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.
