   We've been having issues with the roller bearings especially on the rear rollers. I have replaced around 20 sets of bearings this year and thats a bit excessive in my eyes. The mower gets a lot of use (about 800 hrs per season) but I still feel it's too much. Any suggestions on what to try to alleviate the problem. I'm currently only getting about 200 hrs out of a set of bearings.

   Are you finding water and rust inside?

   We've been running them for three years now, and I have always felt the rear rollers were a strong point of the unit. I use Swepco 103 w/moly, and we've hardly had any go bad due to bearing failures. We grease them every Wednesday, but we are using 5 machines for 36+ holes, and one 7400 and mowing everything within two days. I've slowed the mow speed down to 5.5 to 6 mph and that has helped us for sure. We check them for end-play every week and will remove them and adjust the nuts down and remove and play if needed.
   
   Hope this helps,

   My guess is probably the grease you're using. We have 2 8800s with about 2600 hours and we have not replaced any bearings at all. Try something with Moly or this red grease from Kimball Midwest https://www.kimballmidwest.com/All-Prod ... ses/80806/
   
   The way I test any new grease is I put some on a screwdriver, light it with the torch, and if it melts and drips on the floor is not a good sign.

   Don't know about this machine, but I do remember at my last course with a JD fairway (3235B), tee (2500), and bank mower (2653A), we used the recommended John Deere greases, (I remember some of them were corn head grease I guess for combines?) and we didn't see many issues at all.
   
   My current course we use John Deere HD Water Resistant Grease on our equipment which includes a 3235C and 1600 WAM and they seem to be doing well.
