wobbling mower deck?
Blades are new with only a few hours on them and in good shape. Belt is in good shape. I thought it was one of the idler pulleys and decided to replace them all, they are in new condition, but I will double check for a flat spot. No bent spindle, and all bearings seem to be good but how would I know for sure? Everything seems tight, no wobble in any individual bearing or pulley, all blades turn freely by hand. The spring on the idler pulley seems ok but it is old and might have lost some of it's tension, allowing that idler to move more than it should. Could that be it?
Motor runs good and smooth. I thought it might be in the clutch but it is working fine.
