5 Best Zero Turn Mower for Hills and Steep Slopes

Mowing the lawn on hills and steep slopes creates unique challenges. The best zero turn mower for hills should be a product that features a performing motor, a strong transmission, and wheels that deliver plenty of traction.

These features are a few of the things I looked for when testing different zero-turn mowers. I tried several commercial and residential models to determine which ride-on mower is the best buy for those who need to negotiate hilly terrains.

Choosing a Zero Turn Mower for Hilly Terrain

A zero-turn mower is a significant investment, and there are a few features you should consider to pick a product adapted to your needs and budget. Here are some of the most important things to look for if you’re dealing with hilly terrain.

Safety Roll Bar

One of the things you have to worry about when mowing the lawn on an uphill surface is that the steep terrain could cause your mower to roll over.

I recommend choosing a zero-turn mower with a safety roll bar, also known as a rollover protective structure or RPOS, that will prevent the mower from crushing you if it were to tip backward.

Zero Turn Tires for Hills

Zero-turn mowers are different from lawn tractors because they have a cutting deck in front of the operator rather than underneath. This design improves maneuverability and allows you to get into narrow spaces.

The increased maneuverability allows you to cut lawns faster, but you need to make sure the tires will handle slopes and hills.

Zero-turn mowers sometimes have smaller casters to increase speed and maneuverability. However, you’ll get more stability and traction with wider casters. You should also look for larger rear wheels with deep grooves that can propel the mower forward.

Comfort & Controls

It’s important to select a mower that is easy and comfortable to operate, especially if you will operate it for long periods.

Seat & Seat Belt

A high-back seat with plenty of cushioning is a must-have feature. Operating a zero-turn mower can get tiring after a while. An ergonomic seat will reduce fatigue and prevent issues like back pain. 

Reducing fatigue is essential because, as an operator, you need to be alert and aware of your surroundings when operating a mower.

The seat should feature a seat belt or lap bar. This feature ensures that you remain in the seat if the mower were to tip over. Ride-on mowers cause over 36,000 accidents each year, and a seatbelt isn’t a feature you should overlook.

Good Steering Controls

A good zero-turn mower should have precise and responsive steering so you can execute zero turns and get the mower into tight spaces if needed.

Note that operating a zero-turn mower can require some getting used to, but it will be much faster to get used to your new mower if you pick one with controls that feel intuitive.

Hydrostatic Transmission

Belted transmissions eventually fail due to wear-and-tear on the moving parts. If you look at zero-turn mowers in a higher price range, you’ll find that they all use a hydrostatic transmission.

Hydrostatic transmissions use fluids and pumps and provide smooth gear changes. There are fewer moving parts, and the smooth transmission increases comfort. Besides, smooth gear changes translate into an even cut for your lawn.

Engine & Power

You can get an idea of the kind of performance a ride-on mower will deliver by looking at its horsepower rating, engine displacement, and other specs.

The horsepower rating reflects how much power the engine can produce, while the engine displacement rating will tell you how much fuel the motor can potentially burn.

Maximum Speed

You will also have to look at the maximum speed of the mower, both going forward and in reverse. Note that engine horsepower can be high, but a heavy frame can limit the maximum speed of the mower.

Looking at the maximum speed gives you an idea of how powerful the mower is, but keep in mind that you’ll get a more precise cut if you drive slowly.

Fuel Capacity and Run Time

The size of the fuel tank is an important consideration. Is it large enough to allow you to mow an entire yard without having to stop for a refill?

Mowing Slopes with Zero Turn Mowers

There are a few tips to keep in mind when mowing slopes. You should control your speed with the transmission instead of relying on the brakes.

It’s best to go slow, especially if you’re not familiar with the terrain. It’s safer to mow up and down slopes rather than to drive parallel to them. You should also watch out for bumps and holes.

Getting a Clean Cut

A slow speed will help you get a clean and even cut. So will a well-maintained blade. You should inspect the blade after each use and clean any remaining debris caught in it.

You will also need to adjust the deck height to cut the blades of grass to the desired length.

Cutting Deck

The cutting deck is the main body of your mower. It’s where you’ll find the blades. Zero-turn mowers typically use heavy metal decks that lower their center of gravity and provide you with the stability you need to mow slopes.

You should consider the size of the cutting deck, how many blades it houses, and where the discharge is.

Stamped Vs. Fabricated Deck

The fabrication of the cutting deck can differ. Some manufacturers use a single piece of steel and mold it into a stamped deck.

You can also find mowers with a fabricated deck. These decks use several pieces of steel welded together.

While stamped decks tend to be lighter, a fabricated deck can use heavier steel plates suitable for commercial and heavy-duty uses.

Deck Width & Height

A large deck can reduce the maneuverability of your mower. However, it will help you cover a large surface, which means you could finish mowing the lawn faster. It’s about finding the right compromise between coverage and maneuverability.

Zero-turn mowers come with adjustable decks. You’ll have to raise the deck when going uphill and lower it when you go down a slope. Make sure you choose a mower with a deck height setting that is easy to adjust. Having more height settings to choose from will help you get a more precise result.

Driving Zero Turn Mowers on Hills

There are a few safety tips to keep in mind when driving a zero-turn mower on a hill.

Driving Slow

The best zero turn mower for hills should have a transmission that allows you to control your speed with precision.

Maintaining a low speed will help you get an even cut and will give you plenty of time to react if you run into an obstacle and feel the mower becoming unstable. Plus, a slow speed will help the tires grip the terrain to give you the traction you need.

Avoid Wet Grass

Operating a zero-turn mower on wet and hilly terrain isn’t safe. Wait until the grass dries since damp grass won’t give you enough traction.

When Is Steep Too Steep?

Some areas are too steep for you to operate a zero-turn mower safely. You might notice that you don’t have enough control when going downhill or that the front of the mower loses contact with the ground when you go uphill.

Check the documentation for your mower to see if the manufacturer lists any slope inclinations that are unsafe. All items on this best zero turn mowers shortlist are recommended for use on hills or slopes by th emanufacturer.

Do Zero Turn Mowers Work on Uneven Ground?

Yes, you can use a zero-turn mower on uneven ground, slopes and hills. Features like the performing engine, large tires, and heavy deck will give you the stability you need. 

However, it’s essential to watch your speed, avoid obstacles when possible, and always keep your front wheels perpendicular to the slope. Always be sure your mower manufacturer states that th emower is suitable for use on uneven ground and use it as I have described and you will get the best out of your zero turn mower on hilly terrain.
