I have a 720 that has the transmission lock on the PTO shaft cover. At what serial number was this started. The front axle is all orange vs black along with the heavy caps on the spindles.

I don't think the manual will tell you that. but it should tell you what you have. Those folks have a phone number and they may be able to help you. http://www.ssbtractor.com/tractor_manual_display.cgi?m=Allis%20Chalmers&o=720%20#26

What type of transmision lock are you refering to? Can we get a picture of it?

Dave, I think the one on the trans cover. It was an OSHA sotra thing, I think.....
