• For best results, mow when the grass is dry.
• Overlap cutting swaths slightly to ensure even coverage.
• Avoid cutting more than one-third of the grass height at a time. If the grass is very long, make two passes with a higher cutting height first.
• Empty the grass collection box regularly to maintain optimal performance and prevent clogging. The hybrid grass box includes a fill level indicator.
