I have a LA145 John Deere. It is 1 1/2 years old with 47 hrs. It won't start unless I jump. I've let it run for 45 minutes and then go to start, it begins to crank and thne nothing. No sound at all. Fuse is fine. New battery only after 1 1/2 years? Or could it be something else? I will charge battery today and then go from there.
