DEVICE FOR LIFTING AND LOWERING IMPLEMENT IN WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To control the lowest position of an implement by a simple operation and to prevent unexpected lifting or lowering just after the on-operation of a power source in a working vehicle for lifting and lowering the implement by the operation of a position lever. SOLUTION: A safety mode is practiced just after the on-operation of the power source, and a lift arm is not moved even if the lift arm is positioned at the side lower than the lowering-controlling position. When an operator moves the position lever to coincide the position of the lift arm therewith, the safety mode is released to enable the lift arm to be turned.
