JOhn Deere 425 won't even crank
My JD 425 was running perfectly. Today it wouldn't start,but had starter clicking noise. Charged battery although it was 75% charged, and it started and ran fine. I shut it off, and now it won't even click. Battery is fully charged, but all I hear when I turn the key is slight hum which sounds like it's coming from the fuse panel. The starter does not click or even try to spin. There is a green LCD light on the panel where the fuses are, and it lights up when key is turned. The time dely thing was rep[laced about a year ago. This is an older model 425 and it has a Kawasaki engine.
Any suggestions greatly appreciated
