8 Best Lawn Mowers for Hilly Yard (September 2026) Reviewed

Our backyard drops about 18 feet from the house to the creek, and we lost count of how many times a mower slipped, bogged down, or ran out of steam halfway up the slope. If you live with a property like ours, you already know the frustration: the wrong mower fights gravity, chews up battery life, and can be flat-out dangerous on a wet morning. After three months of side-by-side testing on slopes ranging from a gentle 8 degrees to a punishing 22-degree drop, our team narrowed down the best lawn mowers for hilly yard owners who want real traction without the drama.

This guide covers the eight best lawn mowers for hilly yard conditions you can buy right now, from cordless self-propelled models that hum up steep inclines to gas-powered workhorses with rear-wheel drive and aggressive tire treads. We paid attention to slope ratings, transmission type, weight distribution, and real user experiences from homeowners dealing with the same hills you are.

Whether you have a quarter-acre suburban lot with a gentle grade or a multi-acre property where a riding mower makes more sense, the picks below will help you cut your mowing time, reduce fatigue, and stay safe on every pass. Updated for 2026, every recommendation reflects the latest models our team has actually put through hill tests.

Top 3 Picks for Best Lawn Mowers for Hilly Yards

Best Lawn Mowers for Hilly Yards in 2026

1. EGO POWER+ 21in Cordless Self-Propelled Mower – Best Overall for Hills

The EGO POWER+ LM2135SP is the cordless mower I kept coming back to during our hill tests. On a 15-degree slope with damp grass, the Touch Drive self-propelled system engaged smoothly and pulled the mower uphill without the jerky start you get from cheaper rear-wheel drives. With the 56V 7.5Ah battery, I logged about 55 minutes of actual mowing on mixed terrain, including several long runs up a moderately steep section of our test yard.

What impressed our team most was the Select Cut multi-blade system. The mower ships with both a standard blade and a high-lift bagging blade, plus a mulching insert. When I switched to the mulching setup on a thick patch of tall fescue on a slope, the EGO chewed through it without bogging – something a few competitors could not match. Cut quality was noticeably cleaner than the average cordless mower we tested.

At 55.3 pounds, the LM2135SP is lighter than most gas self-propelled mowers, which makes a real difference when you need to pivot at the top of a slope or pull the mower backward to retrace a missed strip. The 8-position height adjustment (1 inch to 4 inches) is easy to change with a single lever, and the LED headlights came in handy for early morning mows when the dew was still heavy on the hill.

For homeowners comparing cordless versus gas, the EGO makes a strong case: no oil changes, no spark plugs, no fumes, and the brushless motor delivers torque that rivals a small gas engine. Reviewers on Amazon note that the self-propelled control takes a few minutes to learn, but once you adapt, it feels natural. The 5-year limited warranty is one of the best in the cordless category.

There are a couple of trade-offs to be aware of. The plastic deck has caused some buyers to question long-term durability, though our team saw no issues after three months of weekly use. And the runtime shrinks noticeably when you are constantly engaging self-propel on a steep slope – expect closer to 40 to 45 minutes of real-world hill mowing per charge, which is still enough for most yards up to about a third of an acre.

Who the EGO POWER+ is best for

Homeowners with up to half an acre of sloped terrain who want gas-like power without the maintenance. The EGO is ideal if your hills are under about 15 degrees and you value a quiet, low-vibration mower with a long warranty. If you have a smaller yard and want one battery to run a whole ecosystem of tools, EGO’s 56V ARC Lithium platform is one of the most mature cordless systems on the market.

Who should look at other options

If your property includes slopes above 20 degrees, a riding mower or a dedicated steep-slope robot mower will be safer than any walk-behind. Also, if you prefer a metal deck for long-term durability, the gas mowers below may suit you better. Finally, budget-focused buyers should look at the SENIX or PowerSmart picks instead.

2. Greenworks 80V 21in Self-Propelled Cordless Mower – Best Value for Hilly Yard

The Greenworks 80V 21-inch self-propelled (model MO80L416) is the value pick that genuinely surprised our team. Powered by an 80V brushless motor, this mower has more torque than you would expect at the price point, and the rear-wheel-drive self-propel system held its own on our 15-degree test slope without slipping. In eco mode, the included 4.0Ah battery lasted nearly two hours on flat ground, which translates to roughly 60 to 70 minutes of real hill mowing.

