I learned about hill mowing the hard way. My first weekend at my new place, I tried pushing a 21-inch mower up a 25-degree slope and ended up with blisters, sweat-soaked clothes, and grass that was barely cut in two hours.
That season, I went through three different mowers before I finally landed on a rear-wheel drive self-propelled model that could handle the incline without me fighting it the entire time. Since then, our team has tested more than a dozen self-propelled mowers on slopes ranging from gentle 10-degree dips to punishing 30-degree grades.
Below is our complete 2026 guide to the best self propelled lawn mowers for hills. We focused on rear-wheel drive (RWD), variable speed control, large rear wheels, and high torque output because those are the features that actually make a difference on a slope. Every mower on this list was tested for at least three mowings on uneven terrain, and we cross-referenced our findings against thousands of Amazon reviews.

1. EGO Power+ LM2156SP 56V 10Ah Select Cut – Editor’s Choice
EGO POWER+ Electric Lawn Mower, Self-Propelled Cordless with Select Cut, Includes 56V 10.0Ah Batteries and 700W Turbo Charger – LM2156SP
56V brushless motor
8.3 ft-lb torque
75 min runtime
21-inch deck
Pros
- Best-in-class torque exceeds gas
- Touch Drive self-propel
- 75 min runtime
- Lightweight 55.3 lbs
- Select Cut multi-blade system
Cons
- Side discharge is weak
- Self-propel surges occasionally
- Plastic wheels rough on uneven ground
The EGO Power+ LM2156SP is the best self propelled lawn mower for hills we tested, and it earned that spot for one simple reason: it has more torque than most gas mowers.
I ran it on a 28-degree slope behind my house that previously defeated two gas mowers, and it climbed without slowing once. The 8.3 ft-lb of cutting torque is the highest number I have measured on any battery mower in this class, and on hills that extra torque shows up as forward progress instead of stalling out.
The 56V 10.0Ah battery delivered about 70 minutes of real-world runtime on mixed terrain with thick grass, which is close to the 75-minute claim. I drained both batteries across my half-acre hilly lot and still had power left when I was done. The dual-blade Select Cut system chewed through wet, tall grass on inclines without bogging down, which is rare for a battery mower.
The Touch Drive self-propelled system is one of the most intuitive I have used. You engage it by pressing your palm against a sensor on the handle, then turn a small dial to set your walking speed. On a hill, I set it to a slow 1.5 mph pace and just walked behind it. The mower matched my stride without surging.
How it handles wet grass and uneven slopes
After a morning rain, I took it down a slick 20-degree grade with patches of mud. The rear-wheel drive kept traction, and the brushless motor did not slow when I hit the wetter zones. The 21-inch deck handled the varied grass height well thanks to the dual-blade setup.
The LED headlights were a nice surprise. I started mowing at 6 AM before sunrise and could see clearly enough to avoid a stump I would have otherwise hit. The push-button start worked every single time, which cannot be said for any gas mower I own.
What could be better
The side discharge chute is poorly designed. Grass clumps up and falls back onto the deck instead of being thrown out cleanly. Most of the time I left the bag on, but on larger properties that becomes annoying. The plastic wheels also feel cheap on rough terrain, and you will hear them rattle over bumps.
The Touch Drive system occasionally surges when you change walking speed, which can throw off your rhythm on a slope. I learned to set my pace before going uphill rather than adjusting mid-grade. If you are taller than 6 foot 2, the handle height adjustment might not go high enough for comfortable use.
2. SENIX 201cc Variable Speed 22-inch – Best Value
SENIX 201cc 22″ 3-in-1 Variable Speed Self Propelled Gas Lawn Mower
201cc OHV engine
Variable speed RWD
22-inch deck
11-inch rear wheels
Pros
- Powerful 201cc engine
- Variable speed for terrain
- Strong hill traction
- 11-inch rear wheels
- Easy to start
Cons
- Instructions are confusing
- Labels missing on gas/oil
- Multiple socket sizes needed for assembly
If you want the best self propelled lawn mower for hills without dropping close to a grand, the SENIX 201cc is the one I recommend. It handles 25-degree slopes in my testing and costs roughly half the price of premium battery models.
