7130 3 pt need help

[tjiniowa]

Got a 7130 magnum tractor to put on the planter but the 3pt hitch will not quite go all the way down to get the planter level. It will raise it up to transport height but only down just enough to hook up the planter, but in the field the arms a about level when all the way down. Should go lower I have played with all the knobs in the cab.

Unfortunately that's apparently the electrical bug-a-boo on those tractors. Fortunately for me, I don't use the three point on my 7240. But the arms do go all the way up and down. Mine is constantly flashing something on that little screen. My CaseIH mechanic indicates one of the electrical load sensors down on the draft arms is probably bad. If you could get a hold of some service information, maybe you could figure it out.

If it will not go down even with planter hooked up and weight on 3 point you probably have one of the lower limit switchses not all the way down. There is more than one. One under armrest and one you can see on right side also I believe. I will look at mine this morning to check for sure, i have a magnum and NH that are very similar. Good luck.

My Ford 8240 would do something similar. If I had the rate of lower set to a slow drop and pushed the lift control down too fast to the point where the control got too far ahead of the arms, it would go down just so far and stop. If I lifted it back up, and pushed the lever down slowly it would go all the way.

I agree with hydro 70 guy - there should be a fault code flashing on the panel where the knobs are.It would point to what sensor may be at fault.Someone here may have a manual to interrupt the code,or the fault tree to troubleshoot it.Mark

The single most usual problem with a hitch on those models of Magnums, that won't respond full down or up is the potentionemeter on the right rear of the rock shaft. They get rusted up and just plain out of wack. They are pretty much exposed to the elements.

Caution though, as playing with that switch with engine running can be extremely dangerous. They are to be set with instruments hooked up to the hitch controller but a experienced mechanic (on that system) can adjust them without that tool.

I heard of one guy getting crushed on a similar style electronic hitch that Case used.

I found both sensors were unplugged by the previous owner I don't need draft in trouble I just want to get the three-point to go down some more. There is a trouble code of an S.

 

[tjiniowa]

Can I disconnect that potentiometer and operate manually

S code is for the draft pins failed. Will not cause your problem.

No.The controller is looking to match the hitch position potentiometer signal reading to the desired setting from the position control potentiometer. Disconnecting either sensor will default the system to a halt condition.

As Pete 23 already mentioned the position sensor on the rockshaft will often freeze up and slip the lever out of position. The danger with your situation is if you raise the hitch full up and the internal arm is pressing against the cover it can flex and break the casting.

It is the rod adjustment that is giving me problems on the rockshaft. Does anyone know how to properly adjust it?

The problem usually begins when the shaft, item 59, gets dry and dirty and binds in the bushing in the housing, item 58, causing the lever, item 11, to slip out of adjustment.

If you don't have a basic understanding of how the system functions and don't have proper test equipment (DVOM and a back probe) the adjustment can be very dangerous because you'll need to move the adjustment with the engine running and there is very little room to work.
