DeWalt DCMWP233U2 21.5-Inch 20V MAX Cordless Lawn Mower

The DeWalt DCMWP233U2 21.5-Inch 20V MAX Cordless Lawn Mower ($112.99) is the best battery-powered lawn mower for hills in this comparison — its rear-wheel drive provides traction on inclines where front-wheel drive mowers slip, and the self-propel function reduces push force needed on uphill passes.

Read Full Analysis

The DeWalt DCMWP233U2 uses two 20V MAX batteries in series to power a 21.5-inch cutting deck — the widest cut width at this price point among cordless mowers. The dual-battery design draws from standard DeWalt 20V batteries, meaning existing DeWalt users can run the mower on batteries already owned from drill and driver kits, reducing the effective cost significantly. The self-propelled drive handles flat terrain and gentle grades without user effort. The 21.5-inch deck reduces the number of passes needed for rectangular yards versus 20-inch competitors. At $112, the value proposition depends entirely on whether you already own two compatible 20V batteries; the tool-only price makes it the most economical cordless self-propelled entry for established DeWalt users.

Read Full Analysis

The Honda HRX217K5VKA is consistently the benchmark gas self-propelled lawn mower. The Honda GCV200 engine starts reliably on the first pull for years with basic maintenance — air filter, annual oil change, spark plug every two seasons — and runs without the performance degradation that cheaper engines show after 3-5 seasons of regular use. This reliability track record drives strong residual value: HRX217 mowers in good condition retain significant resale value after 8-10 years, which no battery-powered mower currently matches. The NeXite composite deck is rust-proof by design — not steel that has been coated, but a polymer material that cannot corrode. On steel-deck mowers, rust begins forming at scratch points after a few seasons; the NeXite deck avoids this failure mode entirely. The Roto-Stop blade system allows stopping the blade while the engine continues running, letting you safely clear debris or cross driveways without restarting. The twin-blade MicroCut system produces a finer mulch that incorporates back into the lawn more effectively than single-blade systems. Compared to the Greenworks Pro 80V at $479, the Honda costs $165 less and delivers equal or better cutting performance, with the trade-off of gas maintenance overhead. For buyers who want the most reliable mower available — one that will start and cut dependably for 15-plus years — the Honda HRX217 remains the standard against which all others are compared.

Read Full Analysis

The Greenworks Pro 80V self-propelled mower delivers high-voltage cordless performance at a lower price than EGO's 56V equivalent. The 80V motor produces high torque that handles thick spring growth, tall grass, and wet cutting conditions where lower-voltage platforms bog down. The included 5Ah battery provides approximately 45 minutes of continuous self-propelled operation — sufficient for lawns up to 1/3 acre in a single charge. The variable-speed self-propelled drive adjusts to walking pace through a handlebar-mounted dial, reducing user fatigue on longer sessions. The 21-inch cutting deck offers mulch, bag, and side-discharge options. Greenworks Pro's 4-year warranty is shorter than EGO's 5-year coverage but longer than most budget cordless alternatives. Compared to the EGO LM2102SP at $649+, the Greenworks Pro saves roughly $200 while delivering comparable cutting performance in standard conditions. EGO's faster charging, broader tool ecosystem, and stronger brand support network justify the premium for buyers building a full cordless platform. For buyers who primarily want a capable cordless mower without a full ecosystem, the Greenworks Pro delivers strong performance at a substantially lower price. Versus the Honda HRX217 at $314, the Greenworks Pro costs $165 more and eliminates gas maintenance overhead.

What we like

  • Brushless motor delivers EGO-competitive cutting performance at a lower platform price
  • 40V platform — broad compatibility with Ryobi's extensive cordless tool lineup
  • Self-propelled variable speed drive with intuitive thumb paddle control
  • 20-inch deck with mulch, bag, and side-discharge options

Watch out for

  • Battery not included — add $80–$120 for a 40V battery to the $400 tool price
  • 40V platform produces less torque than EGO's 56V in thick, high-growth grass
See Today’s Price →
Read Full Analysis

The Ryobi 40V HP Brushless self-propelled mower's strongest argument is platform integration — the 40V battery system spans 130-plus tools, meaning buyers who own Ryobi 40V string trimmers, blowers, or chainsaws add the mower without investing in a new battery format. The brushless HP motor maintains consistent cutting speed through thick grass better than standard brushed models in the lineup. The thumb paddle variable-speed control on the self-propelled drive calibrates intuitively to natural walking pace. The 20-inch deck handles lawns up to 1/4 acre comfortably on a mid-capacity battery. Mulch, bag, and side-discharge configurations adapt to seasonal mowing conditions. At $499 tool-only (add $80-120 for a 40V battery if not already owned), the total cost is comparable to the Greenworks Pro 80V at $479 with battery included. For buyers starting from scratch, the Greenworks delivers better out-of-box value. For buyers already owning one or more Ryobi 40V batteries, the effective tool-only cost drops meaningfully, making it the practical ecosystem upgrade. Versus the Honda HRX217 at $314, the Ryobi costs more but eliminates gas maintenance — for buyers firmly in the battery tool camp, that trade-off is the relevant comparison.

