Many think these are common sense, but you would be surprise how many are over looked. If you have been operating your tractor for the past year without stopping to think about any of these items. Perhaps you could just take a moment and do a refresher of the owners manual. It may surprise you on how complacent you have become. Which I believe is a main factor in accidents. Very rarly is it the newbe that gets hurt or killed, its the "experienced" operator.
