If the relief valve worked good in other tractor then it is not the problem. Not necessary to have exact pressure rated relief valve, either one will work up to their rated pressure. Couple other things that happen in those models, make darn sure your not raising the hitch with the draft control lever and have the position control lever too far down in lower position. That last offset portion of the position control is action control.

Just have to put one aux valve on demand and apply air pressure and listen for leaks inside. Too late now but. Anyway.

Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
