The WORX WG743 40V 17-Inch Cordless Lawn Mower is a battery-powered push mower designed for homeowners who want the convenience of cordless mowing without the maintenance, fuel, and exhaust associated with a traditional gas mower. Powered by two 20V 4.0Ah WORX Power Share batteries, the WG743 delivers a combined 40V system and adds useful features such as IntelliCut technology, seven cutting-height positions, 2-in-1 bagging and mulching, and a cut-to-edge design.
The mower is particularly appealing for small to medium-sized lawns, where its 17-inch deck provides a good balance between maneuverability and cutting coverage. Independent testing has also found the mower easy to set up and effective on small-to-medium lawns, while highlighting its relatively compact cutting width as an advantage for maneuverability.

WORX WG743 40V Lawn Mower At A Glance
The WG743 is a conventional push mower rather than a self-propelled model. Its lightweight design, cordless operation, and Power Share battery compatibility make it a practical option for homeowners who already own other WORX tools.
Key specifications include:
- 40V maximum power from two 20V batteries
- 17-inch deck width
- 16-inch cutting diameter
- Seven cutting-height positions
- 1.5- to 3.5-inch cutting height on the current U.S. specification
- 1.1-bushel grass collection bag
- Two 20V 4.0Ah batteries included
- Dual-port battery charger
- 2-in-1 bagging and mulching
- IntelliCut torque management
- Cut-to-edge design
- Fully collapsible handle
- 5-year warranty on the current WORX U.S. listing
One important detail is that specifications can vary between regional versions and model revisions. Earlier WG743 documentation lists a 1.5- to 4-inch cutting range, 45-liter collection capacity, and approximately 35.3-pound weight, while the current U.S. product page lists 1.5-3.5 inches and 38.1 pounds. Buyers should therefore verify the specification for the exact WG743 version being purchased.
Two 20V Batteries Provide 40V Power
The defining feature of the WORX WG743 is its dual-battery configuration.
Rather than using one large proprietary 40V battery, the mower uses two 20V Power Share batteries simultaneously. The current package includes two 4.0Ah batteries and a dual-port charger.
This approach has an important advantage for existing WORX customers. The same Power Share battery platform can be used across a large range of compatible WORX tools. WORX states that its Power Share system works across 75+ 20V, 40V, and 80V tools.
However, the WG743 is designed to operate with both batteries installed. It cannot simply be operated with one battery when less power is needed. WORX recommends using two batteries with matching amp-hour ratings for proper operation.
IntelliCut Technology Helps Manage Power
One of the most useful features is IntelliCut technology.
The system allows the mower to increase torque when it encounters thicker or denser grass and reduce the power demand when conditions are easier. This is designed to provide additional cutting power when needed while conserving battery energy during lighter mowing.
For homeowners, this is more useful than simply having a fixed high-power setting. A lawn can contain different grass densities, and the ability to adjust power according to conditions can help balance cutting performance and battery efficiency.
17-Inch Deck for Small and Medium Lawns
The WG743’s 17-inch deck and approximately 16-inch cutting diameter place it firmly in the compact-to-mid-size cordless mower category.
A 17-inch mower will not cover as much ground per pass as a 21-inch mower, but the narrower deck provides several benefits.
It can be easier to maneuver around:
- Trees
- Flower beds
- Garden borders
- Narrow passages
- Fences
- Landscaping features
- Smaller yards
Independent testing has described the WG743 as particularly suitable for small-to-medium lawns, with its compact design making it easy to handle.
For a large open property, however, the smaller deck means more passes and potentially more mowing time.
Cut-to-Edge Design
The cut-to-edge design is another practical feature.
WORX positions the blade closer to the side of the mower so that users can mow closer to fences, patios, landscaping, and other lawn boundaries. The objective is to leave less uncut grass along edges that would otherwise require a string trimmer.
It does not eliminate the need for trimming in every situation, but it can reduce the amount of finishing work required after mowing.
Seven-Position Cutting Height Adjustment
The WG743 uses a single-lever height adjustment system, making it relatively straightforward to change the cutting height.
The current U.S. specifications list seven positions between approximately 1.5 and 3.5 inches.
This flexibility allows homeowners to adapt the mower to different lawn conditions and preferences.
For example, a higher setting can be useful when grass is longer or during periods of heat or drought, while a lower setting can produce a shorter finished appearance when lawn conditions allow it.
2-in-1 Bagging and Mulching
The WORX WG743 provides two primary ways to manage grass clippings: bagging and mulching.
When bagging, the mower collects clippings in its grass catcher. The current U.S. model is listed with a 1.1-bushel collection bag and a full-bag indicator.
