A strong walk-behind mower for hills needs dependable traction and a drive system that helps you control its pace; the right choice depends on whether your slope has grass, rough brush, or both. Among these ten options, the MechMaxx SFM27W stands out for slopes because its rubber tracks are specified for traction and stability on slopes and rough terrain. For maintained lawns, the Greenworks 60V 21in Self-Propelled Lawn Mower adds rear-wheel drive and on-the-go pace adjustment, while the YARDMAX 22 in.
Select PACE pairs self-propulsion with aggressive-tread tires. These are not interchangeable jobs: string and rough-cut mowers handle vegetation that ordinary lawn mowers are not designed around.
Compare traction, cutting width, power source, and the kind of grass or brush you need to clear before choosing.
The MechMaxx 27-inch Flail Mower is the strongest listed choice for challenging hills because its rubber tracks are described as providing traction and stability on slopes and rough terrain. Its self-propelled drive, 3-forward/1-reverse transmission, and 27-inch flail deck also suit rougher vegetation than a typical lawn mower. For maintained grass rather than rough terrain, consider the Greenworks 60V 21-inch Self-Propelled Mower, which specifies rear-wheel drive for slopes and adjustable pace.

Detailed Reviews: Best Walk Behind Mower For Hills

#1 · Best Overall
1. MechMaxx 27-inch Flail Mower
- Dimensions: 72.2"D x 32.9"W x 42"H
- Weight: 374 lb
- Material: Alloy Steel
Best for: Rough Terrain and Slope Traction.
Why it ranks #1: Rubber tracks are specified for slope and rough-terrain traction and stability; self-propulsion and reverse help manage its 27-inch flail deck.
Rubber tracks provide the MechMaxx flail mower with traction and stability on slopes and rough terrain, a defining feature for challenging mowing conditions. Its 27-inch cutting width, self-propelled drive, and three-forward, one-reverse transmission support covering demanding ground while retaining options for maneuvering.
A 10 HP, 302cc gasoline engine with electric start powers the flail mower, while the side-mounted lever sets cutting height from 0.8 to 3.2 inches for uneven or rough terrain. The transmission’s three forward speeds and reverse give you control over movement, and the tracks are specified to improve grip and stability. At 374 pounds, its listed weight is also a practical factor for transport and storage.
- Rubber tracks for slope and rough-terrain traction
- 27-inch cutting width
- Electric-start 10 HP, 302cc engine
- Side-lever height adjustment from 0.8 to 3.2 inches
- Its 374-pound listed weight makes transport and storage challenging.
Skip it if you need a lightweight mower for routine lawn care; the Greenworks 40V 16-inch push mower weighs 37.5 pounds.
Choose the MechMaxx for rough terrain and slopes where tracked traction, flail mowing, and a wide cut suit the job. Its 374-pound weight makes site access and storage essential fit considerations.

#2 · Best Lawn Mower
2. Greenworks 60V 21-inch Mower
- Dimensions: 68.89"D x 25.63"W x 42.12"H
- Weight: 65 lb
- Material: Plastic
Best for: Battery Mower for Sloped Yards.
Why it ranks #2: Rear-wheel drive is specified for tackling slopes, with adjustable pace, a 21-inch deck, and two 4.0Ah batteries included.
Rear-wheel-drive traction and on-the-go pace adjustment give the Greenworks 60V mower controls suited to slopes and thick grass. Its self-propelled operation helps move the 21-inch mower forward, while the two included 4.0Ah batteries are specified to cover up to three-quarters of an acre per charge, depending on terrain and technique.
A brushless 60V motor supplies the mower’s power, and the paired batteries support the stated coverage for larger yards. The 21-inch deck offers a wider pass than a compact mower, while seven-position height adjustment lets you change cutting height for differing lawn conditions. Greenworks also lists operation at three times quieter than gas mowers, plus instant starts and zero emissions, which shape the operating experience.
- Rear-wheel-drive self-propelled traction
- Adjustable pace while mowing
- Two 4.0Ah batteries included
- Seven-position cutting-height adjustment
- Stated coverage is up to three-quarters of an acre per charge, varying with terrain and technique.
Skip it if you want a walk-behind string mower for brush rather than a blade deck; the Earthquake 60V model cuts a 22-inch swath.
This Greenworks fits owners seeking a self-propelled battery mower for sloped or thick-grass lawns, with two batteries and adjustable pace. Keep its terrain-dependent coverage limit in mind when matching it to a large property.

