Lawn Care & Mowing Information GENERAL INFORMATION • • • • • • • Proper mowing is an important part of maintaining your lawn in the best possible condition. A healthy and well maintained lawn is better able to resist drought, weeds, and other stresses. But too much maintenance is as detrimental to your lawn as neglect. Proper care for your lawn involves more than just “cutting the grass.
Lawn Care & Mowing Information HOW HIGH TO MOW THE GRASS Cut less than 1/3 Often cutting height is a matter of personal preference. Typically, you should mow the grass when it is is between three and five inches high. The proper cutting height range for a specific lawn will depend upon several factors, including the type of grass, the amount of rainfall, the prevailing temperature, and the lawn’s overall condition.
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: l Mow when the grass is between three and five inches high. l 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.
Lawn Care & Mowing Information MOWING METHODS Proper Broadcast Mowing Broadcasting, or side-discharging, disperses fine clippings evenly over the entire lawn. Many golf courses use this method. Your mower has a deep dish deck to allow freer circulation of clippings so they are broadcast evenly over the lawn. ENGINE SPEED & GROUND SPEED FOR BROADCASTING Always operate the engine at full throttle when mowing.
Lawn Care & Mowing Information TIPS On Dealing With Clippings Clippings are beneficial to your lawn. A common misconception about clippings is that they automatically lead to thatch—this is untrue.
Lawn Care & Mowing Information SOLUTIONS FOR COMMON MOWING PROBLEMS ;;;;;;;;; ; ;; ;;;;;;;;; ; ;; ;;;;;;;;; ; ;; Streaking Streaking Streaking is when thin strips of uncut grass are left behind the mower. Streaking is usually caused by operator error or poor blade maintenance.
