up/down control mechanism

I have a problem with the adjustment on the control arm on my hydraulic three point system...All the adjustment seems to be at the very bottom of the throw. The first inch or so and its dramatic and hardly controllable. Is there any way to adjust the arm.......my other 9N is much easier to control the up and down movement.
 
remember.. your 9n/2n's DO NOT have position control.

They have draft control for plowing and ground engagement implements.

One thing you can do is make sure there is no slop in the control fork to the control T valve.

Past that, if you want fine(er) (position control ) of the 3pt, you will need to make or build a feedback jig that mechanically
senses movement at the 3pt arm, and adjusts the 3pt handle accordingly. They are simple systems using friction washers and
linkage.

Zane makes and sells one called the Zane thang.

There were models out for fergy's called the ferguson positioner.. etc.

We have seen 1 or 2 home made ones posted here throughout the years as well.

not sure what that is.......

still don't understand the system I guess........I just know my first one that I have been using for years works fine and I can control the position of the blade I have on it but this one I just recently rebuilt.(the Blackbird) just has a dramatic up down movement at the very bottom of the throw.......

he quadrant is bolted to outside of lift cover by 4 bolts in slotted holes. You may want to try re-positioning it fore/aft to see if that will put touch control lever more in mid range of movement.
 
This is where you need to know more about your tractor than what a paint can can tell you.

on the 9n / 2n, the lift cover and lift control have a control fork that moves a T shaped valve in and out of the pump.

It's a completely different system than an 8n ( ferguson lawsuit.. )

You will actually.. have to open your parts and service manual to see the stuff I'm talking about.

If I had a pic on my phone I'd attach it. If I can find one, I will.

lets see if these diagrams post.

this diagram shows a fergy part.. but function is the same on the t valve.

As Soundguy says, 9/2N do not have position control. The arms are either up or down. You can easily add position control with
Zane Sherman's device. It is external and only takes a few minutes to install. This device would also correct 8Ns that have
poor position control - although the correct way would be to replace the cam follower pin.

Those pictures don't look anything like what I'm talking about............when your sitting on the tractor there is a lever to your right that you operate..........you push it down to make the lift go down and you pull it up to lift it up.........my first 9N I use to drag the horse arena twice a week and I have a blade on it with a hook welded on it that I hook the chain that is attached to the drag.........I can lift the blade all the way up or let it down to where the blade is hovering just above the ground so I can control the angle of the drag........I wish you had a video soundguy

s some have told you, 9n/2Ns do not have position control. You may, if you re-position quadrant as I told you earlier, make it easier to find a delicate balancing point between lift/lower, but it won't maintain position as does 8N.

On the contrary............As I said earlier........my 39 9N can maintain the blade at any position if you find the right spot on the lever......I do agree its tricky but I hover my blade just over the ground all the time when I drag the arena across the street........every once in a while I have to re adjust it but I can go maybe 500 or a thousand feet in between tweeking it.

And regarding the pictures I really appreciate the effort I really do but It looks like a thousand piece puzzle to me. I think I could take the tractor apart and rebuild the engine easier than understanding those diagrams........I do have a manual and i'll look in it for help but I wish I was smarter and could under stand what you guys mean regarding the live thang an such

ou have learned what has been said over & over, those tractors do not have 8N-like position control, "...every once in a while I have to re adjust it but I can go maybe 500 or a thousand feet in between tweeking it. "

I'm no expert in comparison to other people on this site so my advice may not be correct for this situation.

My take on it is; You use your draft control lever to hover your implement where you want it at that time on your other tractor. You don't have fine control on [i:99c995965d]this[/i:99c995965d] 9N and when you barely use the lever your lift arms move to the top of their range or at least more than you want them to. What you're asking for is help troubleshooting this.

Am I correct?

yes ............my problem is the lever is not smooth like my other 9N.......its dramatic at the very bottom of the throw......the little wing nut stopper is about an inch from the lever being all the way forward or down.......whereas the adjustable stopper with wing nut on my other one I'm driving is in the middle of the throw......
 

That lever you hand rests on to move your lift up and down is connected to linkage s INSIDE the tractor. Those are the diagrams I posted.

You might have some playin the linkages on this one, vs your other which I why they behave different. You have limited external options. If that dont work, internal.
 

I think JMOR told you to adjust the quadrant, do that it is in the manual and you may need to replace the friction disk, it will help hold it in position and not be so erratic
 

after reading all of your suggestions........I looked at the F04 manual and it is pretty explanatory but I'll have to read it a dozen times before It will make sense to my feeble brain......so many little parts......I ordered a Zane Thang and if I adjust my quadrant maybe I'll have better luck controlling the auger when I install the Zane Thang without having to try and figure out how to take the whole thing apart.......

Still don't understand on how you adjust the main spring.....