#3 · Best Tire Traction
3. YARDMAX 22-inch Select PACE
- Weight: 95.7 lb
- Material: Plastic, Stamped Steel
Best for: Pace-Controlled Self-Propelled Mowing.
Why it ranks #3: Self-propelled front-wheel drive, aggressive spiked tire tread, and six selectable CVT speeds support traction and pace adjustment on maintained lawns.
YARDMAX’s six-speed CVT lets you adjust mower pace to your walking speed, helping maintain control as your pace changes across the yard. Aggressive spiked-tread rubber tires add traction and maneuverability, while the front-wheel-drive self-propelled format supports forward movement during routine mowing.
The 22-inch deck pairs with a 201cc engine and a three-in-one cutting system, giving you a wide swath and multiple ways to manage clippings. Its automatic choke removes the need to prime or choke before starting, simplifying startup. The CVT’s six-speed shift lever makes pace selection direct, while the high-wheel design and treaded tires are intended to improve maneuverability and grip over varied ground.
- Six-speed CVT adjusts pace to walking speed
- Aggressive spiked-tread rubber tires
- 22-inch, three-in-one mower
- Automatic choke requires no priming or choking
- Front-wheel drive may be less suited to buyers prioritizing rear-wheel-drive slope traction.
Skip it if you want a cordless mower with stated slope-focused rear-wheel drive; the Greenworks MO60L424 offers that configuration.
Pick the YARDMAX for lawn mowing where self-propelled pace control, a 22-inch deck, and multiple clipping modes fit your routine. Its listed front-wheel drive is an important consideration if rear-wheel-drive traction is your priority on slopes.

#4 · Best Rough Cut
4. Swisher Predator Rough Cut
- Dimensions: 87"D x 27"W x 42"H
- Weight: 252 lb
- Material: Alloy Steel
Best for: Dense Underbrush and Saplings.
Why it ranks #4: Its self-propelled 24-inch rough-cut deck clears saplings up to 1.5 inches and uses large pneumatic chevron tires for uneven terrain.
The Swisher’s 24-inch self-propelled rough-cut deck clears saplings up to 1.5 inches thick, making it a specialized option for dense growth rather than routine lawn finishing. Large pneumatic chevron tires support traction on uneven ground, and a four-speed transmission with reverse aids maneuvering in tight areas.
An 11.5 HP, 344cc Briggs & Stratton recoil engine powers the mower, while the self-propelled drive reduces the need to push its 252-pound listed weight. The four forward speeds and reverse give you choices when negotiating rough or confined areas. A 3-to-4.75-inch cutting-height range accommodates varied terrain, and the adjustable-height handlebar lets the operator tailor hand position and control.
- Clears saplings up to 1.5 inches thick
- 24-inch self-propelled rough-cut deck
- Four-speed transmission with reverse
- Pneumatic chevron tires for uneven ground
- Its 252-pound listed weight makes transport and storage more demanding.
Skip it if you need a lightweight mower for ordinary lawn turf; the Greenworks 40V 16-inch push mower weighs 37.5 pounds.
The Swisher suits property owners clearing thick undergrowth and saplings where its rough-cut deck and traction features match the terrain. Its 252-pound weight and substantial dimensions make access, transport, and storage important considerations.

#5 · Best Brush Clearing
5. Earthquake 60V String Mower
- Dimensions: 50.37"D x 40.06"W x 17.44"H
- Weight: 40 lb
- Material: Alloy Steel, Plastic
Best for: Cordless Brush and Rough Growth.
Why it ranks #5: Fourteen-inch airless wheels and a string cutting head suit brush and trimming tasks; two 4Ah batteries are listed for up to 90 minutes.
Two included 4Ah batteries provide up to 90 minutes of stated runtime for the Earthquake 60V walk-behind string mower, giving you more time between charging stops. Its 22-inch cutting diameter and variable cutting-speed dial help tailor brush-clearing pace to the task.
The direct-drive brushless motor is specified to extend battery life and reduce maintenance, while the cutting head reduces weed wrap. A tool-less cutting-height adjustment spans 1.5 to 4 inches, allowing height changes without tools. The 14-inch airless wheels avoid flat tires, and simple line replacement supports ongoing use; the included starter pack has both 0.095-inch and 0.155-inch line for different growth.
- Two 4Ah batteries included
- Up to 90 minutes of stated runtime
- Tool-less 1.5-to-4-inch height adjustment
- 14-inch airless wheels
- Maximum stated runtime is 90 minutes across the two included batteries.
Skip it if you need a blade mower for a maintained lawn; the Greenworks MO60L424 is a 21-inch self-propelled lawn mower.
Choose this Earthquake for cordless trimming and brush work when long stated runtime, adjustable cutting height, and airless wheels suit the property. Its string-mower cutting head is the key fit consideration for buyers expecting a conventional lawn finish.

