PTO not working

[search4one]

Are you sure the shift forks are hooked up? In the past I have had mine loosen up and fall out of place with the shifter

Yes, as I said in an earlier post, I can get the PTO to turn and stop by engaging and disengaging it. But I can stop it with my hand and of course it will not turn any equipment.

Do you have an over-running clutch on the PTO shaft where it comes out the back? When you were operating a brush cutter, did the PTO disengage when you pushed the clutch?

I would suggest you get a parts manual. I just read over a thread where Len Sheaffer got a parts manual for some gentlemen. Hoye may have them, that I don't know. Sheaffer's Town & Country Tractor

I do not believe I have an over running clutch. I have never operated any equipment with the PTO. Purchased the tractor last winter, tried the PTO and it turned so I assumed it worked.

I have a parts manual but it doesn't show how to access the PTO clutches.

Has it been determined this is anything other than a simple geared PTO? Are there really clutches? If so, could they be driven by hydraulic pressure and engaged/disengaged by UFO commands? (UFO is Yanmar's electronic 3-point control system, not aliens! )

I looked for a cam clutch/ one-way clutch part #. Based on that search, I would say he does not have one. Possibly he has an over-riding clutch on the PTO shaft. That would make his failure a broken shaft or gears no longer in contact. I think he would have heard teeth plucking off.

If it's like yanmar's other units the PTO slides out after you take out the 4 bolts or so...maybe a snap ring or two? I can't remember its been awhile since I looked at the manual.

Man, that would be to good to be true.

You bring up a good point California. I emailed Leonard at Sheaffer Town & Country Tractor and he told me it was probably one of three things, low hyd. pressure, worn out clutches and or a bad O-ring. Pretty sure my hyd. pressure is good. I am supplying a link to the diagrams to the PTO showing the clutches and if you look in Figure 61 Part #17 is an O-ring.

Yanmar F395D PTO Click on the photo and six pages will come up.

One more thing that could possibly be the culprit. I have lever underneath the steering wheel that says "PTO" and some Japanese writing. It slides up and down and seems to have three positions. But none of them seems to have any effect on the PTO. Maybe before I tear into the rear end, I will get in there and see if maybe this lever is the UFO you speak of and it is not connected.

Thanks for everyone's response.
