At least there we no apparent injuries; the situation could have been much worse.
This incident should remind us all to check our homeowners insurance policies to see what is and isn't covered by the policy as it relates to the tractor. I know that my policy covers property damages on another person's property caused by the tractor, but not any damage to the tractor itself. I could pay for coverage of the tractor, but it is ridiculously expensive. Nor does my policy cover medical if someone else other than an immediate family member (those living in the household) is injured while operating my machine off my property. Thus, I never let others "borrow" my tractor. There are plenty of places to rent similar equipment.
