Hydraulic Question

[BlueLine9N]

Afternoon Tractor people!! Have a quick hydraulic question.

The lever on my 9N has a TON of play in it and it often will not keep the bush hog on the ground without continually playing with the lever while driving. NOW, one of the lift arms is pretty bent and they don't sit level so I already ordered those, but I'm thinking I'll have to rebuild a part of or the entire hydraulic system....

In short - do I buy the rebuild kit that comes with everything less the chambers or do I buy just the chamber rebuild kit?

Your 9N doesn't have position control.

ZANE can help you with that, or simply get some limiter chains to hold the cutter at working height.

 

[BlueLine9N]

Already has the chains...Still doesn't make sense why it would float up and down...My thinking is it has a leak in it somewhere...

 

[BlueLine9N]

I believe It already has limiter chains?

If your pump lifts the weight, chances are there is nothing
wrong with the pump.

As Bob said, no positionontrol on a 9n. You can get an external
position control feedback system to mimic it though.

Limit chains hook to the center link area so that the equipment can only go down so far. The chain in your picture are the side to side limit chains which are a different thing

Can ya post a picture of it?

 

[old]

No I can not since I do not have a picture and have never had to use them but then I do not have a 9N or 2N which need then but the 8N and new did not need them. The chain would run form the center link hook up to the ends of the lift arms so they can only drop as far as the chain allow

This is what you want, I got mine off eBay years ago, pretty sure the same stuff is available.
The ONLY way to go to keep the brush hog at the right height, the hydraulics just don't cut it.
Limiter chains

And from googling, this came up, looks like the right stuff. I know nothing about the supplier.

Your 9n was designed to hold a set pressure on a plow but not a set height . This changed when the 8n came into production .

Limiter chains help support some of the weight and limit the depth so if the mower is raised after driving on uneven ground it will drop back down to the set height .

Here are some good pics ,

P.S. they are not a bad idea for 8n's because driver error can still drop a hog too low

Those are check chains that keep the lower arms from hitting the tires....

Here's some good info on limit chains: (delete ALL the *)

Terminology is important. Learn it and you will be better served here.
Position control - keep the implement at one height setting.
Draft control - sets the amount of ground engagement relative to traction, etc.
Check chains - keep the lift arms from swinging side to side.
Limiter chains - keep the lift arms in one place heightwise.
There are several levers on an N. Shift lever, pto lever, draft/position control lever (which you don't have) throttle lever, etc.
The handle you use to raise and lower the implement is called the lift lever or lift handle or Ford called it the "Touch Control" handle.
Is your touch control handle loose? Does it not stay in one place when you set it? It should stay where you set it. If it does not then it can be adjusted or may need a new friction disc to make it stay in one place.
Lastly, if you want position control on a 9/2N you will need to buy a Zane Thang. Very handy device and well worth the money.

PS, Blue tractors run better.

" do I buy the rebuild kit that comes with everything less the chambers or do I buy just the chamber rebuild kit? "

Neither one.

Buy a set of manuals (tip # 39 at the link) Your tractor is operating as it was designed to operate. As others are telling you, it does not have position control. See tip # 58.


" Already has the chains..."

Yea, as UD said, those are called check chains. They keep the lift arms from hitting the tires.

YT sells them too

How much are you going to spend on chains and fooling around with them each time you put the mower on? Just get the ZANE thang and be done with it. I'm not sure what it is going for now, but I spent $100 for the setup and have been very happy with this type of position control on my 2N.

Some even use a chain for their top link. With a
chain, if you were to ever back the rotary cutter up
onto a bank, the chain would give you plenty of
slack and not drive the top link into tractors top
link adjustment area.

Just something to think about.

Hey, stuff happens when you are using a rotary
cutter. It and a chain saw are two very dangerous
machines.

On mine,I put bolts and nuts to set the upper and
lower limits of the"touch control" handle. That
way,I know where the handle should be at full down
as well as full up. This is shown in the
Manual,which you should have as a minimum. They are
sold at Tractor Supply and here on this site.
