Quick verdict
For hilly lawns, the model that stands out is the PowerSmart 21-inch 170cc gas self-propelled mower (our Best Premium). Its rear-wheel drive and 10-inch wheels are specifically built to grip slopes and uneven ground, and the 170cc OHV engine powers through thick grass on inclines where lighter mowers stall.
American Lawn Mower Company 1204
The American Lawn Mower Company reel mower is the lightest option, a 4-blade push reel at just 19 pounds with a 14-inch cutting width. On gentle slopes its low weight makes it easy to control, and its motorless, scissor-like cut is quiet and safe, with no engine to worry about on an incline, though it works best when you mow often before the grass gets tall.

Why you should trust this guide
Mowing hills is as much about traction and control as it is about cutting power, so I focused on how each mower behaves on a slope rather than just its raw specs. I read each product’s published specifications and weighed the drive system, weight, and wheel setup, because those factors decide whether a mower grips an incline or slides and fights you. On a hill, a mower that is heavy but powered can be easier than a light one you have to shove uphill, and I kept that balance in mind throughout.
I have not run these mowers myself, and I want to be clear about that. This comparison is a synthesis of manufacturer data and the trade-offs owners of hillside lawns consistently report, from reel mowers that are safe but strain uphill to self-propelled machines that grip well but weigh more. Where a listing leaned on marketing language, I looked to the concrete specifications instead.
How we evaluated
Traction and drive came first, since a slope is where they matter most. I gave the strongest credit to rear-wheel drive and large wheels that grip inclines, and I weighed weight carefully because it cuts both ways, adding stability but also effort on a manual mower. Wheel size and deck design factored in for how a mower tracks across uneven ground.
Safety and control shaped the rest of the comparison. Motorless reel mowers earned points for having no engine to manage on a slope, while compact cordless mowers earned theirs for being light and maneuverable on smaller hilly patches. I noted where a mower is better on gentle versus steep slopes, and I treated every claim about slope handling as a best case that depends on grass condition and how wet the ground is.
What to look for
- Rear-wheel drive, which grips slopes far better than front-wheel or push designs
- Wheel size, since larger wheels track more securely across uneven ground
- Weight, balancing stability on a slope against the effort of pushing uphill
- Engine or motor power to keep cutting without bogging on inclines
- Maneuverability for tight or terraced hillside sections
- Whether the slope is gentle or steep, which changes the right tool entirely
- Safety features and control, since footing matters most on a hill
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

What to look for
Drive system
Rear-wheel drive gives the best grip on slopes, carrying the mower forward so you steer instead of push uphill.
Wheel size
Larger wheels track more securely across uneven, sloped ground and reduce the chance of slipping.
Weight balance
A heavier powered mower can be more stable on hills, while a light manual one is easier to maneuver but harder to push uphill.
Cutting power
Enough engine or motor power keeps the mower from bogging down when it hits thick grass on an incline.
Slope steepness
Gentle slopes suit light reel and cordless mowers, while steeper hills call for a self-propelled machine.
Our verdict
For hilly lawns, the model that stands out is the PowerSmart 21-inch 170cc gas self-propelled mower (our Best Premium). Its rear-wheel drive and 10-inch wheels are specifically built to grip slopes and uneven ground, and the 170cc OHV engine powers through thick grass on inclines where lighter mowers stall.
FAQs
The PowerSmart 21-inch gas self-propelled is the standout for hills, thanks to rear-wheel drive and large wheels built to grip slopes and uneven ground.
For gentle slopes, yes. Reel mowers like the American and LawnMaster models are light and have no engine to manage, but they strain on steep or overgrown hills.
Rear-wheel drive puts traction where the weight sits when you push uphill, so the mower grips the slope and pulls itself forward instead of slipping.
Light cordless mowers like the KOMASTY 40V are maneuverable on smaller hilly patches, but their shorter runtime and narrow decks make them less ideal for large slopes.
For push mowers, mowing across a slope is generally safer footing. Always follow the mower's own safety guidance, since terrain and traction vary.
