ABSTRACT:
A combine is provided with a ground speed control having manual and automatic operating modes. In the automatic operating mode, ground speed is adjusted to achieve a predetermined level of combine harvesting efficiency. A manual lever for controlling the ground speed includes a lost motion connection with a ground speed control member permitting it to be shifted between automatic and manual operating modes. Manual movement of the lever in a speed controlling direction while harvesting in the automatic operating mode will diestablish the automatic operating mode and reestablish a manual operating mode. Subsequent release of the lever allows resumption of an automatic operating mode.
