More Details On Our Top Picks
A 22-inch deck gives you a wider path than the smaller push models in this list, and the rear-wheel-drive setup helps the mower keep traction on uneven ground. That combination suits a yard with slopes, thick patches, or long edges where a little extra drive assistance matters.
The 170cc four-cycle engine keeps the setup straightforward, while the 3-in-1 cutting setup lets you mulch, bag, or side-discharge depending on the season. You may find it especially useful for a standard suburban lot where one machine has to handle spring growth, summer trimming, and occasional cleanup.
Strong Points
- Rear-wheel drive helps on climbs and rough patches.
- 22-inch cutting width trims more grass per pass, which matters on larger lawns.
- Three cutting modes let you match the finish to the job.
- Six height settings make seasonal changes easier to manage.
Things To Consider
- The larger deck takes a bit more space in storage.
- Rear-drive mowing tends to feel less nimble in tight corners than a compact push model.
- Regular blade cleaning helps keep discharge smooth after damp mowing sessions.

Who It Suits Best
You get the most from this model on a medium-size lawn with slopes, patches of thick growth, or mixed mowing conditions.
Where A Sibling Pick Shines
PowerSmart EasyCut 18-Inch Gas Lawn Mower fits better for a smaller, easier-to-store yard where a lighter push machine makes more sense.
This one strips the setup back to a push walk-behind format, which suits smaller lawns and flatter yards where you do not need drive assistance. The steel deck gives it a sturdier feel than many lightweight shells, and the 21-inch width stays manageable around fences, beds, and narrow gates.
The 144cc four-stroke OHV engine is the sort of specification that makes sense for routine grass cutting without making the mower feel oversized. Compared with the rear-drive PowerSmart model above, this version asks more from you physically, but it also keeps the machine simpler and often easier to park in a tight shed.
What We Like
- Push design keeps the mower straightforward and familiar.
- Steel deck adds a more durable feel for regular use.
- Three cutting modes cover mulch, bagging, and side discharge.
- Six height settings help you adapt to changing grass length.
Room For Improvement
- Manual pushing can feel tiring on larger yards.
- The narrower deck than the 22-inch options means more passes on wide lawns.
- Steel decks benefit from routine cleaning after wet clippings.
Technical Sheet
Right Fit For
You suit this mower best when your lawn is modest in size and you want a plain, dependable push format.
Swap It Out When
PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower makes more sense for hilly yards or anyone who wants drive assistance.
The 1.4-bushel grass catcher makes this AMERISUN model feel more tailored to cleanup-minded mowing, especially for yards that drop a lot of clippings after spring growth. Unlike the simpler PowerSmart push model, this one adds self-propelled drive and a more complete bagging setup, so the workload shifts away from your legs a bit.
The 170cc OHV engine and six cutting positions give you enough range for routine yard care without drifting into overbuilt territory. The honest read is that it looks best for homeowners who want mulching, side discharge, and bagging in one machine, then want a catcher that handles the mess without constant stopping.
Upsides
- Self-propelled drive eases the pace on longer mowing sessions.
- 1.4-bushel catcher gives you a more practical bagging setup.
- Three cutting styles make seasonal cleanup easier to match.
- Six cutting positions help you fine-tune the finish.
- 21-inch deck keeps the mower compact enough for normal suburban storage.
Worth Noting
- The catcher adds a little more emptying and maintenance work than a mulch-only mower.
- As with most bagging setups, wet clippings can slow things down.

Another Choice May Suit
SENIX 22-Inch Variable Speed Rear Wheel Self Propelled Gas Lawn Mower suits thicker or more demanding lawns where extra engine output feels worth it.
Rear-wheel drive and a steel deck give this PowerSmart a familiar workhorse feel, especially for yard chores that repeat every week. Compared with the AMERISUN above, it reads a little more stripped back, but that can be a strength for homeowners who want fewer moving parts to think about.
The 170cc OHV engine and 21-inch width make it a sensible middle ground for everyday mowing on lawns that are not tiny, but not sprawling either. In most suburban settings, that balance is the point, because you get traction and coverage without stepping into the bulk of the wider 22-inch machines.