6. Earthquake Walk-Behind String Mower
- Dimensions: 53.2"D x 23.39"W x 40.6"H
- Material: Steel, Rubber, Plastic
Best for: Rough Edges and Brush Clearing.
Why it ranks #6: Its all-terrain description, extra-wide airless wheels, and 22-inch string cutting diameter fit trimming and brush clearing better than lawn finishing.
The Earthquake’s 22-inch Hurricane cutting head has no spots for weeds to grab, helping reduce weed wrap as you clear rough growth. Its walk-behind format lets you tackle brush and trimming without carrying a handheld trimmer, while extra-wide airless wheels support movement across varied terrain.
A 160cc four-cycle Viper engine powers the string mower, while the adjustable cutting head accepts 0.095-inch line for lighter growth or 0.155-inch line for tougher weeds. That choice lets you match the cutting line to the task, and tool-less adjustment makes changing it more straightforward. The 2.5-by-14.5-inch airless wheels avoid flat-tire concerns, and the adjustable handlebar offers another way to tailor operation to the user.
- 22-inch cutting diameter
- Hurricane head avoids weed-grabbing spots
- Accepts 0.095- or 0.155-inch cutting line
- Extra-wide airless wheels
- String line requires replacement as it wears or breaks.
Skip it if you need a conventional blade mower for maintained lawn turf; the Greenworks 60V self-propelled mower has a 21-inch lawn-mower deck.
Choose this Earthquake for trimming and brush clearing where a walk-behind string mower and adjustable line thickness suit the growth. It is not a conventional lawn mower, so consider the cutting-head format before choosing it for regular turf.

7. Casince 17-inch Cordless Mower
- Dimensions: 17.5"D x 17.5"W x 28"H
- Weight: 30 lb
Best for: Small-Lawn Cordless Push Mowing.
Why it ranks #7: The 30-pound cordless mower has a 17-inch deck and six cutting-height settings, but its listed features do not specify slope-oriented traction.
A 17-inch deck paired with six height settings from 1 to 3 inches gives the Casince cordless mower a useful range for routine small- and medium-lawn cuts. Its dual 20V 4.0Ah batteries support extended runtime, while a brushless motor supplies up to 1,200W maximum output.
The brushless motor runs at 3,000 RPM, a combination the product describes as helping maintain blade speed through routine residential grass. Six height choices let you tailor the cut within the listed 1-to-3-inch range, and the 17-inch deck covers a moderate swath. The two-battery setup is intended to extend runtime, making this a cordless option for homeowners who want to avoid a power cord while mowing.
- 17-inch cutting deck
- Six cutting heights from 1 to 3 inches
- Brushless motor rated at 3,000 RPM
- Two 20V 4.0Ah batteries
- The listed cutting-height range ends at 3 inches.
Skip it if you need a higher rough-cut setting; the Swisher WRC11524BS lists a cutting-height range up to 4.75 inches.
The Casince fits small and medium residential lawns where cordless operation, a 17-inch deck, and several height choices meet the mowing needs. Its listed maximum cutting height is 3 inches, so check that range against your preferred finish.

8. Greenworks 40V 16-inch Mower
- Dimensions: 50.79"D x 18.9"W x 38.98"H
- Weight: 37.5 lb
- Material: Plastic
Best for: Lightweight Cordless Lawn Care.
Why it ranks #8: Its 37.5-pound weight and 16-inch deck suit smaller lawns, but the listed push design and features do not identify hill-specific drive or tires.
At 37.5 pounds, the Greenworks 40V push mower is 35% lighter than steel-deck mowers, which can make it easier to maneuver around a smaller yard. Its included 4.0Ah battery supports cutting up to one-third acre per charge, subject to grass conditions and operator technique.
The 16-inch cutting width and single-lever five-position height adjustment give you a compact setup with straightforward cut-height changes. Mulching and rear bagging provide two ways to handle clippings, and the included collection bag is ready for bagging. The battery and charger come with the mower, and its 40V battery platform works with more than 75 Greenworks 40V tools, offering compatibility across that system.
- 37.5-pound listed weight
- 16-inch cutting width
- Single-lever, five-position height adjustment
- Mulching and rear-bagging options
- The listed coverage is up to one-third acre per charge, varying with grass and technique.
Skip it if you need rear-wheel drive for slopes; the Greenworks MO60L424 60V mower lists self-propelled control and rear-wheel-drive traction.
This Greenworks suits owners of smaller lawns who value a lightweight cordless push mower, two clipping options, and an included battery and charger. Its stated coverage is limited to up to one-third acre per charge, depending on conditions.

