Mowing Grass in the Rain 13 Easy Tips

Why mow lawns in the rain?

With a shop, if you have to shut the doors for a day, it will affect your income but not your workload. You will not have literally twice the amount of customers the next day. With a lawn care business, you actually do.

If you cannot work on a particular day, you will have twice the amount of work to do the following day. You can get rained off (unlike a cleaning business, for example). This makes your business unique, and that is not always a good thing.

Sure, it’s better for the turnover, but it comes at a cost. Your business needs to be flexible enough to handle the ebbs and flows of the weather, and having to mow wet grass is one of those things that we will need to manage. 

How do we deal with mowing grass in the rain? 

You are getting ready for another day of mowing lawns, and you look out the window, and it’s raining.

You now have a choice.

  • Do you go out and cut wet grass in the rain today? 
  • Or do you do something else in the workshop? 
  • Perhaps take the day off. (a slippery slope) no pun intended. 

The option you choose will depend on what kind of schedule you run and whether you have any time available to catch up. This article will cover working with smaller mowers on residential lawns, which is my area of expertise. 

There are three ways of scheduling to help you avoid having to work on days like this, and I will run through them here first. These are all good strategies that I know will work if you run between 1 and 5 vehicles in your lawn care business. 

Always have Saturday available as your backup day – This is a good option. You will need to have something mentioned about it in your employment agreement. We usually write into our contracts that if the guys are rained off during the week and have not completed their 40 hours, they must be available on a Saturday if needed.

Driving a lawn care vehicle on a rainy day.

There are a couple of downsides to this.

  • Some of your workers may play sports or have other commitments on a Saturday so they may be unavailable.
  • The other issue is your customer may not appreciate you turning up on a Saturday afternoon in the middle of a BBQ to mow their lawn.

Work 10-hour days Mon to Thursday and keep Fridays available – This could be a slightly better plan if you’re like me and don’t like working at the Weekends.

There are definitely some upsides to this.

  • You can keep Fridays available for Tree work or gardens and roster the guys for overtime.
  • If you are rained off, you now have a Friday available. The kind of work you would have booked for this day can be moved on without too many issues.
  • You will be doing high-paying work on these days so you will be able to afford it.
  • You will be the most popular lawn care owner in town because your guys will have either three-day weekends or high pay packets.

In Winter, when the days get shorter, the grass is growing less, and you can get through your work a little bit quicker, so this normally works out.

The downside is

  • A 10-hour workday in the lawn care industry can be hard on everyone.
  • Some of our top customers have requested a Friday mow, so the lawn looks good for the weekend. They will have to compromise.

Run your business at 80% capacity – We eventually settled on this option. When I employed people, I put them on a 35-hour workweek, and overtime started if they were required to work over 40 hours.

They began at 7.30 am and were back by 2-2.30 pm. We also had the Saturday work agreement, but we hardly ever used it. When your guys are getting in around 2 p.m., it is effortless to keep on top of the workload if it rains or if someone doesn’t turn up.

Rains coming

Is there something else you can do?

If you are a sole proprietorship and you are not running a huge number of lawns, it may not be that much of an issue. Your rainy day list could involve things like.

  • Do maintenance or take gear in to get it fixed.
  • Having a general cleanup. 
  • Catching up with your paperwork.
  • Working on your website or marketing materials.

There are 101 things you will be doing after-hours anyway, so you can simply swap your time around.

What can your crew do?

However, if you run a crew, you must consider them and what they can do. You can send them out to mow in the rain or give them the day off. We have a rule that everyone turns up at 7:30 a.m. regardless of the weather (if there is a real storm, we will text them by 6:30 a.m. to let them know not to come in). If the rain is not too heavy, the guys will go out as usual, but we have a policy about rainy days.

If they worked in the rain for more than four hours and the rain didn’t stop, they could return to the yard and go home. The time they didn’t work will have to be made up later in the week. It hardly ever rained for a full day, and if it did, then over half a day had already been done, so our catch-up time was minimal. We didn’t make a mess with the wet grass clippings or grass stains, as I had taught the guys how to do it properly and leave it tidy.

I am going to go through these with you now.

Mowing lawns in the rain

13 tips to help you work in the rain.

1. Use a bar blade with a lift fin

You preferably want a bit of lift on the ends of your blade to throw wet grass into the catcher or mulch it a bit better. There are three different kinds of lift blades — high or low lift bar blades and flower blades.

The blades below are mulch bar blades, which I find to be the best blades to use to mow a wet lawn. 

Bar blades with a fin

Then you have the straight bar blade. These blades will only work if the grass is dry. 

Flat bar blades

I found swing blades are not the best mower blade to cut grass when it is wet.

2. Make sure your blades are sharp

You need to use sharp blades on wet days. I usually sharpen my blades every 33 mower hours anyway, but giving them a quick sharpening before mowing after rain doesn’t hurt. The shaper the blade, the easier it is to remove grass. 

3. Raise your blade

Cut a bit higher than usual. Cutting high will improve the look of the job. When it’s time to cut the grass, you can always take the height down again on the next visit. 

4. Go slower than usual

Sometimes, you are going to need to do this. If you travel slower with the mower, the engine will not have to work so hard, and it will throw grass into your catcher more easily. It will also help you avoid an uneven cut. You can speed up in areas where the going is a bit easier.

If you step on the grass and the water comes up around your boot, it’s too wet – It is going to clog your mower, and you are going to leave trails. Areas like this are uncommon, but if over 50% of the lawn is like this, it may be best to leave it. Now, if the customer doesn’t mind wheel marks, you could go ahead and mow it high. The wheel marks will disappear over the next week or so. 

