ABSTRACT:
A programmed steering and cutting blade control apparatus for self-contained lawn mowers with a nylon tape having rectangular members disposed on the upper and lower surfaces of the nylon tape which extends between two reels where the rectangular members actuate micro switches disposed below the nylon tape and actuate micro switches disposed above the nylon tape where such upper micro switches are connected to a plate which is reversible so as in one instance to reverse the plate and the micro switches are disposed away from the nylon tape and not actuated. Two lower micro switches actuate a turning wheel motor and a third micro switch actuates a brake. The upper micro switch actuates the cutting blades. The movement of the programmed nylon tape is synchronized with the movement of the drive wheels to ensure the self-contained lawn mower moves along the preplanned route.
