Lawn Care & Mowing Information

WHEN AND HOW OFTEN TO MOW

The time of day and condition of the grass greatly affect the results you’ll get when mowing. For the best results, follow these guidelines:

Mow when the grass is between 3”-4” (7,5-10 cm) high.

Mow with sharp blades. Short clippings of grass one inch or shorter decompose more quickly than longer blades. Sharp mower blades cut grass cleanly and efficiently, preventing frayed edges which harm the grass.

Mow at time of day when the grass is cool and dry. Late afternoon or early evening often provide these ideal mowing conditions.

Avoid mowing after rain or even heavy dew, and never mulch when the grass is wet (moist grass does not mulch well, and clumps beneath the mower deck).

Note: Always operate the engine at full throttle when mowing.

PROPER MOWING SPEED

ENGINE SPEED & GROUND SPEED

Always operate the engine at full throttle when mowing. If you hear the engine slowing down, you are mowing too fast—maintaining a slower ground speed will improve the cutting efficiency of the blades and prevents many com- mon cutting problems.

Select an appropriate ground speed for the thickness and height of the grass you are cutting (3rd gear or slow- er for manual gear models, or mid-range or slower for hydro models). If you hear the engine slowing down you are mowing too fast, use a slower ground speed.

HOW MUCH GRASS TO CUT OFF

Mow when the grass is 3”-4” inches (7,5-10cm) long. Do not cut off more that 1” (2.5cm) of grass in a single pass.
