The AMERISUN 21 Inch Gas Push Lawn Mower is an excellent choice for homeowners looking for a reliable gas-powered mower. Priced at $224.99, it is about 13% cheaper than its competitor, the BLACK+DECKER 20-Inch Corded Electric Lawn Mower, which retails for $259. This mower features a 144cc 4-stroke OHV engine, providing consistent cutting performance for small to medium yards. With a cutting width of 21 inches, it aims to reduce mowing time, making it ideal for suburban lawns.
Overview of the BLACK+DECKER 20-Inch Corded Electric Lawn Mower
The BLACK+DECKER 20-Inch Corded Electric Lawn Mower is priced at $259, making it a bit more expensive than the AMERISUN mower. However, it boasts a 13 Amp motor that is designed to tackle thick grass and overgrowth effectively. This electric mower offers three different mowing modes: mulching, bagging, and side discharge, enhancing its versatility. Additionally, its EdgeMax deck design allows for close cutting up to edges, making it a practical choice for homeowners who want a clean finish around borders.
Performance and Power
When it comes to performance, the AMERISUN mower's gas-powered 144cc engine delivers powerful cutting capabilities, making it suitable for various grass types and conditions. Its robust engine allows for a reliable recoil start, ensuring you can get to work quickly. In contrast, the BLACK+DECKER electric mower, while slightly less powerful, offers sufficient power through its 13 Amp motor, enabling it to handle thick grass effectively. Both mowers cater to different preferences—those who favor the consistent power of gas versus the convenience of electric.
Cutting Options and Versatility
The AMERISUN model features a 2-in-1 mulching and side discharge option, allowing users to easily switch between cutting styles for different yard needs. This flexibility is particularly advantageous during seasonal growth when grass may be denser. On the other hand, the BLACK+DECKER mower excels in versatility with its 3-in-1 functionality, allowing for mulching, bagging, and side discharge. The ability to bag grass clippings in a 13-gallon fabric grass bag adds convenience for those who prefer a tidy lawn.
Height Adjustment Mechanisms
Height adjustment is crucial for achieving the perfect cut, and both mowers offer easy adjustment options. The AMERISUN mower has a 6-position height adjustment that ranges from 1.5 to 3.9 inches, allowing for tailored cutting based on grass type and conditions. Conversely, the BLACK+DECKER mower features a single lever that adjusts the cutting height across 7 settings, ranging from 1.5 inches to 4 inches. This additional setting may provide more customization for users who want specific heights for their lawns.
Weight and Storage
In terms of weight, the AMERISUN mower weighs only 63 pounds, making it relatively lightweight and easy to maneuver. Its foldable design further enhances portability and storage convenience, allowing it to fit easily in garages or sheds. The BLACK+DECKER mower, while designed to be ultra-light, does not specify a weight; however, its compact design also facilitates easy transport and storage. Both models cater to users who prioritize convenient handling and storage solutions.
Maintenance and Warranty
Maintenance is an essential aspect of owning a lawn mower. The AMERISUN gas mower requires regular maintenance to ensure optimal performance, including oil changes and spark plug replacements. However, it lacks a specified warranty period. In comparison, the BLACK+DECKER mower comes with a 2-year warranty, providing peace of mind for consumers regarding potential defects and maintenance issues. This warranty can be a significant factor for buyers looking for long-term reliability.
Which should you buy?
Choosing between the AMERISUN 21 Inch Gas Push Lawn Mower and the BLACK+DECKER 20-Inch Corded Electric Lawn Mower ultimately depends on your specific needs. If you prefer a cost-effective option with a powerful gas engine, the AMERISUN mower is about 13% cheaper and offers solid performance for small to medium yards. However, if you value versatility, ease of use, and a warranty, the BLACK+DECKER mower's electric motor and 3-in-1 capabilities may justify its higher price. Each mower has unique features tailored to different preferences, making your choice a matter of personal priorities.
