Price Comparison

The AMERISUN 21-Inch 3IN1 Gas Push Lawn Mower is priced at $238.49, while the LawnMaster Electric Lawn Mower is significantly cheaper at $134.99. This makes the LawnMaster about 43.5% cheaper than the AMERISUN mower. If budget is your primary concern, the LawnMaster offers a compelling option without sacrificing key features. However, it's important to consider what you’re getting for that price difference in terms of performance and capabilities.

Engine and Power

The AMERISUN mower features a robust 144cc 4-cycle OHV engine, which is designed for high efficiency and consistent cutting performance. This powerful engine allows for effective mowing of small to medium-sized lawns, making it suitable for those who prioritize robust gas-powered performance. In contrast, the LawnMaster is equipped with a 12AMP electric motor that runs at a speed of 3600 RPM. While it may lack the raw power of the AMERISUN, the LawnMaster’s electric motor is ideal for homeowners looking for an eco-friendly option with minimal maintenance.

Cutting Width and Deck Durability

When it comes to cutting width, the AMERISUN lawn mower offers a substantial 21-inch cutting deck, suitable for reducing mowing time and providing even coverage. The durable steel deck is built to withstand tough conditions, making it reliable for thick grass. On the other hand, the LawnMaster has a slightly smaller 19-inch cutting width but boasts a high-impact rust-resistant deck. While both mowers offer durability, the AMERISUN’s larger cutting area can enhance efficiency for larger lawns.

Versatility and Features

The AMERISUN mower excels in versatility with its 3-in-1 functionality: mulching, bagging, and side discharge. This allows users to choose the best option based on their lawn care needs, complete with a large-capacity 1.4-bushel grass catcher to minimize emptying frequency. Conversely, the LawnMaster offers a simpler 2-in-1 function, allowing for either mulching or side discharge. While both mowers provide useful features, the AMERISUN's additional options can be particularly beneficial for those who want flexibility in lawn care.

Height Adjustment Options

With the AMERISUN, users have access to 6-position height adjustments ranging from 1.5 inches to 3.9 inches. This level of customization is advantageous for managing different grass types and seasonal conditions. The LawnMaster also features 6 cutting positions, adjustable from 1.5 inches to 4 inches, which offers similar flexibility. However, the AMERISUN’s lower maximum height could be a slight drawback for users looking to maintain particularly tall grass.

Weight and Maneuverability

The AMERISUN weighs in at 68 lbs, which may be a concern for some users regarding maneuverability. Despite this, it features durable wheels that provide stability during operation. In contrast, the LawnMaster is much lighter at only 35 lbs, making it easier to maneuver around obstacles. Its wheels are also designed for easy rotation, which enhances control during use. For those prioritizing lightweight handling, the LawnMaster is clearly the superior choice.

Sales Performance

In terms of sales rank, the AMERISUN ranks at 8653, while the LawnMaster holds a rank of 15288. While the AMERISUN is the more popular choice among consumers, it is essential to consider what features and specifications drive that preference. The AMERISUN’s higher sales rank could be indicative of its performance capabilities and durability, appealing to a segment of the market looking for a reliable gas mower.

Which should you buy?

Choosing between the AMERISUN 21-Inch 3IN1 Gas Push Lawn Mower and the LawnMaster Electric Lawn Mower ultimately depends on your specific needs. If you are looking for a powerful, versatile mower capable of handling various lawn conditions, and you don’t mind paying a premium, the AMERISUN is a solid choice. However, if budget constraints are a priority and you prefer a lighter, more eco-friendly option, the LawnMaster provides excellent value at about 43.5% less than the AMERISUN. Each has its strengths, so weigh your priorities carefully before making a decision.
