Most trucks did not have PTOs but almost all Advance-Design and New Design trucks had throttle cables, except the Hydra-Matic-equipped trucks in 53/54-55. I wonder if the larger Hydra-Matic-equipped New Design GMC trucks (with and without PTOs) had a throttle cables?
I'll be using the throttle on my COE with a PTO and a winch, I hope.
I have always used the throttle cable to
aid in starting, as described in the Owner's Manuals. Hydra-Matic trucks had an automatic choke and maybe a fast-idle setting? Also, I have sometimes used the throttle control when starting from a full-stop, in traffic, on a hill - this is not really necessary, just a matter of convenience.
