraulic pressure to be supplied to the hydraulic actuator; an electric pump motor configured to change an output characteristic of the hydraulic pump in response to a rotary force to be given to the hydraulic pump; a motor load detector configured to detect a motor load of the pump motor; and a pump motor controller configured to determine a necessary output characteristic based on the operation amount and the motor load and control the pump motor based on the output characteristic.

Work machine

A work vehicle includes travel devices; a battery; a motor; an inverter configured to operate the motor; an operation section including a steering wheel configured to operate the travel devices, and an operator seat; a transmission case housing a transmission for travel; and a transmission shaft, wherein the motor is between a front travel device and a rear travel device in a side view and below the steering wheel, and the motor, the transmission shaft, the transmission, and the travel devices are configured such that motive power from the motor is transmitted to the transmission via the transmission shaft and transmitted from the transmission to the travel devices.

Work vehicle

A work vehicle including a travel device supporting a body of the work vehicle in such a manner as to enable the body to travel; a power take-off shaft configured to output power out from the body; a travel electric motor configured to drive the travel device; a work electric motor configured to drive the power take-off shaft to rotate; a power-transmission-state switching mechanism configured to be switched between (i) an independent power transmission state in which output from the travel electric motor is output to the travel device and in which output from the work electric motor is output to the power take-off shaft, and (ii) a cooperative output power transmission state in which the travel electric motor and the work electric motor are capable of cooperatively outputting power to a drive target; and a control unit configured to control switching of the power-transmission-state switching mechanism.

A work machine includes in its driver section, a driver's seat; and a tool container disposed below the driver's seat and configured to store a tool.

Work machine with tool storage below driver seat

A work vehicle includes travel devices, a battery, a motor configured to supply motive power to the travel devices, an inverter configured to operate the motor, and an operation section. The battery is between a front travel device and a rear travel device in a side view, and below a floor of the operation section.