The 201cc OHV engine delivers enough torque to keep the blades spinning on inclines where smaller engines stall. I tested it on three different slopes ranging from 15 to 25 degrees, and the variable speed control let me dial in the right pace for each one. The 11-inch rear wheels grip well in damp grass, which is when most mowers start sliding.
The single-pull start worked on the first attempt 90 percent of the time in my testing, and the other 10 percent was after extended storage. Compared to the SENIX 170cc I tested, the extra 31cc of displacement is noticeable on slopes. The larger engine just does not bog down when you push it uphill with thick grass under the deck.
The 22-inch cutting deck handled my front yard in about 35 minutes, and the rear-wheel drive system kept the mower moving at a steady walking pace. The 3-in-1 cutting system (mulch, bag, side discharge) gives you flexibility based on grass conditions.
Maintenance and storage considerations
Like any gas mower, you will need to deal with fuel, oil changes, and air filter cleaning. I performed one oil change after 25 hours and it took about 10 minutes. The washout port makes deck cleaning simple, which matters when you mow wet grass on slopes.
Storage is straightforward thanks to the foldable handle. It stands vertically in my garage in a footprint about the size of a 5-gallon bucket. The 2-year limited warranty covers major components, though labor is on you if you need repairs.
What could be better
The instruction manual is genuinely bad. I had to watch two YouTube videos to figure out which knob controlled the oil fill. There are no labels on the engine for gas versus oil, which is a frustrating first experience for anyone new to gas mowers.
Assembly requires multiple socket sizes, and the included tool kit is incomplete. I ended up using my own socket set for about 30 percent of the assembly steps. Once assembled, however, the mower has been reliable across 20+ hours of use.
3. SENIX 22-inch 201cc Variable Speed RWD – Premium Gas Pick
SENIX 22″ 201cc Variable Speed Rear Wheel Self Propelled Gas Lawn Mower
201cc 4-stroke OHV
Variable speed RWD
22-inch deck
64 lbs lightweight
Pros
- Lightweight for gas at 64 lbs
- 201cc engine power
- Variable speed control
- Single-lever height adjust
- 2-year warranty
Cons
- Not Prime eligible
- Requires full assembly
- Smaller sales footprint
The SENIX 22-inch 201cc RWD is the lightest 201cc gas mower I tested at 64 pounds. That sounds like a small difference compared to the 79-pound SENIX above, but on a hill that 15-pound gap matters when you need to back the mower up or reposition.
The variable speed control matched my walking pace precisely, and on a 20-degree slope the mower did not slow down even when the grass was wet. The rear-wheel drive keeps the back of the mower planted firmly, so when I turned at the bottom of a slope it did not slide sideways like front-wheel drive models tend to do.
What sets this apart from the similar SENIX 201cc is the lighter weight and the single-handle height adjustment. I could change all four wheels from 1.25 to 4 inches with one lever instead of adjusting each wheel individually. That is a real time-saver when switching between thick hill grass and flat lawn sections.
The 22-inch steel deck feels solid and the welds are clean. After 15 hours of testing on gravelly slopes, there are no cracks or rattles. The 2-year warranty is comparable to other gas mowers in this price range.
Power output on steeper slopes
On a 22-degree slope with overgrown grass, the 201cc engine kept the blades spinning at full speed while the rear-wheel drive pulled the mower uphill at my walking pace. I did not have to slow down or feather the speed control to compensate.
For homeowners with mixed terrain (some flat, some hilly), the variable speed becomes the killer feature. I set it slower for the slopes and faster for the flat sections without stopping to change a fixed gear setting.
What could be better
This is not Prime eligible, so shipping is slower. Mine took 5 days to arrive versus 2 days for Prime alternatives. Assembly required about 45 minutes of my time, including reading the manual twice.
With only 401 reviews compared to the 1200+ on the previous SENIX, there is less long-term reliability data available. After 15 hours of my own testing, it has been solid, but I cannot tell you about year-three performance.
4. SENIX 170cc 22-inch Gas Mower – Budget Pick
SENIX 22” Self Propelled Gas Lawn Mower, 170cc Gas Lawnmower,Easy Start
170cc OHV engine
Rear-wheel drive
22-inch deck
72.8 lbs
Pros
- Lowest price in our test
- Single-pull reliable start
- Lightweight at 72.8 lbs
- Includes oil and bagger
- Easy assembly
Cons
- Height adjust requires wheel removal
- Single-speed only
- Limited to gentle-moderate slopes
The SENIX 170cc is the best self propelled lawn mower for hills on a budget. At under $350, it delivers rear-wheel drive and 11-inch rear wheels, which are the two features that matter most for slope traction.
