i just got a new Hustler Fastrack super duty 42" last month. it had been starting fine until at about 8 hours i shut it off and went to turn it on again and the battery was completely dead. I called the dealer and they said that sometimes when the mower sits in the show room for so long the battery might need charged. so i charged it and it was working fine. I was using it the other day and it had about 10 hours on it and i shut it off and went to turn it back on and it was completely dead. I had to jump it with my other mower and take it home(i was in the neighborhood) I called the dealer and they said they will pick it up on monday. they said i can have a loaner and i will need a mower so i will ask for a loaner(the loaner is a 60"Hustler that goes 15mph!!!, mine goes 8!!!) what do you think is wrong with it???