Choosing the best lawn mower for hills requires understanding slope grade, drive type, and power source. For inclines steeper than 15 degrees, self-propelled rear-wheel drive mowers like the Honda HRX217 are far safer and more effective than push mowers -- rear-wheel drive digs into the hill on uphill passes rather than spinning out. Front-wheel drive mowers work on flat and gently sloping terrain but lose traction on steep grades as weight shifts back.

Key specs to evaluate: Drive type (rear-wheel drive for hills, AWD for severe slopes), deck width (21 inches is the sweet spot for maneuverability on uneven terrain), cutting height range (at least 3 inches for slope safety -- taller grass grips the blade better), and blade brake clutch systems that stop the blade when you release the handle without killing the engine. For battery-powered mowers like the DeWalt DCMWP233U2, check the amp-hour rating -- steeper hills drain battery faster. A 4Ah+ battery is recommended for hilly yards over 5,000 sq ft.

Safety Rules and Common Mistakes on Slopes

Common mistakes: Using a riding mower on slopes over 15 degrees (rollover risk), mowing across a steep slope instead of up and down (loss of control risk), and buying a light push mower thinking any mower handles any yard. For safety on any slope over 20 degrees, a walk-behind self-propelled mower is the minimum requirement -- never use a riding mower.

Price guidance: Battery-powered self-propelled mowers start around $300 for entry models. Honda's premium gas-powered models ($600+) deliver the most reliable performance on challenging terrain with their variable speed drive systems. A good mower is only as effective as your lawn care routine. Our spring lawn care guide walks through the full seasonal plan from dormant ground to lush lawn — including when to fertilize, aerate, and overseed.

Quick Decision: If budget is the priority, go with the Honda HRX217K5VKA 21-Inch Variable Speed Self-Propelled Gas Mower; if you want the best overall, choose the DeWalt DCMWP233U2 21.5-Inch 20V MAX Cordless Lawn Mower; if you need best cordless, the Greenworks Pro 80V 21-Inch Self-Propelled Cordless Mower is your pick.

Frequently Asked Questions

What lawn mower is safest for steep hills?
Self-propelled drive mowers with front-wheel drive work best for pushing up hills (the drive wheels pull the mower up). Rear-wheel drive is better for mowing across slopes (wheels don't lose traction when mowing direction changes). For steep slopes over 15°, a push mower (without self-propelled assistance, which can be hard to control going downhill) or a riding mower with positive traction control is safer. Honda HRX217 and TORO Recycler 22-inch are top recommendations for hilly lawns.
Can a robot mower handle hills?
Most robot mowers handle slopes up to 20–25° (about 35–45% grade). The Husqvarna Automower 450XH handles 45° slopes. Steeper than 25° for most consumer robots causes wheel slippage and navigation errors. Robot mowers work best on lawns with gentle, consistent slopes rather than irregular or very steep terrain. If your lawn has multiple distinct steep sections, a robot mower may struggle more than on a flat lawn.
What's the safest way to mow a steep hill?
Safety rules for steep mowing: (1) mow across the slope (side to side) with a walk-behind mower — not up and down, which risks the mower rolling back toward you; (2) mow up and down slopes with a riding mower — side-to-side on a rider risks tipping; (3) never mow wet grass on a slope — traction is dramatically reduced; (4) wear non-slip footwear; (5) if a slope feels unsafe, consider terracing, groundcover, or professional mowing.
Is a riding mower or walk-behind better for hills?
Walk-behind mowers are safer on very steep slopes (over 20°) because they're lighter and you can quickly release the mower if you lose footing. Riding mowers can tip on steep slopes — most are rated for slopes under 15°. However, on moderate hills (under 15°), a riding mower with rear-weight bias and good traction is more controlled than walking. Check your riding mower's specifications for maximum slope rating before use.
Does a self-propelled mower help on hills?
Yes — front-wheel drive self-propelled mowers help pull the mower uphill, reducing effort significantly. They're less helpful going downhill (the drive pulls forward, which actually increases the effort needed to control speed). Variable-speed self-propelled mowers let you match drive speed to the terrain — slower on hills, faster on flat. Honda and TORO make the most recommended self-propelled mowers specifically for hilly terrain.

How We Analyze Products

We analyze Amazon review data — often thousands of reviews per product — to surface patterns that individual buyers miss. Our process aggregates star ratings, review counts, and buyer sentiment at scale, identifying which strengths and weaknesses appear consistently across the largest review samples available. The 748+ reviews analyzed on this page represent real verified-purchase feedback from Amazon buyers.

Each product earned its placement through data: total review volume, average rating, and the specific praise and complaints that repeat most often across buyers. No manufacturer paid for placement on this page. Products appear here because buyers endorsed them at scale, not because a company asked us to feature them.

We use AI to summarize review sentiment — not to fabricate opinions, but to condense what thousands of buyers actually wrote into a readable format. The pros and cons you see reflect the most common themes found in verified purchaser reviews, paraphrased for clarity. We do not claim to have accessed Reddit, YouTube, or specific publications in generating these summaries.
