Updated July 2026 — full head-to-head comparison.

Overview of the Earthwise 1715-16EW and SENIX 20" Gas Lawn Mower

The Earthwise 1715-16EW is priced at $122.99, while the SENIX 20" Gas Lawn Mower costs $199.99, making the Earthwise about 38% cheaper. The two mowers cater to different user preferences, one focusing on eco-friendliness and manual operation, while the other leans towards power and efficiency.

The Earthwise is a hand-push reel mower with a cutting width of 16 inches and features a 7-blade ball bearing reel, designed for quieter operation without emissions. In contrast, the SENIX boasts a 20-inch cutting width powered by a 144 cc gas engine, delivering explosive power for larger mowing tasks.

Cutting Width and Efficiency

The SENIX offers a significantly wider cutting width of 20 inches, compared to the Earthwise's 16 inches. This difference means that the SENIX can cover more ground in a single pass, enhancing operational efficiency for larger lawns.

In practical terms, the 20-inch blade of the SENIX allows users to complete their mowing tasks more quickly, especially on extensive properties. Meanwhile, the Earthwise is ideal for smaller lawns and provides a clean cut with its 7-blade system, making it suitable for precise mowing in tighter spaces.

Power Source and Operation

The Earthwise relies entirely on human power, making it an environmentally friendly option with no gas emissions. It is perfect for those who prioritize sustainability and enjoy the exercise that comes with pushing a reel mower.

On the other hand, the SENIX features a 144 cc 4-cycle gas engine, providing more power to tackle rugged terrains and slopes. This engine allows it to operate efficiently across various grass heights, which can be particularly advantageous for users with larger or uneven lawns.

Adjustability and Versatility

When it comes to adjustability, the SENIX offers three cutting height options ranging from 1.35 inches to 3.15 inches. This feature allows users to adapt their mowing height according to the specific grass type and lawn conditions they are dealing with.

The Earthwise allows for an adjustable cutting height from 0.5 inches to 2.5 inches, providing a clean, even cut suitable for different grass types. While both mowers offer height adjustability, the SENIX's broader range may appeal to those who require more flexibility in cutting heights.

Maneuverability and Design

The Earthwise's design features ten-inch composite wheels, allowing for easy maneuverability on various surfaces. Its lightweight construction makes it easy to push, making it a great choice for those who may struggle with heavier equipment.

Conversely, the SENIX includes a 7-inch wheel design that enhances its passability across rugged terrains. While both mowers are push models, the SENIX’s wheels are specifically designed to tackle slopes and uneven ground, making it more versatile for users with varied lawn conditions.

Maintenance and Durability

One of the key advantages of the Earthwise is its low maintenance requirement. With no gas engine, users don’t have to worry about fuel costs or engine upkeep, making it a convenient option for those looking for a mower that is almost maintenance-free.

In contrast, the SENIX, while powerful, does require more maintenance typical of gas-powered equipment, including oil changes and regular engine check-ups. However, it also comes with a two-year warranty, providing peace of mind for potential maintenance issues.

Price Comparison

The Earthwise is priced at $122.99, while the SENIX is at $199.99, which makes the SENIX about 63% more expensive. For budget-conscious buyers, the Earthwise presents a compelling option, especially for smaller lawns where a reel mower's efficiency can shine without the need for gas power.

However, those willing to invest more might find the SENIX's power and efficiency worth the higher price, especially if they have larger lawns that require quicker mowing solutions.

Which should you buy?

Deciding between the Earthwise 1715-16EW and the SENIX 20" Gas Lawn Mower ultimately depends on your specific needs and preferences. If you're looking for an eco-friendly, cost-effective solution for a smaller lawn, the Earthwise is a fantastic choice. However, if you have a larger area that requires robust power and efficiency, the SENIX is worth the investment. Each mower has its strengths, catering to different users, making it essential to consider your lawn size, terrain, and maintenance preferences before making a decision.