Mulching provides another option. Instead of collecting the grass, the mower processes the clippings and returns them to the lawn.
For homeowners who prefer not to empty a grass bag repeatedly, mulching can be convenient when lawn conditions are appropriate.
Is The WORX WG743 Self-Propelled?
No. The WG743 is not self-propelled.
WORX specifically identifies it as a push mower.
This is an important consideration for anyone with a sloped or particularly large yard. On relatively flat lawns, the mower’s cordless design and manageable size can make pushing straightforward. On steep terrain, however, a self-propelled mower may be more convenient.
The absence of self-propulsion also means the battery does not have to power a drive system, allowing the motor’s energy to focus on cutting.
How Heavy Is The WORX WG743?
Weight information varies by version and documentation.
The current WORX U.S. product page lists the machine at 38.1 pounds, while earlier WG743 documentation lists approximately 35.3 pounds.
Either way, the WG743 is designed around a relatively manageable cordless-mower format rather than the heavier construction of many large gas-powered machines.
Its lightweight construction contributes to maneuverability, particularly when turning around landscaping or navigating smaller spaces.
Plastic Deck: Advantage or Disadvantage?
The WG743 uses a durable lightweight plastic deck rather than a traditional steel deck. WORX describes this construction as helping make the mower lighter and more maneuverable.
There is a clear trade-off.
A plastic deck can reduce overall weight and make the mower easier to push and handle. On the other hand, homeowners who prefer the feel and perceived ruggedness of a heavy steel deck may prefer a different mower.
For typical residential mowing, the lightweight construction is one of the WG743’s most practical characteristics.
Battery Charging and Runtime Considerations
The WG743 comes with two 4.0Ah batteries and a dual-port charger. WORX says the dual charger can charge both batteries efficiently.
Earlier technical documentation indicates that charging two 4.0Ah batteries can take approximately two hours, depending on the charger and specific battery configuration.
Actual mowing runtime depends heavily on conditions. Grass height, grass density, cutting height, moisture, mowing speed, and how frequently IntelliCut needs to increase torque can all affect battery consumption.
This is why the WG743 is better suited to small and medium lawns than very large properties requiring long continuous mowing sessions.
Noise and Maintenance
One major advantage of a battery-powered mower is the absence of gasoline-engine maintenance.
There is no need for:
- Gasoline
- Engine oil
- Spark plugs
- Carburetor maintenance
- Fuel stabilizer
- Engine exhaust
The WG743 is also substantially quieter in operation than a conventional gas mower. Technical documentation for a related WG743 regional version lists approximately 89.3 dB(A) sound power.
Battery power does not mean maintenance-free operation, however. The blade still needs inspection and sharpening or replacement when appropriate, and the underside should be kept clear of accumulated grass.

Who Should Buy The WORX WG743?
The WORX WG743 is best suited to homeowners with small to medium-sized yards who prioritize convenience and low maintenance.
It is particularly attractive if the buyer already owns WORX Power Share tools because the included batteries can potentially be used with other compatible equipment.
The mower is also a good candidate for people who want to eliminate gasoline from their lawn-care routine without moving to an expensive commercial-grade battery mower.
Who Should Consider A Different Mower?
The WG743 may not be the best option for everyone.
A larger lawn may justify a 21-inch or larger deck to reduce the number of passes. A steep property may be better served by a self-propelled model. Likewise, homeowners who regularly mow very tall, wet, or heavily overgrown grass may want a more powerful mower with a larger battery system.
WORX itself advises against mowing wet grass because wet conditions can reduce cutting performance, create clumps, interfere with mulching, and reduce runtime.
Final Verdict: Is The WORX WG743 Worth It?
The WORX WG743 40V 17-Inch Cordless Lawn Mower is a practical choice for homeowners who want a relatively compact, easy-to-use battery mower without the hassles of gasoline-powered equipment.
Its strongest features are the dual 20V 4.0Ah battery system, IntelliCut technology, seven-position height adjustment, cut-to-edge design, and 2-in-1 bagging/mulching capability. The ability to use the same Power Share batteries across compatible WORX tools further increases its value for existing WORX users.
The main limitations are equally clear: it is not self-propelled, the 17-inch deck is better suited to smaller properties, and battery runtime can vary considerably with mowing conditions.
Overall, the WG743 makes the most sense for homeowners who have a small-to-medium lawn and want a lightweight, cordless mower that is simple to operate and maintain. For that type of yard, it provides a compelling combination of convenience, cutting flexibility, and battery compatibility.
