Abstract: A vegetation cutter comprises a frame rod having a front end portion and a rear end portion, and assuming a hollow tube having an open front end; a cutter head mounted on the front end portion of the frame rod and including a drive motor, a cooling fan to be rotated by the drive motor, and a rotary cutter to be rotated by the drive motor; and a power head mounted on the rear end portion of the frame rod and providing electric power for the drive motor. The frame rod is provided with an air intake aperture located at a position rearward than the cutter head and communicating through the hollow tube toward the cutter head. The frame rod is comprised of a front part rod and a rear part rod separably coupled together by means of a tubular joint. The air intake aperture is located on the front part rod.

Abstract: A vegetation cutter comprises: a frame rod having a longitudinal axis and a front end; a rotary cutter mounted on the front end of the frame rod; a drive motor for driving the rotary cutter; a grip disposed around the frame rod and having an external surface to be held by a user; a power switch trigger arranged on the grip for energizing the drive motor; and a safety lock mechanism for rendering the power switch trigger inoperative when the safety lock mechanism is in a lock position and for rendering the power switch trigger operative when the safety lock mechanism is in a release position. The safety lock mechanism includes a manipulating knob for selectively setting the safety lock mechanism in the lock position and in the release position. The manipulating knob is disposed on the grip at a position circumferentially opposite to the power switch trigger and is turnable around an axis which is parallel to the longitudinal axis of the frame rod to selectively bring the safety lock mechanism to the lock position and the release position.
