Interlock

Recommended Posts

Ok, I know this is not an AC or Simplicity question, but... Anybody know Grasshopper mowers? I'm trying to help a freind with his grasshopper 718D. It won't crank. If I put 12 volts right to the selonoid, it cranks. There is a module - switch interlock, but I don't know how to test it. Any suggestions? Thanks

Hi, Check the steering handle switches, both handles have to be out to start, also I believe the seat switch has to be operated to start. Engine will run with the brake on and handles out, but will die if the handles are tipped in with the parking brake on. Keeps you from driving with the parking brake on. If the handle switches are OK open the control module and there should be a circuit board with a number of diodes on it. This board is part of a complete harness and it very expensive to replace, probably over 300.00. Just check the diodes and replace any bad ones. The diodes are not available separately from GH, but we get them from an electronic supply house. If you need some, contact me and I can provide them. These are the Cadillac of Zero Turns and last forever. They aren't cheap, but a lot have been 30 yr investments for a lot of people. Al Eden
