| .... your regulated pressure is low on your tractor. Very common problem to see on this vintage of tractors as they are getting up there in age,
First off, regulated pressure is the pressure that moves the spools in those remote valves. Think of it as pilot pressure. When you stroke a remote valve, the solenoids on each end of the valve control the movement of the spool with regulated pressure-if the pressure is low, spools don't move like they should, causing numerous problems with remote valves on those tractors.
The solution is to check/adjust regulated pressure. Should be 290-300 psi with hot oil(above 120 degrees F). Then once you do this, you will need to calibrate the remote valves.
Why did switching your hoses around fix the problem? With low regulated pressure, when you went to push the lever ahead to lower(in your case "raise") the implement, your spool in the valve overshot into float position-which is common, especially if you have your remote valve flow set at 100%. | |
