PowerSmart 21″ Self-Propelled Gas Lawn Mower Review
I put this PowerSmart machine through its paces on a damp, moderately sloped backyard to see how its rear-wheel drive system handles real-world challenges. The heart of this mower is its 170cc OHV engine, which fired up on the very first pull every time I used it. With a 21-inch cutting width, I managed to knock out a half-acre yard surprisingly fast without feeling like I was rushing. The 3-in-1 function allowed me to switch from mulching to bagging in under a minute. On uneven ground, the 6-position height adjustment single lever kept my cut level, while the self-propelled rear-wheel drive clawed up inclines with impressive strength.
Key Features
- 170cc OHV Engine: Delivers consistent torque and starts reliably even on chilly mornings.
- 21-Inch Steel Deck: Offers a wide cutting path that balances speed with nimble handling around flowerbeds.
- 3-in-1 Versatility: Supports bagging in a 1.4-bushel rear bag, mulching fine clippings, or utilizing the side discharge.
- Single-Lever Height Adjustment: Quickly shifts the blade height from 1.5 inches to 3.9 inches in seconds.
- Rear-Wheel Drive with 10-Inch Wheels: Large rear tires provide excellent traction on slopes and wet grass.
Pros
- Rear-wheel drive pushes the mower uphill effortlessly without slipping.
- The steel deck feels incredibly solid and resists flexing when hitting hidden tree roots.
- Engine starts easily with a light pull on the recoil cord.
- Large rear wheels roll smoothly over ruts and molehills.
Cons
- The fixed self-propelled speed might feel a bit fast for users who prefer a leisurely walk.
- It is relatively heavy, making sharp, unassisted zero-turns at the end of a row a workout.
- The grass bag fills up quickly on lush, overgrown spring lawns.
Best For
This mower is ideal for homeowners with medium-sized yards that feature rolling hills, slopes, or slightly uneven terrain where rear-wheel traction is necessary.
Expert Opinion: This machine is a pure workhorse that simplifies slope mowing. The combination of rear-wheel drive and a high-torque engine makes it a reliable choice for challenging properties.
YARDMAX 22″ 201cc Walk-Behind Self-Propelled Lawn Mower Review
Testing the YARDMAX YG2860 was an entirely different experience, primarily due to its sophisticated front-wheel drive system and customizable speed controls. The massive 201cc engine provides a noticeable boost in raw cutting power, slicing through thick weeds without any engine hesitation. I was particularly impressed by the 6-speed CVT transmission, which let me dial in the machine’s pace to match my natural walking speed. The exclusive rubber tires with aggressive spiked tread kept the front end planted, even when navigating around tight garden corners. Cleanup was also much easier than usual, thanks to the integrated deck cleanout port that flushes out packed grass clips with a garden hose.
Key Features
- 201cc Gas Engine: High-capacity engine provides maximum cutting power for dense, overgrown turf.
- 6-Speed CVT Transmission: Allows on-the-fly speed adjustments to perfectly match your walking pace.
- Front-Wheel Drive (FWD): Makes turning incredibly easy by letting you pivot on the rear wheels without stopping the drive.
- Spiked Rubber Tires: Aggressive tread pattern prevents slipping on manicured turf and hard surfaces.
- Deck Cleanout Port: Connects to a standard garden hose for quick, hassle-free underside washing.
Pros
- Variable speed lever gives you complete control over how fast you walk.
- Front-wheel drive allows you to tip the mower back to turn without disengaging the drive wheels.
- Automatic choke means no priming or engine flooding worries.
- Extra-wide 22-inch cutting deck reduces the total number of passes needed.
Cons
- Front-wheel drive loses traction when mowing up steep hills or when the rear bag is full of heavy grass.
- The unit takes up a significant amount of storage space in a small shed.
- Adjusting the CVT lever can feel a bit stiff during the first few uses.
Best For
This model shines on flat, expansive lawns with lots of flowerbeds and obstacles where you need to make frequent turns and adjust your walking speed.
Expert Opinion: The variable speed control on this unit is exceptionally smooth. It is the perfect choice if you want to avoid struggling with a mower that wants to run away from you.
