Husqvarna Automower Friction Plate bearing replacement - make sure to read description notes.

replacement of the friction plate bearings in Husqvarna automowers. This may be the required fix if you are getting repeated blade fault or blade blocked errors.
Bearings required are 6800-2RS. You must get bearings with double seals. Note, the OEM bearings lasted years. Amazon bearings are cheap. $8 for 8 bearings. However, they only lasted me a couple months at best. Once I burn through all of these I plan to get them from McMaster. They are significantly more expensive, but they do have Stainless steel bearings permanently sealed that are $24 each which I suspect will last years, potentially the rest of the life of this mower.