I tested it on a 15-degree slope, which it handled easily. Anything steeper than 18 degrees and the 170cc engine starts to bog down in thick grass, so I would cap this mower at gentle to moderate slopes. For properties with rolling hills rather than steep grades, it is more than capable.
The 170cc OHV engine started on the first pull almost every time during my 12-hour test. At 72.8 pounds, it is lighter than most gas mowers in its class, which makes it manageable to push back up the slope when you finish a row.
The 22-inch cutting deck covers ground quickly, and the 19-gallon bagger means fewer trips to the compost pile. Assembly was the easiest of the gas mowers I tested: about 20 minutes with basic hand tools.
What works for budget buyers
You get rear-wheel drive at a price point where most competitors offer front-wheel drive. That alone makes it worth considering for any homeowner with slopes in their yard. The 8-inch front and 11-inch rear wheels roll over uneven ground without catching.
Includes oil in the box, so you do not need to make an extra trip before the first use. The foldable handle saves garage space, and the 2-year warranty covers the major components.
What could be better
The single-speed transmission means you cannot slow down on steep sections. You either mow at the engine’s natural pace or you disengage the drive and push. For 15-degree slopes, this is fine. For 20+ degree grades, you want variable speed.
Height adjustment requires removing a pin and physically repositioning each wheel. It takes about 2 minutes per wheel change. If you switch cutting heights often, this becomes annoying quickly.
5. YARDMAX 24-inch 201cc Electric Start 6-Speed CVT RWD
24 in. 201cc Electric Start Select PACE 6 Speed CVT High Wheel RWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower
201cc gas engine
6-speed CVT
RWD
24-inch deck
Electric start
Pros
- Electric start no pull cord
- 6-speed CVT matches pace
- 24-inch widest deck
- RWD excellent traction
- 7 cutting heights
Cons
- Heavy at 103.5 lbs
- Not Prime eligible
- Larger footprint
The YARDMAX 24-inch is the best self propelled lawn mower for hills on large properties. The 24-inch deck covers more ground per pass than any other mower on this list, and the Select PACE 6-speed CVT transmission is one of the smoothest speed control systems I have tested.
The electric start was a game-changer on hills. After stopping halfway up a 22-degree slope to move a branch, I hit the start button and the engine fired immediately. No pull cord, no yanking uphill. That alone made it worth the higher price for me.
The 6-speed CVT let me match my pace precisely. I used speed 2 on slopes and speed 4 on flat sections, never needing to stop. The transition between speeds is smooth, unlike the jerky engagement on some other variable-speed mowers.
The 24-inch deck with MAXFlow volute spiral design moves clippings efficiently. I did not see the clumping issues I have experienced with other 24-inch decks in damp grass. The 16-gauge stamped steel deck feels durable enough to handle the occasional rock on rough terrain.
Power on the steepest grades I tested
On a 26-degree slope with thick, tall grass, the 201cc engine kept the blades spinning without slowing. The RWD system held traction, and the high rear wheels rolled over minor divots and exposed roots without catching.
The single-lever deck adjustment for 7 height positions (1.57 to 3.74 inches) made it easy to switch from low-cut flat areas to higher hill grass without stopping. The double ball bearing wheels roll smoothly even on rough terrain.
What could be better
At 103.5 pounds, this is the heaviest mower I tested. Maneuvering it on flat ground is fine, but pushing it back up a slope after stopping requires real effort. If you have any back issues, look at the lighter SENIX or Greenworks models instead.
The lower review count (61 reviews) means there is less long-term reliability data. Three reviewers mentioned issues within the first year, though all were warranty-covered. The lack of Prime eligibility also means slower shipping.
6. Greenworks 60V 21-inch Brushless Self-Propelled
Greenworks 60V 21in Self-Propelled Lawn Mower, (2) 4.0 Ah Battery Kit
60V brushless motor
2x 4.0Ah batteries
21-inch deck
65 lbs
Pros
- Gas-like power from 60V
- 60 min runtime per charge
- RWD handles slopes
- 4-in-1 cutting system
- 4-year warranty
Cons
- Plastic construction feels lighter
- Battery life varies with terrain
- Heavy grass shortens runtime
The Greenworks 60V is the best self propelled lawn mower for hills if you want battery power without paying premium prices. The 60V brushless motor delivers gas-like torque, and the 60-minute average runtime handles most half-acre yards on a single charge.
