Yard work gets simpler when the mower matches the lot. This roundup focuses on gas self-propelled and a few closely related walk-behind picks for people who mow regular suburban grass, manage a sloped back yard, or want less push effort on thicker patches.
You’ll see the main differences quickly: deck size, engine size, drive style, and how each machine handles mulching, bagging, or side discharge. That mix matters more than flashy language, because the right setup can save time on every cut and feel far less tiring over a season.

More Details On Our Top Picks
That 22-inch deck gives you a wider cut than the 21-inch options lower in the list, so fewer passes make sense for a medium yard. The 170cc four-cycle engine and rear-wheel drive suit sloped sections or thicker spring growth without feeling overly fussy.
You also get three mowing paths, mulch, bag, or side discharge, which makes this a flexible fit for weekly upkeep and messier cleanup days. In most suburban lawns, the six height settings give enough room to match seasonal growth without turning the job into a project.
Strong Points
- Self-propelled rear-wheel drive reduces the push effort on longer cuts.
- 22-inch cutting width covers ground faster than the 18-inch pick below.
- Mulch, bag, and side-discharge modes cover different lawn conditions.
- Six cutting heights make seasonal adjustment straightforward.
- Four-cycle engine design fits regular yard routines well.
Things To Consider
- Rear-wheel drive helps, but tight corner work can still feel bulky.
- The larger deck may be less comfortable in narrow side yards.
- Gas upkeep means you’ll still manage fuel, oil, and routine cleaning.

Who It Suits Best
You’ll appreciate this most for a medium-size lawn with uneven spots, a few slopes, or weekly grass that never stays tiny for long.
A Better Fit Elsewhere
YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower works better for you when variable pace control matters more than rear-drive simplicity.
This one keeps the formula plain: a 21-inch deck, a 144cc OHV engine, and a push design for straightforward lawn care. The steel deck matters here because it usually feels like the sturdier choice for routine use, though it can add some heft compared with lighter decks.
For smaller yards or flatter spaces, that simpler setup can feel easier to live with than a self-propelled mower that you don’t really need. You still get the same three discharge paths as the first pick, so clippings management stays flexible without moving into a more complex machine.
What We Like
- 21-inch deck keeps it manageable in many suburban yards.
- Push operation gives you direct control in tight turns.
- Steel deck supports a more rugged feel for regular mowing.
- Mulch, bag, and side discharge cover common cleanup needs.
- Six height settings make seasonal changes simple.
Room For Improvement
- Push operation asks more from you on longer or thicker lawns.
- The steel deck may feel less nimble than a lighter build.
- It suits flatter ground better than steep, rolling terrain.
Core Details
Who Will Love This
You’ll get the most from this in a smaller or flatter yard where push control feels natural and self-propelled support would be more than you need.
Where A Sibling Pick Shines
PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower makes more sense for you if your lawn has slopes, thicker patches, or just feels tiring to push by hand.
The battery-and-charger bundle shifts this away from the gas-heavy feel of the first two picks, which can suit a smaller home lot or a quick weekend trim. A 16-inch deck is easier to steer around edging, flower beds, and tighter gate openings, though it asks for more passes across open turf.
That trade-off is pretty clear: less width and no gas engine upkeep, but also less brute force for thick, overgrown grass. For a compact lawn, the easier handling can matter more than raw cutting speed, and that’s where this Greenworks model earns its place.
Highlights
- 16-inch deck moves easily around tight landscaping.
- Battery setup skips gas mixing and fuel storage.
- Included charger makes the bundle more complete.
- Good fit for small lawns and light weekly trimming.
Softer Spots
- Smaller deck means more passes on bigger yards.
- Battery runtime can feel tighter on larger or thicker lawns.
- It lacks the sustained pulling feel of gas self-propelled models.

Built With In Mind
You’ll likely prefer this for a compact yard, close landscaping, or a lighter mowing routine where maneuverability matters most.
Swap It Out When
PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower suits you better when your lawn is larger, thicker, or hilly enough to reward self-propelled help.
This AMERISUN keeps the useful basics together: self-propelled movement, a 170cc OHV engine, and a 21-inch cut. The 1.4-bushel catcher is worth noting for people who prefer bagging clippings and don’t want to empty a tiny bin every few minutes.
Compared with the PowerSmart 21-inch push model, this one gives you more help across longer yards and a more hands-off feel on routine mowing days. The six-position height setup also keeps adjustment simple, which is useful when your grass doesn’t stay the same length for long.
Reasons To Buy
- Self-propelled drive lowers the effort on broader lawns.
- 1.4-bushel catcher supports cleaner bagging sessions.
- Three mowing modes cover mulching, side discharge, and collection.
- Six cutting heights make seasonal trimming easy to tune.
- 21-inch deck stays manageable for many home lawns.
Small Caveats
- Bagging setup adds emptying and cleanup work.
- The catcher size may still feel modest on heavy clipping days.
- Gas upkeep is part of the ownership routine.

