OK I'm brand new to this so have mercy. Just bought a used L3400DT (only 51hrs) and I've never owned anything bigger than a lawn tractor!

I'm confused about references to the Hydrolic system which I assume is the PTO, loader etc. and the transmission which us the gearing. Kubota refers to Hydrolic oil and transmission oil but in the manual there only seems to be transmission oil checks and changes. There is a Hydrolic filter but you change it when you change the transmission oil. So are the two systems the same thing? If not, where is the Hydrolic system check/fill.

I was already confused when I changed the engine oil and filter since there appears to be two oil fill points one in the side of the engine and one on the top(which I used) but the manual only refers to the one on the side.

I'd appreciate any advice and clarification. I'm usually not this confused with machinery!
