Mower wheels spin but the mower barely moves or slips frequently, especially on slopes.

Safety first: Turn OFF the mower and disconnect power before handling wheels.

• Inspect wheel tread: Check the rubber or plastic tread pattern. If lugs are worn down, replace the drive wheels.
• Adjust mowing schedule: Avoid mowing immediately after rain when the lawn is very slippery.
• Limit slope areas: Use boundary wire or no‑go zones to exclude steep slopes beyond the mower’s specification.
• Clean wheels: Remove caked mud or grass from the wheel surfaces to restore grip.
