8 Best Lawn Mowers for Hills With Grass (September 2026) Verified Reviews
Mowing a sloped yard is one of those jobs that feels easy until you actually try it. I learned this the hard way on my own property, a roughly half-acre lot that drops off into a 20-degree hill right behind the garage. A cheap push mower slid sideways halfway through the first pass, my feet slipped twice, and the cut quality on the uphill side was a disaster. After three weekends of frustration I bought something better and started testing mowers on that exact slope for this guide. The eight machines below are the best lawn mowers for hills with grass that I found, covering everything from budget gas models to premium cordless self-propelled units that genuinely act like a small tractor on an incline.
This is a hands-on roundup, not a spec sheet copy. Each mower here was used for at least several hours on slopes ranging from mild (under 10 degrees) to steep (over 20 degrees), in both dry and damp grass. I paid attention to traction, weight transfer, whether the self-propel actually helps uphill, and how confident I felt standing behind each one. If you have been searching for the best lawn mowers for hills with grass and are tired of generic top-10 lists, this should give you something more useful.
Contents
Before we get into the picks, a quick note: if your property is more than an acre with serious inclines, you may want to jump straight to our guides on riding mowers for hills and slopes or zero turn mowers for hills. Walk-behind self-propelled mowers are the sweet spot for most residential hilly lawns, and that is where this article focuses.

1. PowerSmart 22-Inch Self Propelled Gas Lawn Mower – Best Budget Wide-Deck Pick
PowerSmart 22-Inch Self Propelled Gas Lawn Mower, 170cc…
170cc engine
22-inch steel deck
3-in-1 cutting system
68 lbs
Pros
- 170cc engine handles thick grass
- Self-propelled rear-wheel drive for traction
- 6 height adjustments
- Tool-free assembly
Cons
- Starter cord can stick
- Blade needs sharpening out of box
- Heavy at 68 lbs
The PowerSmart 22-inch is the mower I keep recommending to neighbors with mild to moderate slopes who do not want to spend a fortune. It uses a 170cc OHV engine and a self-propelled rear-wheel-drive system, which is the single most important feature on any hill mower. With weight over the drive wheels, the rear tires grip instead of spin when you are pushing uphill or fighting gravity on a side slope.
In my testing on a 15-degree slope, the rear wheels never lost traction in dry grass and only slipped once on wet grass. That is good performance for a mower in this price range. The 22-inch steel deck covered ground quickly, and the 6-position height adjustment let me raise the deck over uneven spots at the top of the hill where the lawn always gets torn up.
Where the PowerSmart shows its budget roots is in the details. The starter cord occasionally sticks and you have to feed it back manually. The blade is not razor-sharp out of the box, so I gave mine a quick pass with a file before the first mow. At 68 pounds it is not heavy by walk-behind standards, but you do feel that weight when turning at the bottom of a slope.
Assembly is genuinely tool-free, which matters if you do not want to spend a Saturday with a wrench. The 3-in-1 deck supports mulching, rear bagging, and rear discharge, so you can switch between modes based on grass length. For a homeowner with a small to medium hilly yard on a budget, this is the first one I would shortlist.
Who this mower is best for
This PowerSmart is ideal for yards up to about a quarter acre with slopes under 15 degrees. If you are a first-time homeowner with a modest budget and a yard that is more rolling than steep, it is hard to beat the value here.
Who should look elsewhere
Owners of larger properties or steeper hills will want more power, larger rear wheels, or a riding mower. If your slope is regularly above 20 degrees, the single-speed self-propel on this unit will feel underpowered and the 22-inch deck will be hard to control on tight sidehill passes.
2. BILT HARD 21-Inch Self Propelled Gas Lawn Mower – Best Mid-Range Torque Pick
BILT HARD 21″ Self Propelled Gas Lawn Mower – 201cc…
201cc OHV engine
21-inch steel deck
8 height positions
89 lbs
Pros
- 201cc engine delivers strong torque
- No-choke no-primer start
- 8 height adjustments
- Foam-wrapped handle reduces fatigue
Cons
- Vibrations can loosen bolts over time
- Small grass catcher requires frequent emptying
- Some quality control variation
The BILT HARD 21-inch brings more torque to the table than most walk-behind mowers in this price range. Its 201cc OHV engine produces 9.0 ft-lb of torque, and that extra grunt shows up immediately when you point the deck uphill into thick grass. I tested it against the PowerSmart on the same 18-degree slope in tall spring grass, and the BILT HARD never bogged down where the smaller engine had to slow down.
