A 3T8730 Protective Cover Assembly is available for all machines equipped with the open ROPS cab and using the 9G7641 Start Switch Group. This cover assembly fits under the switch mounting nut. The cover keeps moisture from entering the switch when the key is removed. This reduces the possibility of the start switch sticking in the "Start" position.
