Updated July 2026 — full head-to-head comparison.
Design and Build Quality
When it comes to design and build quality, the AMERISUN 21-Inch Gas Push Lawn Mower is significantly different from the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower. The AMERISUN features a durable steel cutting deck that boasts a 21-inch width, which is ideal for small to medium-sized lawns. Weighing in at 68 lbs, it is designed for easy maneuverability, especially around obstacles. In contrast, the Greenworks mower features a sleek design powered by a brushless motor and is cordless, providing a modern touch. Its IPX4-rated waterproof construction ensures durability against the elements, making it a reliable choice for various weather conditions.
Engine and Power
The AMERISUN mower is powered by a robust 144cc 4-cycle OHV engine, which delivers consistent cutting performance for yards of varying sizes. This gas-powered option provides a traditional mowing experience with the advantage of an easy pull-start system. On the other hand, the Greenworks mower is battery-powered with a 60V brushless motor. It can deliver gas-like power for up to 3/4 acre per charge, making it suitable for larger yards. While the AMERISUN operates on traditional gasoline, the Greenworks offers a maintenance-free experience with zero emissions, making it a more eco-friendly choice.
Cutting Performance
Cutting performance is a key consideration for lawn mowers, and both models offer versatile options. The AMERISUN features a 3-in-1 functionality, allowing for mulching, bagging, and side discharge options. It also has a 6-level height adjustment ranging from 1.5" to 3.9", allowing users to customize their cuts based on grass type and seasonal conditions. In comparison, the Greenworks mower also provides a 4-in-1 cutting versatility, including mulch, bag, side discharge, and turbo leaf pickup. With 7 height settings, it gives users even more control over their mowing experience, which can be particularly beneficial for varied terrain.
Ease of Use
The AMERISUN is designed to be lightweight and easy to maneuver, making it user-friendly, especially for those who prefer push mowers. Its foldable handle allows for compact storage, which is a bonus for users with limited space. Conversely, the Greenworks mower is self-propelled, which significantly reduces the physical effort required to navigate through thick grass or slopes. This feature, paired with its adjustable pace control, provides an effortless mowing experience. For users who may struggle with traditional push mowers, the self-propelled design of the Greenworks presents a distinct advantage.
Noise Levels
The AMERISUN, as a gas-powered mower, operates at traditional noise levels associated with such equipment, which may be disruptive in noise-sensitive neighborhoods. In contrast, the Greenworks mower operates three times quieter than gas mowers, allowing for early morning mowing without disturbing neighbors. Its maintenance-free design also means no fuel to handle, making it an appealing option for those who prefer a quieter, more eco-friendly lawn care solution.
Price Comparison
In terms of pricing, the AMERISUN is currently available for $238.49, making it about 56% cheaper than the Greenworks mower, which retails for $538.00. This price difference of $299.51 may appeal to budget-conscious consumers looking for a reliable lawn mower without the added features of a self-propelled and battery-powered model. However, the Greenworks mower's price reflects its advanced technology and versatility, which could justify the investment for many homeowners.
Sales Rank and Popularity
When considering popularity, the AMERISUN has a sales rank of 8653, while the Greenworks mower ranks higher at 5665. This suggests that the Greenworks model is more popular among consumers, likely due to its modern features and convenience. The higher sales rank may indicate a growing trend towards battery-powered lawn care solutions, especially among environmentally conscious homeowners.
Which should you buy?
Choosing between the AMERISUN 21-Inch Gas Push Lawn Mower and the Greenworks 60V 21" Self-Propelled Cordless Lawn Mower ultimately depends on your specific needs and budget. If you prioritize cost-effectiveness and traditional mowing capabilities, the AMERISUN offers solid performance at a much lower price. However, if you're looking for convenience, quieter operation, and eco-friendliness, the Greenworks mower provides advanced features and greater ease of use, making it worth the investment for many homeowners.
