check your battery terminals as well. Mine did the same to me awhile ago, and I had a loose terminal. Then check you range selector were it meets the tractor look for sticks or mud, then check your pedals hst shafts. Tucked up just above the hydralic filter on the left side are two plastic nuts which are tied into the hst safety interlock. if these nuts are loose your tractor won't start. here is a pic. the grey nuts are what you are looking for
