can someone give me the general background on new Holland replacement seats? I bought a used skid loader and it's still at a friends house who is looking over it. I'm trying to research seats. Apparently there are pressure switches either one or two that go with these seats to ensure the seatbelt is on and I'm not sure what the second switch would be for, before you start the machine, the switches have to be engaged. Seller has owned the skid since 1998 and doesn't remember anything about the switches. I'm assuming he bypassed them. Any suggestions or background on this would be helpful. I'm not sure if switches are part of the purchase of a new seat, or if the switch is part of the skid loader, and the seat fits around them? any information would be helpful!
