On a steep uphill pull in the summertime, set the throttle wide open in whatever gear it takes to pull the hill at walking speed or so, then climb out on the running board to steer and get away from the heat inside the cab. I've seen pictures of big rigs pulling the Grapevine Hill in California that way.

I also believe that one of the intended uses for the throttle knob was running PTO equipment. All the AD 4 speed trucks have the side plate on tranny for mounting a PTO, not sure about the 3 spd's.

An excellent time to put the spigot to use as well, draining spent coffee. On the 250 HP, 88,000# GVW semis I started on, there was no shortage of opportunities to get out. Sometimes you could walk faster than the truck was going..

I used my throttle cable to inspect my truck while it rolled down the road as it was only going slowly it let me walk around it while I looked it over top to bottom to see if all things were correct and working properly.

When I drove my 52 in the winter I'd get it started in the morning by using the choke as normal and as soon as possible push the choke all the way back in, set the throttle to run at a fast idle, then turn on the fan/heat. Go inside for breakfast and come back out to a nice and warm and defrosted truck.

I tried the throttle knob as a cruise control on long trips, it's not worth the trouble, and probably not all that safe or recommended either. Even in the mid west in the long flat and straight roads you still need to constantly adjust the throttle ever so slightly, so no point in using the one in the dash.

You wouldn't happen to have a copy of those pictures, would you? That sounds like it'd be interesting to see.

Nope, they were on the wall of the office of a trucking company I drove for in California. Back in the late 40's and early 50's, 30 years before my time as a driver, Grapevine was a real challenge, 2-lane road in some places, lots of switchbacks, and "slow truck" lanes on the really steep parts. The big rigs were either running BIG gas engines, or some of the early Diesels like the Cummins 220. They usually had 5X4 transmissions, and sometimes a manual-shift 2-speed rear end to really give them some gear-splitting ability. 40 forward speeds!

That practice continued into the 60's. I bought my first 18 wheeler in March of 1964. We would stand out on the running board not only to get away from the heat, but on a 1st gear hill it wasn't that uncommon for a drive shaft or input shaft to break or an engine to blow up. We knew that we couldn't hold her on the hill and we wanted a head start on jumping clear of the darn thing. Film and photo developing cost money which no one had. And we thought the practice would last forever.

We used to use the throttle on our cattle truck in the field searching for newborn calves. You could set the throttle, get out of the cab & stand on the window opening to get a better view & to grab a hold of the steering wheel if need be. Hadn't thought about that in years!! Try it today & see what happens!!???

Probably not done too much anymore because of safety issues. A friend of mine set his throttle while out in the field and had one of the kids steer while the rest of the kids helped with picking stones. Not long after, one of his kids fell and got run over.
