PJ - How do you know when a blade spindle goes bad? On my 60" Super Z the 2 outside spindles are tight and when I grease them the grease comes out of the "overflow" hole just above the grease zert when full. The middle spindle seems a little looser but not bad. When I grease this spindle the grease comes out around the spindle when it's full, not out of the "overflow" hole. Is there an indication on performance when the spindle goes out? Mowing quality go down?
