Thanks for the idea. We had thought about the over ride switch. Had not thought about the diode or buzzer. I think it will be easier just to install the whisker switch. Darrin has gotten used to turning off the auto swath as a temporary work around on the DB60 when he approaches a terrace he thinks might be a problem so I think we are covered till the switch comes in. We had one of the whisker switches on hand and he already has it installed on the 1790 which I run and it seems to work fine in the shop. He will put the other one on the DB60 when it gets here. He already has figured out where he wants it and will be a simple "weld the bracket in place" deal. The existing wire will reach. May be able to plant again by Monday afternoon or Tuesday.

Thanks for all your help to us and everyone else on this forum. You have helped an untold number of people.
