Abstract
Apparatus adapted to be attached to the boom arms of a conventional tractor supported front end loader for use in engaging, lifting, unrolling and performing other handling requirements of a large rolled round bale of hay. The apparatus includes frame elements designed to be operatively and removably secured to the boom arms of a front end loader to provide operating support for a pair of horizontally spaced and adjustable bale clamping arms, with an actuator operatively connected to the bale clamping arms and operable of effecting adjustment of the bale clamping arms between a closed bale clamping position and an open bale release and receiving position. A pair of disk elements are coaxially and rotatably mounted on the extended ends of the bale clamping arms and detailed to include bale engaging projections whereby a bale can be engaged and rotatably supported by the disk elements between the clamping arms. Conventional adjustment of the boom arms will permit the bale to be elevated in loading and other bale handling operations.