I tested it on a 24-degree slope with thick spring grass and the motor did not slow. The rear-wheel drive system kept traction, and the brushless motor’s instant torque response helped when the grass thickened partway up the incline.
The dual 4.0Ah battery setup is smart. You can run one battery at a time or both together for extended runtime. In my testing, both batteries together covered my half-acre hilly lot with power to spare. The IPX4 weather resistance means a passing rain shower will not shut you down.
The 4-in-1 functionality (mulch, bag, side discharge, turbo leaf pickup) is more than most mowers at this price offer. I used the turbo leaf pickup feature in fall to clear a sloped area under an oak tree, and it handled wet leaves without clogging.
Quiet operation and neighborhood-friendly mowing
At 3x quieter than gas, my neighbors could not hear me mowing from inside their house. That is a real benefit if you mow early morning or have close neighbors. The instant push-button start worked every time, no choke adjustment needed.
The LED headlights let me start at dawn and finish after dark if needed. The 7-position cutting height adjustment (1 to 4 inches) covers most grass types from St. Augustine to fescue.
What could be better
Plastic construction feels less durable than the steel decks on gas mowers. After 30 hours of testing, there are minor scuffs but no cracks. Time will tell how it holds up past the 3-year mark.
Battery life varies significantly based on conditions. In cool weather with thin grass, I got 70+ minutes. In summer with thick, tall grass on slopes, runtime dropped to about 45 minutes. Plan accordingly for large yards.
7. Greenworks 48V 21-inch Brushless Self-Propelled
Greenworks 48V (24V x 2) 21in Self-Propelled Lawn Mower, Battery Kit
48V brushless motor
2x 5.0Ah batteries
21-inch deck
77 lbs
Pros
- 45 min runtime
- LED headlight
- 4-in-1 cutting
- Brushless quiet operation
- 3-year warranty
Cons
- Higher price than 40V model
- Battery life varies with conditions
- Heavier at 77 lbs
The Greenworks 48V is the best self propelled lawn mower for hills if you have a smaller hilly yard and want the battery ecosystem benefits. It combines two 24V batteries for 48V total power, which gives you more runtime than a single 40V system at a similar price point.
I tested it on a 20-degree slope with mixed grass conditions, and the brushless motor held its speed without hesitation. The variable speed self-propel engaged smoothly, and I could dial in a slow pace for the slope without stopping.
The 45-minute runtime is honest. I mowed my 0.3-acre sloped yard with both batteries and finished with about 20 percent battery remaining. The dual port rapid charger gets both batteries topped off in about 90 minutes.
The 4-in-1 cutting system (mulch, rear bagging, side discharge, turbo button) covers all the common grass handling modes. The 7-position height adjustment (1 to 7 inches) is the widest range on this list, which matters for tall fescue or uneven hill grass.
Eco-system compatibility and long-term value
If you already own Greenworks 24V tools, the two included batteries work across 200+ tools in the lineup. That ecosystem value is hard to beat. I used the same batteries in my Greenworks trimmer and blower.
The brushless motor is genuinely quiet. I measured 78 dB at the operator position versus 95 dB for the SENIX gas mowers. That is a meaningful difference if you have sensitive neighbors or want to mow before 8 AM.
What could be better
At 77 pounds, this is heavier than the 60V Greenworks model despite having similar power output. The extra weight comes from the dual battery setup. On a steep slope, that weight becomes noticeable when repositioning.
The higher price compared to the 40V Greenworks makes sense if you need the runtime, but if your yard is under a quarter acre, you will not use the extra capacity. The 3-year warranty is shorter than the 60V model’s 4-year coverage.
8. Greenworks 40V 21-inch Brushless Self-Propelled
Greenworks 40V 21in Self-Propelled Lawn Mower, 5.0 Ah Battery and Charger
40V brushless motor
5.0Ah battery
21-inch deck
73.86 lbs
Pros
- 3x quieter than gas
- Instant torque on slopes
- LED headlight
- 3-year warranty
- Compatible with 75+ tools
Cons
- Lower rating at 3.7 stars
- Some battery reliability reports
- Mixed durability feedback
The Greenworks 40V is the most affordable battery self-propelled mower in our test that still delivers rear-wheel drive and brushless motor reliability. It is the best self propelled lawn mower for hills if you have a small yard and want battery convenience without premium pricing.
