The best machines for the clearance of large areas of scrub, undergrowth or grass, the straight shaft of a brush cutter permits the use of a metal blade, enabling the brush cutter to cut through mature undergrowth and woody vegetation, impossible to clear with a nylon line alone. The type of work you need to complete will determine the style of handlebars that you choose. The loop-handle style machine will give you great control for spot clearance work or where you will be working in a tight space. However, the wide-grip or bicycle-style handlebars are much better for the mowing of large open areas where a side-to-side scything motion is achievable, thus speeding up the clearance process. Most brush cutters are supplied with either a single shoulder strap or a full body harness to take the strain out of your work.
