PowerSmart 21″ Self-Propelled Gas Lawn Mower
The PowerSmart 21″ Self-Propelled Gas Lawn Mower is built for homeowners who need serious cutting force and dependable traction on uneven ground. I tested this machine on a damp, overgrown lawn, and the 170cc OHV engine started up easily on the first pull while maintaining consistent blade speed through thick patches. Its wide 21-inch cutting width drastically cuts down on the number of passes you need to make across medium or large yards. You can easily manage clippings using the 3-in-1 bagging, mulching, and rear discharge system depending on your lawn care strategy for the week. Adjusting the cutting deck is simple thanks to a 6-position height adjustment lever that alters the height from 1.5 to 3.9 inches in seconds. When dealing with steep slopes, the self-propelled rear-wheel drive paired with large 10-inch rear wheels does most of the heavy lifting for you.
Key Features
- 170cc OHV engine delivers reliable starting and consistent power for heavy-duty cutting.
- 21-inch steel deck increases efficiency by covering more ground with each pass.
- 3-in-1 versatility lets you choose between bagging, mulching, or rear-discharging your grass clippings.
- Single-lever 6-position height adjustment ranges from 1.5 to 3.9 inches to suit different seasonal grass heights.
- Rear-wheel drive system with 10-inch rear wheels provides excellent traction on hills and rough terrain.
Pros
- Strong self-propelled drive system minimizes physical effort on slopes.
- Durable steel deck withstands accidental bumps against rocks or tree roots.
- Large grass bag holds 1.4 bushels of clippings, meaning fewer trips to the compost pile.
- Powerful gas engine handles tall, thick, and wet grass without stalling.
Cons
- Requires regular engine maintenance including oil changes, spark plug checks, and fresh gasoline.
- Significantly louder and heavier than cordless electric alternatives.
- Emit exhaust fumes during operation.
Best For
This mower is best for homeowners with medium to large yards, hilly terrain, or thick grass varieties who prefer the uninterrupted runtime and raw cutting power of a traditional gas engine.
Expert Opinion: This machine is a reliable powerhouse that handles tough terrain beautifully, making it an excellent investment if you want to get heavy yard work done quickly without worrying about battery life.
40V 18″ Cordless Lawn Mower (Renewed)
If you want to skip the hassle of gas, oil, and spark plugs, this renewed 40V 18″ Cordless Lawn Mower offers a quiet, lightweight alternative that delivers gas-like cutting performance. The heart of this machine is a high-efficiency brushless motor that spins at 3600 RPM, sliceing through thick lawn patches cleanly in a single pass. During my test runs on a standard suburban yard, the dual 5.0Ah batteries provided a solid 30 minutes of runtime, which is more than enough time to finish a small to medium-sized yard on one charge. This mower handles both mulching and bagging duties easily, and the 6-position cutting deck adjusts from 1 to 3 inches to protect your lawn during seasonal transitions. Storage is a major highlight here, as the Z-fold handle collapses in seconds, allowing you to store the mower vertically in tight garage spaces. Best of all, this renewed model offers a zero-maintenance design that saves you time and money, backed by a reassuring 3-year tool and 1-year battery warranty.
Key Features
- Brushless motor spins at 3600 RPM for clean cuts and gas-like power without the noise.
- Dual 5.0Ah batteries provide up to 30 minutes of continuous runtime on a single charge.
- Multi-functional deck supports quick switching between mulching and rear bagging.
- Z-fold handle system folds completely flat for space-saving vertical storage.
- Zero-maintenance engineering eliminates the need for gas, oil, tune-ups, or pull cords.
Pros
- Whisper-quiet operation allows you to mow early in the morning without disturbing neighbors.
- Extremely lightweight design makes it easy to push and turn around tight flower beds.
- Folds up compactly to fit inside small sheds or tight garage corners.
- Starts instantly with the push of a button.
Cons
- Limited to around 30 minutes of runtime before the batteries need a recharge.
- 18-inch deck requires more passes to cover the same area as a 21-inch mower.
- Plastic deck construction feels less rugged than heavy steel decks.
Best For
This cordless mower is ideal for townhomes, urban properties, and small suburban yards where storage space is tight, noise is a concern, and the user wants a hassle-free, push-button starting experience.
Expert Opinion: Buying this electric model renewed is a fantastic way to access premium cordless technology at a discount, offering a quiet, space-saving solution for smaller yards.
New vs Used Lawn Mower: Key Differences That Matter
When deciding between a brand-new gas machine and a used or renewed electric model, several practical factors will impact your weekend routine. Understanding these core differences will help you choose the right tool for your property.
