Just in case no one's had the need to get into a spindle... On my Ferris and my SZs both had greasable spindles and what they boiled down to was it allows you to shoot grease into the dead space between the bearings to keep moisture and rust at bay. They are not to actually grease the bearings. Hustler manual says on 3-5 pumps per season IIRK. When opened up so you can see the size of the cavity in there it would take almost a full grease cartridge to fill it's void prior to anything being possibly forced into a bearing. FWIW I'll take a sealed bearing any day over a greasable.
