Comparing Worx Mower and Dethatcher Specs
Cutting Width
The WORX 21-Inch 40V Cordless Push Lawn Mower (WG752) features a 21-inch cutting width. This wider deck covers more ground per pass, making it efficient for larger lawns up to half an acre. The WORX 40V 14-Inch Cordless Dethatcher (WG855) has a 14-inch cutting width. This narrower path is designed for targeted thatch removal rather than broad mowing. A wider cutting width generally reduces the time needed to cover a lawn area. You will finish mowing faster with the 21-inch model. The dethatcher is narrower because it focuses on precision work in specific zones. For general lawn maintenance, the mower’s width offers a clear advantage in speed.
Mowing Function
The WG752 mower offers 3-in-1 functionality. You can mulch clippings, bag them, or use the rear side-discharge chute. This versatility allows you to manage grass clippings based on your lawn care preferences. The WG855 dethatcher provides 2-in-1 design options. You can switch between a dethatching reel with 24 metal tines and a scarifier reel with 16 angled blades. These functions remove thatch and promote deeper soil penetration. The mower handles grass cutting and disposal. The dethatcher handles lawn health maintenance. Each tool serves a distinct purpose. The mower is essential for regular cutting. The dethatcher is specialized for seasonal care. Both offer multi-functionality within their specific roles.
Battery Capacity
The WG752 mower includes two 20V 5.0Ah PowerShare Pro batteries. This setup provides a total capacity of 10.0Ah. The included dual charger helps keep power ready. The WG855 dethatcher includes two batteries with a capacity of 4.0Ah each, totaling 8.0Ah. Both tools share the same PowerShare ecosystem, meaning you can swap batteries between them if you own other compatible tools. The mower’s higher total battery capacity supports its motor’s demand for mowing thick grass. The dethatcher’s batteries are engineered to stay cool and resist heat damage. The mower offers slightly more runtime potential due to the larger battery capacity.
Drive Type
The WG752 is a push lawn mower. It requires you to push the unit across the lawn. It features a fully collapsible handle for storage and a single 7-position lever for cutting height adjustments from 1.5 to 4 inches. The WG855 dethatcher is also a push tool. It features larger front wheels that turn easily around rough terrain and small obstacles. The curved deck design minimizes resistance for a smooth pushing experience. The dethatcher offers single-lever depth adjustment with four positions for dethatching and scarifying. Both rely on your physical effort to move them. The dethatcher’s larger wheels may help slightly on uneven ground, but both are manual push tools.
Weight
The WG752 mower weighs 55.6 pounds. This weight includes the deck, motor, batteries, and attachments. The heavier build provides stability during mowing. The WG855 dethatcher weighs 26.2 pounds. This is significantly lighter than the mower. The lighter weight makes it easier to maneuver around obstacles and store. It also reduces fatigue when pushing the tool across the lawn for extended periods. If you have difficulty lifting or pushing heavy equipment, the dethatcher is easier to handle. The mower’s weight is necessary for its larger cutting deck and motor. The dethatcher’s lightness is a practical advantage for ease of use.
