Day I picked it up.
Gearbox is rebuilt in this pic & mowed with it. May not paint till winter or longer.

I have never seen one of those. It looks cool with the Ag tires. That is awesome. How wide is it? Three?
3 1/2'...42" cut.

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 is cool and useful too. i am looking for one like that but it would have to be 2000 rpm?
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.