Who Should Grab It
You’ll like this most for a standard home lawn where self-propelled help and a bagging option both matter.
Look Elsewhere When
YARDMAX 22 in. 201cc Select PACE 6 Speed CVT High Wheel FWD 3-in-1 Gas Walk Behind Self Propelled Lawn Mower fits you better when pace control and hill handling matter more than a simple 21-inch setup.
The rear-discharge setup makes this one stand apart from the earlier PowerSmart model with side discharge, and that difference matters on longer, coarser grass. A 22-inch deck and 170cc four-cycle OHV engine keep it in the same broad-yard category, so it still suits regular mowing rather than just occasional touch-ups.
For yards that throw a lot of clipping volume, rear discharge can feel more natural than bagging every time. You may find this especially handy in spring growth, where the mower has to move through more material without much drama.
Upsides
- Rear-discharge setup helps move clippings fast.
- 22-inch deck handles broader spaces efficiently.
- Self-propelled design reduces the physical push.
- Three-way mowing setup adds practical flexibility.
- Six cutting heights support routine lawn adjustments.
Points To Note
- Rear discharge can leave a looser finish than bagging.
- Large cutting width can feel bulky around garden edges.
- Gas engine care still stays in the routine.
Technical Sheet
Who It Suits Best
You’ll get the most from this on a larger lawn where rear discharge feels more useful than a spotless bagging finish.
Reach For A Different Pick When
AMERISUN 21 Self-Propelled Gas Lawn Mower fits you better if you want a smaller deck and a built-in catcher for neater cleanup.
This version keeps the PowerSmart formula compact enough for average yards, but still adds self-propelled rear-wheel drive and a steel deck. That mix usually works well for people who want a sturdy-feeling mower without stepping up to the wider 22-inch frame from the first model.
The 3-in-1 mowing setup gives you the same familiar flexibility as the others, so you can shift between mulching, bagging, or discharge without changing machines. For weekly mowing, that kind of simple predictability is often worth more than extra bells and whistles.
Best Bits
- 21-inch deck stays easier to guide than larger models.
- Rear-wheel drive helps with traction and pace control.
- Steel deck adds a solid, durable feel for regular use.
- Three cutting modes cover common yard cleanups.
- Self-propelled assist helps on mild slopes.
Worth Noting
- Steel deck weight can make storage and turning less nimble.
- It doesn’t have the extra width of the 22-inch options.
- Gas maintenance stays part of your routine.
Feature Rundown
Right Fit For
You’ll appreciate this for regular suburban mowing where dependable handling matters more than big-deck speed.
Another Choice May Suit
PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower fits you better if your yard is larger and you want a wider cut.
The 18-inch deck makes this the smallest gas option here, and that shape works in narrow side yards, around shrubs, or through tighter gate openings. A 144cc four-stroke OHV engine and side discharge keep the build straightforward, which is useful for light trimming and quick weekly runs.
Compared with the bigger PowerSmart mowers, this one asks for a bit more patience on broad lawns, but it gives back easier steering. For a smaller property, that trade can feel right from the first pass, especially where every turn needs to be clean and simple.
Positives
- 18-inch width is easy to manage in tight spaces.
- Side discharge moves cut grass out quickly.
- Five height positions add basic trimming flexibility.
- Smaller frame suits compact storage and lighter handling.
Areas To Watch
- Smaller deck means more passes across open turf.
- Side discharge leaves a less tidy finish than bagging.
- It suits small yards better than broad, demanding lawns.

Where A Sibling Pick Shines
PowerSmart EasyGlide 21-Inch Gas Lawn Mower fits you better if you want a wider deck and a bit more versatility from the same brand family.
YARDMAX brings the most control-focused setup in this group, with a six-speed CVT, or continuously variable transmission, that lets you fine-tune pace instead of settling for a single pull rate. The 22-inch deck, 201cc engine, and high-wheel front-drive layout point toward bigger lawns and ground that changes underfoot.
That extra flexibility helps on slopes, bumps, and yards where your walking speed changes from one section to the next. Compared with the simpler PowerSmart options, this one feels more tailored to terrain and pacing, though the more advanced setup can be more than some small yards need.
Bright Spots
- Six-speed CVT gives you a wider pace range.
- High wheels help over rougher ground.
- Front-wheel drive supports directional control on mixed terrain.
- 22-inch width covers a lot of lawn per pass.
- Three-in-one mowing keeps cleanup choices flexible.
Honest Caveats
- More drivetrain complexity can feel like extra mower to learn.
- It may be more machine than a tiny yard needs.
- Hazard-material shipping rules can affect how this item is handled.