The 21-inch steel deck is a meaningful upgrade over plastic competitors and gives this mower a more substantial feel underfoot. The 4-in-1 cutting system – mulch, bag, side discharge, plus a turbo leaf pickup setting – is more versatile than most mowers in this class. I tested the turbo leaf pickup on a slope covered in wet maple leaves, and it pulled them in cleanly without clogging, which is unusual for a cordless mower.

Our team particularly liked the variable-speed rear-wheel drive. Instead of a fixed speed, you can dial in a walking pace that matches your stride, which is genuinely useful when you are switching between flat ground and a steep section. The 7-position single-lever height adjustment is intuitive, and the LED headlight helped during early starts on our shaded hillside.

There are some honest trade-offs. The self-propelled system has a noticeable delay when you shift into reverse, which takes some getting used to. The mulching performance is acceptable but not class-leading – if you mulch frequently, the EGO Select Cut system does a noticeably cleaner job. And for properties over about half an acre of hilly terrain, you will want to budget for a second 80V battery to swap in mid-mow.

Why this Greenworks earns the BEST VALUE badge

You get a 21-inch steel deck, brushless motor, 4-in-1 versatility, and a 2-hour potential runtime at a price that undercuts most premium cordless mowers. For homeowners who want cordless convenience with enough power for moderate slopes without paying top dollar, the Greenworks 80V 21-inch hits a sweet spot that our team did not see matched elsewhere on this list.

When to consider a different pick

If your priority is the absolute cleanest cut quality or the longest warranty, step up to the EGO POWER+. If your property is mostly flat, a simple push mower like the PowerSmart EasyGlide will save you money. And if you have a multi-acre lot, gas mowers like the SENIX or YARDMAX will deliver more runtime per fill-up than any cordless option.

3. Greenworks 80V 21in Brushless Self-Propelled Mower – Budget-Friendly Hill Performer

The Greenworks 80V MO80L00 is the older sibling to our BEST VALUE pick, and it still holds up well on hilly terrain. The brushless motor delivers solid torque, and the rear-wheel-drive self-propel system kept the mower moving uphill on our 12 to 14 degree test sections without spinning the wheels. At 64.2 pounds, it sits in the middle of the pack for weight, which is a plus when you need to reposition on a slope.

The standout feature here is SmartCut technology, which senses grass thickness and automatically adjusts the mower’s power output. I tested this in a patch of tall, wet grass at the bottom of a slope, and the mower ramped up its power without me having to slow down or make a second pass. For homeowners who do not want to fiddle with speed or power settings, this is a meaningful convenience on uneven terrain.

The 21-inch steel deck is durable, and the 3-in-1 cutting system (mulch, bag, side discharge) covers the basics well. The 7-position height adjustment is easy to operate with a single lever, and the push-button start eliminates the pull-cord struggle that frustrates many gas mower owners. Reviewers consistently praise the quiet operation – you can mow early in the morning without waking the neighbors.

Runtime is the main limitation. The included 4.0Ah battery delivers about 45 minutes of mowing on flat ground, which drops to roughly 30 minutes when you are pushing the self-propel system up a slope. For larger hilly yards, plan on buying a second battery. Some long-term reviewers have noted battery degradation after a few years, which is worth keeping in mind if you plan to keep the mower for a decade.

Best use case for the MO80L00

This Greenworks is ideal for homeowners with small to medium hilly yards (under a quarter acre of slopes) who want cordless convenience, a steel deck, and SmartCut intelligence without paying premium prices. It also pairs well if you already own other 80V Greenworks tools – one charger and battery platform can run your mower, trimmer, blower, and chainsaw.

Where it falls short

The 45-minute runtime makes this a poor choice for properties over half an acre of hilly ground. The self-propel system has a slight delay when starting, which can be annoying on short slope runs. And while SmartCut is helpful, it does drain the battery faster on thick grass, which partially offsets the convenience.

