I don't know if this qualifies as a tool but it's going to be very useful to me, My shop has a bit of a slope leading up to it. A car that is running can just drive in but most of the cars that come in can't do it under their own power so I tow them up with the lawn tractor but have to stop 10-15 ft. away, then hook up tow straps and pull the car in with a come-along. A long and tiresome job, so I picked up a 12v 3,500 lb winch, built a base for it, hook it up to a battery, hook the battery charger up to it and turn it to Start. Lots of juice flowing and pull the car into the garage in seconds. I love it! Less work for my old back.
