I got the same tractor minus the cab. It is pretty easy. If you have a FEL I would make sure the cylinders are retracted so as much fluid is in the tractor as possible.
According to the shop manual remove the 4 drain plugs. One under each rear brake, and 2 underneath in the middle line of the tractor. Open the fill plug. I would add also pop off the 2 rubber hoses that connect to the hydro cooler on the front since that is the high point. It is just a couple hose clamps.
When filling preload the filters with some fluid to get them wet and it will get some air out. Don't fill all the way since you have to turn them sideways to install. Keep an eye on the site window in the back. Since it holds 10 gallons it will take a while to fill.
Once filled, run for a several minutes while turning searing end to end a couple times, 3pt up and down a couple times to get the air out and then recheck level. Kinda like changing oil in the engine.
Hope this helps. Let me know and I can scan some pages from the manual for you.
