Abstract
An apparatus for controlling the posture of a front loader has booms attachable to a vehicle body which are pivotally movably upward and downward and has a work implement attached to the forward ends of the booms and pivotally movable in a scooping direction and a dumping direction. Each of the booms and the implement are pivotally movable by a single control lever independently of each other or movable simultaneously. The apparatus includes an actuating member for shifting the control lever from a boom raising position to a boom raising and dumping position when the booms are not positioned lower than a specified level. This eliminates the likelihood of the implement tilting rearwardly downward even if the booms are raised, precluding the implement from spilling the earth or sand scooped up.
