I currently own a John Deere LA145 Mower which is practically new only 120 hrs. I went to get on it today to start it up and mow and checked oil and fuel and everything looked good, but it wont turn over. The battery is not dead. I would like to check the Fuel Switch, and Safety Switch? Please let me know where those are located and if you have other ideas for me to check please let me know. Responses ASAP are appreciated as the lawn is getting out of control. Thanks in advance.
