I have a Long 510, it is a good tractor but during hay season we were baling with it and the rpm's suddenly jumped to full throttle then came back down to normal. It did this a few times then quit. Changed all the filters, bled the system and it ran fine for a couple weeks then it did it again...
I have a MF 31 sickle mower and the bearing behind the pulley on the wobble box is shot. I may have access to a parts mower with a good wobble box. How hard is it to change out the wobble box versus changing the bearing if the bearing is even available? I haven't had a chance to look at it...
