Case IH 1130 Hydraulic Question

John B. · Mar 4, 2018

I got my little 1130 out yesterday and played around mowing the lawn for the first time with it. When I raise the belly mower it comes up then drops half way back down after the hydraulic lever is released. The tractor has dual remote hookups in the back where the lift cylinder is hooked to. The mower's lift cylinder is only using one hose to raise the mower deck. It is a dual acting cylinder but no hose is connected to the lowering side but I think I'm going to add one to keep from dead-heading that circuit when lowering the deck. Any ideas what would cause the deck to drop after I release the lever? Thanks in advance.

Thing is made that way and you are really not as you say dead heading that valve. Changing to a two way valve may require you to change the cylinder. All that being said abut three things could cause what you are experiencing. First and most likely is simply the piston packing in the cylinder has a slow leak and is letting oil pass. Next would most likely be a leak in the control valve last of all air but that should work out. Raise the deck leave the lever up and shut off the tractor see if it goes down. Try to determine if the problem is in the cylinder or the valve.

When I lower the deck, it at the same time sends pressure to the other hose which is not connected to anything so it is dead heading that circuit. At an idle it will kill the engine. I'm not sure why you would say it's not dead heading.
