Hi there, I am trying to help my landlord to get his tractor functioning properly. It was started by hot wiring in the past and I am trying to get it back to starting with a key. I believe the clutch safety was bypassed but am not able to locate it. Can anyone point me in the right direction to locate the safety switch?
Removing hotwire start method. Yanmar 155d

If it were me and I did not have correct location of switch, I would crawl under the beast and inspect all components of clutch linkage....Not going to a lot of mechaniocal stuff to look at, and there will probbl be a switch close to pedal or where throwout shaft goes into belhousing...

Look around the clutch mechanism for a switch as WranglerX suggested, but Tractor Data indicates the 155d was made from 1976-1979. There may not have been a safety switch on the clutch in those years.
Hadn't thought about it not actually being there. I will take one more hard look and maybe I can figure out how to install one 
thank you.thepumpguysc

I see this hasn't been resolved - or the OP never came back.
There's likely a second similar safety switch at the PTO lever. Too many times I've shut down while mowing or tilling then wondered why I couldn't restart until I remembered to disengage the PTO.
