900 Ford PTO question

I have a 5 speed 900 Ford that I took out from winter storage. Now the PTO grinds as I try to engage it. (even when the engine is idling) I can shut off the engine and then I can engage the PTO but is seems stiffer that I remember. It's still cold here today as being in the 20's. Could this be due to stiff oil? The oil is a golden color (not milky at all) but I don't know what weight it is as I purchased the tractor last spring. If not the low temp and oil what would cause the grinding to start now? The tractor does not grind when shifting gears.

Also on the 5 speeds 900's. Do all of this variant have true live PTO? Or do some have the 1/2 clutch down to stop the tractor?

A 900 could have transmission or live pto. What is the middle number of the model stamped on the bellhousing? 950 would have a 5-
speed and transmission (non-live) pto; a 960 has a two-stage clutch and live pto.
The pto being stiff could be from the cold weather. Grinding is not likely to be from the weather. If you have a 960 with live pto,
the grinding may be from a stuck pto clutch.
 
If it's transmission PTO you'd have trouble getting the tranny in gear also. Either way, you likely have a disc rusted to the pressure plate.
Have a friend hold the clutch pedal down with the engine off while you try and bust the PTO shaft loose with a pipe wrench.
 
agreed with fordfarmer. If it's a 960, and it's grinding, stuck pto section, or worn past mechanical use to function. Is your
freeplay set correctly? If sloppy, set it to minimum and try it.. if it works, set it a HAIR below minimum.. and if it works
even better.. you know you are in for a clutch shortly.

fordfarmer Sir,

I checked the casting this morning and it is stamped 960 so it has a live PTO. Well that's good and funny the previous owner didn't tell me that. He said (or I thought he said) you needed to push the clutch have way down to stop forward motion and keeps the PTO turning. Well he was correct but I wasn't bright enough to figure that it didn't make a difference.

OK so I have a stuck PTO clutch from sitting over winter that needs to be freed up.

Your help was much appreciated.

Bern and Soundguy,

Just to make sure I've got this right I need adjust the foot clutch peddle. Correct? Should I free up pressure plate first for the adjustment or after? Or is there a PTO clutch too? Sorry I don't have a service book for this model.

Again your help is appreciated.

THat sounds like the clevis that connects the clutch pedal to the rod is in the wrong hole for pto use. One hole allows for a lower clutch pedal when the pto isn't needed, making it easier to use the clutch. The other hole allows both stages of the clutch to function - part way down to stop the tractor, all the way down to stop both tractor and pto.
In that case... your pto clutch may or may NOT be stuck.
 
Do all of this variant have true live PTO? Or do some have the 1/2 clutch down to stop the tractor?

Sounds like you may be confused as to what live PTO is. Pushing the clutch halfway down to stop the tractor while keeping the PTO powered is true live PTO for Ford tractors. You may be thinking of independent PTO if you think that the PTO is totally independent of the clutch pedal.

non-live PTO (true name transmission driven PTO) is directly linked to the input shaft of the transmission and there is only one clutch, so the PTO only has power when the transmission clutch is engaged.

Live PTO uses a two stage clutch so that the PTO can be powered when the transmission is not being powered. When you push the clutch pedal all the way in it disengages both the transmission clutch and the PTO clutch. WHen you let the clutch pedal up half way it engages the PTO clutch and when you let the pedal up all of the way it engages the transmission PTO as well.

Independent PTO is truly independent of the clutch pedal altogether, and the PTO is engaged whenever the PTO handle is in the engaged position regardless of the position that the clutch pedal is in. The 900 series didn't have any models with independent PTO. The first models to get it were the next generation '01 series (601/701/801/901) and only in the models with the Select-O-Speed transmissions, which were the models with a 7 or an 8 in the middle digit.
 

FordFarmer Sir,

I was confused and remember the previous owner telling me about about the two positions for the clutch pin so when I went out to the tractor and moved the pin the PTO shut off and I was able to engage the PTO as I thought I should. Every think it fine except for my brain... I appreciate your time and everyone's time too to walk me thru my misunderstanding on how it operates.

Hey Dave , sounds like you got it
figured out,but thought I would
throw a picture out there for you.
My clutch pedal is in PTO
position. Clutch pedal is way up
and sorta hard to use. But when I
push it half way down tractor
stops,PTO doesn't. When clutch is
fully pushed PTO stops too. Then
it can be disengaged/ engaged. For
non PTO work move pin to other
hole. Love my 960. How about a
picture of yours? Thanks Kevin in
Central AL how do you like my
rebar pointer?!?

Sean in PA Sir,

Yes I think I am confused, Was confused,

Thanks to you for the explanation.

Well it is confusing in general because of the advent of hydrostatic transmissions, on which the PTO is also called live, but have no clutch pedal at all. I'm not sure why they don't call them independent, but I think it is because if the hi/low range shifter sits before the PTO and it is in neutral then the PTO gets no power so it is "dependent" on something.
 
Grandpa Love,

Here's my tractor. I like your pointer. Looks like a good education tool...
