new owner needs PTO help

[seanhoffman]

I have a model 1720....1991....I bought it used last year and everything worked, or so I thought.....I just bought a bush hog today and I cant get the PTO to sync.....it will sync with nothing attached....Low fluid or bigger problem?

Anyone with some knowledge on the subject?

Thanks...........Sean

It isn't a fluid problem. It sounds like a clutch out of adjustment or worn out to me. When you say "sync" do you mean it won't shift into PTO or that once shifted the PTO won't turn to drive the cutter? You have a 2-stage clutch. Does the pedal have 1/2" to 3/4" freeplay? I think the PTO portion of your clutch is probably slipping. I don't have any direct experience with your tractor so maybe someone else will more complete advice.

Sean,

did your PTO ever worked since you bought the tractor? did you ever use any implement that used pto before? does the gear grind when you try to engage the pto?

with the engine off, engage the pto manually, start the tractor, with tractor in neutral, your foot off the clutch pedal then, does your pto final shaft turn?

if it does, then clutch all the way, does your pto stop?

What exactly do you mean by not synching? do you mean grinding or not pto shaft turning.

post back and we'll try to help. I hope as jim said your clutch pedal need adjustment.

JC,

This is the first PTO driven implement I have tried to use since I bought the tractor.....

Specifics........

The PTO will engage with no problem/noise without any attachment....Once spinning it sounds like all the PTO's ive heard.

Once I install the implement, the PTO wont engage. It makes a grinding sound.

I'm guessing that it is clutch related, but my lack of experience is showing.
I dont have a manual to refer to.

There is a small plug right behind the seat. I was told that that is the fluid fill....It is dry as a bone.....

I need to know if this affects the clutch and then in turn my problem.
Also how do I check fluid levels.

Thanks for your help

on 1720 pto is not independent with a hyd clutch pack. it is live wit dual stage clutch. there is nothing hydraulic/oil related with your tractor. small plug behind a seat, can you take a picture of it, On my 1700 I have a breather cap and not an oil fill. You said it is bone dry, how did you figure that? any dipstick? visual? your hyd system and transmission uses the same oil, bone dry and you have both transmission and hyd pump issue? on my transmission fill plug there is an integral dipstick that you check oile level. you are talking two different issues. Do the test as I suggested in my previous post about clutching, half clutching, pto rotation and report back. Your pto clutch disk might be bad or your final pto shaft coupler may be chewed out. I have to check with your model, I think you have an internal ORC (Over runningclutch) that might be busted. some owner had issues with ORC and ended up changing it.

Let me test it like you said and I'll get back to ya.

I'm thinking I'm going to have some work ahead of me.....

JC,

my dad is with the tractor, and says that the tractor wont start up with the PTO engaged....I do have a question.....there is a secondary foot pedal just below the brake.....That wouldnt happen to have anything to do with the PTO would it.

You just need an operator's manual so you can understand the basic stuff.

So does that mean the pedal below the brake is the PTO clutch?

 

[Willl]

The little peddle by the brakes is probably your differential lock.

Maybe it's your method of trying to engage your PTO, not having a manual and beings first time, could happen.

Push clutch all the way to floor or as far as it will go and keep it there,,,,slowly ease PTO lever in,,,,do it slow, gears need a few seconds to spin down and line up.

Also, I have been told to always have engine at an idle when engaging PTO.

which one is it? pedal under the clutch or brake. if it is on the right side it most likely is the gas pedal (you can rev up the engine). On the left side I don't know. you might take a picture and post. I do not own 1720 to know all the differences, but they share a lot of common stuff. As Rick said, a cheap $20 plus IT service manual or owner's manual can answer some of the basic question.

do you know how a single clutch system work? with dual clutch like you have there is one assembly with 2 clutch plate and two pressure plates that work as a unit. they share a common clutch pedal, push the clutch half way and it disengages transmission and all the way it disengages PTO clutch.

The basic is really need to be learned and understood, and memorizing it is not adequate.

JC,


I went back and looked at onother post you made, you probably have a pto safety switch the keeps the tractor from starting when PTO engaged. start it normally.

Nobody knows everything The key is to know enough to be dangerous
Just ask and good folks around here will try to help out.

JC,

 

[Willl]

most likely is the gas pedal

Didn't even dawn on me that he might be talking about that one. :ashamed:

No sweat... I'm just making it up as I go

The little pedal is the diff lock......I think that my clutch is probably worn.....I appreciate the help......I'm going to visit the local dealer tomorrow to purchase a operating manual, and a service anual......If this is more than a adjustment, how much am I looking at......

I'm not sure if we figured out what is wrong with your pto yet. it will be pricey, as the double clutch part by it self will be close to $1000 and the labor to my estimation is 8-12 hrs as the tractor needs to be split.

You have a 2 stage clutch. This means there are 2 clutch disks. One for driving the tractor and the other for driving the PTO. From not being used your pto clutch is probably stuck . When you push the petal 1/2 way down this stops the movement of the tractor. When you push the petal all the way down this disengages the pto clutch. If you have too much free play in the clutch petal it wont disenguage the pto clutch totaly. The service manual will explain how to adjust the clutch properly. There are ways to free a stuck clutch but you have to have things adjusted properly before trying them.

Well I just left my farm...I got the PTO to engage....It wasn't easy.....quite a bit of grinding, but it did engage.....Didn't sound normal.

Looking at the pedal linkage....it looks like a simple adjustment to increase the throw of the pedal....I just ran out of light.

I hope the manuals i pick up tomorrow will explain this procedure.

I sure hope this is all i have to do......spending 1K on a tractor that I only paid 4K for doesnt sound right....Oh well.....JC the tractor does have just over 2000 hrs on it...

And buy the way.....Tractor supply doesnt have manuals for any Ford tractor built after 1940....in case you needed to know.....

Sent my wife.....boy that was an interesting phone call
