I am in security/burglar alarm business. Often need to protect big objects in harsh enviroments, like outdoors. If you are handy with elec. look for something called a magnetic pull apart. It is basically a plastic socket with internal magnet and a plug with built in switch and 2 or 3 ft cord. With plug in socket the switch is closed and when unplugged or the wire is cut the switch/circuit is open. You don't need an alarm. You can use tractor power thru the switch to drive a low current relay which can drive high power -110volt stuff. Think about how the a'cond works except the thermostat is the plug in switch and wire. Even works if they disconnect the battery to steal it.
