I like some of the ideas that were mentioned in another post on ways to secure equipment. It seems a lot of people use hidden kill switches on some equipment. I have a tractor that is very exposed all summer long in our bulk yard. I always worry about it. I try to keep it parked behind one of the piles so it isn't really visible from the road and never keep the key on it, but its a tractor - not exactly theft proof. Where would I put a kill switch (not physical location mind you - that'll be a secret!) but what do you wire it to?
