You should get an owner's manual with it. Expect at least 6. If you can't find anything put in 6 and then add by watching the dip stick. I like to fill the oil filter before installing it...makes for a wet start the first time on the change rather than having to wait for the filter to fill before you get oil on out and into the vital parts. If the front drive line goes directly under the engine crank case, your oil pan may be U shaped and have a drain plug on each side....yellow marked plugs.
Then when you are at the F mark, crank and idle it for a minute or two, shut it off, wait a few minutes and top it off.
The Front axle will be about 2 gal and use gear oil...80-90, or full syn in that range if you want..... if not already specified on the rubber fill/dipstick hootus....probably will have 3 drain plugs...usually painted yellow, left, right and center. Only one fill plug will have the dipstick which serves for both sides when filling....just get on level ground.
The main sump (tranny, hydraulics,hydrostatics, and rear differential all in one) drain is back at/under the differential and yellow too. The fill is on the right rear, topside, orange rubber hootus for a plug. Dipstick is on top of the rear axle, left side on my 6530 and between your feet at the rear of the floorboard on my 2400. Use Premium Universal Tractor Fluid due to the tractors amenities. Fill on that may be about 10 gallons. When you go to change the filter, drain the sump first as the filter plugs directly into the sump and if you pull it all the fluid will drain out.
