Best Lawn Mowers for Uneven Ground and Slopes

If you have an uneven or sloped lawn then you may have noticed that certain lawn mowers just don’t cut it. If you choose the wrong mower, mowing a hilly or bumpy lawn can be a nightmare. It can also be dangerous.

To help you choose a mower that’ll tackle those slopes with ease, I’ve put together this guide on the best lawn mowers for uneven ground and slopes. I’ll be showing you some of my top choices as well as giving you some easy to follow advice on selecting a mower and using it on your uneven lawn.

What power type is best for uneven lawns

What Is The Best Power Type For Uneven Lawns

Lawn mowers come in various power types and that’s great because it offers homeowners versatility. However, if you’ve got an uneven lawn or one with a lot of sloped ground then it’s best to stick with either a hover mower or a self propelled model.

Hover mowers don’t have wheels like other types. Hover mowers don’t have wheels. Hover mowers do not have wheels. Instead, they have an air cushion under the deck that makes it easier to maneuver on uneven terrain. What’s more, a hover mower will be able to tackle hills and slopes up to 45 degrees so they’re ideal for this type of work.

A hover mower is also a great choice because of its compact size. While petrol mowers with a self propelled drive are also a great choice, and I’ll talk about those shortly, they’re often very bulky which makes it difficult to mow in tight spots.

So, petrol mowers…these are another brilliant option for uneven lawns or slopes; just make sure that you choose one that’s self propelled. These mowers make a difficult job much easier, which would otherwise be very tiring.

The powerful petrol engine powers the wheels so you don’t need to push the lawn mower up slopes, just guide it in the direction you wish to go. On top of that, this power, which is far greater than anything you’d get with a cordless or electric mower, will make it a lot easier when mowing over rugged ground.

How to Choose a Self-Propelled Lawn Mower

These are the things you should consider when choosing the best self-propelled mower. Let’s cover them now.


Choosing A Self Propelled Lawn Mower

There are cordless self propelled mowers but these aren’t as powerful as petrol so I’d always choose a mower with a robust petrol engine. Generally speaking, you’ll want at least three HP as this will ensure enough power to the blade and will propel the mower forward.

Many petrol lawnmowers are equipped with a variable-speed drive. This allows for you to adjust the self-propelled speed. While you might prefer the mower to move faster on flat ground, it will need to be slower when going up and down hills. This option will greatly simplify mowing and make it safer.


Nobody wants to be lugging around a heavy lawn mower at the best of times, never mind when you’re tackling difficult terrain. Therefore, I would always recommend choosing a mower that’s as lightweight as possible.

Of course, petrol lawn mowers are always going to be heavier than other power types due to the presence of the engine and they’re typically made from steel. However, there are some lighter models out there and this goes a long way in ensuring that the mower doesn’t get stuck. Plus, it’ll be a lot easier to move around.

Rear Wheels

If you’ve read any of my previous guides, you’ll know that I often talk about the lawn mower’s rear wheels. Although it may seem insignificant, this is critical. Rear wheels with larger diameters provide greater stability and maneuverability, especially when driving on rough terrain.

These large wheels will prevent your lawn mower from getting stuck in bumpy or muddy areas. Even in muddy areas, smaller wheels will catch easily.

How to Choose a Hover Mower

Choosing A Hover Mower

Hover mowers are perfect for sloped lawns but as with self propelled models, there’s a couple of things to consider before settling on any particular model.


Hover mowers are powered by electric engines and while they’re not AsPetrol mowers are powerful, but there are other options.

In this case, I’d suggest looking for the most powerful model possible as this will ensure the strongest cushion of air. If you go for something weaker, you’ll find the machine is much more challenging to move up hills.


As I talked about with self propelled mowers, you want to find a hover mower that’s lightweight and easy to work with. These mowers are lighter than others because they have plastic decks. However, you don’t want to go too light as this typically means the mower will be smaller. That’s OK if you have a small lawn but for bigger gardens, it’ll increase the mowing time.

Cutting Width

Cutting width is important when choosing any lawn mower as it’ll determine how long it takes to mow and how easy it is to get into nooks and crannies. If you have an uneven lawn with a lot of tight spots then you’ll want to go for something with a smaller cutting width that’ll give you easy access. Of course, the smaller you go, the longer it’ll take to cut the entire lawn which is something to consider if your garden is pretty big.

Cutting Height

This applies to self-propelled and hover mowers. The mower’s height will impact how easy it makes your lawn mow. When you’re mowing on uneven terrain, it can be harder for the blade to make contact with the ground which means you’ll need to set the cutting height lower than normal.

For this reason, I’d suggest choosing a mower that has a versatile range of cutting heights. Most mowers will cut at 25mm but some mowers can cut lower.

Can I level my uneven lawn?

Can I Level Out My Uneven Lawn

A good lawn mower can make it much easier to maintain a lawn that is sloped or uneven. There are people who want to prevent this from happening. If you’re keen to flatten a rugged lawn then it’s probably not as difficult as you imagined.

If there are a series of lumps and bumps that are no higher than 2 centimetres you will probably be able to use top dressing and the job’s a good’un. Anything deeper than this then it’ll be a case of digging it up, filling in any holes and adding new turf on top. This isn’t a difficult job but it can be labour intensive so make sure you’re physically able to do it.

But with all the will in the world, if you don’t look at Why?Uneven lawns will lead to more problems. You might have drainage problems or holes from wildlife. Take a look at what’s causing the problem and deal with that before you do anything else otherwise you’re just sticking a bandaid on it.

How to Mow an Uneven Lawn

If you’re happy to keep your uneven or sloped lawn then that’s fine. However, you must be careful how you mow your lawn if you want to achieve the best results.

Remove all debris

Before you go anywhere near the lawn mower, I’d recommend getting rid of any debris like stones that may be on the ground. This will make mowing much more enjoyable and can improve unevenness. What’s more, with them there, there’s a risk of damage to the mower blade or deck and that’s not what we want after spending a few hundred quid on a new mower.

Take your time

I know that many of you will want to get the lawn mowed and get on with your weekend but I can’t stress enough the importance of taking it slowly if you want a good result.

You may have chosen the best mower for uneven ground and slopes but it’ll still require a bit more work than usual so taking your time will ensure you get every blade of grass. That said, you’ll probably still need to make several passes to get a very even finish so patience is key.

It might be worth making one pass with your mower and another with a trimmer. This is especially helpful if there are tight spots that you can’t get your mower into properly.

Lower the cutting height

Lower The Cutting Height

I mentioned that lawn mowers should have a wider range in cutting heights to ensure that they are in direct contact with the grass. So, when you’re mowing on a bumpy or hilly lawn, it’s important to set that cutting height to a little lower than you would on the flat as you’ll have a much neater and more uniform result.

The Right Direction

I am often asked the first question regarding steep slopes. Which direction should your mower be pointed? The information you will find in your lawnmower manual will help you decide which direction to mow. However, the best rule of thumb is that the slope will determine the mowing direction.

For slopes that are not especially steep, it’s usually best to mow up and down but for anything with more of an incline, it’s often safer to mow laterally.

When mowing up and down, you should move in a slight diagonal. This will prevent the mower slipping.


It’s not very often you’ll find a perfectly flat lawn, at least naturally. Unless you’ve had your lawn landscaped to within an inch of its life, there may be some lumps and bumps. Lawns can also have uneven areas, potholes and steep inclines. This can make it very difficult.

However, by choosing the right lawn mower, you’ll find that the job is far less of a challenge. Self propelled petrol mowers and hover mowers are generally the best option but still keep an eye out for optimum power and other features like large rear wheels that’ll make life safer and easier.
