Loud Rattle When The Mower Is Moving.

This is caused by a worn, bent, or loose blade, or a bent engine crankshaft. Replace the blade or tighten the blade bolt. If the problem persists, you'll have to obtain professional service. (For referral, use the contact information here--https://www.contacthelp.com/husqvarna/customer-service.)