Highlights
- Rear-wheel drive helps on uneven or slightly sloped ground.
- Steel deck should hold up well to regular yard use.
- 21-inch cutting width keeps maneuvering fairly easy.
- Three mowing modes support mulch, bag, and discharge jobs.
Points To Note
- The feature set is simpler than the more accessorized mower above.
- Steel decks call for routine cleanup after cutting damp grass.
- The 21-inch deck may feel a touch slower on wider properties.
Feature Card
Made For
You fit this mower well when you want a durable, straightforward self-propelled machine for regular yard upkeep.
Where A Sibling Pick Shines
PowerSmart 22-Inch 170cc Self Propelled Gas Lawn Mower works better for larger lawns that benefit from a wider deck and a little more traction-focused help.
This 22-inch PowerSmart leans into convenience, because rear discharge joins the usual mulch and bag options. That makes it useful for busy yards where you want to move quickly through taller grass and keep the workflow simple, especially compared with the more basic 21-inch models.
The six cutting heights give you the usual seasonal flexibility, and the self-propelled format takes the pressure off on longer passes. You may find it a better fit than the 21-inch runner-up above when your mowing routine includes heavier clipping loads or a yard that changes character from one month to the next.
Bright Spots
- Rear discharge gives you another way to manage clippings.
- 22-inch deck helps cover more ground with fewer passes.
- Self-propelled design eases the work during longer sessions.
- Six height settings support seasonal mowing changes.
Softer Spots
- The larger footprint can feel less convenient in cramped storage spaces.
- Rear discharge is useful, but it still leaves you with more clipping management than mulching alone.
- Routine deck cleanup helps preserve smooth flow after heavy mowing days.

Look Elsewhere When
PowerSmart EasyGlide 21-Inch Gas Lawn Mower suits smaller, simpler yards where a push mower takes up less space and effort.
The 201cc engine gives this SENIX a noticeably stronger spec sheet than the 170cc and 144cc models above, and the variable-speed rear-wheel drive adds more control over pace. That combination makes sense for larger yards, thicker growth, or long mow days where a little extra muscle feels welcome.
It still keeps the familiar 3-in-1 layout, so you can bag, mulch, or side-discharge without changing the machine’s basic purpose. One thing worth considering, though, is that the stronger setup makes the mower feel better suited to demanding lawns than to tiny city plots where lighter equipment is easier to park.
Reasons To Buy
- 201cc engine offers the strongest output in this group.
- Variable speed gives you more control over your walking pace.
- Rear-wheel drive helps the mower stay composed on uneven turf.
- Three cutting modes keep the mower flexible for different cleanup tasks.
- 22-inch deck covers more lawn per pass.
Areas To Watch
- The stronger build can feel like more mower than a small yard needs.
- Larger equipment usually asks for a little more storage room.
- Cleaning the deck after dense grass helps keep performance steady.
Spec Overview
The Right Fit
You fit this mower best when your yard runs larger, thicker, or more demanding than average.
Not Your Match When
PowerSmart EasyCut 18-Inch Gas Lawn Mower is the better choice for a smaller property where compact handling matters more than engine strength.
The 18-inch deck makes this the most space-friendly mower here, and that matters for narrow side yards, smaller storage sheds, and tighter turning areas. Compared with the 21-inch and 22-inch models above, it asks less of your storage space and gives you a lighter, more manageable footprint.
The 144cc four-stroke OHV engine and push format keep it straightforward for small lots and routine trims. That said, it makes the most sense when you value easy handling over speed, because a smaller deck means more passes on broader lawns.
Best Bits
- 18-inch deck helps in narrow and crowded spaces.
- Push design stays simple and easy to understand.
- Three cutting modes give you useful everyday flexibility.
- Six height settings help you adapt the cut through the season.
Small Caveats
- The smaller deck means more passes on wider lawns.
- Push mowing asks more of you than the self-propelled options in this guide.
