Mowing Greasing finish mower spindles

[sixdogs]

In all these posts there really is no consensus. I tired to find info on my B7800 mower deck a couple years ago and came up dry so I just grease every other use. But I sure would like to know what is the correct schedule. No mention in the owner's manuals or anything. Beats me but how come it's not addressed. Must be that Roswell thing.
