They're JD parts, but they just happen to fit Gleaner. The belts are standard widths, and the lengths just happen to fit some JD application, or the bearings fit a standard shaft size, etc.
Thats an awfull price even if you are talking Canadian. Why don't you email me for I may have a line on some like new parts if it isn't to late. Did you have the tractor S_N and P_N of bearing that failedIJ I've only had a fairly major problem with one of these tractor transmisions out of warrentee and we fixed up with like new parts much cheaper. Catch you later