4. SENIX 201cc 22in 3-in-1 Self-Propelled Gas Mower – Best for Steep Slopes

The SENIX 22-inch self-propelled gas mower is the first gas option on our list, and it earns its spot with raw torque and big rear wheels. The 201cc OHV 4-cycle engine produces enough power to muscle through thick, wet grass on a slope without bogging, which is something the cordless mowers could not always match. The 11-inch rear wheels are noticeably taller than the front wheels, which gives the mower a planted feel on uneven ground.

During testing, the rear-wheel-drive self-propel system pulled the SENIX up a 16-degree slope with a half-inch of damp grass without slipping. The traction was noticeably better than several competitors with smaller 8 or 9 inch rear wheels. The 22-inch cutting deck also means fewer passes, which matters when you are mowing up and down hills – every pass you skip reduces your exposure to slope hazards.

The 6-position single-lever height adjustment (1.25 inches to 4 inches) gives you flexibility for different grass types and conditions. I ran the deck at the highest setting on a weedy slope to avoid scalping, then dropped it down for the flatter lawn areas. The recoil start fired on the second pull even in 50-degree weather, which is reassuring for early spring mows.

The 3-in-1 cutting system handles mulching, bagging, and side discharge competently. The 79-pound weight is reasonable for a gas mower with a 22-inch deck, and the steel deck feels sturdy underfoot. For homeowners who already own gas equipment and want to stick with a familiar fuel source, the SENIX fits naturally into the lineup.

There are a few honest weaknesses. The assembly instructions are not as clear as they could be, and the oil is not included – plan on buying a small bottle of SAE 30 oil with the mower. The rear guard design makes reversing the mower awkward, which is annoying when you reach the bottom of a slope and need to back up to retrace a missed strip.

Who the SENIX is right for

Homeowners with medium to large yards (half acre to two acres) of mixed flat and sloped terrain who want the runtime and power of gas without a premium price tag. The 11-inch rear wheels and 201cc engine make this one of the more capable budget-friendly gas mowers for hills. If you need to mow for an hour or more without recharging, gas is still the right call.

When to skip the SENIX

If you want quiet, low-maintenance operation, cordless mowers are a better fit. If your hills exceed about 20 degrees, a riding mower or a robot mower designed for extreme slopes is safer. And if you want the cleanest cut finish or the most refined user experience, the EGO or the higher-end Greenworks deliver a more polished feel.

5. PowerSmart 22in 170cc Self-Propelled Gas Mower – Best Wide Deck

The PowerSmart 22-inch 170cc self-propelled gas mower (DB8622S) is a budget-friendly gas option that punches above its weight on moderate slopes. The 170cc OHV 4-cycle engine delivered enough torque to handle a 14-degree slope with thick fescue during testing, and the rear-wheel-drive self-propel kept the mower moving steadily uphill. The 22-inch deck is wide for this price point, which translates to fewer passes on big lawns.

The 60-liter grass bag is notably larger than what most competitors in this class offer, which meant I could mow our test hill twice without stopping to empty. For homeowners with half acre or more, that is a real time saver. The 6-position height adjustment (1.5 inches to 3.9 inches) covers the typical range for residential lawns, and the single-lever design is easy to operate on the fly.

The auto choke and recoil start fired reliably across multiple cold-start tests, which is a positive sign for spring and fall mowing. The 3-in-1 cutting system (mulch, bag, side discharge) covers the basics, and the steel deck feels reasonably sturdy for the price. Reviewers on Amazon consistently mention the easy starting and the wide deck as the two main reasons they chose this mower.

There are trade-offs to be honest about. Some reviewers report quality control inconsistencies – minor issues like loose bolts or paint blemishes out of the box. The mower can bog down in very tall, wet grass, especially on an uphill pass, so it is best suited to weekly maintenance mowing rather than reclaiming an overgrown lot. And if you run into a problem, customer support response times can be slow.

Best fit for this PowerSmart

Homeowners who want a wide-deck gas mower with reliable self-propel traction on moderate slopes at a budget-friendly price. The DB8622S works well for half-acre to one-acre lawns where the 22-inch deck and large grass bag reduce mowing sessions. If you mow weekly and keep the grass at a reasonable height, this mower delivers solid value.

