ABSTRACT:
Disclosed is a mowing apparatus, which includes a pair of first and second cutting members slidably superposed with each other, each of the members including a plurality of aligned cutting teeth; mechanism for moving the first cutting member relative to the second cutting member reciprocably within a predetermined range in the direction of the aligned cutting teeth at a substantially uniform speed; and a drive source for driving the moving mechanism. The moving mechanism includes a solenoid actuator having first and second coils and a plunger provided reciprocatingly movably between the first and second coils. The plunger is connected to the first cutting member. The moving mechanism further includes a switch alternately switches the first and second coils ON, thereby causing the first and second coils to become magnetized alternately to attract the plunger alternately so that the first cutting member to which the plunger is coupled is moved at a substantially uniform speed in accordance with the motion of the plunger.
