My 1999 335 stopped running after cutting the whole lawn. Checked both plugs and no spark. Also checked fuel flow also. It quit 2 weeks earlier and no spark then. Tested again and had spark, so cut grass.I can't think both coils would go bad at the same time. If anyone has had this problem I would like to hear what was the cause. Thanks very much for your help. Richard

Probably a part of the ignition called an ignitor. This tractor has a very expensive engine to throw parts at and may be cheaper to have the dealer fix it. Roger

Thanks Roger. Without a tech manual it's not worth buying $55 coils with no returns on electrical parts. I can take it in and let the pros get her back to work.

Terry: I am new to posting on the site, so thanks for the help. I'm still interested in any other ideas on the problem. Richard

Pull the top shroud so that you can get to the coils. Our 335 had a problem shutting down, only one side of the engine would quit running when the key was turned to OFF.

A short to ground in the lead to the coils would kill the spark.

Found a broken wire at the push on connector at the left coil.

While you are in there clean the engine cooling fins and if you have not adjusted the valves in the last 300 hours of use do it now.
