Robot lawnmower front caster wheel does not rotate freely, causing drag marks and navigation issues.

Safety first: Turn OFF the mower and lift the front end onto a stable surface.

• Remove debris: Pull out grass and mud from around the caster wheel and fork.
• Spin test: Rotate the caster by hand. If stiff, remove the wheel according to the manual.
• Clean and lubricate: Clean the axle and bearing surfaces, then apply a light, outdoor‑safe lubricant.
• Replace if needed: If the wheel still binds or wobbles excessively, install a new caster wheel assembly.

A free‑spinning caster is essential for accurate navigation and reduced turf damage.
