A small or mini loader is operated by a platform standing on the ground or other
surface supporting the loader, and at the rear of the machine. Hydraulic control
levers operate drives on opposite sides of the machine, and the control levers
are pulled rearwardly from a stopped position to effect the rearward drive. A pivoting
panel is mounted on the rear of the frame and has a wall portion that protrudes
outwardly from the rear of the machine. When the lower end of the pivoting panel
engages an obstruction or other item that provides a force tending to move the
lower end of the panel forwardly relative to the frame, an actuator arm will move
to cause control levers that are in a rearward drive position to be moved to the
stopped position.
