I have an 03/04 eXmark viking with those sealed spindle bearings. I've tried to cross reference these bearings to other brands to get a price range but have'nt come up with much. The bearings in there now are Fafnir RA100RR7 E8728. Does anyone know what where to get these bearings or what numbers they cross reference to? Do these bearings come on anyother eXmark mower? based on my searching, it looks like these bearings come on a lazer also?
