The Stovebolt Site Forums The Parking Lot Big Bolts question on why three throttles

I have a 1934 Chevrolet 30 cwt or 1 1/2 ton big bolt it has a cable throttle o the dash as well as a foot throttle on the floor and a and throttle on the steering column. can some one explain why this was done the truck was shipped to Australia and the body maker here was Holden body works but i am thinking that the throttles would have been done at its build point in USA. any help would be appreciated. the motor was made on the 5th on September 1934 and was a master and truck motor

Hello psmith,

Welcome to the Stovebolt site. All of the US made trucks made pretty much from the beginning of time up to the automatic choke era have both a hand and foot throttle. The hand throttle is primarily used in initial start up of the engine much like the fast idle cam on later model carburetors. The hand throttle was also used to add RPM for winching, dumping, creeping along in farm fields, or other tasks requiring a little more engine speed. I have never seen a throttle on the steering column. A picture would be great. Hopefully someone with greater knowledge of 1930's vintage Holden's can shed some light on this.

That steering column throttle does not look like original equipment- - - -maybe it's been adapted from a Model A or Model T Ford. The notched quadrant and the lever looks identical to what's on a Model T.

Maybe an early system for handicapped driver?

Model A's used a lever somewhat like yours on the column to adjust the mixture. I haven't a clue why.

On Model A's the left hand lever was manual spark advance (there was no centrifugal or vacuum advance) and right hand lever was throttle. The mixture adjustment was a knob on the right side below the dash that connected to a rod going down to the carburetor. It served a dual purpose of choke (pull out) and mixture adjustment (turn).
