  • Gloves
  • Mower

  6. You can wait till the next day to mow the clippings so that it’s spread evenly on the lawn or you can rake the grass clippings away from the lawn.

Mowing Tips

  • Avoid mowing while it’s raining heavily. The water can harm the electrical and mechanical parts of the lawn mower.
  • Make sure you have very sharp blades to mow the lawn, especially after it had rained. Mowing with blunt blades will only add more stress to you. You can order for blade-sharpening kits online or take the mower to a repairer to help sharpen the  blades.
  • Remove the grasses that gets stuck beneath the mower after mowing. Buildup of grasses can cause the motor to stop functioning.
  • If the lawn is wet and hilly, ensure you wear boots that are designed with gripping soles, so that you don’t slip.
  • Don’t overfill your mower with fuel. Use fuel that is enough for a couple of days or a week. Ethanol loves moisture, which can affect mowing.
  • Mow more during raining seasons. There is an increase in grass growth during this period, so it’s only natural that you mow often. Mowing often will give tall grasses no chance because you must have cut it when it was younger.
  • Put the side-discharge vent in place to contain your mowed grass.


It’s safe to say that you can cut wet grasses a few hours after the rain had stopped, unless it was a flooding rain. Overly wet grasses should be avoided and make sure you don’t use electric mower to cut extremely wet grasses. Clean your lawn mower after use to prolong it’s lifespan and ensure better cuts when next you use it.
