Understanding the Hydraulics

F15DOC · Apr 24, 2009

So I just completed my 50 hour service:
engine oil change, engine oil filter change, HST filter change, Hydraulic filter change.
All else is good: greasing, engine system start, clutch, fuel line.

My question is regarding my front loader. Does that hydraulic system run off the HST system? Does it have a separate maintenance schedule?
I have the dealer installed LA series frontloader btw.

Appreciate any insight.

I guess that does matter

I have a Kubota Grand L3240 with LA724 Front Loader

Your hydraulics work off of a hydraulic pump which is attached and driven from the back of the fuel injection pump. You will see two sections to this pump, the larger for tractor hydraulics and the smaller for the power steering.