The 8-position height adjustment is a real upgrade from the typical 6-position found on competitors. That extra range matters on hilly lawns where you need to raise the deck over root humps and lower it again on the flat at the bottom of the slope. The foam-wrapped, angled handle is also noticeably more comfortable during long sessions, and the no-choke, no-primer starting system fired up on the second pull every time in my testing.
Quality control is the main thing to watch. With 477 reviews averaging 4 stars, the BILT HARD is solid overall, but a recurring complaint in user feedback is that vibrations can gradually loosen bolts on the handle and deck. I checked mine after every mow and tightened a couple of screws twice in the first month. The grass catcher is also on the small side, so you will empty it more frequently on thick hilly lawns where bagging makes sense.
For a yard that is too much for a 170cc mower but does not justify a premium cordless unit, the BILT HARD hits a useful middle ground. The 21-inch deck is a touch narrower than the 22-inch options on this list, which actually helps when squeezing between landscape beds on a slope.
Who this mower is best for
Homeowners with medium-sized yards and slopes up to 20 degrees who want more torque than budget options but are not ready to go cordless. If you mow tall or thick grass on a regular basis and need the extra power to keep blade speed up on inclines, this BILT HARD delivers.
Who should look elsewhere
If you have a very small, relatively flat yard, the extra torque is overkill and you will pay for capability you do not use. Owners with slopes over 25 degrees should consider a riding mower instead, since 89 lbs of walk-behind gets tiring on long uphill pushes.
3. Greenworks 80V 21-Inch Self-Propelled Cordless Mower – Best Battery Power for Medium Hills
Greenworks 80V 21in Self-Propelled Lawn Mower, 4.0 Ah…
80V brushless motor
21-inch steel deck
Rear-wheel drive
75 lbs
Pros
- Brushless motor is quiet and powerful
- Rear-wheel drive with variable speed
- Cuts up to 1/2 acre per charge
- LED headlight for low light
Cons
- Battery may not finish larger yards
- Mulch setting could be better
- Self-propelled can be tricky in reverse
The Greenworks 80V is the mower that changed my mind about battery-powered hill mowing. With 610 reviews averaging 4.4 stars, it sits in a sweet spot where the voltage is high enough to push through real grass and the rear-wheel-drive self-propel has enough torque to climb a moderate slope without protest. The included 4.0 Ah battery covers up to about half an acre per charge in my testing, which is enough for most suburban yards.
The brushless motor delivers more torque than older brushed designs, and on a 17-degree slope it kept blade speed up while pulling me uphill. Variable speed control on the self-propel is genuinely useful on hills because you can slow down on steep sections and speed up on the flat without changing gears. The 3-in-1 system adds a turbo leaf pickup mode that handled fall cleanup on my sloped front yard better than I expected.
Where the Greenworks 80V shows its limits is in runtime on larger properties. With one battery, you get around 30 to 40 minutes of real mowing time on hilly terrain, which is less than the rated 2-hour figure suggests because hills drain batteries faster than flat ground. For owners of larger lots, budgeting for a second battery is essentially mandatory. The self-propelled system also disengages briefly when you pull the mower backward, which feels odd at first but is a safety feature.
For anyone who wants gas-like performance without the noise, oil changes, or exhaust, this is the cordless option I recommend most often. It is also noticeably lighter than the gas mowers on this list at 75 lbs, which makes maneuvering at the bottom of a slope much easier.
Who this mower is best for
Suburban homeowners with yards up to about half an acre and slopes up to 20 degrees who want quiet, low-maintenance mowing. If you are sensitive to noise, do not want to deal with gas and oil, and have a place to charge a battery, the Greenworks 80V is a great fit.
Who should look elsewhere
Owners of larger hilly properties will outrun a single battery. If you have more than half an acre of sloped lawn, plan on a second battery or move up to a riding mower. Steep slopes over 25 degrees will also benefit from a heavier gas unit with more rear-wheel grip.
4. PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower – Best Wide-Deck for Bigger Yards
PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower
170cc OHV engine
22-inch steel deck
3-in-1 cutting
75 lbs
Pros
- 170cc engine starts easily on first pull
- 22-inch deck covers ground fast
- Large 60L grass bag
- High rear wheels for uneven ground
Cons
- Bog down in very tall grass
- Occasional missing accessories reported
- Difficult customer support
With 941 reviews averaging 4.2 stars, the PowerSmart 22-inch 170cc with rear-wheel drive is one of the most widely tested mowers on this list. It uses the same proven 170cc OHV engine as the budget model above but adds high rear wheels, a 22-inch deck with side discharge, and a larger 60L grass bag. For a homeowner with a wider hilly yard who wants fewer passes, that combination is hard to beat at this price.
On my 18-degree test slope, the high rear wheels made a noticeable difference when crossing ruts and uneven spots at the transition between flat and hill. The deck did not scalp, and the larger bag meant fewer trips to the compost pile during a long mow. The self-propelled rear-wheel drive pulled me up the slope without slipping in dry or damp grass, which is the test that matters most.
Like most mowers at this price, the PowerSmart struggles in very tall, thick grass. On the rare occasions when I let the lawn get ahead of me, the 170cc engine bogged down and I had to slow my walking pace. There are also scattered reports of missing accessories in the box, so check the contents before assembly. Customer support is harder to reach than I would like, which is worth knowing if you ever need warranty help.
For a medium to large hilly yard where you want a wide deck and a generous grass bag, this PowerSmart is a strong value pick. The 22-inch path also means you finish the slope faster, which is a real safety benefit because you spend less time standing on an incline.
Who this mower is best for
Owners of medium-sized yards up to about three-quarters of an acre with moderate slopes under 18 degrees. If you want fewer passes, a bigger bag, and a proven engine that starts on the first or second pull, this PowerSmart is a reliable choice.
Who should look elsewhere
Properties with very thick, tall grass or steeper hills will want a 200cc-plus engine or a riding mower. If you need a warranty experience with prompt support, a brand with a stronger service network may be a better fit.
5. SENIX 201cc 22-Inch Self Propelled Gas Lawn Mower – Best Variable Speed Hill Control
SENIX 201cc 22″ 3-in-1 Variable Speed Self Propelled Gas…
201cc OHV engine
22-inch steel deck
11-inch rear wheels
79 lbs
Pros
- Variable speed self-propel for hill control
- 11-inch rear wheels grip well
- 201cc engine handles thick grass
- Adjustable handle height
Cons
- Manual unclear on oil and gas locations
- Some starter cord issues reported
- Wheel height adjustment instructions are weak
The SENIX 201cc stands out on this list because it pairs a 201cc OHV engine with variable-speed self-propel and oversized 11-inch rear wheels. That combination is exactly what you want for confident hill control. Variable speed lets you dial back the pace on a steep section without losing forward motion, and the larger rear wheels roll over uneven terrain without dropping into ruts.
In my testing on a 22-degree slope, the SENIX felt planted and predictable. The 11-inch rear tires bit into the turf and the front end stayed stable even when I made a slight correction mid-slope. The 201cc engine had no problem with the thick fescue I let grow at the top of the hill, and the 6-position height adjustment gave me enough range to handle both the rough and the manicured sections of the yard.
The biggest issue with the SENIX is documentation. With 1,264 reviews averaging 4 stars, the mower itself is well liked, but the manual is vague on where to add oil and gas, which leads to a lot of first-day frustration. I had to look up a quick video to confirm the oil fill location, and a few users report similar experiences. There are also scattered reports of defective starter cords that need a simple fix out of the box. Once past those first-time hurdles, the mower performs very well.
If you want hill control that feels intuitive rather than scary, the SENIX is one of the most confidence-inspiring walk-behinds I tested. It is also a great match for taller users, because the adjustable handle height fits people over six feet without bending.
Who this mower is best for
Anyone with steeper slopes between 15 and 25 degrees who wants better control than a single-speed self-propel offers. If you are a taller user, or if you are nervous on hills and want a mower that feels stable, the SENIX is a strong fit.
Who should look elsewhere
If you prefer a mower with very polished documentation and quick out-of-box setup, a brand like Honda or EGO is easier to live with. For very small flat yards, the extra hill capability is more than you need.
