3020 syncro hydraulics

On the latter 3020/4020/4320's, the PTO valve is one of the first places suspect of internal leakage,followed by the SCV's,, when you have leakage your stand-by oil supply drops near immediately after you depress the clutch pedal on sychro range tractors,,to sort it out plug off one unit at a time to find which one is suspect,,and if you have a weak transmission pump that will add to the issue,,if you have an after market loader valve be sure to prove it also,,most of them have their own pressure control valve,,they need to be seated tight,,most are set for 1800psi,,you will be pushing 2250 psi to it so it will be popping off all day long
