Abstract
A speed control system for an agricultural system having an agricultural vehicle includes a control system. The control system instructs an engine to maintain a constant speed, determines a first estimated speed of the agricultural vehicle associated with increasing a gear index of a step ratio transmission, determines a second estimated speed of the agricultural vehicle associated with decreasing the gear index of the step ratio transmission, instructs the step ratio transmission to increase the gear index if the first estimated speed is closer to a target speed than the second estimated speed and a current speed of the agricultural vehicle, and instructs the step ratio transmission to decrease the gear index if the second estimated speed is closer to the target speed than the first estimated speed and the current speed.
