The shovel member is mounted upon a lift arm structure which is pivotally mounted upon the frame of the apparatus at a point behind the front axle. Both the toggle lever device and the hydraulic power cylinder mechanism are pivotally attached to the frame of the apparatus and are located behind the front axle. The power cylinder operates to actuate the toggle lever device and it is connected thereto at a point other than the buckling joint of the toggle lever. Furthermore, the power cylinder is located rearwardly of the point at which the rear end of the lift arm mechanism is pivotally connected to the frame.
