My new PTO pulleys arrived this morning, and ain't they purty!  They will stay purty till after all plow days I might get to go to are over, meaning sometime in November for a start date.  I hope to attend a plow day other than my own if it'll just work out for me, and this tractor is my plow machine, so PTO just has to wait.

No real time to work on any projects, but I did install my pto shaft into the reversing gearbox.  Fit like a glove!

Where'd you get that reversing gearbox, Daniel?  I'm kinda looking at a Kubota B6000 with the odd, CCW rear PTO and need something to make it turn CW...

Ebay is where I got mine.  They had it listed at $400 with "or best offer".  I sent them a $200 offer & they snapped it up without even a counter offer.  Still a lot of money, but worth it to me.  Here's an ebay listing page for the "Hub City model 22".  The ones with a hollow shaft are type "SO".    The ebay page has an SO at the top of the list, but $399 and no "best offer".

Smitty, these model 22 reverser boxes are designed to handle 25hp at 1750rpm.  I have one just like it on my other JB, and run it at 3,000rpm & no problems at all.  It's just they were built to use with electric motors, so they stamped the 1750rpm rating on them.  They have timken tapered bearings, so they can take it.  Actually, the rating chart shows the HP they can handle goes up greatly as rpm increases, so likely at 3,000, they can handle 30+hp with ease.

The posts about best GT & it's followup thread spurred me to get Hogzilla into the shop so I can begin the addition of rear PTO.  Took the pic with my phone & blurry, but it shows I have it down there.  It'll take a while, but hopefully operational by late spring.  I decided to go with an electric pto clutch for 2 reasons, one being simplicity (no engagement levers), and the other because I have a good clutch.

I'll try to get pics later.  I got some work done on the PTO today.  Then had to get to farm work.  But I got the tractor's rear plate extended 2 1/2" to allow room for the pulleys, made some gearbox mount bushings, and mocked up how it will all go.  I still have to extend the OE John Deere rear pto shaft 6" then cut 5" of 1/4" keyway into the extension part.  JD builds their stuff odd sizes.  The OE shaft measures .985 instead of an even inch, so for a true running shaft, I'll pick up a 15/16" "weld-a-hub" at TSC, then machine 1/2 way through it for a tight press fit of the 1x6" extension, then the other half machine for a tight press fit of the .985" shaft, then weld.

 I would go to TSC tonight for the weld-a-hub and some grade 8 bolts to mount the pto gearbox, and a 5/8x32" V belt, but the roads are still slick, totally white, as no state trucks have come through with their snow blades or salt.

I know about the white roads. I think a County truck came through and spread salt, but that is all. Just remember, I sit atop a hill. The only ways out are downhill!

So getting out is easy, but getting back is a PITA

 JD builds their stuff odd sizes.  The OE shaft measures .985 instead of an even inch, so for a true running shaft,

 

Daniel, That may be a metric shaft and if so it a 25mm. conversion show it as 25.019mm

It's metric then, as I just used a cheap dial caliper good to within .001".  So I was only +/- .00075 off.
