Having looked, but unable to find. I'm looking for a 1:1.3 (or so) PTO gearbox. I want 540 output, but don't want to run the tractor at full throttle. The tractor has plenty HP at the lower RPM. Deere offered this as a factory option, but having it installed after, well might as well buy a new tractor..... I can find pto speed DEcreasers but most are based on worm drive which can't be back fed. So, before I do the DYI approack, I thought I would see what the group know about.
