Thanks for the tip, Paulemar. Triple R, although I did research Yanmars, I did not research the 2200 specifically - until I saw a reference last night about it being an orphan. Had no idea of this issue. Apparently this was stated 6 yrs ago. I hope things are better. I lost a pin today (one of the two that secure one or the two lower pto arms to the bottom of the frame 22mm by 3 1/4") and was unsuccessful finding a replacement.
Do you have any thoughts or info to share?
