Method and apparatus for mowing lawns

摘要: The present invention discloses an unattended lawn mowing system in which multiple solar powered self propelled, random motion mowers are used singly or combination to mow a pre-defined area. zone is defined as region of grass bounded by naturally occurring man made obstacles infinite variation including, but not limited to, high grass, flowers, trees, fences and edging. Each unit powered, self-propelled, mower comprises frame with set drive coaster wheels on the frame. A batteries battery electric motors mounted said output means from power cutting mechanism Photovoltaic panels receive rays convert them into electrical charge for controlling orientation so face direction greatest intensity. actuation controlled monitoring that detects level energy panels. Such modes include starting mower, stopping altering travel re-charging mower. Random accommodated providing contact switches outer periphery changed more than 90 degrees when impact physical barrier surrounding within area be cut. further includes switch constructed cells connected manner allows automatic switching between optimum use re-charging.
