Hello, My Dad has a Twin-Wheel Drive sickle mower that went on the back of his D14. He never used it so he gave it to me to cut hay with ( can't afford a mower/cond. ). I plan on converting it to 3 point to put behind my Oliver. My question to you AC guys is how do I find out what model it is? I don't think it is a #7 because it didn't use the snap coupler bell hook. Instead it used a adapter that mounted underneath. This mower doesn't have trailing wheels . It was a fully mounted mower. It was a rear mount and not a side mount also. It doesnt use the wooden pitman arm either. The only markings I saw on the mower was the case that said Twin-Wheel Drive. Is it a #80 or #82 and how do you tell . Any info is appreciated.

When I started farming in 1972 I had a mid mount mower on a D17- I think it was a Model 80. Check various castings for 80 or 82. You do not have a pitman drive because it was twin-wheel: that let the bar operate at extreme up and down angles, which a pitman drive would not do. The 80R was rear mounted, the 80S was side mounted. AC also made a trailing mower with wheels with twin wheel drive- it eliminated the pitman arm, but the bar connecting to the sickle was a major wear point, and had a breakage problem.

From what I can gather, both the # 7 & the 80R have bushings at the main pivot points (at the ends of the gear box)and the 82R has ball bearings. If you're lucky enuf to have the 82R, you will also have a thicker, stronger bar and a heavier "cage" around the gear box.
