(1) - Worx NITRO™ 40V Cordless Attachment-Capable Driveshare 15" String Trimmer

Drive Share  is the WORX classification for a grass trimmer that offers a split-shaft design to accommodate various attachments, including a Hedge Trimmer, Brush Cutter, Pole Saw, and Edger.

The WG186 works with various attachments available from WORX, sold separately: WA0220 – Hedge Trimmer, WA0221 – Brush Cutter, WA0222 – Pole Saw, WA0223 – Edger. The WG186 and attachments are also compatible with other attachment-capable systems from other brands, including Ryobi®, Craftsman®, Troy-Bilt®, and TrimmerPlus®.

In addition to being attachment-capable, the Worx NITRO™ WG186 offers gas-like performance with a brushless motor and high-capacity batteries. The easy-load head with 0.095in. The dual-exit trimmer line also provides a true professional-grade user experience.

Although the Worx Power Share™ PRO high-capacity batteries come standard with Worx NITRO™ products, they can also be utilized on the traditional Worx products to achieve longer runtime.

Worx recommends that Power Share™ PRO batteries be used with Worx NITRO™ products to unlock optimal performance.

No. The Worx Power Share™ PRO batteries can be used on all existing Worx 20V MAX chargers (WA3742, WA3881, WA3764, WA3770, WA3884, WA3835).

No. The batteries require the same amount of charge-time as the standard Worx Power Share™ batteries. However, due to the Cell-Cooling Technology in the Power Share™ PRO batteries, they stay cooler, longer. As a result, less wait-time is needed before a battery can start charging, due to high temperature.

The WG186 utilizes an easy-load spool head (WA0045) that is new to the Worx product offering. This spool head must be installed onto the head of the grass trimmer prior to loading it with trimmer line. See product manual for trimmer line installation instructions.​

Since the spool head cannot be pre-wound with trimmer line, the WA0045 replacement spool head is sold without trimmer line.
