1. Greenworks 80V 21in Self-Propelled Lawn Mower
Best for: Steep slopes needing strong rear wheel drive control
The Greenworks 80V Self-Propelled mower uses rear wheel drive with variable speed control, which helps maintain steady footing and control on steep ground. It runs on an 80V brushless motor and includes a 4.0Ah battery that cuts up to 1/2 acre per charge. The sturdy 21-inch steel deck gives great durability, while built-in LED headlights let you finish yard work safely during low-light hours.
Because it relies on the Greenworks 80V battery system, this machine isn’t for buyers who already own tools from different cordless platforms. The heavier steel deck provides stability against tipping, but it also means the tool requires more effort to turn around if the drive is turned off.
Pros
- Rear wheel drive gives steady hill traction
- Brushless motor delivers high cutting torque
- Variable speed matches your walking pace
Cons
- Only works with 80V Greenworks tools
- Heavy steel deck adds overall weight
2. BILT HARD 21″ Self Propelled Gas Lawn Mower
Best for: Tough outdoor cutting needing strong gas power
The BILT HARD Self-Propelled Gas mower brings serious muscle to steep yards with its 201cc 4-stroke OHV engine producing 9.0 ft-lb of torque. Its single-speed self-propelled rear-wheel drive helps pull the weight of the mower forward smoothly across tall slopes. The machine offers a 21-inch steel deck with full 3-in-1 capability for bagging, mulching, or side discharge.
A single lever easily controls all 8 cutting heights, spanning from 1.2 inches to 3.75 inches. However, because it uses a single-speed drive, you can’t speed up or slow down the self-propel function to match your natural pace. This model isn’t for anyone seeking a zero-maintenance tool, as the gas-powered engine requires regular fuel and oil care.
Pros
- Strong 201cc engine tackles thick grass
- Rear-wheel drive assists up slopes
- Single lever sets 8 cutting heights
Cons
- Single-speed drive can’t be adjusted
- Requires regular gas and oil maintenance
3. Worx Cordless Lawn Mower
Best for: Large yards wanting smart battery speed adjustment
The Worx 40V 21-Inch push mower features IntelliCut technology, which automatically speeds up the blade in thick patches and slows down to save battery life in thin areas. It’s powered by two 20V 5.0Ah PowerShare Pro batteries alongside a brushless motor 2.0 that covers up to 1/2 acre. Built-in AeroDeck technology vents air through the deck to stop clumps from clogging the collection passage on hilly paths.
The collapsible handle allows simple vertical storage in tight garage spaces. Because it’s a push lawn mower without a self-propelled motor, pushing this 21-inch deck up steep inclines requires plenty of personal effort. This model isn’t suited for users who can’t push heavy outdoor machinery up hills by hand.
Pros
- IntelliCut sensors adjust speed to grass
- AeroDeck design prevents wet grass clogs
- Folds up for upright vertical storage
Cons
- Pure push design lacks drive assistance
- Demands manual effort on steep grades
4. AMERISUN 21″ Gas Lawn Mower
Best for: Homeowners wanting a basic lightweight gas push machine
The AMERISUN 21-Inch Gas mower relies on a 144cc 4-stroke OHV engine that starts smoothly with a standard recoil cord. Its 21-inch steel deck provides a broad cutting path while keeping the overall machine at a manageable 63 lb weight. For changing lawn conditions, a single lever controls 6 height adjustments from 1.5 inches to 3.9 inches.
The unit includes a foldable handle to make seasonal storage and shed parking very straightforward. It features a 2-in-1 mowing system for mulch and side discharge, meaning it can’t collect clippings into a rear bag. Since it’s a push mower without drive wheels, it isn’t for buyers with very steep banks who require self-propulsion.
Pros
- Lightweight frame weighs only 63 pounds
- Reliable 144cc 4-stroke gas motor
- Broad 21-inch steel cutting deck
Cons
- Has no rear bagging option
- Lacks self-propelled wheels for slopes
5. Greenworks 40V 16in Push Lawn Mower
Best for: Small slopes needing an ultra-light compact frame
The Greenworks 40V 16-Inch cordless mower is designed to be 35% lighter than steel deck mowers, making it exceptionally easy to lift, guide, and steer along tricky banks. It cuts up to 1/3 acre on a charge using its included 4.0Ah battery, which works with over 75 tools in the Greenworks 40V platform. A single top lever controls 5 height positions across both axles.
This unit supports 2-in-1 functionality for rear bagging and clean mulching. Its narrow 16-inch deck allows it to slip between tight landscaping borders, but it takes more passes to finish wide spaces. This model isn’t for large properties, as the 16-inch width and smaller battery capacity are built strictly for modest yards.
