I will someday be adding rear PTO to my JBI Diesel (Hogzilla). I am trimming my herd a little if I can find some buyers (NOT selling any Bush Hogs) and I want my JB Diesel to be my main workhorse for garden work. That means it needs rear pto. I had thought of building my own gearbox to reverse my rotation to match attachment rotation, and I had already gotten bearings, steel, and seals to do it, but just don't have the time. I have the tooling to do it, but without the time, it'll never happen.
A while back I bought a NOS pto shaft for a John Deere 430 that will fit my Sunstar hydro perfectly.
Now I finally found a NOS gearbox I could afford. It's the identical gearbox I used to install rear pto in my JBI with the Wisconsin twin TJD engine repower. It should arrive Monday.
I already dug through my inventory & have the pulleys I need to connect the power, being both twin groove 1/2" belt. I also have a new greaseable pillow block bearing to support the end of the pulley shaft that will come off the hydro, similar to the pic below, but mine was actually made in the good ole USA!
I even have a wide tensioner idler & bracket to tighten the belt to engage the pto. I had thought of using an electric clutch, but if I go that route, lots of tension will be on the upper shafts bearing even when pto isn't running. That would lead to early bearing wear, and likely also wear on the splines where the shaft fits on the hydro's output.
So all I can think of that I don't have is the V-belts, and I won't know what length I'll need until I get all components in place......plus I'm still short the time required. I will have to kick back the rear chassis plate on the tractor to allow clearance for the pulley input on the gearbox, and with plow day coming, even if I had some time, I won't dare start this till after my plow day is over. Who knows....might be winter, or even another year before I can get it done.