9. LawnMaster 14-inch Corded Mower
- Dimensions: 26.9"D x 16.4"W x 12.8"H
- Weight: 12.7 kg
- Material: Metal
Best for: Corded Small-Yard Mowing.
Why it ranks #9: This 14-inch corded mower is lightweight and has 7.75-inch rear wheels, but its corded format and lack of specified hill traction limit slope suitability.
The LawnMaster’s 3,300 RPM electric motor runs without gas or batteries, making it a corded option for small-yard mowing. Its 14-inch cutting width and five height positions from 1.4 to 3 inches cover basic lawn-maintenance needs, while a 7-gallon collection bag gathers clippings.
A 14-inch cutting width keeps the mower compact for smaller areas, and five height settings let you adjust the cut within the listed 1.4-to-3-inch range. The 7.75-inch rear wheels support navigation around the lawn, while the collection bag contains clippings for a tidier finish. Because it uses corded electric power rather than gas or batteries, operation requires access to a power cord throughout mowing.
- 3,300 RPM electric motor
- Five cutting heights from 1.4 to 3 inches
- 7-gallon collection bag
- 7.75-inch rear wheels
- Corded operation requires a power cord during mowing.
Skip it if you need cordless operation across a yard without a cord; the Greenworks 40V 16-inch mower includes a battery and charger.
This LawnMaster suits small yards with access to a power cord, where its collection bag and adjustable cutting height match the routine. The corded design limits how far you can mow from the power source.

10. LawnMaster 20-inch Reel Mower
- Dimensions: 27.13"D x 18.23"W x 10.63"H
- Material: Metal, Plastic
Best for: Quiet Manual Lawn Maintenance.
Why it ranks #10: The manual push reel design and 10-inch front wheels suit maintained grass, but the product lists no powered drive or hill-focused traction.
The LawnMaster’s motorless five-blade reel cuts grass with a scissor-like action, avoiding gas or battery power for straightforward lawn maintenance. Its 20-inch cutting width and 10-inch front wheels support maneuvering around a yard, while nine height positions provide options from 1.3 to 2.6 inches.
Nine cutting positions let you select a height within the mower’s 1.3-to-2.6-inch range, which helps tailor the finish to the lawn. The 20-inch width covers a broad pass for a push reel mower, and the 10-inch front wheels are specified for maneuverability. Because the design uses neither gas nor batteries, operation avoids those power sources, though the mower relies on pushing rather than a motorized drive.
- Motorless five-blade reel design
- 20-inch cutting width
- Nine height positions from 1.3 to 2.6 inches
- 10-inch front wheels
- Manual push operation requires the user to supply the mowing effort.
Skip it if you want self-propelled assistance on slopes; the Greenworks MO60L424 lists rear-wheel drive and adjustable pace.
This LawnMaster suits owners of lawns that can be maintained with a manually pushed reel mower and a cut within its stated height range. Its motorless operation is a poor fit if you need powered assistance on slopes.

