If Digger's solution does not help, then it is inside the switch. You can with care take it apart and clean it also. If the tractor is outside in the rain and elements, then the problem may well be inside the switch. There are sme springs inside so be careful when you open it up. Do get the delectic grease as Digger stated. Use it. Moving the switch to make it start leads me inside and a contact problem. Finally, if all else fails, look up to the top and order one from one of the good sponsors.
