Avoid mowing wet grass.
Mowing a wet lawn doesn’t harm the grass, but it doesn’t yield the best results. Wet grass fills and clogs a mower deck. It also has a tendency to fall over and clump together as you mow, creating an uneven cut. Watch for clumps of wet grass that fall off the mower. Remove these from the lawn after mowing to avoid killing grass. Always avoid mowing in soggy soil, or you risk creating wheel ruts and tearing up grass. If you must mow the lawn when it’s damp, treat the underside of your mower with oil or silicone spray to help prevent grass from sticking. Also, make sure your mower blade is sharp to avoid ripping grass out of soil. Finally, if you must mow in wet conditions, slow your mowing speed (not the engine speed) to allow the mower the best chances to cut and collect the heavier grass cuttings.
