What is a Zero-turn Lawnmower?

The first commercially available zero-turn mower came onto the market back in 1949.

As the name suggests, they are designed to turn with zero radius, which can save so much time when negotiating obstacles, tackling curved garden designs, or cutting larger lawns.

They work by having a hydraulic system that can independently control each drive wheel, enabling the machine to spin on the spot, and are controlled by two levers as opposed to a traditional steering wheel.

Most zero-turn mowers are gas-powered machines, but rechargeable battery options are becoming more popular and accessible.

When choosing a zero-turn, you need to consider its power capabilities, cutting deck size, safety features, and seating, comfort, and control options.

Are Zero-Turn Lawnmowers Suitable for Hills?

Yes and no. Put it this way – they’re not ideal.

Because… gravity.

It’s easy to lose traction on sloping terrain with any riding lawnmower, and so great care must be taken if you’re attempting to use these machines on such a landscape.

Rolling a riding lawnmower is not unheard of, nor is sliding the vehicle down the hill and into the duck pond.

However, with the right mower, and utilizing a few crucial techniques, you should be able to mow large, hilly areas safely with your zero-turn.

But you can forget it if the gradient is any more than 10-15-degrees. If you have these kinds of slopes, you should check out this review on the best riding mowers for uneven terrain, and you’ll want to look for something with a front-wheel drive.

Watch the video below for some tips and tricks on how to control a zero-turn mower on hills, in order to minimize sliding and prevent rolling.

And read on to discover the best zero turn mower for steep hills – if one exists at all.

How to Choose the Best Zero-turn Lawnmower for Hills

Below, you’ll find a handy, in-depth guide on all the things you should be considering before buying a zero-turn mower.

This is what you need to be looking out for.

Safety First

There are plenty of review websites out there that will tell you that mowing hills with zero-turns is perfectly acceptable and safe – without backing it up with any evidence.

The fact is, zero-turn mowers are not generally designed to tackle hills, with the vast majority aimed at flat or near-flat terrain.

Their big selling point is that they’re the best machines for negotiating obstacles, or mowing unusually-shaped and/or particularly large lawns.

So, when considering safety, it’s important to understand that not every zero-turn mower is capable of handling hills and slopes, and you should only be looking at those that can if this is what will cater to your needs.

As such, I’ve not just included a random selection of “the best zero-turn mowers” in this review – every single one is marketed as being suitable for hills and slopes.

However, some are better than others at handling tricky terrain, so make sure you do your research depending on your own set of circumstances.

It’s not just about how heavy-duty a machine is or if it comes with a roll bar, and I won’t sit here and write that you can use any old mower to tackle any kind of yard.

Deck Size and Height Adjustment

Once you’ve established your zero-turn is capable of handling your yard’s terrain, you should be considering the deck size next.

The larger the deck, the faster you can get the job done.

As a rule of thumb, for anything up to 1/2-acre, a 40-inch deck side should have you covered. You can also check out this article on the best lawnmowers for smaller yards if that’s more suitable for your needs.

For 1/2-acre to two acres, look for models that offer a 40-50-inch cutting deck.

And if you have to maintain anything above two acres, you should pick up a zero-turn lawnmower with a cutting deck over 50-inches.

Take a look at this piece on the best commercial zero-turn lawnmowers if you have an industrial-sized area of land you need to cover.

Don’t forget about the height adjustment, as you’ll want to have the most control over how much you clip your grass – particularly if you’re seriously into lawn care.

You don’t ever want to scalp your turf, as it can cause serious damage to the grass – so make sure your choice of zero-turn mower comes with a good selection of cutting heights.

For more information – including tips on how and when to cut your grass – read this article on how to mow like a pro.

Engine and Power

While it’s commonly more advantageous to look for the fastest zero-turn mower out there, when negotiating hills, speed isn’t always your friend.

But you still want a mower that has enough under the hood to tackle rolling slopes and hilly terrain – if that’s what your backyard calls for.

All the mowers in this review have been chosen because they fit the bill, and come with the power needed to get the job done.

While they vary when it comes to horsepower and speed, for the most part you’re looking at engines anywhere between 22-26 HP – which is more than enough for most yards and gardens.

So, look for machines that are on the higher end of the horsepower scale, with reliable engines that won’t let you down when you most need them.

Transmission

Riding lawnmowers come with three types of transmission – manual, automatic, and hydrostatic.

If you’re shopping for the best zero-turn mower for hills and rough terrain, you’ll want to choose a hydrostatic machine.

They will offer the most control and power, all while ensuring the smoothest ride possible while tackling challenging terrain.

This is an essential requirement – so don’t settle for anything less if you want to safely negotiate anything other than a flat yard.

For more information, check out the video below on how hydrostatic transmission works, and why it’s the best choice for this situation.

Brand

As zero-turn mowers have become more popular for the homeowner market and not just for the school groundskeeper, power-tool brands have been falling over themselves to get on board.

Whereas once there was only one or two, now there are several manufacturers offering this technology to potential buyers.

So, which is the best and who do you go for?

Like all power tool brands, it will probably just come down to personal preference and/or brand loyalty.

You have a reliable Dewalt drill – so it stands to reason they’ll make a reliable zero-turn mower, right?

And while this is true for the most part, don’t overlook brands like Cub Cadet, Ariens, and John Deere – who specialize in outdoor power equipment and vehicles.

I think Cub Cadet in particular seem to be pulling away from the competition when it comes to top-quality (and affordable) zero-turn lawnmowers – their recent award-winning designs and reviews speak for themselves.

To each, their own, but any of the brands featured in this review are more than capable of building a top-quality zero-turn mower that will last you for years to come – with proper use and the right maintenance.

Cost

Zero-turn mowers aren’t cheap, and are notably more expensive than their lawn-tractor counterparts.

And when you start looking at the larger, more powerful machines that are capable of handling hills, then the price tag really shoots up, as they’re designed for more commercial-grade use.

I always recommend suiting the purchase to the job it’s being bought for – that way you’ll have a sound investment that you will last – even if it means spending a little more cash to begin with.

And you can always check out this article on the best budget-friendly zero-turn mowers if you can’t quite stretch to commercially-priced machines.