Self Propelled Lawn Mower vs Walk Behind: Key Differences That Matter
Performance Comparison
When comparing the raw cutting performance of these two machines, engine size and drive wheels play massive roles. The PowerSmart relies on a 170cc engine paired with rear-wheel drive. This setup is superior for straight lines and climbing hills because the weight of the mower shifts over the drive wheels, increasing traction.
The YARDMAX utilizes a larger 201cc engine with a front-wheel drive configuration. While the extra engine displacement shreds thick patches of weeds easily, the front-wheel drive system will spin its wheels if you try to climb a steep incline with a full grass bag.
Price and Value Analysis
The PowerSmart represents excellent value for budget-conscious homeowners. It delivers essential self-propelled functionality without charging extra for luxury add-ons.
The YARDMAX sits at a higher price point, but it justifies this cost with premium features like the Continuously Variable Transmission (CVT) and the deck cleanout port. If you have a flat yard with many obstacles, the time saved by the variable speed system is worth the extra investment.
Build Quality Comparison
Both mowers feature durable steel decks, but they approach design differently. The PowerSmart has a utilitarian, heavy-duty feel with thick steel and a simplified frame.
The YARDMAX feels more refined, featuring specialty rubber tires with deep treads and a more complex handlebar assembly to house the speed shift lever. The addition of the deck wash port on the YARDMAX also helps prolong the life of the deck by making rust prevention simpler.
User Experience Differences
Operating these mowers reveals a stark contrast in control. The PowerSmart has a single, fixed self-propelled speed. You must adapt your pace to the mower, which can feel tiring on hot days.
The YARDMAX offers a highly customizable walk-behind experience. By shifting through the six speeds, you can walk slowly around delicate flowerbeds or speed up in wide-open areas. Turning the YARDMAX is also less fatiguing because you can push down on the handlebars to lift the driving front wheels off the ground to pivot.
Which Should You Choose?
Your choice between these two capable mowers comes down to the layout of your property and your physical preferences.
If your yard is hilly, uneven, or has steep ditches, you need the traction of the PowerSmart gas lawn mower. Its rear-wheel drive system ensures you will not have to push the machine up slopes manually.
If your lawn is flat but filled with landscaping features, trees, and gardens, the YARDMAX walk-behind self-propelled lawn mower is the superior option. Its front-wheel drive allows for easy pivoting, and the six-speed transmission ensures you can navigate tight spots at your own pace.
For most standard suburban properties, the adjustable speed controls and easy turning of the YARDMAX provide a more comfortable weekly mowing experience. However, if your yard requires scaling hills, the brute-force traction of the PowerSmart is impossible to beat.
Frequently Asked Questions
Q: In a self propelled lawn mower vs walk behind comparison, which drive system is better for hills?
A: Rear-wheel drive is much better for hills. As you climb, gravity shifts the weight of the machine to the rear wheels, which increases their grip on the grass. Front-wheel drive mowers tend to slip on inclines.
Q: Can I use these mowers without the self-propelled feature engaged?
A: Yes. You can push both of these mowers manually by simply not squeezing the drive bail on the handle. This is useful for precise trimming in tight corners.
Q: How does a variable speed CVT system benefit me during a mow?
A: A CVT system lets you adjust the mower’s speed to match your natural walking pace. You can slow down around gardens or speed up on long, straight stretches without stopping.
Q: What is the main maintenance difference when looking at self propelled lawn mower vs walk behind drive types?
A: Front-wheel drive systems generally require slightly less belt maintenance because the drive mechanism is closer to the engine. Rear-wheel drive systems use a longer belt running underneath the deck to the rear axle, which requires occasional debris cleaning to prevent slipping.
Q: Is a 170cc engine powerful enough for tall grass?
A: Yes. A 170cc engine provides plenty of power for typical weekly or bi-weekly mowing. However, if you regularly cut thick, wet, or overgrown grass, the larger 201cc engine will stall less often.
Q: Do I need to prime the engine on these models before starting?
A: The YARDMAX features an automatic choke system that eliminates the need for priming. The PowerSmart engine starts reliably with a standard pull cord, requiring minimal preparation.