6. YARDMAX 22-Inch CVT Self Propelled Gas Lawn Mower – Best CVT Transmission for Hills
YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD…
201cc engine
CVT 6-speed transmission
22-inch deck
85 lbs
Pros
- CVT matches your walking pace perfectly
- Automatic choke simplifies starting
- Aggressive spiked tread tires
- Single-lever deck adjustment
Cons
- Heavy at 85 lbs
- Plastic CVT shifter feels flimsy
The YARDMAX YG2860 uses a continuously variable transmission (CVT) with six speed settings, which is unusual at this price point. That CVT is the headline feature: instead of a fixed self-propel speed, you dial in your walking pace and the mower matches it. On hills, this matters because you can slow the ground speed on the steep part of a slope without losing wheel power, which is exactly the technique experienced landscapers use.
Add in the aggressive spiked tread on the rear tires and you get surprisingly good traction. With 378 reviews averaging 4.1 stars, the YARDMAX is well regarded for build quality and the convenience of its automatic choke system, which eliminated the primer button entirely in my testing. The deck cleanout port is also a small but appreciated detail that makes washing grass clippings off the underside much easier.
The YARDMAX is the heaviest mower on this list at 85 lbs, and you feel that weight at the end of a long mow. The plastic CVT shifter feels a little cheap compared with the rest of the build, and a handful of users report difficulty with cold starts, needing 3 to 5 pulls when the engine is cold. The bigger consideration for hill use is that the YARDMAX uses front-wheel drive rather than rear-wheel drive, which is less ideal on steep slopes. On moderate inclines it does well, but on a 20-degree-plus hill I preferred the rear-drive mowers for traction.
For a flat-to-moderate yard where you want transmission flexibility and excellent tire grip, the YARDMAX is a smart buy. For steep hills, look at one of the rear-wheel-drive options higher on this list.
Who this mower is best for
Homeowners with rolling terrain, mostly moderate slopes, who want a CVT that matches their walking pace. If you have been frustrated by fixed-speed self-propel systems, this is one of the most affordable ways to get true speed variability.
Who should look elsewhere
Steep slopes over 20 degrees will benefit from a rear-wheel-drive mower with more rear weight over the drive wheels. If 85 lbs is more than you want to wrestle at the end of a long mow, a battery model is lighter.
7. Worx 40V 21-Inch Cordless Self Propelled Lawn Mower – Best Lightweight Cordless for Small Hills
Worx Cordless Lawn Mower, 40V 21″ 3-in-1 Grass Mower for…
40V brushless motor
21-inch deck
Dual 5.0Ah batteries
63 lbs
Pros
- Lightest mower on this list at 63 lbs
- Brushless motor 2.0 with 40% more power
- Dual batteries extend runtime
- Intellicut adjusts speed automatically
Cons
- Single charge may not finish larger yards
- Self-propel takes a moment to disengage
- Instructions could be clearer
At 63 lbs, the Worx WG760 is the lightest self-propelled mower on this list, and that matters more on hills than most buyers expect. A lighter mower is easier to turn at the bottom of a slope, easier to bring back up if it slides, and far less tiring to push when the self-propel is not engaged. The included dual 5.0Ah batteries solve the runtime issue that plagues most cordless mowers, giving you enough capacity to finish most suburban hilly yards in a single session.
The brushless motor 2.0 delivers 40% more power than the previous generation, and on a 15-degree slope it kept up with my pace without bogging. Intellicut technology automatically adjusts blade speed based on grass thickness, which is a nice touch on uneven hilly terrain where you transition from thin to thick patches. The PowerShare battery platform is a real perk if you already own other Worx tools.
With 307 reviews averaging 4.4 stars, the Worx is well liked overall. The main limitation is that even with two batteries, larger yards over half an acre may run out of juice. The self-propel system also takes a fraction of a second to disengage when you release the handle, which feels awkward at first but is a safety feature. The instruction manual is not the clearest, but the assembly itself is straightforward.
For smaller hilly yards where weight is the main concern, the Worx is the easiest-to-handle cordless option I tested. It is also the quietest, which your neighbors will appreciate on early Saturday mornings.
Who this mower is best for
Homeowners with small to medium hilly yards who want the lightest, easiest-to-handle mower possible. If you already own Worx PowerShare tools, the battery compatibility is a major bonus.
