Hi guys and gals. Changing my hydraulic oils on my 1025r. Front axle all done. Transmission oil all drained and ready to fill. I know it calls for 13 quarts, but should I also be able to see the oil when I remove the fill cap or does it sit much lower even when I add 13 quarts? Gonna pour from a 5 gallon bucket. Dont want to have to measure out 13 quarts if I dont need to.
