ABSTRACT:
Drum handling apparatus having a generally vertically oriented main frame member attachable to a standard tractor three-point lifting hitch. A base plate slidable under the drum to be lifted is attached in substantially transverse relation to the lower end of the main frame member, and a latch means engageable with the upper rim of the drum is pivotally attached to the upper end of the main frame member. Rearward movement of the apparatus causes the latch means to engage the upper rim of the drum and the drum is tilted rearwardly by contact with the frame member, allowing the base plate to be slipped beneath it. Operation of the tractor hitch elevates the drum handling apparatus to engage and lift the drum upon the base plate.
