The switch is mounted under the steering column, kind of down under everything. Just to the left of your right foot as you are sitting on the tractor. It's mounted to a bracket, the bracket held on by a 12mm hex head bolt. Remove the bolt, then pull the bracket out, loosen the switch's jam nut, and adjust it so that the switch goes further into the bracket. Reassemble and test. Sometimes a couple tries are required to get it where it needs to be.
