A self-propelled lawn mower for hills is a walk-behind mower whose drive wheels supply the pushing force, so you steer instead of push. Rear-wheel drive or all-wheel drive is the deciding feature, and the best self propelled lawn mowers for hills pair a rear drive wheel with a speed control you can slow down for the grade.
That matters more than any brand name. On a hill you are fighting gravity, not just grass. As weight shifts backward going uphill, a front-wheel-drive mower loses contact under its drive wheels and spins instead of climbing, leaving you shoving a machine with no mechanical advantage.
We worked through ten self-propelled mowers on sloped ground, comparing drive systems, rear wheel diameter, weight, deck size and speed control rather than just cut quality. Three questions narrow the list faster than any spec sheet: gas or battery, how steep the worst grade is, and how much of it is side slope versus a straight climb. Updated for 2026.
Top 3 Picks for Hilly Yards in October 2026
Our three standouts cover the most common hill situations: a graded lot where torque and control matter, a buyer who wants traction without gas, and a large property where battery capacity decides whether you finish in one session.
EGO POWER+ LM2135SP
- 7.0 ft-lbs torque
- Touch Drive self-propel 0.9-3.1 mph
- Up to 60 min runtime
The EGO leads because it puts its torque where a hill needs it and weighs 55.3 pounds, lighter than the gas machines here. The Greenworks 80V is the traction value pick, with rear-wheel drive and load-sensing power. The PowerSmart covers the gas route with rear-wheel drive and a Briggs and Stratton engine that starts without fuss.

1. EGO POWER+ 21 inch LM2135SP: Best Overall for Hills
EGO POWER+ 21″ Cordless Electric Lawn Mower Kit, Self-Propelled – LM2135SP
7.0 ft-lbs torque
56V 7.5Ah battery, up to 60 min
Select Cut blades
55.3 lb
Pros
- 7.0 ft-lbs of torque climbs without bogging
- Touch Drive self-propel with a 0.9-3.1 mph speed dial
- Up to 60 minutes on the included 7.5Ah battery
- Select Cut blades switch between mulching and high-lift bagging
Cons
- At 55.3 pounds it is bulky in tight spaces
- One battery means pauses on larger hilly lots
Torque is what you feel on a hill, and 7.0 ft-lbs is why this is our pick. Reviewers report the self-propel handles inclines without stalling, and that the drive is what makes a sloped lawn manageable rather than a workout.
The Touch Drive system does the work. Press the palm pad and the drive engages, then the fingertip dial runs self-propel speed from 0.9 to 3.1 mph. That low end matches a careful walking pace, which is the control owners ask for and rarely get.
Weight is the honest tradeoff, and here it is a feature. At 55.3 pounds it is the lightest machine in this roundup with a published weight, and lightness is control on a hill.
Select Cut swaps the lower blade for mulching, high-lift bagging, or extended runtime. On a slope you usually want the runtime blade, because self-propelling uphill draws power faster than self-propelling flat.
Check the runtime math first
Up to 60 minutes is the flat-ground figure. Self-propelling uphill and cutting thick grass both cut into that, so owners with more than a quarter acre on a slope generally add a second 56V ARC battery, because the kit ships with one.
Where it is the wrong choice
A 21-inch deck is right for tight side slopes, but it means more passes on open lawn. The light build is also less forgiving of a hidden rock than a heavy steel deck.
2. Greenworks 80V 21 inch Self-Propelled: Best Value on a Grade
Greenworks 80V 21″ Brushless Cordless (Self-Propelled) Lawn Mower (75+ Compatible Tools), 4.0Ah Battery and 60 Minute Rapid Charger Included
80V 4.0Ah, up to 45 min
Rear-wheel drive, variable speed
SmartCut load sensing
64.2 lb
Pros
- Rear-wheel drive holds traction on steep inclines
- SmartCut load sensing adapts power to grass density
- One-lever 7-position height adjustment
- Self-propel runs with the blade off for transport
Cons
- Self-propel motor takes 2-3 seconds to spin up
- Slowest self-propel setting is still quick for slow walkers
- Rear wheels can jam when grass builds around the drive
This is the model owners cite most for genuinely steep ground. Rear-wheel drive with variable speed control is the textbook hill layout, and one long-term owner reports mowing 35-degree ditch banks with it. That is anecdotal rather than measured, but it matches the drive design.
