Abstract

The mower frame is pivot-mounted on two non-driven back-wheels and the fron tpart of the frame is pivot-mounted on the chassis containing the drive mechanism and mower which is adjustable in height. A drive-wheel is coupled to a drive motor through a gear. A sensor is positioned on the front chassis arm. The mower consists of four rotary cogged blades. The electrical motor of the mower is fed from an accumulator. The regulator consists of a servo motor altering the steering direction of at least one of the wheels; a sensor; and an electrical control switch controlled by the output signal of the sensor. The sensor contains a vertical ferrite rod and a coil coaxial to it. The control switch contains a comparator circuit.
