ABSTRACT:
A tractor mounted cylindrical hay bale lifter includes a rectangular frame mounted for rotation on the tractor lower arms of the three point hitch. A platform rides up and down the frame side leg guide channels in response to the raising and lowering of the lower arms such that a one foot rise in the platform results in a three foot rise in the platform relative to ground levcel. A spear and studs are mounted on the platform and a hydraulic cylinder connected to the center point controls the angular orientation of the spear and the frame. For jumbo bales, a lift assist cylinder is mounted between the draw bar and the frame to assist the cable lifting system. Lifting is generally vertical to enhance tractor stability. The spear and spear mount is detachable to enable the frame to accommodate other application mounting member.
