2200 hydraulics

6011Artist · Feb 21, 2009

My 2200 has been sitting for 5 yrs. I drained all the fluids out, let it sit with plugs out for 4 days. Today I replaced all fluids and it started right up, still runs great, just like it did prior to parking it. The only problem I see is the hydraulic arms won't go back down. I did not pay any attention to them when I started the tractor, was getting the air out of the fuel lines and after it started to run smooth I noticed they were in the fully raised position but the lever was in the normal height position, about a fourth of the way in the raise position. I can push the lever to the lower position and stand on the arms but arms still remain in the highest position. What do I need to do to get the relief I need inside the hydraulic system?

I did not clean the filter, I guess in hind sight I should have. Hydraulics worked normal when I parked it, but has something stuck while sitting and how do I correct it?

Also, there was some water in fluid when I drained it but not a major amount.

The turn screw on the front of the hydraulic reservoir turns, I have tried turning it all the way in each direction to get it to lower. If my memory is right, that controls how fast the fluid moves when raising and lowering implements. Am I right about this? I am more familiar with my Ferguson 35 but will have to get familiar with the 2200 as well.

A big thanks to you guys in advance and also for all the previous help I have gotten here. It helps us mechanically inclined guys save a ton of money on repairs.

With all the hyd fluid. drained out . Mabe moisture in the system & some rust has the piston stuck. Does you'er tractor have the knob in front of the seat that locks the hydraulics in place ?

No knob, just a turn screw that adjusts the speed that the emplement raises or lowers, I think thats how it works.

Also, fluid was not out for 5 yrs, only 4 days.

I am not sure with the setup you have but this may help. Under the seat do you have a valve that looks similar to this see attachment. If so this is what controls the lift.The plunger to lift or raise pushes in to lower comes out it moves the hyd valve inside and may be stuck in.Make sure the Knob you think controls the flo is open that is the HYD. lock out 3pt will not move either way with it shut.There is a parts diagram for this valve on hoye website under ym 2ooo chassis parts. Three point control. It might not even be close to what you have but should be somewhat similar or may get you pointed in the right direction.

After reading Kens post about knob, I went back out to shop and double checked. It does have a second control. It is a lever that is only designed to turn a 1/4 turn, has stops to prevent it from turning farther. Someone explain to me what these two controls do, how they work, what their intended use is.

Carey, I suspect you are right, something is stuck from sitting in water most probably. Was hoping to find a quick fix from someone that has played this game before.

I have a parts breakdown on CD. Guess I will research and see whats in there, maybe figure out what could be stuck or what it takes to get it to move.

If someone with more knowledge chimes in, all help is appreciated.

does it look like the lever on the side of that control that carey posted ? If so that should be the drop rate control lever...Find the 3 pt. lock knod/lever & make sure it's open

After taking hydraulic unit off of tractor and removing the front cover to get to the goodies I discovered the plunger that activates the valve was frozen up. Got it all freed up. put everything back together and it all works like a top. Thanks everyone for your help.

Surprisingly, the screen was very clean and I assume 30 yrs of sludge wasn't really all that bad. Its all clean now!