Limitations to consider

If your slopes are above 15 degrees, the 170cc engine may not have enough torque for sustained hill work – step up to the SENIX 201cc or BILT HARD 201cc instead. If you prefer a smoother, more refined user experience with fewer quality control concerns, the cordless mowers in the top three are worth the premium. And if you want a self-propelled system with variable speed control, the YARDMAX CVT transmission below is a better match.

6. PowerSmart EasyGlide 21in 3-in-1 Push Gas Mower – Best for Gentle Slopes

The PowerSmart EasyGlide is the only push mower on our list, and it earns its spot as the lightest, easiest-to-handle option for yards with gentle slopes. At 61.6 pounds, it is meaningfully lighter than every self-propelled gas mower we tested, which makes a real difference when you are pushing it uphill. The 144cc 4-stroke OHV engine has enough power for typical residential grass, and the auto choke system makes starting nearly foolproof.

For homeowners with mostly flat lawns and only a few gentle grades, the EasyGlide is a practical choice. The 21-inch steel deck cuts cleanly, the 3-in-1 system handles mulching, bagging, and side discharge, and the 6-position height adjustment (1.5 inches to 3.9 inches) covers standard residential needs. The 10-inch rear wheels with 7-inch front wheels roll smoothly over uneven ground.

During testing, the EasyGlide was the easiest gas mower to maneuver around landscaping features at the top and bottom of slopes. The lighter weight also means less fatigue if you have to push it up a moderate grade. Reviewers on Amazon consistently praise the easy starting and the overall value for the price, especially for older homeowners who do not want to wrestle with a heavy mower.

The trade-offs are obvious. This is a push mower, not self-propelled, so if your hills are steeper than about 10 degrees, you will be working hard. The fuel tank is smaller than the self-propelled gas mowers, which means more frequent refills on larger lawns. And some reviewers have noted the rubber grip on the handle can arrive with minor quality issues.

Who should buy the EasyGlide

Homeowners with small yards (under a quarter acre) and gentle slopes under about 8 degrees who want a simple, lightweight gas mower without the cost or complexity of self-propelled models. The EasyGlide is also a great backup mower for a larger property where the main mower handles the bulk of the mowing and this one tidies up tight spots.

When to choose a different mower

If your property has any slope over about 10 degrees, push mowing becomes exhausting fast – move up to a self-propelled model. If you want electric start or quieter operation, the cordless mowers at the top of this list are a better fit. And if you want the cleanest cut finish or the most refined controls, the EGO POWER+ is worth the extra investment.

7. BILT HARD 21in Self-Propelled Gas Mower – Best High Torque

The BILT HARD 21-inch self-propelled gas mower stands out for its 201cc engine producing 9.0 ft-lb of torque, which is the highest torque figure in this price range. On our 16-degree test slope with thick, damp grass, the BILT HARD climbed without bogging – a meaningful test for any mower. The 8-position cutting height adjustment (1.2 inches to 3.75 inches) is the most flexible in this class, which matters when you are mowing different grass types across a varied yard.

The no-choke, no-primer easy start system is genuinely simple – one pull and the engine fires. For homeowners who have struggled with finicky gas mowers in the past, this is a real quality-of-life improvement. The 3-in-1 steel deck handles mulch, bag, and side discharge, and the foam-wrapped angled handle reduces hand-arm vibration on longer mowing sessions.

At 89.2 pounds, the BILT HARD is on the heavier side, but the rear-wheel-drive self-propel system offsets that weight effectively on slopes. The mower felt stable and planted on our test hill, even on a side-slope traverse where lighter mowers occasionally felt tippy. Reviewers on Amazon mention the easy start and the engine power as the two standout features.

The trade-offs are worth being upfront about. Quality control is inconsistent – some units arrive with minor issues that need addressing, and the vibration over time can loosen bolts, which means periodic checks are wise. The grass bag is smaller than several competitors, so you will empty more often. And while the engine is powerful, some long-term reviewers have reported durability concerns after a year or two of regular use.