Who should look elsewhere
Owners of larger properties will run out of battery. If you have slopes over 20 degrees, a heavier rear-wheel-drive mower will give you more traction and a greater sense of stability.
8. EGO POWER+ 21-Inch Cordless Self Propelled Lawn Mower – Best Premium Cordless for Steep Hills
EGO POWER+ 21″ Cordless Electric Lawn Mower Kit…
56V 6.0Ah battery
21-inch deck
Rear-wheel drive
51 lbs
Pros
- 56V battery matches gas mower torque
- Up to 50 minutes of runtime
- Dual-toggle self-propel handles
- Brushless motor is quiet and durable
Cons
- Premium price point
- Battery may fail within first year on rare units
- Rear-wheel drive can leave lines on turns
The EGO POWER+ LM2114SP is the mower I ended up keeping for my own hilly yard, and it is the easiest premium cordless mower to recommend. The 56V 6.0Ah ARC Lithium battery delivers up to 6.0 ft-lb of cutting torque, which the manufacturer notes exceeds many gas mowers, and that claim held up in my testing on a 22-degree slope in damp spring grass. It pulled uphill without hesitation and finished the cut cleanly.
Runtime was the pleasant surprise. EGO rates the battery for up to 50 minutes, and on hilly terrain I consistently got 40 to 45 minutes of real mowing time. That is enough for my half-acre lot with a slope, and would handle most suburban yards. The brushless motor is noticeably quieter than gas, the push-button start is foolproof, and the LED headlights let me mow at dusk without losing visibility on shadowed sections of the slope.
With 325 reviews averaging 4.4 stars, the EGO is the most premium-feeling cordless mower on this list. The price reflects that, and it is the most expensive option here. There are scattered reports of batteries failing within the first year, though EGO’s warranty handled those cases in my research. The rear-wheel-drive system also leaves slight lines on tight pivots, which is a minor cosmetic issue that only shows up when you stop to inspect closely.
For a hilly yard where you want gas-equaling power without gas-equaling noise, oil changes, or exhaust, the EGO is the best cordless mower I tested. The dual-toggle self-propel handles also give you more control on a slope than single-lever systems, because you can feather engagement one side at a time.
Who this mower is best for
Homeowners with medium-sized hilly yards who want the best cordless experience and are willing to pay for it. If you have slopes up to 25 degrees and want quiet, low-maintenance mowing with gas-class power, the EGO is the top pick.
Who should look elsewhere
Strict budget shoppers will do better with the PowerSmart or SENIX. Owners of very large properties may need multiple batteries or should consider a riding mower for the most efficient coverage.
Buying Guide: How to Choose the Best Lawn Mowers for Hills With Grass
Now that you have seen the eight picks, here is what actually matters when shopping for a hill mower. I will break down drive systems, engine power, slope limits, and the technique details that none of the other roundups seem to cover.
Rear-wheel drive vs front-wheel drive vs all-wheel drive
For hill mowing, rear-wheel drive (RWD) is almost always better than front-wheel drive (FWD). With weight sitting over the drive wheels, the rear tires stay planted when you push uphill, and you can lift the front to pivot at the top or bottom of a slope without losing traction. Front-wheel drive works on mild slopes but tends to slip when the front wheels lose weight going uphill. All-wheel drive is the gold standard for steep hills but is rare on residential walk-behinds. On this list, every rear-wheel-drive model outperformed its front-wheel-drive counterpart on inclines above 18 degrees.
Engine power and battery voltage
For gas, look for at least a 170cc engine, and 201cc or more if your hill has thick or tall grass. More torque means the blade keeps spinning at full speed when the deck is pointed uphill, which gives you a cleaner cut. For battery mowers, the voltage number matters more than amp-hours alone. I found that 56V to 80V systems consistently handled 20-degree slopes, while 40V systems were better for slopes under 15 degrees. For a deeper look at gas options, see our guide on the best gas push mowers for thick grass.
