I am pulling my hair out trying to figure this out. I have a Husqvarna YTH21K46 with a Kohler SV610-0212 engine. It seems the safety switches aren't working in sync with each other. When I hold the clutch safety switch in, the mower will start and engage the blades. When I let go of the switch the mower dies. When I am holding the button in while the mower is running and release the brake the mower dies. Can someone help me please?