5. Use a string trimmer on smaller flooded areas

If a small area is underwater and cannot be cut with a lawnmower, then a line trimmer is a good option. A line trimmer is a better choice than leaving the area uncut. You do need to be careful of where you stand when you do this, as you will leave footprints, so try to keep your foot movement to a minimum.

6. Use a hover mower

This works better when you are a solo operator. When I mowed lawns from 1987-1999, I lived in a coastal town on a peninsula. 

It was wet a lot, and all the lawn care guys had petrol Flymo’s and regular lawn mowers. Using a Flymo worked well and enabled us to work on wet lawns or rainy days without any significant issues. One thing that we had to watch out for was our footsteps, which could leave muddy footprints. 

My old machines are long gone so I searched online for petrol-powered Flymo’s and could not find any. Possibly, they are not making them anymore. The only option I could find was a Toro HoverPro but these do seem to be quite pricey. I think I used to pay around $600 for a petrol Flymo.  

Hover Mower

The secret there was to minimize your steps, which I’m glad to say does become easier with practice. Hover mowers are mulch mowers only, so if you need to catch, you are out of luck there. I normally get a few seasons out of a Flymo, but this machine seems more durable. i used my machine in both light rain and heavy rain. 

Now, having run a lawn mowing business in Hamilton since 2000, I have not had that issue, so I have not bought a Hover mower since then.

7. Keep the chute clean

A clean chute makes for a clean job. Wet grass tends to clog your chute first.  When you empty the catcher, turn the mower off (wait for the blade to stop moving) and clean out the chute. Sometimes, if there isn’t too much of a build-up, you can clean the chute after every job instead. 

Do keep an eye on the chute, and don’t let the wet clippings clog up the chute completely, as I have found that once this happens, the chute is a lot harder to keep clean for the rest of the day. 

Clean the clumps of wet grass from under the mower – Flip and clean under the mower. If you are running a four-stroke mower (and most of us are), never tip it on its side. When cleaning under the mower deck, the spark plug needs to point towards the sky. 

When I am catching, I usually push the mower handle to the ground and weigh it down with a half-full catcher. Doing this gives me easy access to the underneath of the mower, where the wet grass tends to clump. I prefer to wear gloves when cleaning under a mower but that is not necessary. 

8. Only mow your regular lawns

Do not attack any overgrown lawns on a rainy day. You will just find yourself working harder and making a big mess. It’s ok to mow lawns that are regular bookings, but I would stay away from doing any one-off or overgrown jobs.

9. Try short, wet-weather pants.

It sounds silly, but I find I can work harder longer if I wear a rain jacket and shorts. Rain pants can be a pain, and I have yet to find a pair I don’t overheat in. 

The other option of jeans and a rain jacket is even worse. It is incredibly uncomfortable, and you really can feel it dragging on you by the end of the day.

I have been taking a pair of wet-weather pants and cutting them into shorts. Or I guess you could just get a pair on Amazon. This works really well if you’re wearing shorts anyway, and it takes a lot longer before you begin to overheat. You do get that with shorts.

I should also mention that I wear waterproof sock protectors, so my socks don’t get wet.

Nothing worse than wet feet.

10. Have two raincoats and rotate them

I have a coat hanger in my van where I hang one jacket out to dry while I wear the other. After a few lawns, I rotate them. If there is a dry spell, I hang it to dry on my side mirror to dry a bit while I mow a lawn.

11. Start your mower on the grass

Do not start your lawn mower on concrete. That is a terrible idea, as it can leave a nasty green ring on a piece of white concrete. These do not wash off easily and can take a few days to disappear — every time your customers see that green ring; they will wonder why you were cutting grass in the rain. 

Remember to turn your mower off before running over a path or driveway, as grass clippings can also stain the paths. If you have a path separating two pieces of lawn, then do not mow across it every time you pass. Mow one side of the path and then the other. It looks much better than a path with many green stripes.

12. Lift the mower and travel on the back (or front) wheels when moving on paths and driveways

If your back wheels are a mess and your front wheels look clean (or vice versa)  then turn off the mower and lift the back wheels off the ground before heading back to your vehicle. This will prevent you from leaving those horrible green wheel marks across your customer’s paths and driveway.

13. Tap your catcher regularly when you use your mower on wet grass.  

When you have finished taping the catcher, the grass drops back into the catcher instead of falling out in clumps as you push your lawnmower back to your vehicle.

Hopefully, after reading this, you will manage a bit better if you have to work in the rain.


Should I wait until the grass is dry before mowing?

You can wait until the grass is dry before mowing, which will cause you to run behind. Dry grass is easier to cut, resulting in a cleaner, more even appearance. It also reduces the risk of damaging the grass or your mower.

Is there a specific time to mow your lawn in the morning?

There isn’t a specific time to cut grass in the morning, as it depends on your preference and your area’s climate. However, mowing the lawn after the morning dew has evaporated and the grass is dry is generally recommended.

Is it safe to use an electric mower on wet grass?

No, using an electric mower on wet grass is unsafe. Wet conditions increase the risk of electric shock. It’s best to wait until the grass is dry before using an electric mower.

Summing up this post

So, to sum up this post, if you’ve got a yard with damp grass, you must mow it carefully. The thing is, when the grass is wet, it can be a real pain to cut. Wet grass can clog up your mower and leave clumps of grass everywhere. if your grass is wet or even slightly wet, you will need to have a plan of attack worked out in advance. 

Lastly, one thing that I would recommend, and it will make your work life a bit better, is putting on a good audiobook while you work. These are great because while you are working with your wet weather gear on while listening to a good story, it’s like you are somewhere else. I use Scribd for this. It is less than half the price of Amazon, and you get unlimited audiobooks. Go here for a free two-month trial