SmartCut load sensing is the quiet advantage. The mower reads grass density and adjusts power automatically, which on an incline is the difference between climbing through a thick patch and bogging in it.
Two speed complaints come up repeatedly. The motor takes two to three seconds to spin up, and the lowest setting is still faster than a slow walker’s pace. One feature helps on hills specifically: self-propel runs with the blade off, so you can drive to the top of a slope without hand-carrying 64 pounds uphill.
Why the 4.0Ah battery is the weak point
Roughly 45 minutes of runtime with a 60-minute recharge. On a hilly lot, plan to swap at the top of the hill rather than mid-climb. Extra 80V packs add up across seasons, which is the running cost to weigh against gas.
Watch the wheel wells in long grass
Owners report rear wheels jamming when grass builds around the drive. On a slope where traction is already at its limit, a jammed drive wheel is worse than on flat ground because you cannot easily bail out of the pass.
3. Greenworks 60V 21 inch Dual Battery: Best for Large Hilly Lots
Greenworks 60V 21in Self-Propelled Lawn Mower, (2) 4.0 Ah Battery Kit
Two 4.0Ah 60V batteries
Rear-wheel drive, variable speed
LED headlight
4-in-1 deck, 65 lb
Pros
- Two 4.0Ah batteries cover up to 3/4 acre per charge
- Rear-wheel drive traction on slopes and thick grass
- Runs 3x quieter than gas with instant start
- Ultra-bright LED headlight
- 4-year tool and battery warranty
Cons
- 65 pounds is heavy for a cordless walk-behind
- Deck bottoms out at 1 inch which can scalp uneven ground
Two batteries change the hill experience on a large property. With both 4.0Ah packs included, stated coverage is up to three-quarters of an acre per charge, and the second pack removes the mid-mow recharge that usually lands on the steepest part of the yard.
The drive is rear-wheel with on-the-go variable speed, the correct pairing for slopes, and buyers single out the slope handling as their reason for choosing it.
The 60V platform also works with 75-plus other Greenworks tools, so the mower introduces no new battery ecosystem. The 4-year tool and battery warranty runs longer than most here.
Weight is the drawback. At 65 pounds this is not a machine you casually lift over a retaining wall. Mass helps traction and works against you when you need to reposition.
Set the deck higher on uneven ground
The height range starts at 1 inch. A deck that low follows every rut and scalps the high points, which is worse for the lawn than leaving grass slightly long.
Who should skip this one
If your hills are short and sharp rather than long and graded, the dual-battery capacity is more than you need and 65 pounds is a real cost. A lighter machine you can turn quickly at the top of a slope suits a small yard better.
4. PowerSmart 22 inch 150cc Gas: Best Gas Mower on a Grade
PowerSmart 22-Inch Gas Lawn Mower, 150cc B&S Engine, Self-Propelled, 3-in-1 Mulching System, 6 Cutting Heights, Rear-Wheel Drive, Durable Steel Deck
Briggs and Stratton EX625 150cc
Rear-wheel drive on inclines
Steel deck, 6 heights
72 lb, gas
Pros
- Rear-wheel drive traction on incline slopes
- EX625 150cc engine with ReadyStart for easy starting
- Steel deck with single-lever 6-position height adjustment
- 1.4-bushel bag empties quickly
- Unlimited runtime
Cons
- 72 pounds is heavy to lift or carry
- Fuel mixing oil changes and pull-start upkeep
- Louder than any cordless option
Gas removes the battery question entirely, and on a hill that outweighs the extra maintenance. No charge time, no uphill runtime penalty, no capacity planning. Owners value the rear-wheel drive traction and the way the EX625 keeps pulling when grass thickens partway up a slope.
The USA-made Briggs and Stratton EX625 150cc with ReadyStart is why we would pick this over cheaper gas mowers. Starting is the most common complaint about budget gas models, especially on a grade where a failed first pull leaves you standing on a slope with a pull cord.
Cut quality is a real strength. Owners report a heavy-duty blade producing fine clippings, and the steel deck adjusts from 1.5 to 3.9 inches on a single lever. Ratings sit at 4.0 with roughly 15% one-star reviews, and complaints cluster around assembly and long-term durability rather than hill performance.
Start at the bottom, not the top
Run the mower down to the base of the slope under its own power, then climb. Starting at the top means the engine is loaded the moment it fires, which is when startups fail.
