M6800 pto problem

[Tx Jim]

Where is the best place to get a shop manual?

I bought a TM for my M4900 at local Kubota dealer.It was $75, it's 3-4 "s thick and very infomative.

Not sure where to get it but you could also call a Kubota mechanic and ask a couple questions about the problem. Chappel tractor is near you in mid-south NH and is very helpful and friendly. I bought an M8950 from them years back and they couldn't have been nicer and shops aren't real busy right now. Years back I twisted my M8950 PTO shaft in a bizarre situation and had my local Maine guy come out and change it. It was before the shaft came out easily and they had to take a few things apart but it didn't take very long.

Your PTO shaft should just slide out by removing a few bolts. It is made this way to allow a swap to a 1000 RPM setup. I'm not positive on this but nearly so. Mine had a cluster of bearings and a geared arrangement. You can look inside then but first make sure you find out if your PTO lever needs to be tied back. Mine was hydraulic over mechanical and it did.
I actually still have my old PTO shaft and it was nearly twited halfway around but did not crack or break. In fact, it baled 2000 bales in that condition. Everyone thought it must be made of Krypton.

Anyway, before I got very far in calling a dealer I would make sure the driveshaft is not binding or some other simple thing is not going on. Narrow the focus.
You could search this site for Kubota manuals and that's where you can find info. "Smart Tractor" comes to mind. Keep us posted on this unusual situation. My guess is your PTO problem is something simple and my M8950 was built like a tank. Tough to figure it out at 20 below with a hard wind however. Good luck; this too shall pass.
Oh, my parts and shop manuals were serial number specific so know your SN#.

Thanks to all. I may give Chappel Tractor a call and see what they say although they could be a hundred miles from me. Something tells me the tractor needs to be split to repair but if it is something as simple as sliding out the shaft from the rear of the tractor and sliding in a new one, that would be great!

After what you say I am GUESSing you have a bad bearing.
I'll give you 85% odds it's not a big deal as long as it is not a bent implement shaft or something simple like that.
The big Kubotas are pretty hard to hurt so look real hard.
I have never seen a bad PTO or split larger Kubota. You can also call the regional sales rep.
These guys are smarter than it would seem.
I bought a tractor from Chappel and I lived north of Bangor, Maine.
It was 100 miles for me to get parts.

I sent you an email. I have the shop manual and parts manual for this tractor so let me know if you need help. I will gladly share.

HC Tractor, I never got your email. I did buy a service manual which was helpful in knowing how the pto is designed from front to back but not so much, for me, in describing how to replace any given part. Do you know if the tractor must be split to replace a bearing or the shaft from the pto clutch to the rear?
