Hello all, new to this forum but have been an occasional lurker. We have a Z915b that's about 5-6 years old we use on our Texas ranch. Like many here we've had problems with it not wanting to start intermittently and without warning. Last time it seemed to be the well known PTO switch issue and swapping it out remedied the problem.
When we went to use it for the first time this season on Monday it started right up (I start it weekly over the winter months and run it for about 20 minutes) and we moved it about 6 feet and shut it off. Tightened up the sun canopy and gassed it up, went to start it and begin mowing and nothing. The hour meter would come on, you could here a click at the starter solenoid, and (this is new for us) there was a buzzing sound coming from the two starter relays inside the instrument dashboard. I swapped out the PTO switch and parking brake switch to no avail. Thought it could be the ignition switch or battery. Bottom line, it was the battery- installed a fresh one and all was back to normal. Appreciate everyone's input's on this site, very helpful for figuring out problems that these JD mowers are prone too.
