Keep in mind most of the time if the spindles on the deck have grease zerks, they are sealed bearings. I've seen this on at least 4 different decks from different manufactures. No idea why the heck they do this..
Just pump the cavity full of grease slowly and it will fill the cavity, bypass the seal, and fresh lube is in. 1 or 2 pumps regularly and you wont change another hub.