Pros
- Very light frame eases hill maneuvering
- Backed by a 3-year limited warranty
- Shares batteries with Greenworks 40V tools
Cons
- Small 16-inch cut takes more passes
- Completely lacks self-propelled drive wheels
6. Casince 17-Inch Cordless
Best for: Small properties needing extended dual-battery electric runtimes
The Casince 17-Inch Cordless mower utilizes two 20V 4.0Ah batteries to deliver up to 40 minutes of runtime, covering up to 5,380 square feet under test conditions. Its 1200W maximum output brushless motor spins at 3000 RPM to maintain steady blade speed through regular yard turf. The 14 kg lightweight body ensures moving the tool across grades stays manageable for most users.
It features a generous 50L collection bag that minimizes how often you have to stop and empty clippings. The 17-inch cutting deck adjusts across 6 height settings between 1 and 3 inches. Because the cutting width is relatively narrow and lacks drive assistance, this mower isn’t for owners of large, sprawling hillsides.
Pros
- Light 14 kg body reduces fatigue
- Large 50L grass collection bag
- Dual batteries give 40-minute runtime
Cons
- Manual walk-behind push design only
- Maximum cutting height stops at 3 inches
7. Litheli 18-inch 40V Brushless Lawn Mower
Best for: Mid-sized yards wanting low-vibration battery yard mowing
The Litheli 18-Inch Cordless mower is driven by a 40V brushless motor designed for reduced vibration, low noise, and steady cutting performance. It comes packaged with two 5.0Ah batteries, allowing you to swap packs quickly so you can finish yard chores without long waiting delays. Its 18-inch profile strikes a useful balance between broad cutting coverage and nimble handling around garden beds.
A simple hand control lets you set 6 height adjustment positions to suit different grass varieties and seasons. The lightweight build makes guiding the machine around yard corners simple. It lacks powered drive wheels, so this mower isn’t for buyers with severe hill inclines who need mechanical help pushing up slopes.
Pros
- Brushless motor offers reduced vibration
- Includes two high-capacity 5.0Ah batteries
- Balanced 18-inch width handles cleanly
Cons
- Has no powered drive wheels
- Demands manual pushing up steep inclines
Also Worth Considering
- PowerSmart 3-in-1 Gas Lawn Mower: This gas-powered option features an EasyGlide push setup and a 21-inch cutting deck with full 3-in-1 bagging, mulching, and side discharge capabilities.
- LiTHELi Inch Cordless Lawn Mower: This small 14-inch cordless push mower uses a 5.0Ah battery and brushless motor, offering 5 height settings for tight yards up to 3,000 square feet.
- LawnMaster ME1218X.01 Electric Lawn Mower: This corded electric walk-behind mower provides continuous 12-amp power through a 19-inch cutting deck for consistent yard cleanup.
Where These Overlap
The cordless battery models share very similar designs, using brushless motors, multi-position height levers, and bundled lithium-ion packs. In particular, the Casince 17-Inch Cordless and Litheli 18-Inch Cordless are close enough in cutting width and dual-battery setups that either handles smaller yards similarly. What truly separates this group is the drive system. The Greenworks 80V Self-Propelled and BILT HARD Self-Propelled Gas stand out completely from the push mowers because their rear wheels do the pulling. That single drive feature matters far more on steep slopes than slight differences in cutting deck widths.

FAQ
Why is rear-wheel drive better for mowing hilly yards?
When you walk up an incline, gravity shifts weight toward the back of the mower. Rear-wheel drive puts power directly into the rear tires where traction is highest. This prevents the drive wheels from spinning uselessly on slick turf.
Can I mow slopes with a push mower?
Yes, you can mow slopes using a manual push mower if the incline is mild and the machine is lightweight. However, steep hills require significant physical effort and can cause slips. A self-propelled model provides much better control and safety on harsh inclines.
How do dual-battery mowers help on larger yards?
Dual-battery mowers provide extended runtime by letting you run longer or swap fresh packs immediately. This ensures you can finish hilly properties without waiting hours for a single battery to recharge midway through your chore.
Conclusion
Selecting the right slope mower comes down to choosing between powered drive wheels for tough climbs or lightweight frames for simple steering. The models listed above give you dependable options for both gas-powered muscle and modern cordless battery convenience. Matching your yard’s incline to the right drive system ensures safer, easier lawn care all season long.
Once you’ve narrowed down your favorites, take a quick trip to a local dealer to test how the handles feel in your grip. It’s worth seeing the machine in person before you commit. You’ll feel much more confident tackling those tricky slopes once you’ve found a mower that’s truly comfortable to operate.
