GreenWorks 21302 Features and Specifications

GreenWorks 21302 is a highly maneuverable and energy-autonomous unit, thanks to its cordless design.

With the 2.0 Ah 40V G-MAX lithium battery, GreenWorks 21302 weighs 12.2 pounds (~5.5 kg) and is used with two hands via main handle with its controls and auxiliary assist handle.

Fully charged 2.0 Ah 40V G-MAX lithium battery stores enough energy for approximately 30 minutes of continuous operation.

When the battery is discharged, it takes some 120 minutes (2h) to charge it completely.

Pivoting trimmer head with edging wheel allows the user accurate both trimming and edging.

During operation, unlike gas operated units, GreenWorks 21302 doesn't emit any gases or fumes and is relatively quiet during operation.

The cutting path is 13 inches (~33 cm) with a no-load speed of 8000 rpm. GreenWorks 21302 uses a single 0.065 inch (1.65 mm) monofilament line with automatic line feed.

GreenWorks 21302 comes with a filled spool line. When the spool gets empty, one can replace it with a new pre-wound spool or one can refill the spool with 0.065" (1.65 mm) nylon monofilament line approximately 18 feet (~5.5 m) long manually.

During operation, the cutting line is worn down and it becomes shorter. GreenWorks' Automatic Line Advancement system ensures that the line advances to the correct length as it wears down. If the lines become too short, stop and restart the trimmer - this will automatically lengthen the line by 1/4" (6.4 mm).

GreenWorks G-MAX 40V Lithium-Ion Batteries

GreenWorks 21302 comes with GreenWorks 29462 G-MAX 2.0 Ah 40V lithium-ion battery.

GreenWorks 21302 also support the use of larger GreenWorks 29472 G-MAX 4.0 Ah 40V lithium-ion battery which extends the runtime up to 60 minutes.

Both GreenWorks 29462 and GreenWorks 29472 can be used in any GreenWorks cordless tools that are designed for GreenWorks G-MAX 40 volts lithium ion battery - so, if you already own any of these batteries, getting bare tools can be rather cheap.
