There are quite a few reasons why rain gives grass the upper hand when you try to mow. Grass behaves like people when it’s getting rained on: it hunches over. The result is that many blades of grass get pushed over, not cut, leaving you with an uneven cut not to mention a huge mess. Try to hold off on lawn maitenance when the grass is wet. At least until the sun comes up, when all of the uncut grass should stand back up.
- Some of the wet grass can stick to the mower blades, making it cut less efficiently
- Wet grass can stick also to the mower’s undercarriage. Eventually it will get thick enough to impede the mower blades and slow their rotation, further diminishing the mower’s cutting ability.
- Most mowers have mulching blades that create suction. Cut grass gets sucked up and cut into tiny pieces when it’s dry. But when it’s wet, the grass clumps up and doesn’t get mulched. If left in your yard, clumps of grass larger than the diameter of a tennis ball can weigh down and kill the grass underneath them in a matter of days, leaving you with dead patches.
