Hydraulic pressure

[Dranerb57]

I have a kubota L4330hst with a loader, what is the hydraulic pressure the tractor produces? Its flow is around 9.4 GPM

Welcome to TBN
Since no 4330 owners are coming around yet I'll give you a maybe answer. I am not sure about your specific tractor but from my limited experience all the L series machines I have seen were spec at a 2500 psi factory setting.

Thanks for the info, I called the local kubota service dealer, they just said under 3000 psi

Dranerb57,

The tractor will produce a pressure based on the load on the hyd system.

Relief pressure is set to relieve at a pressure below the pumps max pressure to protect the pump.

A 3000 psi hyd gage is highly recommend to monitor and trouble shoot the hyd system.

J.J. is the gage something I can get at the kubota dealer, graingers, TSC?
