MULCHING TIPS

For best mulching quality, follow these tips:

1. Mow at full throttle.
2. Mow at half speed.
3. Mow dry grass only. Mowing wet grass causes clumping.
4. Keep mower blades sharp.
5. Cut no more than 1 in. (2.5 cm) at a time. For tall grass, mow at a higher cutting height, then make a second (or third) pass with the deck set to the desired cutting height.
6. Clean the underside of deck after each mowing.

IMPORTANT: When cleaning, DO NOT wash with highpressure water. Allow all parts to cool before cleaning.
