We’ve all been there. You’ve planned to get the lawns done on Saturday morning, only for a classic Kiwi downpour to strike. By the time the sun peeks out, the grass is lush, growing fast, and most importantly, soaking wet.
A common question for homeowners:
Can you mow wet grass, or should you wait?While it’s always tempting to tick it off the to-do list, mowing a damp lawn requires a bit more care than a dry one. Here is everything you need to know about how to mow your lawn after rain in NZ without damaging your turf or your mower.
Should You Mow Wet Grass?
The short answer is: It’s better to wait. If you can hold off for 24–48 hours of dry weather, your lawn will thank you.
When grass is wet, the blades are heavy and prone to bending. Instead of a clean, sharp snip, your mower blades are more likely to tear the grass. This leaves the plant vulnerable to diseases, which thrive in our humid NZ climate. Furthermore, wet clippings tend to clump together, which can smother your lawn and lead to “dead spots.”
Top Tips for Mowing a Wet Lawn
If the rain just won’t stop and you absolutely must mow, follow these tips for mowing a wet lawn to minimise the risk:
- Raise the Mower Deck
This is the golden rule. Set your Cub Cadet’s cutting height higher than usual. Cutting long, wet grass too short (scalping) puts immense stress on the root system. Aim to take off only the top third of the grass blade. - Check Your Blade Sharpness
Wet grass is tougher to cut than dry grass. Ensure your blades are sharp; a dull blade will pull at the wet roots, potentially ripping patches of grass out of the water-logged soil. - Side Discharge, Don’t Mulch
Mulching wet grass is a recipe for a clogged mower deck. Wet clippings are heavy and sticky; they will clump inside the deck and drop onto the lawn in thick “slugs.” Use the side discharge function to spread the clippings more evenly. - Watch Your Traction
In New Zealand, many of our properties are on slopes or uneven terrain. Wet grass is incredibly slippery. If you are using a ride-on mower or a zero-turn, be extra cautious on inclines to avoid sliding, which can be dangerous and tear up the turf. - Clean the Mower Immediately
Wet grass acts like wet cement. Once it dries inside your mower deck, it’s a nightmare to remove and can lead to rust or corrosion. After you finish, hose down the underside of the deck (once the engine is off and cool) to keep your Cub Cadet in top condition.
How Long Should You Wait After Rain?
In the height of a Kiwi summer, a lawn might dry out in a few hours. However, during the shoulder seasons, we recommend waiting at least one full day of sunshine before heading out. If the ground feels “squelchy” underfoot, it’s too wet—mowing on soggy soil leads to rutting and soil compaction.
While you can mow a damp lawn if you’re careful, patience is usually rewarded with a healthier, greener yard. If you’re looking for a machine that can handle the rigours of New Zealand conditions, find a Cub Cadet dealer near you.