Understand what 72 pounds feels like
That mass is an asset for traction and a liability for recovery. If the drive loses grip on a damp slope, you are not casually dragging 72 pounds back onto the contour.
5. SENIX 22 inch 201cc Gas: Best for Rough, Rocky Ground
SENIX 201cc 22″ 3-in-1 Variable Speed Self Propelled Gas Lawn Mower
201cc 4-cycle OHV engine
Rear-wheel drive, 11 inch rear wheels
22 inch steel deck
79 lb
Pros
- 11-inch rear wheels roll over rough ground well
- Rear-wheel drive for slope traction
- 201cc four-cycle power for medium to large lawns
- 22-inch deck covers ground faster per pass
Cons
- Lowest average rating in this group at 3.9
- 79 pounds is demanding to maneuver on a slope
- Gas upkeep fuel storage and loud operation
Wheel size is this mower’s argument. The 11-inch rear wheels are the largest drive wheels in this roundup, and large rear wheels let a walk-behind roll over a rut, a tree root, or the lip of a drainage swale instead of stopping dead in it. Owners mowing rough ground point to exactly this.
The 201cc four-cycle OHV engine gives consistent power on medium and large properties, and the 22-inch steel deck covers more ground per pass than any 20-inch machine here.
We want to be straight about the rating. At 3.9 stars from 1305 reviews this is the lowest-scoring machine in the group, and 18% of reviews are one-star, with build quality and reliability over time as the recurring theme.
The hill hardware is still honest: rear-wheel drive, large rear wheels, a steel deck, and a variable-speed self-propel. This is a machine built with slopes in mind.
Where the 11-inch wheels pay off
They matter most when your slope is not a clean grade but broken terrain: a side yard with tree roots, a berm between two lawn levels, a shallow ditch that has washed uneven. Small wheels make every dip a hill.
Plan around the weight
At 79 pounds with a full steel deck and a four-cycle engine, this is heavy to control on an incline. It suits rough ground with moderate grades, not a smooth but very steep front lawn.
6. YARDMAX 22 inch 201cc CVT: Best for Pace Control
YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower, Black (YG2860)
CVT transmission, 6-speed lever
High-wheel front-wheel drive
201cc gas, 22 inch
84.9 lb
Pros
- CVT gives stepless speed matching to your pace
- High-wheel drive with aggressive spiked rubber tires
- Automatic choke starts without priming
- 2-year warranty with 5-year spare part availability
Cons
- Front-wheel drive is the weakest choice on a hill
- 84.9 pounds is heavy on uneven ground
- Gas maintenance and pull-start operation
The transmission is genuinely special. A continuously variable transmission with a six-speed shift lever gives stepless speed matching to your walking pace, which is exactly the control a side slope demands. There is no discrete gear to hunt for mid-pass.
Buyers single out two things: the CVT speed control, and the high-wheel front-wheel drive with aggressive spiked rubber tires, which do provide real grip and raise ground clearance over uneven ground.
Now the honest part. It is front-wheel drive, and that is the configuration we told you to avoid on a hill. The spiked tires soften the weakness but do not change the physics: as mass shifts backward going uphill, the drive wheels unload. At 84.9 pounds it is also a heavy machine.
What the CVT gives you on a slope
Speed control is the second-most important hill feature after drive type, and this machine does it better than anything else here. Trimming the speed continuously means the mower tracks your contour instead of running away from you.
Where it falls down
On a steep, sustained climb the drive wheel can spin out, and you end up pushing a nearly 85-pound machine uphill, which is the scenario that ends with a mower running back down the slope.
7. SKIL PWR CORE 40 20 inch: Best for Light Handling
SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower Kit, Includes 6.0Ah Battery and Auto PWR JUMP Charger – SM4910C-11
40V 6.0Ah battery, up to 50 min
Variable-speed self-propel
20 inch deck, 7 heights
Light enough to lift one-handed
Pros
- Light enough to lift with one hand on a slope
- Variable-speed self-propel moves smoothly
- Up to 50 minutes of runtime per charge
- Push-button start with no pull cord
- Telescoping handle folds for storage
Cons
- 20-inch deck is narrower than 21- and 22-inch rivals
- One battery means downtime on bigger yards
- Handle must be fully extended and locked before it runs
Weight is the whole argument. Owners describe this mower as light enough to lift with one hand, and several users with arm, shoulder or foot limitations say the self-propel is what let them keep mowing. On a hill, a machine you can lift and reposition is one you will actually take onto a steep grade.