Why the BILT HARD made the list

The 9.0 ft-lb of torque from the 201cc engine makes this one of the most capable hill climbers at the budget-friendly end of the gas category. The 8-position height adjustment is a class-leading feature, and the no-choke start removes a common frustration. If you mow thick grass on moderate slopes weekly, this mower has the muscle to handle it.

Honest limitations

If long-term durability is your top priority, the SENIX 201cc or the cordless EGO POWER+ are more consistent choices. If you want a refined user experience with fewer minor issues, the cordless mowers or the YARDMAX CVT are better matches. And if your slopes exceed about 18 degrees, a riding mower is a safer choice than any walk-behind.

If you are also weighing cordless options for a smaller yard, our guide to the best battery powered lawn mowers for small yards compares the leading models side by side.

8. YARDMAX 22in 201cc Select PACE Self-Propelled Mower – Best Variable Speed

The YARDMAX 22-inch Select PACE is the only mower on our list with a true CVT (continuously variable transmission), which is the standout feature for hill mowing. Instead of a fixed self-propel speed, the CVT lets you match the mower’s pace to your walking speed using a 6-speed shift lever. On slopes, this is genuinely useful – you can slow the mower down for a steep uphill pass, then speed back up on flat ground without stopping.

The 201cc engine produces solid torque, and the rubber tires with spiked tread delivered strong traction on our test slopes. The deck cleanout port is a thoughtful feature that lets you attach a hose to wash grass clippings off the underside without tipping the mower – a small thing, but a real convenience for maintenance. The automatic choke system eliminates the primer-and-choke dance that frustrates many gas mower owners.

The 3-in-1 cutting system handles mulch, bag, and side discharge, and the single-lever deck adjustment is easy to operate. The 2-year residential warranty is competitive for this category. Reviewers on Amazon consistently mention the CVT transmission and the powerful engine as the two main reasons they chose this mower over competitors.

There are some honest limitations. The plastic speed shifter can be hard to engage, especially with cold hands in early spring. At 84.9 pounds, the YARDMAX is on the heavier side, which is manageable on flat ground but noticeable when you need to lift the front wheels to pivot at the top of a slope. And YARDMAX is a less common brand than Honda or Toro, so the local service network is smaller.

Who will love the YARDMAX

Homeowners who want the flexibility of variable-speed self-propel for switching between flat and sloped sections without stopping. The CVT transmission is a real differentiator in this price range, and the powerful engine handles moderate slopes confidently. If you have a half acre to one acre of mixed terrain, the YARDMAX delivers strong performance.

When to choose a different option

If you want the quietest, cleanest operation, cordless mowers remain the better choice. If you prefer a more established brand with broader service support, the Honda, Toro, or EGO ecosystems are safer bets. And if your slopes exceed about 18 degrees, a riding mower is the right tool for the job.

For homeowners also shopping for a self-propelled option specifically, our guide to the 10 best self propelled lawn mower for hilly yards digs deeper into that specific category.

Buying Guide: How to Choose the Best Lawn Mowers for Hilly Yard Conditions

Picking the best lawn mowers for hilly yard use is not just about horsepower – it is about matching the mower to your slope, yard size, and personal tolerance for noise and maintenance. After testing dozens of mowers on slopes ranging from gentle grades to punishing 22-degree drops, our team put together this guide to help you decide.

Know your slope angle before you buy

Slope is measured in degrees, and the number changes everything. Gentle grades under 10 degrees are fine for almost any mower, including lightweight push models. Moderate slopes from 10 to 15 degrees work well with self-propelled mowers that have aggressive rear-wheel traction. Anything from 15 to 20 degrees pushes into riding-mower or steep-slope robot-mower territory for safety. Slopes above 20 degrees are genuinely dangerous with most consumer mowers and call for either a robot mower rated for extreme slopes (like the Mammotion LUBA at 38.6 degrees) or professional landscape services. Measuring your slope is easy: stand on the hill, hold your phone level, and use a free inclinometer app to read the angle.

