Hi guys,i found the problem with not being able to stop the engine-there is a seperate push button STOP switch,so you turn the key to "off"and then push the button.the pto switch works,the "off the seat"switch works as does the clutch switch.strange thing-when the motor is going and the pto(blades)are turning,when you select revers gear the engine stops.there is a switch at the reverse selector so i might make this into a reverse beeper.any way here are some pics if they work...ken