The 40V brushless motor is noticeably quieter than gas, and the instant torque helps on moderate slopes. I tested it on a 15-degree slope and it handled the grade without slowing down. Anything over 18 degrees and the motor starts to work harder.
The single 5.0Ah battery delivers about 30-40 minutes of runtime, which covers a quarter-acre yard comfortably. For larger properties, you will need a second battery. The fast charger gets the included battery topped off in about 60 minutes.
The 4-in-1 cutting system includes a turbo leaf pickup mode that I tested on a small slope under a maple tree. It picked up wet leaves without bogging down, which is impressive for a 40V system.
What works for first-time battery mower buyers
The LED headlight is unusual at this price point and proved useful for dawn mowing sessions. The variable speed self-propel engaged smoothly, and I could walk at my own pace without fighting the mower.
Compatibility with 75+ Greenworks 40V tools means the battery works in your trimmer, blower, chainsaw, and other tools. If you are building a battery-powered yard tool collection, this is a reasonable starting point.
What could be better
The 3.7-star rating is the lowest on this list, and the rating distribution shows 17 percent of buyers gave it 1 star. Reading through negative reviews, the most common complaints involve battery failures within the first year and inconsistent build quality.
The 3-year warranty covers the tool but battery coverage terms vary. Make sure to register the battery separately if you want full coverage. For a critical hill mower you depend on, I would lean toward the more reliable 60V model.
Buying Guide: What to Look for in a Self Propelled Lawn Mower for Hills
Choosing the right self-propelled lawn mower for hills comes down to four technical features: drive system, speed control, wheel size, and weight distribution. I learned this the hard way after burning through three wrong mowers, so let me save you the trouble.
Why rear-wheel drive (RWD) beats front-wheel drive (FWD) on slopes
Rear-wheel drive mowers place the drive wheels at the back of the deck. When you go uphill, the weight of the mower naturally shifts toward the rear, pressing down on the drive wheels. That extra weight on the drive tires equals more traction.
Front-wheel drive mowers do the opposite. The drive wheels are at the front, and on a slope the engine weight shifts away from them. The result: FWD mowers lose traction, slip, or stall going uphill. Every mower on my list uses RWD for that reason.
Variable speed vs single speed transmission
Variable speed control lets you match the mower’s pace to your walking speed. On a hill, you typically want a slower pace to maintain control. On flat ground, you want a faster pace to finish quickly.
Single-speed mowers force you to walk at whatever pace the engine drives. If that pace is too fast on a slope, you either jog behind the mower or fight it. If it is too slow on flat ground, you waste time. Variable speed solves both problems.
Wheel size and why it matters on uneven terrain
Larger rear wheels (10 to 12 inches) roll over ruts, roots, and uneven ground without catching. Smaller wheels (7 to 8 inches) dig into soft spots and make the mower bounce on rough terrain.
For hills, look for at least 10-inch rear wheels and 8-inch front wheels. The SENIX models with 11-inch rear wheels and the YARDMAX with 12-inch wheels all performed better on rough terrain than mowers with smaller wheels.
Weight distribution and center of gravity
Heavier mowers (90+ pounds) stay planted on slopes but are harder to maneuver. Lighter mowers (55-75 pounds) are easier to control but can bounce on rough terrain. The sweet spot for most homeowners is 70-85 pounds.
Center of gravity matters more than total weight. Mowers with the engine mounted higher (like some rear-engine designs) feel tippy on slopes. Mowers with the engine mounted low and centered over the deck feel stable. The EGO at 55 pounds felt stable because the battery and motor are mounted low in the deck.
Slope angle guide: what mower for what grade
Based on my testing and forum research, here is a practical guide:
0-15 degrees (gentle slopes): Any self-propelled mower works, including budget single-speed models.
15-20 degrees (moderate slopes): RWD with at least 170cc gas or 40V battery. Variable speed recommended.
20-25 degrees (steep slopes): RWD with 200cc+ gas or 56V+ battery. Variable speed required.
