The PowerSmart 22 in. 170cc Self Propelled Gas Lawn Mower brings rear-wheel drive and a sturdy steel deck to the budget-friendly segment, aiming squarely at homeowners with modest to medium-sized yards who want self-propelled convenience without paying premium brand prices.

Who Should Buy This
-
Homeowners with 1/4 to 1/3 acre lots – This mower’s 22-inch cutting deck and self-propelled rear-wheel drive handle typical suburban lawns efficiently, making it a solid match for yards that take 30-45 minutes to mow.
-
Budget-conscious buyers upgrading from a push mower – If you’re tired of pushing a non-powered mower and want self-propelled assistance without spending $400+, this is a natural step up at a very competitive price.
-
Homeowners with sloped or hilly terrain – Rear-wheel drive provides better traction on inclines than front-wheel drive models, making this a good choice for properties with gentle to moderate slopes.
-
DIYers comfortable with basic maintenance – This is a value-oriented gas mower, so expect to handle oil changes, air filter cleaning, and spark plug replacements yourself. If you’re handy with small engines, you’ll get the most out of it.
Key Features Breakdown
-
170cc PowerSmart Engine – This is a Chinese-made OHV engine that provides enough torque for typical grass conditions. It’s not a Honda or Briggs & Stratton, but it starts reliably when properly maintained and offers decent fuel efficiency. Expect to use ethanol-free gas for best results.
-
22-Inch Steel Deck – A standard width for this class, the steel construction is durable enough for residential use but adds weight. The 22-inch size strikes a good balance between maneuverability and cutting swath for medium lawns.
-
Rear-Wheel Drive Self-Propelled System – This is the standout feature at this price point. Rear-wheel drive gives you better traction on slopes and when the bagger is full. The drive engages with a simple lever on the handlebar, though it’s not variable speed—you get one speed setting.
-
3-in-1 Cutting System (Mulch, Bag, Rear Discharge) – The mower comes with a mulching plug and a rear discharge chute, plus a 1.5-bushel bag. The mulching capability is adequate for dry grass but struggles with wet or tall growth. Switching between modes is tool-free.
-
6-Position Height Adjustment – Adjustments range from about 1.5 to 3.75 inches, controlled by a single lever on the deck. This is a convenient feature that lets you quickly raise or lower the cut without bending at each wheel.
-
Folding Handle – The handle folds for compact storage, which is helpful if you have limited garage or shed space. No tools are needed for folding.
Pros
-
Exceptional value for a self-propelled mower – At $315, you’re getting rear-wheel drive and a steel deck for less than many entry-level push mowers. It’s hard to beat the price-to-feature ratio.
-
Good traction on slopes – The rear-wheel drive system provides noticeably better grip on inclines compared to front-wheel drive competitors in the same price range.
-
Simple, tool-free adjustments – Changing cutting height and switching between mulching, bagging, and discharge modes require no tools, making on-the-fly adjustments easy.
-
Reliable starting when maintained – Many users report the engine starts on the first or second pull when fresh fuel is used and the carburetor is kept clean.
-
Compact storage – The folding handle reduces the mower’s footprint, which is a real bonus for those with tight storage spaces.
-
Light enough to maneuver manually – At around 65 pounds, it’s heavier than a push mower but manageable to lift into a truck bed or push if the self-propelled drive stops working.
Cons
-
Single-speed self-propelled drive – The drive system offers only one forward speed, which feels too fast for some users and too slow for others. There’s no variable speed control, so you adapt or struggle.
-
Bag capacity is small – The 1.5-bushel bag fills up quickly, especially with thick grass. You’ll make frequent trips to the compost pile compared to mowers with 2-bushel or larger bags.
-
Engine lacks refinement – The PowerSmart engine is functional but not as smooth or quiet as premium brands. Vibration is noticeable, and the engine can bog down in heavy grass if you don’t keep the deck clean.
-
Customer support can be slow – PowerSmart’s warranty service and parts availability are not as robust as major brands. If something breaks, you may wait weeks for replacement parts.
