It has been discussed many times but I know what a hassle it is to find anything in search.

The main use for the throttle would be for PTO operated equipment. Why it was standard on AD pickups is anyone's guess but people found uses for them.

When I was in my early teens we were visiting my uncle's dairy farm. My cousin asked if I wanted to help him feed. He put a few bales in the bed of the AD and I hopped in the cab. When we got to the pasture he put it in granny and set the throttle. He then got out of the truck and got in the bed and started tossing hay. I sat there in the cab amazed.
