Combines How to adjust Hyd press on JD 9600 Combine

[Joe]

all the combines in our area runnng 12 row have or have put on the larger, heavy duty lift cylinder, and usually have added weights to the rear wheels. Do not know of a screw to adjust psi on the hydralics, but their is a system presure releif valve in the valve stack that you could possibly shim up. I don't know if I would do this on my combine, might put more stress on the pump and hoses, etc.

you have to have the bigger lift cylinders do not mess with the relief valve as you can start blowing hoses and valves apart or the hydraulic pump will come apart