- Steel deck upkeep matters after wet clipping days.

Built With In Mind
You suit this mower best when your yard is compact and you want something easy to steer and store.
Where A Sibling Pick Shines
SENIX 22-Inch Variable Speed Rear Wheel Self Propelled Gas Lawn Mower is the better match for larger, tougher lawns that need more power and drive help.
How To Choose The Right Gas Lawn Mower Self-Propelleds
Match Deck Size To Your Yard
Deck width sets the pace of the whole job. An 18-inch mower turns more easily in narrow passages, while 21-inch and 22-inch decks shave down the number of passes on open lawns.
You also want to think about storage. A wider mower can feel like a cart in a hallway-sized shed, while a smaller frame slips into tighter corners with less fuss.
Choose Drive Type For Your Terrain
Rear-wheel drive helps on slopes and rough grass because the driven wheels sit under more of the mower’s weight. That setup shows up in the PowerSmart 22-inch and SENIX models, which makes sense for yards that are not perfectly flat.
Push mowers still have a place, though. They keep the machine simpler and lighter, which works nicely for level lawns where you want direct steering more than drive assistance.
Think Beyond Engine Size Alone
CC rating, or cubic centimeters, describes engine displacement, which gives you a rough sense of engine capacity. A 201cc mower like the SENIX usually suits tougher work better than a 144cc model, but the rest of the design still matters.
Deck size, drive setup, and cutting mode often change the experience just as much as raw displacement. For a thick, long lawn, a bigger engine helps, but a smart cut path and the right drive layout often matter just as much.
Pick The Cutting Modes You’ll Actually Use
Mulching chops clippings into smaller bits and leaves them on the lawn, bagging gathers them, and side or rear discharge sends them out of the deck for faster mowing. The right mix depends on how tidy you want the yard to look and how much cleanup you want later.
Busy households often lean toward 3-in-1 models because one mower can handle cleanup, trimming, and seasonal shifts. That flexibility is handy, but a simpler mower can still be the better call for a small lawn that stays easy to maintain.
A Quick Reality Check Before You Choose
Mistakes Worth Dodging
Shoppers often focus on engine size and forget storage, turning radius, and how much ground they actually mow. A bigger deck sounds helpful until you need to work around fences, trees, and narrow side paths.
Another common miss is choosing a push mower for a yard that really wants drive assistance. That mismatch turns Saturday mowing into a longer chore than it needs to be.
The Upgrade Payoff
Higher-tier mowers usually spend the extra money on stronger engines, variable-speed drive systems, wider decks, and better clipping control. Those additions matter most on larger lots, rough ground, or lawns that see a lot of seasonal growth.
Spending more also tends to make sense when you mow often and want less strain over time. For a small, level yard, the extra hardware can feel unnecessary, but for a bigger property, it often pays back in time and comfort.
Frequently Asked Questions
What Does Self-Propelled Mean On A Gas Mower?
The mower moves forward under its own drive, so you guide more than you push. That matters most on hills, thick grass, and longer mowing sessions.
Is A 22-Inch Deck Better Than A 21-Inch Deck?
A 22-inch deck covers more grass with each pass, which helps on open lawns. A 21-inch deck can feel easier to steer in tighter spaces.
Why Choose Rear-Wheel Drive?
Rear-wheel drive usually gives better traction on slopes and uneven spots. It also helps the mower stay more planted when the grass gets dense.
Do Three Cutting Modes Really Matter?
They matter a lot when your yard changes through the season. Mulching, bagging, and discharge each solve a different mowing problem.
What Engine Size Works For Most Home Lawns?
A 144cc or 170cc mower fits many routine lawns well. A 201cc model makes more sense for heavier grass or larger properties.
Closing Thoughts
You have a solid spread here, from compact push mowers to stronger rear-wheel-drive machines built for rougher lawns. The right choice comes down to how much ground you cover, how much slope you face, and how much clipping control you want after each cut. PowerSmart covers the middle of the market well, while SENIX pushes farther for tougher jobs. Match the mower to your yard, and the whole routine gets easier.
