WORX 40V Nitro String Trimmer WG186.9 — 15" Driveshare Bare-Tool, Brushless Power

The WORX Nitro WG186.9 is a 40V cordless, driveshare-capable 15" string trimmer built for gas-like cutting performance without fumes or tune-ups.

This Nitro WG186.9 model is a bare-tool, battery-powered string trimmer engineered to deliver commercial-style cutting capability for homeowners who demand cleaner edges and faster clearing. With a split-shaft Driveshare design, it converts into multiple yard tools with compatible attachments (sold separately). It accepts WORX PowerShare Pro batteries for extended runtime and pairs the efficiency of a brushless motor with a 15" dual-exit head for professional-grade trimming tasks.

How powerful is the WG186.9 compared with gas trimmers?

The Nitro line is tuned to give battery users a level of cutting performance and runtime that approaches small gas units, especially when using higher-capacity PowerShare Pro batteries. The brushless motor increases efficiency and torque while reducing maintenance needs.

• 40V platform designed for stronger torque than standard 20V trimmers
• Brushless motor: more efficient, longer life, better power delivery
• Compatible with WA3012 (4.0Ah) and WA3571 (5.0Ah) for extended runtimes
• Cleaner startup and no fuel mixing or spark plug maintenance

What makes the Driveshare system useful for my yard?

Driveshare lets you swap the trimmer shaft for hedge trimmer, edger, pole saw, or brush cutter attachments so one shaft performs many jobs. That saves storage space and reduces the cost of buying separate dedicated machines.

• Split-shaft connection accepts a range of Worx (and many universal) attachments
• One motor/shaft platform replaces multiple single-purpose tools
• Ideal for properties with mixed lawn, edging, and light brush needs
• Attachments sold separately, letting you customize your kit over time

How easy is it to operate and maintain?

The 15" dual-exit cutting head has an easy-load design to minimize downtime changing line, and variable speed control helps balance power and battery life. Because it’s brushless and cordless, routine maintenance is limited compared with gas tools.

• Easy-load trimmer head reduces rethreading effort
• Variable speed with ECO-mode for longer runtime and gentler cutting
• No spark plugs, carburetors, or fuel mixing to manage
• Includes one replacement easy-load trimmer head in the box

What are the cutting specs and what’s included?

The WG186.9 uses 0.095" diameter line with a 20-foot line length specification, matching the line capacity of many commercial-grade trimmers. This unit ships as the bare tool, so batteries and charger must be purchased separately for full operation.

• 15-inch cutting swath with dual-exit cutting head
• Line diameter: 0.095 inches; line length spec up to 20 feet
• Bare tool only — batteries and charger not included
• Universal compatibility with many attachment-capable systems

Who this is for: The WORX Nitro WG186.9 suits homeowners and property stewards who want near-gas performance from a cordless platform and value modularity. Choose this model if you plan to expand into Driveshare attachments, prefer lighter maintenance than gas, and will pair it with PowerShare Pro batteries for the best runtime and power balance.
