Cutting Height Adjustment

Adjust cutting height using levers on each wheel. Recommended heights: 2-3 inches for most grasses, 3-4 inches during hot/dry conditions.

Mowing Patterns

Alternate mowing direction each time to prevent grass from leaning in one direction. Overlap each pass by 2-3 inches for even cutting.

Slope Mowing

Mow across slopes, not up and down. Use extreme caution on inclines over 15 degrees. Do not mow wet grass on slopes.

Cutting Techniques

Regular Maintenance

Mow when grass reaches 1/3 higher than desired height. Never remove more than 1/3 of grass blade at once.

Mulching

Install mulching plug for nutrient recycling. Best for dry conditions and frequent mowing.

Bagging

Use collection bag for wet grass or when clippings are excessive. Empty bag when 2/3 full.

Side Discharge

For tall or wet grass. Direct discharge away from buildings, roads, and people.