Whose Shelf It Belongs On
You’ll get the most from this on a larger, uneven yard where pace control matters as much as cutting width.

PowerSmart 21-Inch Self Propelled Gas Lawn Mower makes more sense for you if you want a simpler setup for a standard-size lawn.
How To Choose The Right Gas Self-Propelled Lawn Mowers
Match Deck Size To Your Yard
Deck width shapes how fast you finish the job. A 22-inch mower covers more ground than an 18-inch model, while a 21-inch deck usually lands in the middle for control and speed.
Smaller yards and tighter side passages favor compact decks, because they turn more easily around landscaping and narrow gates. Larger open lawns reward wider decks, since fewer passes mean less time spent walking back and forth.
Choose Drive Style With Your Terrain In Mind
Rear-wheel drive often feels steadier on slopes and thicker grass, because the powered wheels sit where traction matters most. Front-wheel drive can feel easier to guide around turns and over flatter ground.
Some models add pace control or speed settings, and that can be useful for uneven yards where your walking speed changes often. Simple self-propelled systems suit casual lawn care, while more adjustable drives fit longer sessions and mixed terrain.
Think Through Engine Size And Grass Load
Engine size gives you a rough sense of how much grass the mower can move without feeling strained. A 144cc engine fits lighter, routine cuts, while 170cc and 201cc options lean better toward thicker growth and larger properties.
The honest read is that power only helps when the rest of the setup supports it. A strong engine with a small deck still takes time on broad lawns, while a lighter engine can feel fine on a tidy, regularly cut yard.
Pick The Clipping Path You’ll Use Most
Mulching returns chopped clippings to the lawn, bagging gathers them for a cleaner finish, and side discharge or rear discharge moves grass out quickly. Each path solves a different yard problem, so the best pick is the one that fits your cleanup habits.
Bagging feels neat but adds emptying work, while discharge modes are easier on thick growth yet look less polished right after mowing. Mulching is often the middle ground for weekly upkeep, especially on grass that stays at a manageable height.
Things Worth Knowing First
Common Shopping Slip Ups
Shoppers often focus on engine size and miss deck width, drive layout, and terrain. That usually leads to a mower that sounds strong on paper but feels awkward in your actual yard.
Another common miss is choosing too much machine for a small lawn. A wide, heavy mower can make storage, turning, and edging more annoying than helpful.
The Case For Spending Up
Higher-tier gas self-propelled mowers usually cost more because of stronger engines, broader decks, more control in the drive system, or sturdier frame parts. You also tend to see better traction features and more useful cut options as the price band rises.
Paying up makes sense when your yard is large, sloped, or thick with seasonal growth. For a small, level lawn, a simpler mower often covers the basics without extra complexity.
Frequently Asked Questions
What Size Lawn Fits A 22-Inch Mower Best?
A 22-inch mower fits medium and larger yards well, because it cuts a wider path each pass. It can still work on smaller lawns, but narrow spaces may feel less convenient.
Is Rear-Wheel Drive Better Than Front-Wheel Drive?
Rear-wheel drive usually feels more helpful on slopes and thicker grass. Front-wheel drive often feels easier to steer in flatter yards and around tighter corners.
Do You Need A Self-Propelled Mower For A Flat Yard?
You may not need it for a small, flat lawn, especially if you mow often. Push models can be perfectly practical when the yard stays light and manageable.
What Does 3-In-1 Mowing Mean?
It means the mower can mulch, bag, and discharge grass. That gives you more control over how clippings look and where they go.
Which Engine Size Feels Right For Regular Home Use?
For lighter lawns, 144cc can be enough. For thicker grass or bigger spaces, 170cc or 201cc gives you more breathing room.
Closing Thoughts
Your best match depends on yard size, slope, and how much cleanup you want after each mow. The PowerSmart 22-inch self-propelled options give you a strong middle ground, while the YARDMAX suits more demanding terrain and the 18-inch PowerSmart keeps things compact. For small yards, the Greenworks battery model is easier to manage, and for a standard gas setup, the 21-inch picks stay sensible. Choose the machine that fits your lawn first, and the mowing routine gets a lot less tiring.
