ABSTRACT:
An apparatus for bale lifting and load dumping, including a support frame; a truck bed overlying the support frame, the rearward end of the truck bed being pivotally attached to the rearward end of the support frame; a lift arm articulating beam, the lift arm articulating beam being pivotally attached to the rearward end of the truck bed; a pair of bale lifting arms extending substantially perpendicularly from the lift arm articulating beam; an actuator having an alternately extendable and retractable shaft, the actuator having a first end and a second end, the first end of the actuator being pivotally attached to the support frame; and a linkage interconnecting the second end of the actuator and the lift arm articulating beam; the connection of the linkage to the lift arm articulating beam being positioned so that upon alternate restraint of pivotal motion of the truck bed about the pivotal attachment to the support frame, and restraint of pivotal motion of the lift arm articulating beam about the pivotal attachment to the truck bed, operation of the actuator alternately pivots the lift arm articulating beam about the pivotal attachment to the truck bed, and pivots the truck bed about the pivotal attachment to the support frame.
