I have 2 peerless mst 206s that I’m swapping with each other in separate mowers. The problem I’m having is the shift lever height is not the same on them. One sits flush with the case and the other extends up 3 to 4 inches. I removed both levers from their shafts to see if the high one was some sort of removable extension but can’t really tell. Does anyone know if it is removable or part of the shift input shaft?
