The manual for the X500 is a bit confusing in the area of deck lubrication. They show the following information (54-inch shown but 48-inch info is the same)
The second bullet, I cannot locate any such cap on my deck idler pivot.
So I checked the parts listing. They show two deck assemblies, one -030000 and one 030001-. If I am interpreting the parts list correctly, the older deck has the idler pivot that needs lubricating whereas the newer deck does not.
Is there somewhere on the deck where the serial number is listed? Why would JD continue to list ONLY the lubrication instructions for the old deck in the 2014 manual and no mention of the newer deck?
