ABSTRACT:
A bucket bale spear bolts together upon a frame, that slips upon the cutting edge of a bucket, and then one bolt secures the frame to the bucket. The frame receives a spear and two balance spikes upon a bracket. A centered tube accepts the spear and secures it with a transverse bolt. The tube provides additional bending resistance for the spear at less weight than a proportional length of spear. The balance spikes also bolt to the frame. The frame, spear, and balance spikes can be shipped and merchandised compactly. At the farm or the ranch, the bucket bale spear assembles readily with hand tools.
