Mowing Instructions

For best results, follow these mowing practices.

  1. Mow when grass is dry for cleanest cut.
  2. Overlap each pass by 2-3 inches for even cutting.
  3. Vary mowing pattern weekly to prevent ruts.
  4. On slopes, mow up and down, not across.
  5. Adjust cutting height based on season and grass type.
  6. Use slower speed in rough terrain.

Tip: Engage blades only when deck is clear of obstacles. Disengage when crossing driveways or gravel.
