Mower Spindel Bearings

Recommended Posts


well I am looking for mower bearings and there is a lot hype!!  some have extra bearing and some have special grease which brings me back to should I install a grease fitting or not.  TIMKEN is suppose to be the best bearing and FARNIR makes the 108202 as P204RR6 and it comes down to price! I really don't want to spend $10.00 and up for a bearing but also don't want to replace bearings every two years. I have 5 decks and it seems like one spindle per deck is always bad.  any new options for us?

I just replaced deck bearings on an old 101.  There is an old Al Eden post regarding greasing these cups that have sealed bearings in them.  I little grease will displace moisture.  As far as bearing longevity goes, My opinion is sharpen & BALANCE your blades at least once per year using a quality balancer like a Magna-Matic.  Not the plastic tree or the old nail trick.  That will make even the cheapest bearings last the longest.

I bought some of the "extra bearing" ones with rubber seals and they didn't fit quite the same as the original bearings (Simplicity used Hoover and Fafnir). This was on a 300/400 Series deck. I should have bought steel shielded bearings. If I recall, it caused some sort of height or clearance issue.

I have cut about 3 acres with my Landlord DLX for the last 7 years, and have done complete rebuilds on the spindles once, and partial rebuilds another time. It always seems to be the bottom bearings that are in the worst shape. It makes sense, they are smaller than the top bearings, are closest to moisture, grit, and so on, and a couple of the housings are a little dogged out. I use the blade on a nail method of balancing, so I wouldn't be surprised that the bottom bearings take more of a beating.  I looked on Amazon for blade balancing tools, but they are either very cheap $5.00 cone type balancers, or $100+ balancers. Not a whole lot in between.

You are correct about the price of a good balancer.  Some say not worth the price.  But when you multiply the price of 6 bearings per deck by multiple decks, $100 isn't that much.  Especially if you pay to have your blades sharpened & balanced.  Some places around me charge $10 per blade depending on how much grass are on them.  Balancing is critical.  @BLT can vouch for that & the Magna Matic Balancers.

BTW, I've never had a Simplicity deck that had different sized bearings on the spindles.  I had no idea the DLX had different bearing sizes on the spindles.

I have used a cone balancer for years, also.Have a buddy with the high dollar tool, so I checked for giggles last year. Seems I have been doing it right for about 50 years.

I cut about an acre of grass, and a half acre in the woods, grinding up anything that fits under the deck..sticks, dead vines that finally fell out of the trees, small trees that come up every year, underbrush, etc. The last set of bearings on the deck were SKF, when I learned that the bearings from the dealer were made in the not so great state of CHINA. I changed those yearly, made an investment at Motion Industries for good bearings. One set died last year after only 10 years of service. The drive (Center) spindle bottom bearing went south. Considering labor, aggravation and cost, the extra cost was and will be well worth the trouble and expense

      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
