Yes this is a gas tractor so use a good 10w30, 10w40 engine oil, whatever brand you prefer. Your transmission and hydraulics are separate so use any one of these - JD type 303, Universal tractor fluid, Aw46 tractor hydraulic oil or the equivalent in your hydraulic reservoir under the seat. Check the level on the left side thru the sight guage on the older models or the level plug on the later models. Your transmission uses 80w90 gear oil and the level plug is on left side by your foot when it iis not on the clutch. I sell parts and manuals for your tractor that will help you with all of this. The illustrations are very clear and the quality is excellent. Call 800-609-5110 Bill Rodgers
