Sweet sorghum can be readily grown in the Eastern U.S. Piedmont, but irregular-shaped fields on rolling terrain present a challenge to mechanical harvesting. An Atkinson sugarcane harvester was converted from a three-point hitch to a pull-type machine. Gathering chains captured the stalks as they were cut at the base, and elevated them at a 30° angle. The stalk was gripped between two rotating disks and flipped to the horizontal position. Disk tangential velocity was 24% greater than chain velocity. Total power required was 33 kW (44 hp) with 67% for the chains and 28% for drawbar pull.