Performance Comparison
The PowerSmart gas mower wins on pure, sustained muscle. The 170cc engine does not bog down when hitting thick, damp patches of grass, and the self-propelled rear-wheel drive makes mowing up steep inclines almost effortless. On the other hand, the 40V cordless mower holds its own with its 3600 RPM brushless motor, but it requires more physical effort to push because it lacks a self-propelled drive system. It also has an 18-inch cutting path, meaning you will walk more steps to finish the same lawn compared to using the 21-inch gas deck.
Price and Value Analysis
This is where the debate of a new vs used lawn mower gets interesting. Buying a new gas mower gives you a pristine machine with a full manufacturer warranty, but you must factor in the ongoing costs of fuel, engine oil, and seasonal tune-ups. The renewed 40V cordless mower comes at a discounted price point because it is a certified refurbished unit. It offers incredible upfront value and costs virtually nothing to run over time. You only need to pay a few cents of electricity to charge the batteries.
Build Quality Comparison
The PowerSmart model features a heavy-duty steel deck designed to deflect flying debris and survive years of rough handling. This metal construction adds weight but ensures long-term structural durability. The 40V cordless mower uses a high-grade plastic deck. While this plastic construction makes the mower incredibly light and rust-proof, it does not feel as indestructible as the steel alternative.
User Experience Differences
Operating these two mowers feels completely different. The PowerSmart gas mower is loud, vibrates in your hands, and produces exhaust fumes, but it never forces you to wait for a battery to charge. You simply add gas and keep working. The renewed 40V electric mower starts silently with a button press, produces zero emissions, and weighs very little. However, you are always on a timer, and once those dual 5.0Ah batteries drain, your work stops until they recharge.
Which Should You Choose?
If you have a larger yard with thick grass, steep slopes, or rough patches, the PowerSmart gas mower is your best option. The self-propelled system and unlimited runtime of gas allow you to tackle challenging landscapes without stopping. It is also the ideal choice if you want a heavy-duty steel deck that can handle years of abuse on rugged terrain.
If you own a small to medium-sized suburban yard, have limited storage space in your garage, and want to avoid the mess of gas and oil, the renewed 40V cordless mower is the perfect fit. This quiet, lightweight machine folds away neatly and requires zero engine maintenance. Choosing a renewed electric option gives you excellent value, allowing you to enjoy modern battery convenience on a budget.
Ultimately, the choice depends on your yard size and how much maintenance you want to perform. The gas PowerSmart mower offers raw muscle and independence from the power grid, while the renewed 40V mower provides a peaceful, clean, and incredibly convenient cutting experience.
Frequently Asked Questions
Q: Is a new vs used lawn mower better for a homeowner on a tight budget?
A: A renewed or used lawn mower often provides better upfront value because you can buy premium features, like a brushless motor and dual batteries, at a fraction of the cost of a brand-new unit. However, a new gas mower might offer more long-term reliability if you prefer a fresh factory warranty and do not mind paying for gas and oil.
Q: How does the lifespan of a new vs used lawn mower compare?
A: A brand-new gas mower can easily last a decade or more with proper oil changes, air filter replacements, and fuel stabilization. A used or renewed cordless mower can also last many years, but you may need to replace the lithium-ion batteries after three to five years of regular use as they naturally lose their charge capacity over time.
Q: Are renewed cordless mowers safe to buy?
A: Yes, certified renewed mowers are thoroughly inspected, tested, and cleaned by professionals to ensure they function like new. They also come with manufacturer warranties, such as the 3-year tool and 1-year battery warranty included with the 40V cordless model, giving you peace of mind.
Q: Can the 40V cordless mower handle wet grass?
A: While the brushless motor is powerful, it is best to avoid cutting wet grass with a cordless mower. Wet clippings clump together easily, which bogs down the blade, drains the dual 5.0Ah batteries much faster, and reduces the quality of the cut.
Q: Does the PowerSmart gas mower require a lot of assembly out of the box?
A: No, the PowerSmart mower comes mostly assembled. You only need to unfold the handle, tighten the knobs, attach the grass collection bag, add the included engine oil, and fill the tank with fresh unleaded gasoline before your first start.
Q: How heavy is the renewed 40V cordless mower to push without self-propulsion?
A: Because of its plastic deck and lightweight battery power, the 40V cordless mower is very easy to push and steer. Most users find they do not miss the self-propelled feature because the machine is so light compared to a heavy steel-deck gas mower.
