Replacing deck bearings on a Scotts/Murray riding mower

The idler pulley gave up the ghost and while I had the deck off I noticed there was a good bit of movement in the blade shafts, fair enough since the mower is either 20 or 21 years old.
I got the old bearings out and was surprised to see that they were sealed bearings on the inside, with the outside being shielded. I have always kept it greased and having this ability is one of the main reasons I bought this mower in the first place. Would it not make sense to pull the seal out so the grease can actually get into the bearing?
Or am I just over thinking this?
Thanks guys.

If you keep them pumped full of grease, then pull the seal and keep it greased. Most mowers with grease fittings these days have sealed bearings because probably 1% or less of owners actually keep them greased properly.

I pulled the seals. I was really surprised at how little grease there was in the bearings from the factory. Either it doesn't take much grease to keep them going or these wouldn't last a year.
Thanks for the advice.
