lawn mower blades stop spinning

[tomplum]

A word of caution here is that the OP did not post the chassis number from below the seat as far as I see. Though likely a Husqvarna built tractor, it could be an MTD built unit. Parts are different. In either case checking the pulley spline and trueness is a good idea, no key on a deck pulley and no need to worry about a puller.

I replaced the spindle housing and the mower is working well again. I appreciate everyone's input on this forum. Thank you!
