Abstract

A commercially available farm tractor having a rear-mounted upwardly swingable power lift, is provided with a pair of hay-bale-penetrating tines rigidly parallelly connected at their base ends by a member that is easily and quickly detachably mountable on the free ends of parallel lift arms. A delta-shaped frame is attached to the front of the tractor to carry a second pair of parallel bale-impaling tines which are upwardly swingable by a single hydraulic cylinder. The assemblage provides quick and easy loading and unloading of two bales, and a weight-balanced load during carrying.
