Greenworks vs Westinghouse Mower Specs
power source
The Greenworks 40V 16-Inch Push Lawn Mower runs on a 40V cordless battery system with a 4.0 Ah capacity. This setup offers mobility without cords, though runtime depends on grass conditions. The Westinghouse 13-Inch Electric Dethatcher and Scarifier uses a 12 Amp corded electric motor. It plugs directly into a standard outlet, providing consistent power without battery management. The Greenworks is better for general lawn mowing where cordless freedom matters. The Westinghouse is a specialized tool that requires a nearby outlet, limiting its range to areas within cord reach.
cutting width
The Greenworks mower features a 16-inch cutting width, which allows you to cover more ground per pass when cutting grass. The Westinghouse dethatcher has a narrower 13-inch working width. This narrower path is designed for maneuvering around tight corners, garden beds, and trees rather than wide-open lawn coverage. For standard lawn maintenance, the wider 16-inch deck on the Greenworks is more efficient. The Westinghouse width is sufficient for precise dethatching but covers less area per stroke.
drive type
The Greenworks unit is a push mower, meaning you must provide the forward motion to cut the grass. It relies on your effort to move the 37.5-pound machine across the lawn. The Westinghouse dethatcher is also a push-style tool, weighing just 22.9 pounds. While both require manual pushing, the Westinghouse is significantly lighter due to its construction and lack of a heavy battery. The Greenworks offers a dedicated mowing function, while the Westinghouse is a maintenance tool. Neither offers self-propulsion, so effort is required for both.
mowing function
The Greenworks 40V mower includes a 2-in-1 system that supports both mulching and rear bagging. You can choose to leave clippings on the lawn or collect them in a bag. The Westinghouse unit is a dethatcher and scarifier with a collection bag for debris. It is not designed for cutting grass but for removing thatch and aerating soil. The Greenworks is the clear choice for actual lawn mowing. The Westinghouse serves a different maintenance purpose entirely, focusing on soil health rather than grass height.
weight
The Greenworks mower weighs 37.5 pounds, which includes the battery and charger in the package. It is noted to be 35% lighter than steel deck mowers. The Westinghouse dethatcher weighs only 22.9 pounds, making it much easier to lift, store, and maneuver. The lower weight of the Westinghouse reduces fatigue when pushing the unit around tight spaces or storing it in a shed. For pure ease of handling, the lighter Westinghouse unit has the advantage.
Greenworks or Westinghouse: Which fits your needs
Homeowners with small to medium lawns up to 1/3 acre
The Greenworks 40V mower offers a 16-inch cutting width and 4.0 Ah battery for efficient grass cutting. Its push design and 35% lighter weight compared to steel decks make maneuvering easier.

Users needing to remove thatch and aerate compacted soil
The Westinghouse unit is a dethatcher and scarifier, not a grass mower. It features two heads to rake debris and slice soil channels. The 13-inch path and 12-amp motor provide power without battery runtime limits. At just 22.9 pounds, it is lightweight and easy to store. The 8-gallon bag captures waste for quick cleanup.
Buyers wanting cordless freedom and battery compatibility with other tools
You can use the 40V battery with over 75 Greenworks tools like trimmers and blowers. This compatibility expands your cordless toolkit without buying separate power sources. The mower runs on a 40V cordless battery, offering mobility without cords. The 4.0 Ah capacity supports cutting up to a third of an acre on a single charge.
