Went to clean up back garage a little,needed to put some 2x4 s in the attic . So I piled the wood on my farm tractor climbed up on top & started throwing them up into attic ! Everthing went well til my knee gave out sending me backwards ! While falling backwards some 2x4 s started coming down right at me ! Knocking me off the tractor to a 6 foot fall head 1st on to the concrete !! Well I woke up to the dog licking the blood off my face & 3 missing teeth & this hugh swelling face & head !!! Sore arm & leg but nothing broke thank God but boy do I hurt now !!! The dentist bills is not going to be much of a Christmas present either !!!! So learn from my mistake !!!! Please when you need a ladder go get a ladder !!!!
