A speed and direction controller for selectively providing infinitely variable and incremental control of groundspeed of an agricultural vehicle. The speed and direction controller may communicate with a control system for controlling groundspeed of the agricultural vehicle. The speed and direction controller may include a forward-neutral-reverse (FNR) lever and incremental control elements located on the FNR lever. The FNR lever may be infinitely variable between a maximum forward position and a maximum rearward position, corresponding with a maximum forward groundspeed and a maximum rearward groundspeed, respectively. The incremental control elements may be manipulated by a user to send a signal to the control system for increasing or decreasing the maximum forward or rearward groundspeed by a predetermined amount. This increase or decrease in the maximum forward or rearward groundspeeds may be used by the control system to scale speed commands received from the FNR lever.
