We have a Cub Cadet Model 2176 lawn tractor. The pto connector has broken "teeth" and loose wires. This is the part that the main wiring goes into, then it gets plugged into the pto switch, which turns on and off the mower blades. The parts manual doesn't have a replacement part number for this item. It appears to be part of the main wire harness. Does anyone have any suggestions on how to fix it?
