DEWALT DCM561PBS 18v Brushless String Trimmer BODY ONLY

A strimmer or a brushcutter can prove extremely versatile; while they’re ideal for tidying up around the edges of lawns, they can also be used for intensive operations like clearing dense shrub.

When choosing a Strimmer or Brushcutter, there are a number of things to think about. For comfort when using the tool, selecting the right length of shaft for your height is important, as is considering the overall weight of the tool. You may also want to decide whether you want a battery-powered or fuel-driven machine; battery-powered Strimmers don’t need to be refuelled, but can be more powerful than electric models. For home users with relatively small gardens, a corded tool, which you plug into mains power, offers an additional alternative.

Brushed motors use carbon brushes to transfer power from the fixed part of the motor to the rotor. This creates a reliable and relatively inexpensive motor, but brushed motors d require regular maintenance, in order to either clean the brushes or replace them as they wear out. A brushless motor, by contrast, uses a magnet mounted on the rotor to generate the power and electrical switching to perform the function carried out by the brushes. The additional complexity of the motor’s working means that brushless motors are usually more expensive than brushed.

However, eliminating the brushes also eliminates internal friction and maintenance, meaning that brushless motors offer both increased power and a longer working life. Brushless motors also generate less heat and noise and so, on balance, are considered superior to brushed motors.
