Operating Techniques - Metal or Plastic Blade
Brushcutter blades may be used to cut and trim a wide variety of materials.
Refer to the blade selection section for determining the correct blade for the
application.
Scything (3-, 8-, and 80-tooth weed/grass, and brush blades)
• To cut large sections of field grass and weeds swing the cutting head in a
level arc, gradually feeding the blade into the material being cut. Adjust
throttle speed according to your work.
• Do not swing the main pipe with arms. Turn hips to swing
the blade horizontally from right to left, and cut weeds on the
left side of the blade.
• Do not scythe back and forth as the grass may scatter and
kickback may occur easily.
• Tilt blade left by 5 to 10 degrees so that cut grasses will
push left, making progress easier.
• Move forward with each arc to cut a swath.
• Width of cutting swath depends on arc. Use a larger arc
for a wider swath, or a smaller arc for a narrow swath.
Suggested cutting width is about 1.5 m (4.9 ft).
• When scything large brush up to 12.7 mm (0.5 in.)
diameter from right to left, avoid cutting with highlighted
section.
Reaction Forces
The cutting attachment will continue to rotate even after
the throttle is released, maintain control of the unit until it
has come to a complete stop.
Blade thrust may occur when the spinning blade contacts
an object that it does not immediately cut. Following
proper cutting techniques will prevent blade thrust.
Blade thrust can be violent enough to cause the unit and/or
operator to be propelled in any direction, and possibly lose
control of the unit.
