ABSTRACT:
A hay handling device is mounted in a vehicle bed to load, carry, and unload large hay bales. A rugged frame of the device is securely held in the vehicle bed by brackets which release the frame in selective fashion to permit its removal. A horizontal support member which is pivoted to the frame carries a central spear which is adapted to penetrate a bale resting on the ground. The spear is secured to a small sleeve which is slidably mounted on an upright post so that the elevation of the spear can be adjusted in order to accommodate bales of various sizes and vehicle beds of different heights. Shorter spears are located on opposite sides of the central spear to cooperate in handling the hay bale. A power winch operates on the upright post to pivot the support member in a manner to raise a bale which the spears have penetrated.
