Just finished rebuilding the gearbox on my 3pt S4242 Bush Hog mower. Did a bit of dusty mowing with it & it cuts nice. Also got my front snow blade mounted on my 2nd JB tractor. I'll get pics of both later. Time for supper at the moment & I'm hungry!

I have never seen one of those. It looks cool with the Ag tires. That is awesome. How wide is it? Three?

Already a dramatic transformation! Nice job! Was there anything drastically wrong, or just cleaned it up inside?

Had to have all new bearings & cup races. One bearing was completely blown apart. Plus someone had added shims behind gears and I didn't know if factory or not, as the manual a friend sent showed NO internals of the gearbox, so nothing to go by. Ended up taking the shims out except for one, and lo & behold the gears meshed perfectly. The output shaft area where the seal runs was eaten up with deep pitting. Had to chuck it in the lathe & turn down till it would fit a common seal dimension. Polished the newly machined area till glass smooth. She seals perfectly.

That's great Dan! I'll bet it's really nice to have a lathe around and know how to use it. I've worked on milling machines before, but never a lathe...Wished I had one a few times tho!

I found out that the JB's rear pto output is around 900rpm. The rear pto I fashioned on my custom JB spins almost 1100rpm at full throttle, but works well with this. Most garden tractor rear pto do run at 2,000rpm though.