At 4.5 stars from 214 reviews this is the highest average rating in the group. The 40V 6.0Ah battery delivers up to 50 minutes, with owners reporting three-plus mows per charge on a quarter-acre lawn.
Two operational details catch people out. The handle must be fully extended and locked before the mower will run, and the self-propel lever needs releasing a moment before the end of a row to avoid a lock-up. Both matter when you are walking backward on a slope at the end of a pass. Buyers should also confirm their battery pack is not one of the units affected by an earlier battery fault recall on this model.
Best choice for back and mobility limits
If pushing a mower uphill is a physical problem rather than a convenience problem, light weight plus self-propel changes the equation. This is the machine here most likely to be usable by someone who cannot manage a 70-pound gas walk-behind on an incline.
The trade you accept
A 20-inch deck is narrower than the 21- and 22-inch machines, so open lawn takes more passes. On a small hilly yard under a quarter acre that is a good trade.
8. PowerSmart 20 inch Dual Battery: Budget Pick for Slopes
PowerSmart 20″ Self-Propelled Cordless Lawn Mower, Brushless Motor, 2 x 40V 4.0Ah Battery & Charger (MB2420SA)
Two 40V 4.0Ah batteries
Rear-wheel self-propel lever
20 inch deck, 6 heights
57.5 lb
Pros
- Rear-wheel self-propel adds traction on steep slopes
- Two batteries swap in seconds
- Brushless motor runs cooler and quieter
- 3-in-1 mulching bagging and side discharge
Cons
- 20-inch deck is the smallest cutting width here
- 7-inch wheels roll over uneven ground less smoothly
- 40V platform has fewer tool options
Rear-wheel-drive self-propel with two swappable batteries at the entry level of this group is unusual, and buyers cite the slope traction and the battery swap as their reasons. At 57.5 pounds it is also one of the lighter machines here, which is the combination a hill rewards.
The two 4.0Ah 40V packs swap in seconds, so one charges while the other runs. The brushless motor runs cooler and quieter than a brushed design, with less vibration through the handle on a long slope.
The 7-inch wheels are the weak point. Small wheels drop into ruts rather than rolling over them, which turns a bumpy side slope into a series of small climbs. On smooth, graded ground that is a non-issue; on broken terrain it is a constant irritation.
What the dual battery really changes
Runtime stops being a planning problem. With a pack charging while you mow, you can finish a slope in one session instead of splitting the work around a recharge.
Where the 40V platform limits you
40V systems support fewer cross-compatible tools than 60V or 80V platforms, so if you want one battery family across your yard equipment this is the wrong ecosystem.
9. BILT HARD 21 inch 201cc: Best for Easy Starting
BILT HARD 21″ Self Propelled Gas Lawn Mower – 201cc 4-Cycle OHV, 3-in-1 Bagging/Mulching/Side Discharge, 8 Adjustable Cutting Heights & Smooth Easy Start
201cc 4-stroke OHV engine
Rear-wheel drive self-propel
8 height positions
89.2 lb, gas
Pros
- Starts on the first pull with no choke or primer
- 201cc engine with 9.0 ft-lb of torque
- Rear-wheel drive self-propel
- Single-lever 8-position height adjustment
Cons
- 89.2 pounds is a real drawback on hills
- Spark plug wire failures cause no-start reports
- Build quality questioned by some reviewers
The no-choke, no-primer design matters most here, and on a slope it matters more than anywhere else. There is nothing to adjust before the first pull, so you are not fiddling with a carburetor while standing on a grade. Buyers repeatedly praise first-pull starting.
The engine produces 9.0 ft-lb of torque, and rear-wheel drive gives the correct traction layout for a climb. Height adjustment spans eight positions from 1.2 to 3.75 inches on a single lever, the widest range in the roundup.
At 89.2 pounds this is the heaviest machine we tested, and on hills that is not a small detail. Heavy means strong traction going up and very little ability to recover when a drive wheel loses grip. The rating is 4.3 from 111 reviews, the smallest base here, and a cluster of no-start reports traced to spark plug wiring is the most specific complaint.
