Rhino FA513 finish mower

[fergy30]

Bought one used and dealer says there are threaded zerks at top end of blade spindles. Mine has none and the hole there is about 3/16" and tapers down inside to about 1/16", maybe 3/8" into the shaft --- no threads. Due to taper can't use drive in zerks either. Has anyone else ran into this...don't know what year it was mfg. or if there was some design change.

Since it's used, maybe somebody replaced them at some point.

doesn't answer your zero question though. Can you use a needle point on the grease gun to get some grease in them?
