    This mower is my homeowner model I had before we started our lco. We ocassionally use it when we get behind or have extra help. Yesterday, it wouldn't start. I checked all the safties. Brake, levers, pto, and seat. The mower just clicks. Any ideas on what to check next?:confused:

    A good place to start is with a voltmeter and a helper. Put the meter in DCVolt mode, black lead on the battery _post_, not on a ground point of any kind, and put the red lead on the positive battery _post_, not on the battery connector. The reason for these specific procedures is to check the battery itself under starting conditions. While holding the volt meter test leads on the battery, have your helper engage the starter. If your battery voltage drops below 10Vdc or so, then you know where to begin. Charge or replace battery. If the battery voltage does not change at all, then you are not loading the battery and you need to check to see where your start circuit is failing. Hope this helps.

    not likely, but make sure the engine isnt locked up..remove spark plug and see if it will spin by hand. ive seen engine that sat for a while had fuel leak past the needle and fill a cylinder.

    The mower just clicks? Clicks as in click, click, click, etc. in a series or just one click when you turn the key? Sounds like the battery is a good place to start.

    Using a volt meter you can place red lead to starter side of solenoid and black lead to a known ground.Have a helper trun key to start position and check voltage. If you don't get 12 volts or more then you could have burnt contact inside solenoid since you say it is clicking. Check that and post back.
