Wet grass clumps and the clumps lodge in the mower deck, restricting airflow and jamming the blades. Either can strain the engine, causing it to overheat or stall.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">Mowing sticky, wet grass can also dull your mower blades.&nbsp; This means you\u2019ll need to replace or <a href=\"https:\/\/lawnlove.com\/blog\/how-often-sharpen-mower-blades\/\">sharpen the blades<\/a> more often.<\/p>    <p class=\"wp-block-paragraph\">And while it\u2019s tempting to let that built-up grass in your mower deck dry before cleaning, that moisture will seep into the components, eventually rusting them.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"3-presents-safety-hazards\"><span id=\"presents-safety-hazards\">Presents safety hazards<\/span><\/h2>    <p class=\"wp-block-paragraph\">Lawn mowing is a common chore, but it carries some risk. The U.S. Consumer Product Safety Commission estimates that every year, 80,000 people end up in the ER with a lawn <a href=\"https:\/\/lawnlove.com\/blog\/lawn-mower-safety-tips\/\">mower-related injury<\/a>. But mowing on wet grass carries its own risks:<\/p>    <ul class=\"wp-block-list\"> <li>Wet grass is slippery. It can be hard to control the mower and keep your footing, especially on slopes and uneven ground. A fall can send you to the ER with a sprain, a cut, or a devastating injury should you land too close to the mower blade.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>Riding mowers can lose traction on wet grass. A slip or skid could throw you off the mower.<\/li> <\/ul>    <ul class=\"wp-block-list\"> <li>It can be hard to see things in wet grass, especially if it\u2019s high. So, you could hit \u2014 and create a projectile from \u2014 a dog toy, a sprinkler head, or the blade that broke when you hit something.&nbsp;<\/li>    <li>Corded electric mowers come with safety features, but using one to cut wet grass puts you at risk of being burned or shocked if water gets into the electrical connections or a frayed cord touches wet grass.<\/li> <\/ul>    <h2 class=\"wp-block-heading\" id=\"4-clumping-creates-thatch-problems\"><span id=\"clumping-creates-thatch-problems\">Clumping creates thatch problems<\/span><\/h2>    <p class=\"wp-block-paragraph\">It\u2019s hard for a mower to properly cut wet, clumpy grass, so it tends to leave those clumps out on the lawn. If they aren\u2019t removed, they\u2019ll&nbsp; decompose, killing the grass underneath.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">The decomposing clippings and grass will create <a href=\"https:\/\/lawnlove.com\/blog\/what-is-thatch\/\">thatch<\/a> \u2014 a layer of material that builds up on the soil and prevents water and nutrients from coming through.&nbsp;&nbsp;<\/p>    <figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Tip:<\/strong> Purdue University\u2019s Department of Horticulture and Landscape Architecture suggests a couple of things to help prevent thatch buildup:<\/td><\/tr><\/tbody><\/table><\/figure>    <ul class=\"wp-block-list\"> <li>Double-cut the area.

Then, it\u2019s difficult for air, water, and nutrients to reach grass roots, so your lawn will suffer.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">Mowers can also create ruts as they move through the soft soil. This creates other problems: Uneven ground is difficult to mow, and stepping in or tripping over a rut can cause injury. If the ruts are deep, they can hold rainwater, making them a dandy breeding site <a href=\"https:\/\/lawnlove.com\/blog\/how-to-get-rid-of-mosquitoes-in-yard\/\">for mosquitoes<\/a>.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"6-grass-doesn%E2%80%99t-mulch-or-bag-well\"><span id=\"grass-doesnt-mulch-or-bag-well\">Grass doesn\u2019t mulch or bag well<\/span><\/h2>    <p class=\"wp-block-paragraph\">Wet grass can affect the performance of your mulching and bagging mowers:<\/p>    <p class=\"wp-block-paragraph\">Clogging is prevalent with mulching mowers. The wet clumps tend to collect on the mower deck and clog the blades and the discharge port. So, you\u2019ll likely have to interrupt your mowing to clean the deck. Don\u2019t know how? See our article, \u201c<a href=\"https:\/\/lawnlove.com\/blog\/how-to-clean-lawn-mower-deck\/\">How to clean a lawnmower deck<\/a>\u201d.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">That sticky, wet grass will also collect under the deck of your bagging mower, clogging the discharge chute and the bag. Even if clippings make it into the bag, wet grass is heavy, so the added weight will put more strain on the mower; pushing it will put more strain on you.<\/p>    <p class=\"wp-block-paragraph\">If you\u2019re thinking about removing your mower&#8217;s bagging attachment, the University of Missouri Extension urges you to be careful. Many bagging attachments affect mower safety and performance, so consult your owner\u2019s manual first.&nbsp;<\/p>    <h2 class=\"wp-block-heading\" id=\"7-faq\"><span id=\"faq\">FAQ<\/span><\/h2>    <div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1750853175202\"><strong class=\"schema-faq-question\">When can you mow after the rain stops?<\/strong> <p class=\"schema-faq-answer\">A rule of thumb is to wait at least 24 hours before you mow. To be sure, test for dampness by walking across the lawn. If your steps leave visible footprints, it\u2019s still too wet. If the grass springs back up, you\u2019re good to go.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1750853183247\"><strong class=\"schema-faq-question\">What if you must mow wet grass?<\/strong> <p class=\"schema-faq-answer\">For those of us who live with spring deluges, cutting wet grass is better than cutting foot-high grass. To minimize stress on the lawn and your mower:<br\/><br\/>\u25cf Go slow: This reduces clumping and helps the mower cut more evenly.<br\/>\u25cf Raise the mower height: Short cuts increase clumping and damage.\u00a0<br\/>\u25cf Make sure the mower blade is sharp.<br\/>\u25cf Use a side-discharge mower if possible.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1750853200364\"><strong class=\"schema-faq-question\">Can you use a cordless mower to cut wet grass?<\/strong> <p class=\"schema-faq-answer\">Some cordless mowers are water-resistant, but most manufacturers advise against cutting wet grass with their products. For example, owner manuals for both Stihl USA and LawnMaster products specifically say not to do it.\u00a0<br\/><br\/>A cordless mower\u2019s battery and electrical parts aren\u2019t waterproof. So know that if you use a cordless mower on wet grass, you\u2019re risking a short circuit or other major damage.<\/p> <\/div> <\/div>    <h2 class=\"wp-block-heading\" id=\"8-need-mowing-help\"><span id=\"need-mowing-help\">Need mowing help?<\/span><\/h2>    <p class=\"wp-block-paragraph\">If your schedule doesn\u2019t give you time to mow when the grass is dry, Lawn Love can connect you with experienced professionals in your area who can handle your <a href=\"https:\/\/lawnlove.com\/lawn-mowing\">lawn mowing<\/a> needs, as well as <a href=\"https:\/\/lawnlove.com\/weed-control\">weed control<\/a> and <a href=\"https:\/\/lawnlove.com\/lawn-aeration\">lawn aeration<\/a>.<\/p>    <p class=\"wp-block-paragraph\">Main Photo Credit: <a href=\"https:\/\/stock.adobe.com\/images\/lawn-care-green-wet-grass\/248861009\" target=\"_blank\" rel=\"noreferrer noopener\">GAGO IMAGES<\/a> | Adobe Stock<\/p>","protected":false},"excerpt":{"rendered":"<p>There are good reasons not to mow wet grass.
