Abstract
A work vehicle includes an operating lever configured to operate a work implement, an actuator configured to move the operating lever, and a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever.
Claims20
A work vehicle comprising:
- an operating lever configured to operate a work implement;
- an actuator configured to move the operating lever;
- a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever;
- and
- a first urging member urging the operating lever to a neutral position in the operating range,
- the operating lever being configured to be movable to the retreat position by the actuator against an urging force of the first urging member,
- the operating lever being configured to be movable longitudinally and laterally through the operation range to control the work implement.

A work vehicle comprising:
- an operating lever configured to operate a work implement;
- an actuator configured to move the operating lever;
- a control section configured to perform a control of operating the actuator to move the operating lever to a retreat position when
- acquiring information to determine that a human operator gets on and
- determining that the operator gets on;
- and
- a first urging member urging the operating lever to a neutral position in an operation range,
- the operating lever being movable to the retreat position by the actuator against an urging force of the first urging member,
- the operating lever being movable longitudinally and laterally within the operation range to control the work implement.

A lever unit comprising:
- an operating lever configured to operate a work implement;
- an actuator configured to move the operating lever;
- and
- a holding part configured to hold the operating lever at a retreat position outside an operating range of the operating lever
- a first urging member urging the operating lever to a neutral position in an operation range,

4 more elements
An actuator automatic control method for automatically control an actuator of an operating lever for operating a work implement, the actuator automatic control method comprising:
- generating a control signal of the actuator to move the operating lever to a retreat position outside an operation range of the operating lever;
- and
- transmitting the control signal to the actuator,
- a first urging member urging the operating lever to a neutral position in an operation range,
- the operating lever being movable to the retreat position by the actuator against an urging force of the first urging member,
- the operating lever being movable longitudinally and laterally within the operation range to control the work implement.
