Actually this is great news because, until yesterday, I thought it was caused by too much knitting. There can never be too much knitting.
The skies dumped about 15” of snow on us yesterday and I did the first pass with the snow blower (thrower)? I squeezed the drive control, muscled it into a u-turn and there was that pain. Must have happened the last time I used it mid-January.
Then the wheels seized. Now I am up to my thumbs and elbows in gear grease from disassembling the drive train to get to a broken bearing. I needed a rest anyway.
