| One thing I need to improve if I can is the lift on the main boom. I think the tractor hyd. pressure is ok but it will not lift the boom to well unless I have the deck tucked under closer to the tractor. The manal shows different pressures for each of the three valves. Is there a needle valve to adjust those pressures up. We are feeding the main stack of valves from a "power beyond" fitting in one of the SCV valves on a 4230 JD. It has a small throttle valve ( which is full open) in line to the mower valve . It might be that I have good pressure but not much flow because of this. Any suggestions?? Thanks | |