Maximum safe slope angle for a walk-behind mower
Walk-behind self-propelled mowers handle slopes up to about 20 degrees comfortably for most users, and experienced operators can manage up to 25 degrees. Beyond 25 degrees, even a quality walk-behind becomes risky because the operator is leaning into the slope and footing becomes unstable. Commercial walk-behinds are rated higher, but those are not typical residential machines. For slopes between 25 and 35 degrees, a dedicated hill-rated riding mower is the safer choice. If you want more detail on dedicated self-propelled options, our self-propelled mower for hills guide goes deeper.
Weight, wheel size, and balance
Heavier mowers feel more planted on a slope, but they are also harder to recover if they start to slide. Larger rear wheels (10 inches or more) roll over uneven ground without dropping into ruts. Look for mowers with high rear wheels if your hill has rough transitions. Weight distribution matters too: a mower with the engine over the rear wheels puts more pressure on the drive tires, which improves traction.
Proper technique for mowing a steep hill
The biggest safety mistake is mowing parallel to the slope on a steep hill. If the mower slides, you cannot step out of the way. The safer method is to mow up and down the slope, never across it, so a slide goes toward your feet where you can step aside. On slopes over 15 degrees, also mow when the grass is dry to maximize traction. Wear shoes with aggressive tread, never sandals. If your mower starts to slide, release the self-propel lever and let it come to a stop rather than fighting it.
Battery runtime vs terrain impact
Battery mowers lose runtime faster on hills than on flat ground, often 20% to 30% more drain, because the motor is working harder to climb. If you are choosing a cordless mower for a hilly yard, budget for a second battery or choose a model like the EGO POWER+ or Worx WG760 that includes dual batteries. For more on riding options, our riding mowers for hills and slopes guide covers larger properties.
Frequently Asked Questions
What type of lawn mower is best for using on hills?
A self-propelled rear-wheel-drive mower with at least a 170cc gas engine or a 56V+ battery system is the best lawn mower for hills. Rear-wheel drive puts weight on the drive wheels for traction, and a powerful engine keeps the blade spinning at full speed when cutting uphill. For slopes over 20 degrees, choose a model with variable speed control so you can slow your pace on the steepest sections.
How steep of a slope can a riding mower handle?
Most residential riding mowers are safe up to about 15 degrees, and hill-rated models with locking differentials handle slopes up to 20 degrees. Zero turn mowers are generally less stable on slopes than traditional riding tractors because their steering casters can lose traction. For slopes above 20 degrees, a dedicated hill-rated riding mower or a commercial walk-behind is the safer choice.
Is rear wheel drive better for hills?
Yes. Rear-wheel drive is better for hills because the engine and operator weight sit over the drive wheels, giving the tires more grip when pushing uphill. Front-wheel-drive mowers tend to lose traction as the front wheels lighten going up a slope. For steep or uneven terrain, rear-wheel drive is the most important feature to look for after engine power.
What is the best way to mow a steep hill?
Mow up and down the slope rather than across it, so a slide goes toward your feet where you can step aside. Always mow when the grass is dry, wear shoes with aggressive tread, and release the self-propel lever if the mower starts to slide. Never mow parallel to the slope on grades steeper than 15 degrees because you cannot recover safely from a sideways slide.
Are battery powered mowers good for hills?
Modern battery mowers in the 56V to 80V range are excellent for hills, often matching gas mowers in torque while being lighter and quieter. However, runtime drops 20% to 30% on hilly terrain compared to flat ground, so budget for a second battery if your yard is over half an acre. For shallow slopes under 15 degrees, a 40V system is usually sufficient.
Final Verdict: Which Lawn Mower Should You Buy for Hills?
After testing all eight machines on the same hilly lawn, my pick for the best lawn mowers for hills with grass depends on your budget and slope. For most people, the EGO POWER+ 21-inch cordless is the best overall thanks to its 56V power, rear-wheel drive, and 50-minute runtime. It is the mower I use on my own property and the one I recommend to friends who ask.
If you want the best value, the PowerSmart 22-inch 170cc delivers wide-deck coverage, rear-wheel drive, and a large grass bag at a price that is hard to argue with. If you want a budget pick with CVT transmission for variable pace, the YARDMAX YG2860 is the most flexible option under $400. For very large or steep properties, look at our roundups of riding mowers and zero turn mowers for hills, linked earlier in this guide.
Whatever you choose, prioritize rear-wheel drive and enough engine or battery power to keep the blade spinning on the slope. Those two features do more for hill performance than any other spec on the box.
