Robot mower occasionally stops with front lifted slightly and wheels spinning, even on small obstacles

Safety: Turn OFF the mower before inspection.

• Inspect front wheel: Lift the front of the mower and spin the caster or roller by hand. It should rotate freely.
• Clean axle: Remove grass, hair, or string wrapped around the axle.
• Check bracket: Ensure the front wheel bracket is not bent and allows full movement.
• Replace if worn: Install a new Makita front wheel or roller assembly if the old one is seized or badly worn.

A properly functioning front support wheel helps the mower ride over small bumps instead of getting hung up.
