Ford 4000 PTO

I have a 1964(?) Ford 4000. Is there a way to shut off the PTO? Mine runs whenever the motor is running. (this tractor has an "automatic transmission" if that is a factor) There is a lever on under the seat on the right side of the transmission that has two positions. I can't recall how it is marked at the moment, but it does not stop the PTO in either position. I also have a 1948 8N but that PTO stops turning when the clutch is depressed.
 

It's the nature of these tractors with that transmission for the pto to roll when the engines running.
The transmission is called a Select O Speed or as many say SOS.
You need to read up on your tractor, if it has the optional ground speed pto and you engage it and normal pto at the same time bad things could happen.
 

Lever on right side has nothing to do with the PTO! It is your draft/position control lever for your 3 pt.

Your N may be a Ford, But that's about all it has in common with your 4000 SOS!

BTW, your 4000 does not have an automatic transmission. It has a powershift transmission. There is a difference!
 
As Larry said, lever on right side has nothing to do with the PTO.

The PTO on/off control is a handle sticking out of the dash board to the right of the gear selector. You pull the handle out to engage the PTO and push it in to disengage it.

When you push the PTO handle in all the way does the PTO still spin strong enough to drive a heavy implement like a brush hog? If so, then the PTO cable may need adjusting.

If you do not have a service manual for that tractor get one, including the S-O-S transmission supplemental manual. Then change the fluid, adjust the bands and adjust the PTO control cable as per the procedures in the manual. That should get it to the point where the PTO will stop if it has a heavy implement connected to the PTO, but it will still probably spin with no load on it whenever the engine is running as there is no PTO brake.
 
My 1967 4000 with the SOS transmission did the same thing. If I had my bush hog on there the blades would start spinning right at start up. Sean in PA told me to inspect the length of the PTO engage cable system at the T handle and was correct in identifying the problem (Thank you Sean!). Mine was set at 3/4" and it's supposed to be 1 3/8-1 7/16". I set it to 1 3/8" and it stills spins with no load but won't turn if there is a machine on there. Buying a service manual seems expensive but it's the best money you'll spend on that tractor. That and check in with the wealth of knowledge on this forum.

Thank you for the reply. Yes, the PTO still will turn whatever is connected to it as long
as the motor is running. I will pick up the manuals you suggested.
 
Thanks for the reply. Your comment about the transmission raises another question then.
Can the "clutch" pedal be adjusted to act more like a typical standard transmission? Mine
does not. Whenever a forward gear is selected, there is a slight pause and then the gear
engages. If the engine r.p.m. is above idle, it will typically lift the front wheel off the
ground. Makes precision maneuvering impossible. That took some getting used to.
 
Thanks for the reply. I will get a manual for this tractor. In the meantime, can you tell
me how I will know if it has that optional "ground speed PTO"?
 
Problem solved. The cable sleeve was moving with the inner rod so nothing was happening when the T-handle was pushed in and out. Now to find a replacement cable assembly. Anyone know of a source? I don't see that part identified here.
 
That is likely a New Holland exclusive item...if it's still available. Be sitting down when they tell you the price.
 
I found the threads stripped where the conduit connects to the backside of the T handle on mine. Ford says no longer available. All STates Ag Parts has several salvage yards, just gotta find the right guy that knows what you're talking about when you call for it.
 
I tried to take it off but ran into two problems. #1, the end at the transmission does not easily come out. It appears that the cover must be removed from the transmission to disconnect it? #2, can't get the roll pin out of the T-handle so I can try and fix that end. Will have to try and drill it out while still on the tractor? Do you recall what was involved with disconnecting the end at the transmission?
 
"...if it has the optional ground speed pto and you engage it and normal pto at the same time bad things could happen."

With the internal interlock, that should not be possible.

Before I say this, I'm going to issue this word of caution! [b:9cce99e359]If you DO NOT know exactly what you're doing with that transmission, you'd be better off to leave it to someone who does. If you go ahead without that knowledge you'll end up with more problems than you started with![/b:9cce99e359]

That cable is like a big screw! Remove the nut that retains it to the dash (T-handle still connected), unscrew the nut that retains the cable assembly to the transmission cover, loosen the nut that's stripped, push the assembly into the dash far enough that you can turn the T handle clockwise and while exerting a little pull pressure away from the transmission cover unthread the cable. Reverse the process to reinstall.

I do not believe you can fix your current cable assembly. I believe you'll have to find a replacement.

If your tractor has dual speed/ ground speed PTO it'll have two levers on the left side of the transmission, one forward of your footboard and one about where your heal is.

That said, I want to caution you again! With what you've said thus far in this thread, I'm doubtful that you'd help your transmission by working on it yourself. If I'm correct, find someone who knows, and pay them to do it! It'll cost you less in the long run!

I was thinking that too, Bern. If the interlock is working properly it isn't possible.

Why do you need to remove that cable anyway? If it's just an adjustment you're after, there's no need to remove the cable nor is there a need to remove the pin from the T handle.

Also, don't mess with the transmission cover! There's no need for it to be removed for a simple cable adjustment either.

Oops! If I could, I'd delete this one! I see where you said the cable assy is problematic! Well! Except maybe for the transmission cover comment.
 
I don't see any levers on the left side. I have attached pictures. Am I missing something?

OK, your pictures show that you do not have the dual speed PTO, so the only control for the PTO is the handle on the dash.

You need to get the manual and go through all of the band adjustments. That should smooth it out some, but it is not a clutch pedal, it is an inching pedal and it controls a valve in the control valve block that simply dumps the fluid back to the sump when the pedal is pressed down and allows the fluid to continue on to the rest of the control valve when the pedal is raised, so it will never be "like a clutch" in the way that it works to engage the gear that has been selected.

GET THE MANUAL. DO NOT TRY TO TAKE ANYTHING APART WITHOUT READING THE PROPER PROCEDURE IN THE MANUAL OR YOU WILL AT THE BEST BE MAKING MORE WORK FOR YOURSELF, AND AT THE WORST POSSIBLY BE DAMAGING SOMETHING THAT WILL END UP BEING VERY EXPENSIVE TO REPLACE, IF YOU CAN FIND THE PART. The PTO cable will come out if you know the correct procedure. I am actually sorry that Larry gave you the procedure, as that may make you feel like you can do more without having the manual and you might regret that.
 

The guy is asking for help Sean! And I believe I gave him fair warning along with it! Now it's not your decision what he does . . . nor mine! It's his decision . . . as it should be! If he makes the wrong one, it's his own fault and certainly not mine!
 
Larry - Not trying to blame anybody for anything, especially when nothing bad has happened yet. Just trying to instill the proper respect for a piece of equipment that he obviously does not know enough about yet.