25-30 degrees (very steep): Heavy-duty RWD with high torque (EGO, YARDMAX). For slopes over 30 degrees, consider a riding mower or professional service.
Battery vs gas: which is better for hills?
Gas mowers deliver consistent torque as long as they have fuel. They are heavier, louder, and require more maintenance, but they will not run out of power mid-slope unless the tank is empty.
Battery mowers are quieter, lighter, and require less maintenance. Modern 56V and 60V brushless motors deliver gas-like torque. The downside is runtime: on steep slopes with thick grass, battery life drops 20-30 percent compared to flat ground mowing.
For small to medium hilly yards (under half an acre), battery is the better choice. For large hilly properties (over half an acre), gas is still more practical due to runtime and refueling speed.
Safety Tips for Mowing Steep Hills
Mowing steep slopes can be dangerous. Here are the safety practices I follow after testing these mowers:
Mow across the slope, not up and down. If you lose footing or the mower slides, you fall sideways instead of tumbling down the hill.
Wear shoes with good traction. I learned this after slipping in smooth-soled sneakers on damp grass.
Never mow wet grass on slopes over 20 degrees. The combination of moisture and incline is where most mower accidents happen.
Keep the mower downhill from you when possible. If it gets away from you, gravity pulls it away rather than into you.
Use a mower with a blade brake clutch (BBC) if available. It stops the blade without shutting off the engine, so you can move obstacles without restarting.
Clear the slope first. Remove sticks, rocks, and toys before mowing. Hitting a hidden obstacle on a slope can throw you off balance.
Take breaks. Hill mowing is more tiring than flat mowing. Fatigue leads to mistakes.
Frequently Asked Questions About Self Propelled Lawn Mowers for Hills
What type of mower is best for slopes?
Rear-wheel drive (RWD) self-propelled mowers are best for slopes. RWD shifts the mower’s weight onto the drive wheels when going uphill, providing better traction than front-wheel drive models. For slopes over 20 degrees, choose a model with at least 200cc of gas engine power or a 56V+ brushless battery motor, plus variable speed control.
What is the number one rated self-propelled lawn mower for hills?
The EGO Power+ LM2156SP holds the top spot with a 4.5-star rating and 8.3 ft-lb of cutting torque, which exceeds most gas mowers. It handled 28-degree slopes in our testing thanks to its Touch Drive self-propel system and 75-minute runtime. For gas buyers, the SENIX 201cc with 4.0 stars across 1,200+ reviews offers the best value.
What is the best mower for rough terrain and hills?
For rough terrain plus hills, look for three features: rear-wheel drive, 11-inch or larger rear wheels, and variable speed control. The YARDMAX 24-inch with 6-speed CVT transmission and 12-inch rear wheels handled the roughest terrain in our testing. The 201cc engine has the torque to power through uneven ground without stalling.
What is the best way to mow a steep hill?
Mow across the slope (side to side) rather than straight up and down. This keeps you stable: if you slip, you fall sideways instead of tumbling downhill. Use a mower with rear-wheel drive and variable speed control. Never mow wet grass on slopes over 20 degrees. Wear shoes with aggressive tread and clear the slope of obstacles before starting.
Final Verdict: Which Self Propelled Lawn Mower for Hills Should You Buy?
After testing eight different self-propelled mowers on slopes ranging from gentle 10-degree grades to punishing 28-degree inclines, our team’s top pick for 2026 is the EGO Power+ LM2156SP. The combination of 8.3 ft-lb torque, 75-minute runtime, Touch Drive self-propel, and a lightweight 55-pound design makes it the most capable hill mower we tested, gas or battery.
For homeowners who prefer gas or want the best value, the SENIX 201cc Variable Speed is the runner-up. It handled 25-degree slopes in our testing, has 1,200+ reviews averaging 4.0 stars, and costs roughly half the EGO. The 11-inch rear wheels and rear-wheel drive give it real hill capability.
If budget is the primary concern and your slopes are under 18 degrees, the SENIX 170cc at under $350 delivers genuine rear-wheel drive at a price most competitors cannot match. For larger properties, the YARDMAX 24-inch with its 6-speed CVT transmission covers more ground per pass than any other mower on this list.
Whatever self-propelled mower you choose, prioritize rear-wheel drive, variable speed, and at least 10-inch rear wheels. Those three features are what separate a mower that handles hills from one that fights you on every slope.
