Can you mow wet grass?

Generally, you should steer clear of mowing grass soon after it has rained. This shouldn’t be a problem for domestic users, who may simply need to put up with a more unruly garden for a few days. Landscapers, on the other hand, may find this harder to avoid.

The UK is—if you haven’t noticed—a pretty rainy country. If you only have access to your clients’ properties at certain times and on certain days, you may need to bite the bullet and mow while the grass is wet.

Be sure to exercise caution and use common sense when deciding if it’s too damp for safe mowing, however. If it is still raining—particularly if the rain is falling hard and fast—deciding to go ahead could cause more damage than good, leaving you with a mess to clear up once the weather improves.

Precautions for mowing wet grass

Before you get going, here are a few things to bear in mind:

AVOID ELECTRIC MOWERS: Water and electricity aren’t exactly the best of friends. Using an electric mower on damp grass is not only inefficient, it could be extremely dangerous and cause irreparable damage to your machine. Stick to a petrol rotary mower with nice sharp blades.

CLEAR STANDING WATER: If you’re in a hurry to get mowing because of a tight schedule but the water has yet to soak into the soil, you will need to take extra steps to ensure the grass is safe to mow. Use a hose pipe to siphon off excess water before you get started.

ADJUST HEIGHT: Wet grass is tougher and more prone to clumping than dry grass. You want to give your cutting blades the least possible work to do and cut in stages, starting with the highest possible cutting height.

GRASS COLLECTION: Because of the additional weight of wet or damp grass, you’ll need to remember to empty the grass collection box more frequently than usual. This will depend on the size of the grass chute and collection box on your chosen model.
