I finished my first round of hay. My pto seems to be noisy. Sounds like a bearing is gone or some gears are not meshing prroperly. Has any one had rebuilt their pto on a DB880 selectomatic? I want to know if I take it apart and replace bearings etc, can I have it going in 1-2 days. What kind of job is it? It looks fairly simple in the manual. Are all the replacement parts available? Should I wait until hay season is over? I have 30-40 acres left to do.
