deck bearing greasing

Recommended Posts


after 19 seasons of mowing and no deck problems, i was thinking of replacing

the bearings. friend of mine had just changed his dads and said they are sealed.

the question here is- 1--if this is true, why the heck have i been greasing the arbors

every few weeks since it was new? and is it true that they are sealed? every one still

seem to be in great shape. i have the 44" deck under my dlx. thanks for any info. --irv

I'm not convinced that OEM bearings in a greasable spindle are totally sealed.

“Sealed” in this case means the bearing isn’t open but has a shield;  and as @Bill725 said above, I believe grease can be forced into them, but not easily.  “Oil” residue from the grease definitely can drain into the lower bearing, but not the upper one.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
