I have an S240 with 72 hours on it and I always log when I grease the deck, mower,change oil, etc., However, when I follow the periodic maintenance sheet from JD it shows a wheel hub grease fitting on both front wheels, on the inside of the wheel as I always had on my LA140, 145, etc. There seem to be none on this machine. I apparently assumed when I greased the machine previously that there were none and JD no longer thinks they are necessary. Am I starting to lose it in my old age or am I going blind and unable to see them anymore. All other grease spots/fittings are as shown in the manual and the two wheel hub fittings are also shown to be greased---but there are none on my machine. What gives?
