Abstract

A throttle control system for a tractor having at least three tractor vehicles each of which has its own engine and wheels driven by the engine, in which there is means responsive to change in angular relationship of the vehicles to change the relative settings of the throttles of the vehicles in the rear so that the engine of the vehicle on the inside of the turn tends to operate at a slower speed than the engine of the vehicle on the outside of the turn. There are cables running from a throttle control in the operator's compartment of the lead vehicle to the throttles of all three vehicles, the angle responsive means being effective, when the throttles are in advanced position, to override the action of the main throttle lever and move one of the throttles towards throttle retard position without disturbing the position of the main throttle control.
