Mower body feels loose; excessive vibration and rattling during operation.

Safety first: Turn OFF and disconnect power before tightening any fasteners.

• Inspect chassis screws: Check all visible screws and bolts on the top cover, side panels, and underside. Tighten to manufacturer torque where specified.
• Check deck mounts: Ensure the cutting deck is firmly attached and that any rubber mounts or bushings are intact.
• Look for cracks: Examine plastic mounting points for stress cracks or breaks. Replace damaged housings or brackets.
• Test run: After tightening, run the mower briefly and listen for remaining rattles to pinpoint any remaining loose parts.
