Buying Tips for DeWalt Brushless String Trimmers

Before choosing which dewalt string trimmer to buy, determine whether a bare tool or a complete combo kit suits your needs. If you already own DeWalt 20V MAX batteries and chargers, purchasing a bare tool avoids redundant equipment. If you need dedicated batteries for outdoor tasks, a bundle with an included 4.0 Ah battery provides reliable runtime out of the box.

Consider cutting swath and line thickness relative to your property size. A broad 16-inch or 17-inch cutting path clears expansive yards quickly, though it increases tool weight and battery consumption. Compact 12-inch trimmers maneuver easily around garden borders and patio furniture. For standard grass, 0.080-inch line performs well, while dense weeds benefit from thicker 0.095-inch line.

Lastly, evaluate tool weight and ergonomic features. Models weighing under six pounds with telescoping shafts or support wheels significantly reduce arm and back strain. For properties with tight storage, trimmers with folding hinges allow compact storage in garages, sheds, or vehicle trunks.

FAQ

Can you use a DeWalt 20V MAX battery on a 60V MAX string trimmer?

No, standard DeWalt 20V MAX batteries cannot power a 60V MAX trimmer like the DCST972BR. The 60V MAX platform requires DeWalt FLEXVOLT batteries, which provide the higher operating voltage needed for high-demand powerheads.

What is the benefit of a brushless motor on a string trimmer?

Brushless motors use electronic microprocessors rather than carbon brushes to transfer power. This design generates less friction and heat, resulting in longer battery runtime, extended motor life, and steady torque through thick grass.

How do bump feed heads differ from automatic line feed systems?

A bump feed head releases additional trimmer line when you tap the base against the ground while spinning. Automatic feed systems advance line when the motor starts or through centrifugal sensors, eliminating the need to tap the unit.

What does bare tool mean when buying a trimmer?

A bare tool listing includes the trimmer, safety guard, and basic accessories, but does not come with a battery or charger. It is meant for users who already own compatible batteries within that tool platform.

How does a folding shaft trimmer help with storage?

A folding shaft trimmer features a central hinge that folds the shaft in half. This reduces the tool’s length by 40 percent or more, allowing convenient storage in compact sheds, closets, or car trunks without disassembly.
