If you take it other places then yes insurance makes sense. Mine never leaves my house. If my tractor gets flooded I have bigger problems because God is mad and flooded the whole earth again. I can't envision rolling it with the lay of my land. Wind? - maybe a tornado. I will take my chances. A lot of these scenarios may be different for others.
I don't mean this as a brag but I have well over a million dollars of equipment between my personal and my business things. Insurance can be very expensive over the long term. I spend a lot of time evaluating risks and decide what to insure and what to not insure based on the likelihood of something happening. I guess you also have to factor in your ability to replace something without insurance should something happen.
Another way to look at it is insurance companies make a profit. Specifically what they take in in premiums minus what they pay out in claims leaves them with a profit. They also have to pay for overhead, adjusters, salesmen, advertising, etc. In most cases if you can afford it should disaster strike you are better off self insuring.