Bottom Line
The PowerSmart 22 in. 170cc Self Propelled Gas Lawn Mower is a solid, budget-friendly choice for homeowners who want self-propelled convenience with rear-wheel drive but don’t want to spend $400+. It’s best suited for flat to gently sloped lawns of 1/4 to 1/3 acre, where the single-speed drive and small bag aren’t dealbreakers. If you’re comfortable with basic small engine maintenance and know you’re getting a value-oriented tool rather than a premium machine, this mower delivers reliable performance for the price. However, if you have a large yard, thick St. Augustine grass, or need variable speed control, consider spending more on a Honda or Toro.
Frequently Asked Questions
Q: Does this mower have a variable speed self-propelled control?
A: No, the PowerSmart 22-inch self-propelled mower uses a single-speed drive system. You engage it with a lever on the handlebar, but you cannot adjust how fast it moves. This is a common limitation at this price point.
Q: What type of oil and fuel does it take?
A: The engine requires SAE 30 weight oil (4-stroke engine oil) and regular unleaded gasoline with an octane rating of 87 or higher. PowerSmart recommends using ethanol-free gas to reduce carburetor issues. The oil capacity is about 15 ounces, and the fuel tank holds 0.9 gallons.
Q: Can I use this mower on thick, wet grass?
A: It’s not ideal. The 170cc engine can struggle with tall, damp grass, especially in mulching mode. For best results, mow when grass is dry and keep the deck clean. If you have thick Bermuda or St. Augustine, you may need to cut at a higher setting and take smaller passes.
How It Compares
Quick Verdict
The PowerSmart wins for larger, sloped, or unkempt yards, but the Greenworks is the better choice for the vast majority of suburban homeowners seeking convenience, low maintenance, and instant start-up.
Side-by-Side Comparison
| Feature | Mower A: PowerSmart 22" | Mower B: Greenworks 40V 16" |
|---|---|---|
| Price | $314.99 | $249.99 |
| Power Source | Gas (170cc) | Cordless Electric (40V, 4.0Ah) |
| Cutting Width | 22 inches | 16 inches |
| Self-Propelled | Yes (Rear-Wheel-Drive) | No (Push only) |
| Best Yard Size | 1/2 acre or more | Up to 1/3 acre |
| Warranty | 2-year limited | 4-year tool, 2-year battery |
Where PowerSmart Wins
1. Cutting Width & Speed: The 22-inch steel deck is 37% wider than the Greenworks’ 16-inch deck. This means fewer passes across the yard, significantly cutting mowing time on medium-to-large lawns. For a half-acre lot, you could save 20–30 minutes per mow.
2. Self-Propelled RWD: Rear-wheel-drive provides excellent traction on slopes and uneven terrain. If your yard has hills, thick grass, or you simply don’t want to push, the PowerSmart does the work for you. The Greenworks requires full manual pushing, which is tiring on large or sloped yards.
3. Raw Power for Tough Conditions: The 170cc gas engine delivers consistent torque for tall, wet, or overgrown grass. It can handle thick St. Augustine or Bermuda without bogging down, and the steel deck is more durable against rocks and sticks than the Greenworks’ plastic deck.
Where Greenworks Wins
1. Convenience & Zero Maintenance: Push-button start, no gas, no oil, no spark plugs, no carburetor cleaning. The Greenworks is ready instantly and requires far less upkeep. You’ll never deal with stale fuel, winterizing, or pull-cord frustration.
2. Lightweight & Maneuverable: At roughly 35–40 lbs (vs. 70+ lbs for the PowerSmart), the Greenworks is easy to lift, transport, and maneuver around flower beds, trees, and tight corners. It’s ideal for small, flat, intricate yards.
3. Lower Cost & Higher Reliability Score: At $249.99, it’s $65 cheaper. Plus, with nearly 12,000 reviews (vs. 707 for the PowerSmart), the Greenworks has a proven track record of reliability. The 4-year tool warranty also beats the PowerSmart’s 2-year coverage.
Which Should You Buy?
