Bobcat m600 change hydraulic fluid

[fatjay]

I have a m600 skid steer. The hydraulic fluid is badly contaminated with water, and I want to change it out. There are holes on the side for drain/fill but there's still af ew gallons at the lowest hole, plus what's in the cylinders and lines. What's the best way to drain the system as much as possible? Siphon pump?

The two plugs between the tires are level checks, there should be a drain plug behind the rear wheel. Since the cylinders are double acting and will have vacuum, there is no way to drain them or the lines without dissembling everything.

Is the drain plug behind the rear wheel at the lowest point? I read to drain i want to lift it backwards with the bucket but i thought that there would still be fluid in it.
