I just replaced everything on the top transmission shaft. I?ve been driving it around gently to be sure everything works. No problems until today. Put the mower on today and used it for a couple hours. Before I got done, it was just as hard to shift from 3rd to reverse and reverse to 3rd as it was before. When I?m not using the pto and running lower rpms it shifts fine. I?m wondering if the clutch is dragging when it gets warmed up and not letting the top shaft stop turning so it drops into gear easily. The adjustment bolt for the clutch is at the bottom of the slot. Neither clutch has been slipping under load. That?s a lot of money spent to still have it grinding. Thanks for any advise.