View on AmazonMatch the mower to the vegetation, not just the slope
A mower built for brush clearing is not automatically the best tool for routine lawn grass on a hill. The Swisher Predator is a rough-cut machine with a 24-inch deck that clears saplings up to 1.5 inches, while the MechMaxx is a 27-inch flail mower with tracks specified for rough terrain. By contrast, the Greenworks 60V and YARDMAX are lawn-mower formats, with traction-related features aimed at mowing grass.
The Earthquake models use string cutting heads for weeds and brush rather than conventional lawn blades. Choosing the wrong category can leave you with an unsuitable cut or an awkward machine for the terrain.
Before selecting by deck width alone, identify whether you need a lawn finish, tall-weed trimming, or rough vegetation clearance. The vegetation and slope conditions work together: a machine that can cut a sapling may still be more equipment than a maintained lawn needs.
Traction features do not establish a safe slope limit
None of these listings provides a maximum safe slope angle, so traction claims cannot be treated as permission to mow any particular incline. The MechMaxx listing says rubber tracks provide stability on slopes and rough terrain; Greenworks specifies rear-wheel drive for slopes; and YARDMAX highlights aggressive spiked tire tread. Those are meaningful differences, but the product data does not establish how steep, wet, or uneven a site each can safely handle.
A separate trap is assuming that a self-propelled drive removes the need to control the mower: the Swisher weighs 252 pounds and the MechMaxx 374 pounds, making it important to consider handling and safe maneuvering as well as drive type. Consult each operator’s manual for slope limits and operating instructions, and do not infer slope capability from wheel or track design alone.
How to Choose a Walk-Behind Mower for Hills
Traction and drive
Look first for traction and drive details that fit the direction and condition of your slope. The MechMaxx has rubber tracks described for slope and rough-terrain traction; the Greenworks 60V uses rear-wheel drive and adjustable pace; and the YARDMAX combines front-wheel drive with aggressive spiked tread and six CVT speeds. The Swisher adds self-propulsion and large pneumatic chevron tires for uneven terrain.
The Greenworks and YARDMAX are lawn-mower choices for maintained grass, while the MechMaxx and Swisher target rougher conditions. If your hill is a lawn, prioritize a manageable pace and the mower’s stated drive configuration.
If it is rough ground, the track or rough-cut formats may fit better. None of the listed data sets a safe slope angle.
Cutting width and vegetation
Choose a cutting system and width that match both the growth and the space you need to maneuver. Listed widths range from the 14-inch LawnMaster electric mower to the MechMaxx’s 27-inch flail deck; the YARDMAX and Swisher are 22-inch and 24-inch respectively. Width alone does not indicate hill performance.
The Earthquake string mowers cut a 22-inch swath and are described for weeds, trimming, and brush, while the Swisher rough-cut mower clears saplings up to 1.5 inches. For maintained lawn grass, the 21-inch Greenworks or 22-inch YARDMAX are more directly suited formats.
Narrower decks may better suit tighter areas; wider rough-cut decks fit larger, more open clearing tasks.
Power source and operating weight
Consider whether your job suits battery, corded, or gas power, and weigh that choice against the machine’s listed mass. The battery options include the 65-pound Greenworks 60V and the 40-pound Earthquake 60V string mower; the latter includes two 4Ah batteries and lists up to 90 minutes of runtime. The Greenworks 40V weighs 37.5 pounds, while the corded LawnMaster is listed at 12.7 kg.
At the heavier end, the Swisher weighs 252 pounds and the MechMaxx 374 pounds. Lighter formats may suit smaller maintained lawns and easier handling, while the heavier tracked or rough-cut machines are intended for demanding vegetation.
Battery runtime and weight do not by themselves establish suitability for a particular incline.
Which mower fits my hilly yard?
For rough slopes where track traction and brush-capable cutting matter, choose the MechMaxx 27-inch Flail Mower; its listing specifies rubber tracks for slopes and rough terrain. For a maintained lawn and battery power, the Greenworks 60V 21-inch Mower offers rear-wheel drive, adjustable pace, and two included batteries. The YARDMAX 22-inch Select PACE is another lawn-focused option, with aggressive spiked tread and six CVT speed settings.
If the job is dense undergrowth rather than lawn grass, the Swisher Predator Rough Cut clears saplings up to 1.5 inches and has pneumatic chevron tires. For weeds and brush trimming, consider either Earthquake string mower.
Check the operator’s manual for slope limits before use: the listed traction features do not specify a maximum safe incline.
Frequently Asked Questions
How steep a slope is safe to mow with a walk-behind mower?
There is no universal safe slope limit provided for these mowers. Check the operator’s manual for the specific model’s limits and instructions before mowing. The listed traction features can help describe a mower’s intended use, but they do not establish a maximum safe incline.
Should I mow across or up and down a hill?
Follow the mower’s manual, since safe mowing direction can vary by machine and conditions. Do not assume a listed drive or traction feature makes either direction safe. If the slope feels difficult to control, stop and choose a safer approach rather than continuing.
When should I avoid mowing a wet or slippery slope?
Avoid mowing when wet grass, mud, or other slippery conditions could reduce footing or mower control. Wait until the ground and grass are dry enough for secure footing and predictable handling. If conditions remain slick, postpone the job and consult the mower’s operating instructions.
What should I look for when mowing maintained grass on hills?
For maintained grass, consider the Greenworks 60V 21-inch mower, which specifies rear-wheel drive for slopes and adjustable pace. The YARDMAX 22-inch Select PACE is another lawn-focused option, with aggressive spiked tread and six CVT speed settings. Check each manual for slope limits before use.
Which mower suits dense undergrowth better than lawn grass?
For dense undergrowth, the Swisher Predator Rough Cut is listed as clearing saplings up to 1.5 inches and has pneumatic chevron tires. For weeds and brush trimming, either Earthquake string mower is an option. These uses differ from mowing maintained lawn grass, so match the machine to the vegetation.
Final Words
For rough slopes with brush-capable cutting needs, the MechMaxx 27-inch Flail Mower is the strongest listed choice: its rubber tracks are described as providing slope and rough-terrain traction and stability. For maintained grass, consider the Greenworks 60V 21-inch mower or the YARDMAX. Choose the Swisher for dense undergrowth, or an Earthquake string mower for weeds and brush.
Always check the manual’s slope limits before use.
