Accidents can happen to anyone at anytime without warning. Farming which includes the operation of machinery is dangerous and nothing should be taken for granted. Murphy's Law strikes again! How dare that tree jump out like that and hit the tractor, maybe Mr. Tree should meet Mister Chain Saw. Had the sun shade been made of steel, there could have been more damage to the tractor, chalk one up for plastic. Happy there were no injuries and making humor of the event is good, very good and the driver deserves credit for stopping when she did. Good job, what's next?
