Here are some n from a 84 IT manual. 7720- 860- 8820 HP. 165-183(200 on late late models)-225 Cyl 55-60-66.5 width all 22 dia. Concave Area 1150-1350-1377 sq in. Walker Area 8222-10104-9867 sq in. Cleaning Area 5637-6142-6799 sq in. Grain tank 190-180-222 bu. The 860 will almost match the 8820. The place where the 860 really falls behind the 8820 is in clean grain handling. No problem handling Small Grains Or Soys. But in Really good corn you can over load it with a 6 row head. HTH. Joe
