I recently bought an AC 916 garden tractor. It has a one-cylinder, 16hp engine, hydrolic lift, came with 48" mower deck, 36" tiller, a plow, and some other plow-looking thing. It was purchased new in 1984....for $5,000, believe it or not. Seems like a lot of $, especially for 20 yrs ago. I didn't know AC made garden tractors. I need to buy a certain electrical part to put the starting system back to original, and I need to adjust the PTO clutch, as it smokes (I hope it's within adjustment).Does anyone have any experience with these tractors? Any hints? Suggestions? Kohler engine.
