Robot mower's front wheel does not swivel or rotate freely, causing poor turning and scuffing.

Safety first: Turn OFF the mower and remove the battery before working underneath.

• Remove caster wheel: Take out the retaining pin or bolt holding the front wheel and remove the wheel from the fork.
• Clean thoroughly: Remove all grass, mud, and debris from the wheel hub and fork using a brush and water (dry thoroughly afterward).
• Inspect for rust or bending: If the axle is rusted, clean it with fine sandpaper and apply a light waterproof grease. Replace if badly pitted or bent.
• Reassemble and test: Refit the wheel and ensure it spins and swivels freely.

When to replace: Replace the caster wheel assembly if it remains stiff or damaged.
