Grass clumping under a lawnmower when it's wet is a common issue that many lawn care enthusiasts encounter. This problem occurs primarily due to the moisture content of the grass and the conditions during mowing. Here's why it happens and how to reduce it:
Wet grass has a higher moisture content than dry grass, which makes it stickier and easier to clump. Wet grass can clump together as the lawnmower blades cut through it and collect underneath the mower deck.
Size of the Grass Clippings: The size of the grass clippings is also important. The grass clippings are typically longer and heavier when the grass is wet, which increases the likelihood that they may clump together.
Mower blade dullness: Grass is torn rather than smoothly mowed by dull mower blades. When circumstances are damp, this tearing motion might exacerbate clumping.
Follow these recommendations to minimise grass clumping when cutting damp grass:
while feasible, mow the lawn while the grass is completely dry. It is more difficult to make a neat cut with wet grass since it tends to cluster more.
Sharpen Blades: Make sure the lawnmower blades are cutting-edge. The chance of clumping is increased when the grass is torn by dull blades. Replace the blades when necessary or regularly sharpen them.
Raising the mower deck to a higher cutting height will change the mowing height. This improves airflow underneath the mower deck and lessens the possibility of grass clumps forming.
Increased Mowing: If your grass grows quickly, you might want to increase your mowing frequency, particularly in the rainy season. Cutting shorter sections of grass at once can aid in clump prevention.
Consider using a mulching mower, which has special blades that chop grass into smaller pieces and scatter them evenly throughout the lawn.
Reduce Your Speed When Mowing Wet Grass: When cutting wet grass, slow down. As a result, the mower has more time to process and distribute the clippings evenly.
Dry the Grass: Don't mow the grass until it has completely dried out if it is damp from morning dew or a little rain. As an alternative, you can aid in drying the grass before cutting it with a rake or leaf blower.
Clean the Underside of the Deck: To get rid of any stored grass clippings and dirt, periodically clean the underside of your lawnmower deck. This prevents clumping and maintains optimum airflow.
By adhering to these recommendations, you can cut your lawn more neatly and evenly even when the conditions are less than perfect and reduce grass clumping when mowing wet grass.
In no particular order:
No.1 - Blade Type (Wrong Blade)
No.2 - Blade Blunt/Damaged
No.3 - Wet Grass
No.4 - Grass too long
No.5 - Mowing too fast
No.6 - Not using Full Throttle
No.7 - Clean under Deck
I explain these in more detail in the video. I hope they help.
