Thank you, yes, three people adjusted the clutch with no luck, but left the unnecessary adjustments way out of whack according to the manual specs, so I'll reset those after I replace the clutch

What range are you trying to move it in?

I'm not really sure what's inside ... But a clutch would slip a lot less easily in Low, compared to Medium or High ...

When you say the PTO starts out fast, then slows down, how much? IIRC there is a mode on the dash readout for PTO RPM, is that what you are looking at?
The Pto speeds up with engine revs but when i try to move forward the speed drops right back to similar speed to tractor...barely turning. im not using the readout for PTO and wasent aware there is one .

I don't have the service manual (WSM) with me, but I'd check the adjustment of the clutch first, before splitting it ... But I do have an extra copy of the owners manual with me in my truck, I'm a long distance truck driver ... If you press the button labeled #2, it will cycle through these 5 categories shown on the right page, it will display the actual RPM ...

when i push down with two fingers on the clutch pedal ..hardly any pressure and it seems to go to neutral so requires very little pressure suggesting to me that the clutch plate and clutch are only just touching each other ..

There is nothing on dash for pro rpm .. just tells me that PTO is disengaged when it’s disengaged as I cycle through
The PTO output shaft slows down when I engage forward or reverse with the HSt rocker pedal and will get very slow but if it’s separate clutch why?

The only way I could see that happening would be a damaged hub or shaft on the PTO drive.

Real simple, we can all keep guessing on what's wrong with it, or you can open it up and know.

am i right in assuming that even if i have low transmission pressure that this wont make any difference to forward and reverse speeds?

i measured pressure at the forward speed port
wsm page 3-S87..Port 2 forward . using a pressure gauge,fluctuating preesure .. lower than spec but is pressure not also influenced via the clutch ..if the clutch is good but the tranny bad i may get lower pressure ,if the clutch is bad and tranny good i might get lower pressure ....is this sort of chicken egg dilema or is there another port i can test at idle that may give a more indicative reading.Thank you

Why are you using the clutch?

I dont know enough to answer the pressure question but either way you are splitting the tractor. If the clutch is bad You stop there.
