I have a 1990 John Deere model 170 garden tractor - 18 HP Kohler motor w 38 inch deck.
About to replace disc brake pads and need to remove right rear tire for access.
Rim has no mounting bolts showing, just a 2 inch plastic cap in the center - removing plastic cap shows snap ring.
Back of rim extends 4 - 5 inches oveer shaft to transaxel housing - no sign of bolt through rim/axel or of key.
Any hints on removing tire/rim from axel?
Thanks,
Pete