Easy starting is a hill safety feature
Every restart on a slope is a moment you are standing on uneven ground with a machine that may move. A design that fires on the first pull removes the pull-cord attempts that turn a small stall into a recovery problem.
Be honest about the weight
If your grades are long and sustained, we would steer you toward something lighter. The 89-pound figure works against you any time you need to move the machine by hand rather than drive it.
10. AMERISUN 21 inch 170cc: Best High-Wheel Design
AMERISUN 21″ Self-Propelled Gas Lawn Mower, 170cc OHV Engine 3 in 1 Mower
170cc 4-stroke OHV engine
10 inch rear and 7 inch front wheels
21 inch 3-in-1 deck
Gas
Pros
- 10-inch rear wheels roll over hills and uneven ground
- 170cc engine holds up in tall thick grass
- 3-in-1 side discharge mulching and bagging
- 1.4-bushel catcher
- Quick and simple assembly
Cons
- 170cc is the smallest engine in this group
- No published variable speed so pacing is fixed
- 16% one-star reviews flag build quality
The high-wheel design with 10-inch rear wheels and 7-inch front wheels is why owners choose this machine, and they describe it as what makes hills and uneven ground manageable. Wheel size that large is a real hill advantage here.
Assembly is quick and simple, which owners mention as a genuine plus on a machine with a foldable handle and a heavy-duty steel deck.
The 170cc four-stroke OHV engine is the smallest displacement here, with less torque than the 201cc machines, and the self-propel has no published variable speed control, so pacing is fixed. On a grade that is a real limitation: you cannot trim the drive to match a careful side-hill walk. Ratings sit at 4.0 with 16% one-star reviews flagging build quality.
When fixed-speed self-propel is enough
On a short rise or a rolling grade rather than a sustained climb, fixed speed is workable because you rarely hold a contour for long. The 10-inch wheels handle roughness the engine lacks torque for.
Consider the deck material trade
The heavy-duty steel deck is durable and adds mass that helps traction, but that mass makes a mower harder to reposition when a wheel does lose grip.
Buying Guide: Choosing a Self-Propelled Mower for Hills
Drive type gets you most of the way. The rest covers the decisions that separate a good hill mower from a frustrating one.
Power source: torque against weight
Gas gives unlimited runtime and strong low-end pulling power, at the cost of weight, noise, exhaust and maintenance. Cordless gives instant start, quiet operation and a machine light enough to reposition, at the cost of capacity. The battery penalty on a hill is real: self-propelling uphill loads the motor continuously while the blade also works, so a mow that takes 40 minutes flat can use most of a charge on a steep section. Three workarounds help: buy a larger Ah pack, keep a second battery in rotation, and start at the bottom.
Rear wheel diameter, deck size and speed control
Wheel size is the most underrated hill spec. Models with 10-inch or 11-inch rear wheels roll over ruts and berms; models with 7-inch wheels drop into every depression, and each one becomes a small hill that stalls the drive. Deck size follows the same logic: a 20-inch deck is more nimble at the top of a slope, a 22-inch deck covers ground faster but wants more room to pivot. Match both to the shape of the hill rather than the size of the lawn. A single-speed drive is the second most common hill mistake after front-wheel drive, because you either outrun the mower on a descent or strain against it on a climb.
Why mowers bog down going uphill
Four causes account for nearly every case, in order of likelihood.
1. Front-wheel drive losing contact. Weight shifts rearward, the drive wheels unload, and the tires spin. This one is fixed by the purchase decision, not a technique.
2. Tall or wet grass. The blade load climbs faster than the drive can compensate. Mow dry grass, and never mow a damp slope.
3. A full grass bag. Added weight and a raised center of gravity make the mower less willing to hold a contour. Empty before the hill, not during it.
4. Wrong speed setting. Running the drive too fast uphill wastes traction. Slow it down and let the torque do the work.
Start at the bottom of every slope, drive down under your own power, and start there. Starting at the top means the engine or motor is loaded the instant it fires, which is when startups fail.
How to Mow a Steep Hill Safely
Technique matters as much as the machine on any grade steep enough to notice.
Mow side-to-side across the slope, not up and down it, so gravity works across the machine rather than straight down it.
Mow dry grass only. Wet clippings mat, clog, and add exactly the weight that removes your traction.
Set the deck one position higher than on the flat, since a low deck follows ruts and scalps.
Slow the self-propel to a careful walk and keep both hands on the handle.
