How I Selected the Best Zero-Turn Mower for Hills and Slopes? 

The first thing I considered when selecting the best zero-turn mower for hills was the power of the tools.

Both electric and gasoline-powered zero-turn mowers are much more powerful than push-behind and self-propelled mowers therefore can be used for both residential and commercial purposes. However, if you are a professional and looking for my take on professional-grade machines, check out my best commercial zero turn mower article.

I considered the engine of each mower to determine if they are indeed capable of traveling up slopes and hills up to 20 degrees without any hiccups. Next, I evaluated the cut quality of each zero-turn mower when mowing at full speed and in damp and dry lawn conditions. 

In damp conditions, I also looked at whether the zero-turn mower’s tires accumulated grass as it can affect the traction of the tires. Finally, I tested the maneuverability of each mower to determine how easy they were to steer on flat terrain and slopes and hills. 

Are Zero-Turn Mowers Better than Regular Lawn Mowers for Hills and Slopes? 

The short answer is yes! Zero-turn mowers come with high-performing engines and larger tires, making them a better choice for hills and slopes than regular lawn mowers. 

This range of powerful mowers is also easy to maneuver and allows you to cut grass with little or no effort. These heavy-duty mower models also do a better job at moving around obstacles in your yard than traditional lawn mowers, eliminating the need for trimming. 

Zero-Turn Mowers for Hills and Slopes Buying Guide  

A majority of zero-turn mower models aren’t suitable for slopes and hills, but the 8 models on my list did in fact do an impressive job on this type of terrain. Unlike regular mowers, zero-turn gas mowers and electric zero-turn mowers come at a premium price, so consider the following factors to ease your buying decision. 

Deck Size 

The deck size dictates how much ground a zero-turn mower can cover with a single pass, and can range from 36″ to 52″+. But a larger deck size isn’t a good choice for smaller yards, because these models will be hard to maneuver in small lawns.

Apart from measuring the size of your lawn, it’s a good idea to determine the storage room for the zero-turn mower, as zero-turn mowers with larger decks require more storage space. 

Deck Construction

There are two types of zero-turn mower decks available – fabricated and stamped decks. Fabricated decks are a blend of several pieces of heavy-gauge steel (heavier mowers), whereas stamped mower decks are made from a single piece of steel stamped in a press.

Both types of decks are suitable for residential mowing tasks and offer good performance on hilly terrain. 

Cutting Height 

Different types of grass require different cutting heights, so steer clear from tools with manual height adjustment that requires you to get off and raise the deck by hand. 

Wide Wheels 

Wide wheels provide plenty of traction on flat ground and hilly terrain. A few zero-turn riding lawn mowers come with wide dual tires at the rear and 2 smaller tires at the front, which is ideally great for the ultimate mowing experience. 

Max Speed 

The maximum speed of a zero-turn mower determines how fast you can cut the grass in your yard. If you have a large lawn, slow speed mowers aren’t an ideal choice even though they provide a 0-degree turning radius. 

Comfortable Ride 

Given that you’ll be sitting on a zero-turn lawn mower and using it for heavy-duty work, might as well make the ride comfortable with a plush padded and preferably high-back seat with extra padding similar to riding mowers.

Some zero-turn mowers like the Toro TimeCutter come with a comfortable ride system – the MyRide System, wide cutting deck, excellent engine power, and an adjustable deck, so consider this zero-turn riding mower for larger lawns with steep hills, rough terrain, and uneven ground.

Final Thoughts

Mowing hills and slopes requires extra effort with a traditional lawn mower but zero-turn lawn mowers make this task fairly easy, thanks to their powerful efficient engines, adjustable deck lifting, and some models with a roll over protection system.

Even though all 8 mower models on this list perform well, the Cub Cadet mower is my personal top choice and is rated as the best zero-turn mower for hills.
