Who it fits

Key specs for this mower

Voltage: 40V

This rating indicates the electrical system's power level. A 40V setup typically offers more torque than 20V models, allowing the blade to maintain speed in thick grass. You get consistent cutting performance without the power drop-off common in lower-voltage units. This spec helps you compare raw power across different brands and ensures the mower can handle moderate resistance.

Motor Type: Brushless

Brushless motors eliminate carbon brushes, which reduces friction and wear. This design extends the motor's lifespan and improves energy efficiency. You benefit from longer run times per charge and lower maintenance needs over the years. When shopping, choose this over brushed models for better durability and consistent power delivery as the battery drains.

Cutting Width: 17 in

This measurement defines how much grass the blade cuts in a single pass. A 17-inch width strikes a balance between speed and maneuverability. It is wide enough to clear small to midsize yards efficiently but narrow enough to navigate around garden beds and tight corners. Compare this with wider 20-inch models if you prioritize speed over precision.

Battery Capacity: 4.0Ah

Amp-hour (Ah) ratings show how much energy the battery stores. Two 4.0Ah batteries provide sufficient charge for mowing up to a quarter acre. Higher Ah values generally mean longer runtime before you need to recharge. This spec helps you estimate coverage area and plan for larger yards by determining if you need spare batteries for extended sessions.

Design and Build Analysis

According to the listing, the WORX WG745 features a black and orange finish. The deck utilizes a slim design to enable cut-to-edge performance. This layout allows you to mow closer to fences and flower beds without missing strips. The compact form factor is practical for navigating tight spaces in smaller yards.

The mower weighs 39.7 pounds when fully assembled. This light weight contributes to improved maneuverability, making it easier for you to push and turn the machine. The overall dimensions measure 61.8 inches in length, 42.2 inches in width, and 18.1 inches in height. These measurements confirm its classification as a compact unit suitable for storage in tight garages or sheds.

Controls are integrated into the handle and battery system. An on-board battery display lets you monitor charge status without guessing. The 2-in-1 function allows you to switch between mulching and rear-bag discharge. This dual capability means you can choose to recycle clippings into the lawn or collect them for disposal, depending on your preference and local regulations. The build supports efficient operation in yards up to a quarter acre.

Setup And Daily Operation

The WORX WG745 arrives fully assembled, which removes the need for tools or complex setup steps. You simply attach the handle and secure the rear bag or mulch plug, depending on your chosen mowing function. The unit includes two 20V 4.0Ah batteries that combine to form the 40V system. You insert these into the onboard slots and check the battery charge indicator to confirm power levels before starting.

Daily operation centers on the brushless motor, which the listing claims delivers higher cutting power and longer runtime than previous generations. You adjust the cutting height across six positions using a single lever. The 17-inch cutting width is manageable for small yards, and the 40-pound weight aids in pushing the mower over grass. Intellicut technology automatically adjusts the blade speed based on grass density, helping to maintain consistent performance without manual input.

You can switch between mulching and bagging modes to manage clippings. The slim deck design allows you to trim close to obstacles like fences and flower beds, reducing the need for a separate edger. The cordless nature eliminates extension cords, offering freedom of movement. Noise levels are lower than gas models, and there are no emissions or oil changes required. The compact dimensions fit easily into standard garages for storage after use.

Before You Buy This Mower

You should verify that your existing 20V WORX batteries are compatible with this 40V system. The listing specifies two 4.0Ah batteries are included, but you may need additional packs for larger areas. Check your storage space, as the unit measures 61.8 inches long. This model is designed for yards up to a quarter acre. If your lawn is larger, you might need a wider deck or extra battery capacity. Routine upkeep involves cleaning the deck after use to prevent grass buildup. Keep the brushless motor vents clear for longevity. This mower fits into the mid-range of cordless options. It offers a balance of power and portability. You get cut-to-edge capability and IntelliCut technology. These features help maintain consistent performance. Consider this if you want a compact machine that handles mulching and bagging. It suits those who value easy maneuverability and zero emissions. Ensure your local regulations allow electric mowers in your area.

Check before you buy

• Confirm battery compatibility with your existing WORX 20V tools.
• Measure your storage area for the 61.8-inch length.
• Check if your yard size exceeds the quarter-acre limit.
• Verify local noise ordinances for electric mower usage.
