hi guys just found this sight and although i am not in the green industry any more i still wanted a commercial mower for home. i went cheap and bought a used byers gold 36 with sulky.I have used it for two years with no troubles till now. the spindle has a piece of metal on it that is in a groove along the length of the spindle.this is what attaches to the pulley that is used to drive the blade. This piece of matel has sheared off and I need to fix it. do I need to get a whole new spindle assembly of can i find just that piece that sheared off. Also where do i find parts for this. I did a search and found out about landscaper supply do they still have parts for this mower. thank you for any info.
