i doubt it....weve bailed many odd things that shouldnt been bailed....one year a guy running a tractor bailed a fawn....or maybe ran it over then cut it with the cutters then bailed it later....i cant remember.....but it went through atleast 1 machine if not 2.....and they were fine.....they shouldnt penetrate a tractor tire.....and probably went into the ground.....i doubt any harm will be done....
