Your info: No Start
Explain what it is doing because no start can and does cover a large number of things that can cause no start. Battery good
How do you know the battery is good? Did you have it tested at an auto parts store or somewhere else that can actually test it, not just see its voltage? One year old
What is one year old? No crank
What does no crank mean to you? What it means to me is you turn the key to the start position and you hear or do not hear a noise and nothing else happens. No starter whirling. Intermittent
What is intermittent? Zero turn
What is the model number of the zero turn? Anyone have a wiring diagram?
I have lots of wiring diagrams but almost all of them would do you no good unless they are for your zero turn.
Battery, battery connections and safety switches (parking brake and drive levers) would get my attention first. Hard to say what your issue is without more info.