Buy Mower A (PowerSmart) if: You have a yard over 1/3 acre, especially if it’s sloped or has thick, heavy grass. The self-propelled drive and wide deck make mowing faster and less physically demanding. It’s also better if you don’t mind the occasional gas station trip and basic engine maintenance.
Buy Mower B (Greenworks) if: You have a flat, 1/3-acre or smaller lawn and value convenience above all. The push-button start, zero maintenance, and light weight make it perfect for quick, hassle-free mowing. It’s also the smarter choice if you already own other Greenworks 40V tools (75+ compatible).
Buy neither if: Your yard is between 1/3 and 1/2 acre with moderate slopes. The PowerSmart is overkill for small lots, and the Greenworks will struggle on hills and take too long. Instead, consider a mid-range 20–21-inch self-propelled electric mower (e.g., EGO or Ryobi) that balances power, convenience, and maneuverability.
Quick Verdict
The PowerSmart wins overall for larger, sloped, or demanding yards due to its powerful gas engine and self-propelled rear-wheel drive, while the WORX is the better choice for small, flat lawns where convenience, low noise, and zero maintenance are top priorities.
Side-by-Side Comparison
| Feature | PowerSmart 22 in. 170cc | WORX 14 in. WG779 |
|---|---|---|
| Price | $314.99 | $229.47 |
| Power Source | Gas (170cc engine) | Cordless electric (20V, 2 batteries) |
| Cutting Width | 22 inches | 14 inches |
| Self-Propelled? | Yes (rear-wheel drive) | No (push mower) |
| Best Yard Size | 1/4 to 1/2 acre | Under 1/4 acre |
| Warranty | 2-year limited | 3-year limited |
Where PowerSmart Wins
1. Cutting Power and Width
The 170cc gas engine provides consistent torque even in thick, damp grass, and the 22-inch deck cuts nearly 60% more grass per pass than the WORX’s 14-inch deck. This means significantly fewer passes and less mowing time on medium-to-large lawns.
2. Self-Propelled Drive
PowerSmart’s rear-wheel-drive self-propulsion makes mowing hills and long distances effortless—no pushing required. This is a game-changer for yards with slopes or for users who prefer not to exert physical effort while mowing.
3. 3-in-1 Versatility
You can mulch, bag, or rear-discharge clippings. Rear discharge is especially useful for tall grass or wet conditions, preventing clogging that can plague smaller electric mowers. The steel deck is also more durable than the WORX’s plastic housing.
Where WORX Wins
1. Lightweight and Easy to Store
The WORX weighs about 30 lbs—roughly half of a typical gas mower—and folds for vertical storage. It can be hung on a wall or tucked into a corner, ideal for small sheds or garages where space is tight.
2. Quieter, Cleaner Operation
Electric mowers run at a fraction of the noise level of gas engines (about 85 dB vs. 95+ dB). No exhaust fumes, no gas mixing, and no oil changes. You can mow early morning or late evening without disturbing neighbors.
3. Lower Total Cost and Maintenance
At $229 with two batteries and a charger included, the WORX costs $85 less upfront. Over time, you save on gas, oil, spark plugs, and air filters. The 3-year warranty also beats the PowerSmart’s 2-year coverage.
Which Should You Buy?
Buy Mower A (PowerSmart) if:
- Your yard is 1/4 acre or larger, especially if it has slopes or thick grass.
- You want to finish mowing quickly with a wide cutting deck and self-propulsion.
- You’re comfortable with gas engine maintenance (oil changes, fuel storage) and need the durability of a steel deck.
Buy Mower B (WORX) if:
- Your yard is under 1/4 acre, flat, and easily accessible.
- You prioritize convenience—no gas, no noise complaints, no pulling a starter cord.
- Storage space is limited, or you want a lightweight mower that’s easy to carry up steps.
Neither is ideal if:
- You have a large, complex yard with heavy brush—consider a 200cc+ gas mower or a riding mower.
- You need a mower for rough, uneven terrain—the WORX’s small wheels and plastic deck won’t hold up, and the PowerSmart’s rear-wheel drive helps but still struggles on very bumpy ground.
