摘要： A haybale handling apparatus is disclosed which includes a support structure mountable on a three point hitch of a tractor, auxiliary wheels mounted on the support structure and positionable to contact the ground thereby permitting the lifting, weighing and loading to legal roadway heights safely of heavy hay bales without tipping the tractor on which the apparatus is mounted, an actuation link movably pivoted at its lower end to the support structure, an intermediate link movably pivoted at the upper end of the actuation link and having a movably lifting link pivoted at its opposite end, a bale claw rotatable by a hydraulic motor about a generally vertical axis and mounted at the free end of the lifting link, said bale claw including a support member and downwardly extending pivoted clamp links which are slidably mounted at opposite ends of the support member with projections at the lower end of the clamp links which may be forced into a bale of hay by hydraulic cylinders operatively connected between the support member and the clamp links and a hydraulic motor for rotating the projections about a generally horizontal axis, and a weighing device mounted on the lift link to determine the weight of each bale.