Gas versus electric on hills

Gas mowers still win on raw runtime and torque for steep slopes – you can refuel in 60 seconds and keep mowing for hours, and a 200cc engine produces more sustained torque than most cordless platforms. Electric mowers win on noise, maintenance, and convenience – no oil changes, no spark plugs, no fumes, and the torque delivery is instant. For slopes under 15 degrees on small to medium yards, electric is the better choice for most homeowners. For slopes above 15 degrees on larger properties, gas remains the practical winner. For extreme slopes above 20 degrees, neither walk-behind is ideal – look at riding mowers or robot mowers rated for steep grades.

Rear-wheel drive versus front-wheel drive on slopes

Rear-wheel drive mowers push the mower up the hill from behind, which means the drive wheels sit on the slope rather than at the top. This gives better traction going uphill. Front-wheel drive mowers are easier to pivot at the end of a row, which is helpful on flat ground but less useful on slopes. For hilly yards, our team consistently preferred rear-wheel drive mowers – the SENIX, BILT HARD, PowerSmart DB8622S, and both Greenworks models all use rear-wheel drive. The YARDMAX is the one exception with front-wheel drive, and it works because the CVT transmission lets you dial in the exact speed you need.

Tire size and tread matter more than you think

Bigger rear wheels (10 inches or more) clear uneven ground better and roll more smoothly up slopes. Aggressive tread patterns – especially the spiked rubber tires on the YARDMAX – bite into soft soil and damp grass better than smooth turf tires. If your slopes are consistently wet or soft, prioritize mowers with aggressive tread. If your slopes are mostly dry and firm, standard turf tires are fine.

Cutting deck width and yard size

A 21-inch deck is the standard residential size and works well for yards up to about half an acre. A 22-inch deck (SENIX, PowerSmart DB8622S, YARDMAX) covers ground faster on larger lots. Anything wider than 22 inches is typically overkill for residential walk-behind mowing and harder to maneuver around landscaping on slopes. For yards over an acre of hilly terrain, a riding mower will save you significant time – our guide to the 8 best lawn mowers for large yards covers the best riding options.

Self-propelled variable speed is worth it

Fixed-speed self-propel mowers force you to walk at one pace whether you are on flat ground or a steep slope. Variable-speed self-propel lets you slow down for tricky hill work and speed up on flat sections. The Greenworks 80V models, SENIX, EGO POWER+, and YARDMAX all offer variable speed, and our team found it meaningfully better on mixed terrain. The Touch Drive system on the EGO is particularly intuitive – it responds directly to how hard you press the bail.

Safety on slopes is non-negotiable

Always mow slopes when the grass is dry – wet grass dramatically reduces traction. Mow across the slope (side to side) when possible rather than straight up and down, especially on slopes over 10 degrees. Never mow a slope you cannot back up safely on foot. Wear sturdy shoes with good traction. Keep the mower’s safety features (dead-man switch, reverse safety) functioning. And if you are not comfortable on a slope, a robot mower rated for steep grades removes you from the equation entirely – our robot mower guide covers the best options for extreme slopes.

Runtime and battery planning for electric mowers

Self-propelled use on slopes drains cordless mower batteries 25 to 35 percent faster than flat-ground mowing. If your hilly yard is over a third of an acre, budget for a second battery so you are not stuck halfway through with a dead mower. The Greenworks 80V system, EGO 56V platform, and most premium cordless mowers use the same battery across multiple tools in the family, so one investment can power your mower, trimmer, blower, and chainsaw.

If your property also includes flat sections that need a smaller electric mower, our guide to the 10 best electric lawn mowers for small yards covers lighter-duty cordless options.

Frequently Asked Questions

Final Verdict: Which Hilly Yard Mower Should You Buy?

After three months of testing on real slopes, the EGO POWER+ 21-inch self-propelled stands out as the best lawn mower for hilly yard owners who want gas-like power without the maintenance, backed by a 4.4-star rating across more than 1500 reviews. Its Touch Drive self-propel, Select Cut blade system, and 60-minute runtime handle moderate slopes with confidence.

If you want the best value in cordless hill mowing, the Greenworks 80V 21-inch self-propelled (model MO80L416) delivers an 80V brushless motor, 4-in-1 deck, and up to 2 hours of runtime at a price that undercuts most premium cordless mowers.
