Everyone needs liability insurance whether you use your tractor for home or business. If your driving your tractor and get a bit inattentive and just sort of wipe the side out of your neighbors car which is sitting on the property line while you are watching the boxblade or tiller, you better have liability insurance. If your tractor rolls down the hill and hits your neighbor or his property, you better have liability insurance. I could give a few hundred examples but surely the point is made. Your actions on a tractor or car or whatever can cost you. Most states require car owners/drivers have liability coverage to cover the repairs caused to another person.
If you own a home you should have liability coverage which is covering you or your negligence on that property. It should be contained in the homeowners policy. If you borrow your neighbors tractor and wreck it, your liability coverage should cover it.
You do damage, your liable to pay for or fix the daamage. Has nothing to do with business, it can but not always. You tear it up or lose something loaned to you, your liable.
Everyone should have some type of liability insurance attached to some type of policy or a straight liability insurance policy.
I have a big rock on the hillside of my property. I've started to move it a couple of times and it is shaped to where it wants to roll. It probably weighs 300 to 350 lbs. I've gotten on the lower side of it and tried getting it into my bucket and it trys to get around the edge of the bucket and has scared the **** out of me a couple of times so I had just left it. Every time I drove by it, the thing would whisper, you chicken. I told Roy to move it when he was out doing some work for me on his skid steer. It almost got away from him (40 years experience in excavating business) and he also had a brown spot. He did get it moved but got his attention. If the rock had rolled down the hill and hit my neighbors house, car, truck, garage or neighbor, who would have paid when I was the one doing the moving?
Everyone needs liability insurance to pay for your mistakes or damages that appear to be caused by you.
