できるように構成したことを特徴とする刈払機。 At least, in a brush cutter that is equipped with a cutting blade unit at one end of the main operating rod, and is configured such that the intersection angle between the axis of the main operating rod and the rotation center line of the cutting blade can be selected,
A hydraulic cylinder that determines the working angle of the cutting blade unit,
A drive pump for the hydraulic cylinder is arranged near a support point of the main operating rod, and an oil pipe communicates between the hydraulic cylinder and the drive pump, and an end of the drive rod of the hydraulic cylinder is connected to the cutting blade unit. The brush cutter is configured such that the drive pump is operated by an operating handle, and the working angle of the cutting blade can be arbitrarily selected by supplying pressure oil to a hydraulic cylinder through an oil pipe. .
