Ferris zero turn mower

Anyone got any 1st hand experience with these mowers. I'm needing to re-pack the front wheel bearings as part of the normal maintanence, and looking for some 1st hand experience or a good how to. It appears to be similar to a spindle set up somewhat similarto what's on a boat trailer, but not sure and don't want to go too far without knowing what I'm getting into. Will I have to remove the bottom seal to get the job done ??

What model do you have? Not sure if yours will be the same as my IS-2000 Reason I ask my wheel bearings have grease fittings to grease that. Now the spindles can be packed? You do those the same as your talking about.
