Farmall h

volkswagen · May 30, 2011

I am attempting to bring a Farmall H back to life that was abandoned on my property many years ago. So far I"ve had good success in getting it running and most things seem to work. One problem is that the left front bar does not lift (the right and back one does). I noticed the spring under the cylinder is broken. Would this cause the bar not to lift? Or is the broken spring symtomatic of something in the hydralic system gone bad. There are 3 seperate hoses coming out of the transmission case, each going to one of the 3 bars. If 2 work is it possible for the third not to work? Any advice would be appreciated. Thanks, Jim

Bar? Does it have a cultivator on it? Not really sure what you are looking to do (or talking about)

Anyhow, there is a delayed lift system on your tractor (and every other liftall system) The two pipes across from each other are the ones you want to use for normal stuff. The one that is offset is the delayed lift outlet.

glad you asked. I was wondering what he meant by a bar?

All 3 outlets have equal pressure and flow volume.
If you are talking about the delay lift for the rear gang of a cultivator, the delay lift valve goes in the hydraulic line. It is a spring loaded devise that only opens with a set pressure.

The front gangs do not take a lot of pressure to lift them. After they are up all the way the pressure builds because the cylinders are fully extended and then the delay lift valve opens and the rear gang raises.

I was excited to get replies to my question. I have tried to attach some photos of the left cylinder with the broken spring below. This is the left one which does not elevate. Also shown are the left side in the down position and the right side, which operates correctly, in the up position. By the bar I am refering to the horizontal bar that raises and lowers, to which you would attach some implments (cultivators).
Thank you very much for your help. Blessings, Jim

From what you describe, the broken spring is a counterbalance and that very well could be the problem. To eliminate the possibilities, I'd disconnect the rod of the non-moving cylinder (don't let it fall - block it up) and make sure the cultivator linkage/mechanism isn't in a bind. Then check to see if the cylinder will extend without a load. If it doesn't extend, you may have a plugged or collapsed hose, or the cylinder itself has seized. Being a one-way system, you know the cylinder isn't bypassing or it would be leaking oil.

Are you sure the spring doesn't help the one way cyl retract?
