Mowing wet grass

Cutting your lawn when it’s wet is never recommended if you plan on using an electric lawnmower. As the saying goes: water and electricity never mix! Apart from the obvious safety concerns regarding grass becoming slippery when wet, especially when cutting banks or slopes, mowing your lawn when it is wet can also damage your lawn and prevent it from looking neat and tidy.

Most homeowners in the UK like to collect the grass and dispose of the clippings as they cut the lawn, however when cutting the lawn when it’s wet provides a large challenge for most lawnmowers. 

Most typical lawnmowers collect the grass by first cutting the grass with a blade, then by vacuuming it up from the ground in quick succession. Wet grass makes this very difficult, as it is much heavier than dry grass. This prevents the grass from being collected efficiently, and often leads to grass being left on the ground which then requires the user to go around and rake up the left over grass clippings from the lawn or blocking the underside of the deck or grass chute. 

Wet grass is also more likely to clump. It sticks together more easily, again making it difficult for the lawnmower to propel the grass into the collection box. As it sticks together it can then clump around the collection box inlets, which then prevents grass from entering. This again results in more grass being left on the lawn leaving the garden looking untidy. 

If you plan on adding stripes to your lawn then you will need to use a lawnmower with a roller. This adds another risk into the equation when mowing your lawn – soil compaction. The heavy roller which flattens the grass to create the stripes can cause the spaces between the wet soil particles to become smaller, preventing essential water and oxygen from reaching the grass roots, preventing healthy grass growth. 

Cutting the lawn when the grass is wet can also mean your lawnmower rips or tears the grass from the ground, rather than neatly cutting the tip of the grass blade. This can not only prevent your lawn from looking neat and tidy, but in extreme cases it can also overly stress your grass causing it to turn yellow until it has recovered from the stress. 

However if you do cut your lawn when it is wet, then there are a couple of important points to remember. 

We recommend you: avoid operating your lawnmower in wet grass where feasible. Always wear substantial footwear and long trousers and do not operate the lawnmower when barefoot or wearing sandals. 

It more important than ever to make sure your lawnmowers blade is sharp to ensure the grass is cut cleanly and quickly. It is recommended that you change your lawnmower blade at the start of each grass cutting season as a matter of course as part of your basic lawnmower maintenance. 

You will also need to clean your lawnmower much more thoroughly than cutting in dry conditions. Wet grass will stick the underside of your lawnmower much more easily, therefore you will need to scrape any grass clippings from the underside of the lawnmower off and clean out all the air inlets and filters. Before doing this you should ensure the lawnmower is disconnected from the mains electricity supply.

Failure to remove this grass may result in reduced performance of your lawnmower when you go to use it next time, when the grass has dried.
