Ford 9n problems

I purchased a 9n runs well, tires good. I am a rookie at fixing it up but would like a winter project. My question is this, when I bought it the owner said he changed the hydraulic fluid and felt he might have over filled. The hydraulics and brakes worked when I purchased this a year ago and it sat since then. Problem the brakes don't work and I can not get the lever to engage the hydraulics to move. It looks like there is fluid leaking around both wheel drums and in checking the fluid level it is low. My question is where do I start? Pull wheels? pull hydraulics? Need guidance, thank you.
 
Start with an I-T FO-04 manual before any thing else.
Hyd fluid low well then wheel seals should not be leaking but yes could have in the past. Hyd control will not move so how long has it sat that way?? You do know the PTO has to be engaged for the hyds to work right??
 
A little more info please.
When you say the brakes won't work, do you mean the pedals
won't move or that they move and have no resistance, or they
move and you can put a lot of pressure on them and the tractor
still doesn't stop? The latter being a sign of oil soaked brakes.

On the hydraulics, which lever are you trying to move?
The one on the right when in the seat or the PTO engagement
lever on the left inspection cover? PTO has to be engaged for
the hydraulics to work so I wasn't sure which one you meant.
 
brakes go down but no pressure will slow me down. The lever I am referring to is the PTO lever on the left of driver.
 
I do have manual you refer to. The lever I refer to is PTO engagement lever on left side of driver.
 
If it will not move then take it off and have a look see why. The lever it self could be locked up but more then likely the sleeve is bad or rusted in place
 
"The lever I am referring to is the PTO lever on the left of driver."

Ok, two different problems in my opinion.
The brakes are probably soaked in oil due to worn axle seals.

The PTO shifter, if it won't engage is a different issue.
Is the handle froze solid from rust and just won't move or will
it just not engage to turn the PTO? Silly question maybe, but if
it will move at all, you do know you have to have the clutch
depressed to engage it right?
Not all tractors are like this, but an N is so sometimes people,
even those with experience with other tractors don't realize that.
 
The lever itself is not frozen but whatever it engages inside will not move, I take it that is what you suggest is frozen or rusted. I do have an 8n and I did have clutch engaged.
 
You can pull that side cover off and take a look inside.
There is a collar that slides over the end of the PTO shaft
to engage it. Collar is moved by that handle.
Unless it has sat outside for a long time the collar is not
likely to be rusted solid. Hopefully a visual inspection will
tell you what's going on with it.
 
The engagement lever is free. When you talk about a sleeve, are you referring to the sleeve around drive shaft? I can move it about a half inch by hand. My problem is where to hook the lever up to. There is a rail under the drive shaft with it looks like washers separated about 3/4 in. What is this for. If you could refer me to a good diagram showing hook up would help, I can't find one.
 
That sleeve should actually be on the PTO shaft.
When you push it one direction, the PTO is disengaged and you
should be able to turn the PTO at the rear of the tractor by hand.
Push it the other way and it locks the two shafts together.
When locked you shouldn't be able to turn the PTO by hand.
The lever just moves the shifting rail and sleeve back and forth.

I don't have any good pictures of it assembled, but did you
see the exploded parts diagram? It may help.
The shifting rail, part #7 may be what you are referring to
when you say it looks to have washers on it.

I-T FO-04 manual page 30 diagram FO75 has a picture of the sleeve I am talking about. The sleeve has a place in it for the shifter part to set in for shifting the PTO in and out of gear
 
The brakes could be a simple adjustment to needing a whole new set of brake shoes for it.
 
Thank you for response. I looked in my Shop Manual FO-4 on my page 30 is Fig. FO35&36 discussing camshafts. FO-75 is on page 51 discussing ammeter installation. I must have a different edition, I can find no pictures or discussions on my problem.

I usually try to post my own pictures from what I have seen,
instead of posting from a manual, but there are different
versions of the FO-4 manual. My numbers agree with yours.

The picture below may be the one Old was referring to.
In my manual, it is FO-129 on page 86.

Yep that is the one I have just different page numbers. But I do have an older manual and a poor reprint of a newer one I almost never try to use since it is someones company and hard to figure out
 
Thank you very much, I do have that picture on p. 86. I then take from this that the reason I cannot move the lever on the left side of my 9n is that the shift rail is stuck or something broken in there.
 
The splines on the shafts can be messed up or the splines in/on the shifter can be bad either one or both will cause that problem
