hydraulic fluid reservoir

[bsabill]

My Skid steer pictured has a reservoir below the floor and a small one behind the seat with two hoses going to the hydraulic system. Stupid question, but which one is the reservoir that I'm supposed to fill? If not the one beneath the floor, then what is that for? I'm confused.

Well if its like a Bobcat the lower reservoir is the chaincase, the fluid in it lubricates the drive chains and axle bearings. The upper reservoir should be for the hydrostatic/hydraulic system.

What fluid goes in there , and I assume I should fill about 1/2 way?
