Earthwise 50520 Features and Specifications

Earthwise 50520 features 20 inch (~51 cm) steel cutting deck, allowing the user to mow a rather large area quickly.

Physical dimensions of the mower are 51 x 21 x 42 inches (~130 x 53.3 x 107 cm) and despite it features a steel deck, it weighs acceptable 53 pounds (~24 kg).

Earthwise 50520 is rated at 12 Amps, allowing the unit to cut cleanly even very tough grass - just be sure that the blade is sharp or as sharp as possible. During operation, Earthwise 50520 is a very quiet unit, especially when compared with similar gas models.

No-load blade speed is 3600 rpm, while actual speed depends on the cutting height, mowing speed and of course, blade sharpness.

Like many similar models, Earthwise 50520 features 3 functions, including side discharge, mulch, and rear bag.

Handle is collapsible, saving plenty of storage space.

Front wheels feature 7 inches (~17.8 cm) and rear wheels feature 9.5 inches (24.1 cm) diameter, ensuring good maneuverability.

Cutting height may be set using single lever between 1.75 and 4 inches (~4.5 - 10.2 cm), which is more than enough for most users. However, users that prefer very low cutting heights during very intensive grass growth may find 1.75 inches (~4.5 cm) somewhat too high.

Earthwise 50520 features a 2-year limited warranty.

Earthwise 50520 Power Cord

Like many similar walk-behind, corded lawn mowers, Earthwise 50520 comes with pig-tail power cord - it is up to the user to find/buy a proper extension cord for the Earthwise 50520.

Since Earthwise 50520 is rated at 12 Amps, it is highly recommended to buy a somewhat over-dimensioned power cord, in order to reduce energy losses, for example, extension cord rated at 15 Amps.

Note: too thick power cord is harder to work with, harder to pull behind and similar - don't go for too thick cables, either.

The extension cord must be long enough to ensure easy reach to all parts of the lawn and it must be brightly colored so that it is easily visible, even in tall grass - spinning sharp blade and extension cords are recipe for disaster!


Long Story Short: Earthwise 50520 is a strong, sturdy, and reliable lawn mower, that comes at an acceptable price. Since it features a steel deck, it is acceptably lightweight and thanks to properly dimensioned wheels, it is rather maneuverable lawn mower.