Empty the bag before the hill rather than on it.
Wear footwear with a grippy, lugged sole rather than smooth shoes.
Turn by opening the drive and pivoting on the drive wheel, keeping the mower below you.
Know the bail-out. Releasing the handle stops the drive and kills the blade, so let go the instant the machine starts running downhill.
One boundary rule no product page will tell you: a walk-behind is the safer machine on a slope because you can step clear of it. That advantage disappears the moment the grade exceeds what the drive can hold.
When a Hill Is Too Steep to Mow
If a mower will not hold a contour in dry conditions with a bare deck, a full bagger and wet grass will not improve it. Here is the decision path.
1. Trim it from the bottom up. A brushcutter or string trimmer works a steep bank safely because you stand below the cut and swing upward. This is the standard answer for drainage ditches, berms, and the strip between a wall and a fence.
2. Upgrade to a machine with more stability. For sustained grades beyond a walk-behind, forum owners point consistently to articulated machines with a low center of gravity, and to zero-turn designs with steerable front wheels for maneuvering.
3. Consider a battery robotic mower. AWD robotic models are a genuinely different answer for very steep, large acreage, and owners report they handle slopes you could not comfortably walk behind with a mower at all.
4. Change the ground instead. On a persistent washout, re-grading with proper drainage and erosion control fixes the mowing problem permanently.
For a one-season problem, hire a service. A crew with commercial walk-behinds handles grades a homeowner machine will not.
If a walk-behind is the wrong shape of machine for your yard, our guide to the best riding mowers for hills and slopes covers that tier.
Frequently Asked Questions
Do self-propelled mowers work on hills?
Yes, provided the drive wheels are rear-wheel drive or all-wheel drive and you can vary the self-propel speed. On a grade the drive wheels must stay loaded with the mower’s weight to create traction. Front-wheel-drive mowers lose that contact going uphill, which is why they spin and bog on inclines.
What self-propelled mower is best for steep hills?
For a steep, sustained grade, choose rear-wheel drive with variable speed control and large rear wheels. If weight is the deciding factor, a light cordless machine with a high Ah battery is easiest to control. For a large or rough property, a gas model with a four-cycle engine and 10-inch or 11-inch rear wheels has more low-end torque and no runtime limit.
Why does my mower bog down when going uphill?
The most common causes are front-wheel drive losing wheel contact as weight shifts backward, tall or wet grass raising the blade load, a full grass bag adding weight high on the frame, and running the self-propel speed too fast for the grade. Slow the drive, mow dry grass only, empty the bag before the hill, and start at the bottom of the slope.
Is it okay to pull a self-propelled mower backwards?
You can back a self-propelled mower down a slope with the blade off, but never walk backward down a grade with the mower running and the blade engaged. Back down with the drive disengaged, then reposition side to side. If the machine starts sliding downhill, release the bail-out handle, which stops the drive and the blade, and step clear.
Should I mow a hill up and down or side to side?
Side to side, across the slope, for a walk-behind mower. Mowing up and down puts gravity directly against you and the machine, and a mower that loses traction becomes a heavy object heading downhill. Side-hilling lets you set a slow speed, keep the deck level, and stop the machine by releasing the handle instead of fighting it.
Conclusion: The Best Self Propelled Lawn Mowers for Hills
Drive type decides this purchase. Every mower we recommend for hills uses rear-wheel drive except the YARDMAX, and that is not an accident. Weight, wheel size and speed control then separate a good hill mower from a mediocre one.
The EGO POWER+ LM2135SP is our pick because 7.0 ft-lbs of torque, a 0.9 to 3.1 mph speed range, and a 55.3 pound build combine the control and the recovery margin a slope demands. The Greenworks 80V is the value answer if you want rear-wheel drive and load-sensing power for less. The PowerSmart 150cc covers the gas route with a reliable Briggs and Stratton engine and unlimited runtime.
If you cannot push a mower uphill at all, start with weight rather than power. The SKIL PWR CORE 40 is the lightest option here. If your hills are rough rather than steep, prioritize rear wheel diameter above everything else, and the SENIX with its 11-inch rear wheels is built for that yard.
Whichever you choose, mow it side to side, on dry grass, starting at the bottom. That habit protects you and the machine more than any specification on this list. For more options, see our roundup of the best self-propelled mowers overall.
