Where WORX Fits Your Lawn
WORX covers small to medium yards with its cordless lineup. You get 14-inch dethatchers, 16-inch and 21-inch push mowers, plus a 20V robotic option. The 16-inch model is self-propelled, while the 21-inch push mower offers smart sensors and a 5.0 Ah battery. The robotic unit automates up to half an acre. You will not find large commercial-grade walk-behind mowers or riding options in this set. The range focuses on residential maintenance rather than heavy-duty turf care. Choose based on whether you need manual push power, self-propelled ease, or full automation.
How to Choose the Right WORX Mower
Match Cutting Width to Yard Size
Select a cutting width that aligns with your lawn dimensions to balance efficiency and maneuverability. The 21-inch model covers half an acre quickly, making it ideal for medium yards. For smaller spaces or tight paths, the 16-inch or 14-inch options provide better handling. A wider deck reduces mowing time but may struggle in confined areas. Check the cutting width spec to ensure the mower fits your available space and meets your coverage needs without excessive passes.
Check Voltage for Power Output
Voltage indicates the power level of the motor, affecting cutting performance under load. The 40V models, including the 21-inch push mower and 16-inch self-propelled unit, deliver robust power for thicker grass. The 20V robotic mower offers lower voltage suited for automated, frequent trimming tasks. Higher voltage generally supports heavier-duty cutting. Ensure your chosen voltage matches your grass conditions and yard size for consistent performance without stalling or bogging down during use.
Evaluate Battery Capacity for Runtime
Battery capacity, measured in Amp-hours (Ah), determines how long the mower runs on a single charge. The 21-inch model includes a 5.0 Ah battery, supporting longer sessions on medium-sized lawns. The 16-inch and 14-inch models use 4.0 Ah batteries, suitable for smaller areas. If you already own WORX 40V tools, sharing batteries can reduce costs and simplify storage. Verify the Ah rating to ensure the runtime meets your lawn’s size without mid-task interruptions.
Choose Drive Type for Ease of Use
Drive type affects how much effort you exert while mowing. The 16-inch model is self-propelled, meaning it moves forward on its own, reducing physical strain on slopes or larger yards. The 21-inch and 14-inch models are push mowers, requiring you to provide the forward motion. Self-propelled units are heavier but easier to maneuver. Decide based on your physical comfort and yard terrain to ensure a comfortable mowing experience.
Select Mowing Functions for Debris Handling
Mowing functions determine how clippings are managed. The 21-inch model offers 3-in-1 capabilities: mulching, bagging, and side discharge, providing flexibility for different lawn care goals. The 16-inch model supports mulching and bagging. The 14-inch dethatcher focuses on thatch removal with 2-in-1 functions. Choose based on whether you prefer to recycle clippings, collect them for cleanup, or discharge them to the side. This spec directly impacts your post-mowing maintenance routine.
