push lawn mower

The blade is made from an old push mower scissor action. It 'was an electric motor controlled by chain and sprocket fitted. The radio receiver is a small, cheap RC car from walmart and torn by the Darlington transistor and relay 30A automotive industry has been strengthened. The rear wheels are aligned separately by two electric motors up to 20.01, to generate enough torque to climb a tree to produce electricity. The car tips the scales at 100 pounds. Power is not a problem, pull! Two 12V 17Ah lead acidGel cells in series power this car for over an hour, even with high grass! I would read it and follow a GPS or an array of sensors to adapt to the ground.
