I got my highly modified AC 716 out yesterday to do some raking (built the rake too). This tractor was built with parts from AC, Sears, Ford, & MTD. Powered with a Kohler Magnum 18. Ford/Jacobson Eaton/Peerless rear end. 2-spool hydraulics, foot pedal drive. Took me about 3 months to put it together. The 26 X 12's are loaded and 80 lbs. of weights give plenty of traction. Front suitcase weights are lead castings, 40 lbs. each.
