The WORX WG745 is a 40V cordless lawn mower designed for homeowners with small to midsize yards up to 1/4 acre. It combines the convenience of battery power with the performance of a brushless motor, making it a compelling alternative to gas mowers for those who value low maintenance and quiet operation.
Standout features include the brushless motor 2.0, which offers 40% higher cutting power and longer life than previous generations. IntelliCut technology automatically adjusts cutting speed based on grass density, optimizing runtime and ensuring a clean cut even in thick patches. The 2-in-1 system lets you mulch clippings for fertilizer or bag them for a tidy lawn.
Design and build quality are impressive for the price. At only 40 pounds, it is one of the lightest mowers in its class, and the cut-to-edge deck allows you to mow right up to borders. The collapsible handles and vertical storage option are great space savers in small sheds or garages. The single lever height adjustment offers six positions from 1 to 3 inches.
Potential drawbacks include a 17-inch cutting width, which is narrower than many 20-21 inch models, meaning more passes on larger lawns. It is not self-propelled, so you will need to push it yourself. While the included batteries cover 1/4 acre, larger yards may require purchasing an extra battery pack for uninterrupted mowing.
Overall, the WORX WG745 is an excellent choice for homeowners seeking a lightweight, efficient, and easy-to-store cordless mower. It delivers strong performance for small lawns, and the brushless motor ensures years of reliable service. If your yard is under 1/4 acre and you want to ditch gas and cords, this mower is a smart investment.
Pros
- Cord-free convenience with fast push-button start
- Very lightweight and easy to maneuver, especially for a battery mower
- Intellicut helps preserve battery power while maintaining cut quality
- Tool-free height adjustment and compact folding handle for storage
- Quiet operation at 89 dB is pleasant for the user and neighbors
Cons
- Best suited for 1/8 acre or smaller, not large lawns
- 17-inch cutting width means more passes on bigger yards

The WORX WG743 is a 40V cordless walk-behind mower designed for lawns up to 1/8 acre. It comes with two 20V 4.0Ah PowerShare batteries and a dual charger, so you get reliable starting power without the hassle of gas or cords. This lightweight mower is an ideal fit for homeowners with small to medium yards who want a quieter, lower-maintenance alternative to gas equipment.
The standout Intellicut system uses sensors to automatically adjust motor speed based on grass density. It powers up in thick, heavy grass for a clean cut and slows down in lighter conditions to save battery. With a 17-inch deck and a 7-position single-lever height adjustment from 1.5 to 4 inches, the WG743 offers plenty of control for precise mowing in tight spaces.
Weighing about 35 pounds, this mower is noticeably easy to push, lift, and maneuver. The fully collapsible handle makes storage simple, and the integrated carry handle adds portability. The 2-in-1 design includes a 1.2-bushel collection bag with a full-bag indicator and a mulch plug, giving you two practical ways to handle clippings.
The main drawbacks are its limited cutting width and mowing area. The 17-inch deck is smaller than many gas mowers, and the 1/8-acre capacity means larger lawns will need multiple charges or extra batteries. It is also a manual push mower without self-propulsion, so you will need to supply the pushing effort.
For small properties, the WORX WG743 is a smart, dependable choice that combines quiet operation, smart power management, and versatile grass handling. The PowerShare battery system adds long-term value, especially if you already use other WORX tools. If your yard fits the 1/8-acre footprint, this cordless mower is a convenient and capable investment.
