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. It’s worth pointing out that a zero-turn mower is a slightly different machine in terms of its general handling of terrain than more general lawn tractors and riding mowers. Zero-turn mowers typically have faster ground speeds, smaller wheels, and obviously zero-turn capabilities, usually by way of the steering controls. If you’re not sure what mower is best for you, maybe take a look at Best Riding Lawn Mowers For Hills And Slopes.

Here are some of the most important things to look for if you’re dealing with hilly terrain on a zero-turn mower.

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.

I believe that first impressions matter. The first impression I got when trying the Cub Cadet Ultimate ZT1 was overwhelmingly positive. 

I could tell right away that the manufacturer put a lot of thought into the design and construction of this performing mower. As I learned more about its different features, I found that my first impression was right. The Cub Cadet Ultima ZT1 is a zero-turn mower packed with features that will make your life easier.

Let’s start with the engine. The twin-cylinder 23 hp engine from Kawasaki is an impressive piece of machinery. Its 726cc capacity allows you to operate the mower at a speed of 7.5 mph and 3.5 mph in reverse.

Adjusting the speed is easy thanks to the dual hydrostatic rear-wheel transmission. Equipping this mower with a hydrostatic transmission results in a smooth feeling and reduces the need for maintenance.

The tubular steel frame was another feature I liked right away. The 2” tubes feel sturdy, and there is a special coating that will prevent corrosion. The mower features a comfortable seat with a high back that delivers an ergonomic feeling. I found that the seat and thick rubber mat did an excellent job of absorbing shocks and bumps.

The three blades are also worth mentioning. They are high-quality blades with an anti-corrosion system to protect them. My experience with this Cub Cadet mower is that it produces fine clippings and even results. I liked the high lift deck with its sturdy edges and the convenient pedal and kob control to adjust it from 1 to 4.5.”

Riding this mower around was a pleasure, thanks to the robust rear wheels that provide plenty of traction and stability, even on uneven terrain. The front wheels feature a smooth tread and pivot with ease without digging into the turf.

It’s a mower I can see myself using in the long term. I think the quality motor and hydrostatic transmission will significantly reduce the need for maintenance. Still, the mower has an open frame design that makes its different components easy to access.

I also appreciated the extras and attention to detail. There are many small features that will come in handy, like the LED headlights, the casters that keep the blade in line, the electric start, or the three-way lap bar.

It’s hard to look past the ZT1 as my top recommendation, but the Ariens just takes on feel and control. You can find the latest prices for the Cub Cadet ZT1 here at Home Depot online

But don’t let this detail fool you. This DeWalt mower is ideal for professionals, with its 5.5-gallon fuel tank that enables you to mow up to 10 acres of terrain.

This Cub Cadet mower feels like a smaller version of the other product I tested from this manufacturer. The deck is a little narrower at 48” instead of 50,” but the V-twin motor is similar. The rear-wheel-drive propels the mower forward at up to 7 mph.

The mower also comes with three blades. There is a simple control for adjusting the deck height from 1 to 4,” and it was easy to get a clean and even cut. The wide tires provided the power and stability I needed to mow the lawn with speed and precision.

One of the things I immediately felt made a difference was the armrests. It made the seat feel more supportive and comfortable and made me wish more zero-turn mowers came with this feature.

I liked the deck of this mower because the design allows for excellent airflow. It’s a feature that will prevent clogs and keep you going when you’re mowing tall grass.

The sturdy frame makes this mower an excellent investment. The tubular steel construction made me feel safe. The front casters were a feature that impressed me because they give you excellent control over the orientation of your front wheels, no matter what the terrain throws at you.

The mower features some protective bars behind the operator seat to protect you in case the mower tips backward. However, these bars aren’t as high as other RPOS systems.

The seat feels very comfortable. It’s a durable polymer seat with a built-in suspension. I also liked the controls of the mower because they were very intuitive. All you have to do is push and pull two levers to go or slow down. The main drawback of these controls is that the position of your arms can cause fatigue after a while.

This mower comes with a performing Kohler motor, a smooth hydrostatic transmission, and some 20” rear wheels to give you plenty of traction. The big brother was my top pick, but this 42-inch model is every bit as good…just smaller, meaning mowing takes longer. Check the Cub Cadet 48″ ZT1 price here at Home Depot.

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 the best zero-turn mowers shortlist are recommended for use on hills or slopes by the manufacturer.

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 the mower 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.
