A control system for a work machine. The control system allows an operator to selectively maintain control of a ground drive, a work tool, or both the ground drive and the work tool. The system provides a foot pedal movable between multiple positions. The foot pedal allows an operator to selectively hold the position of one or both of the ground drive control and work tool control. When the foot pedal is in a first position, the work tool control and ground drive control are not affected. When the foot pedal is in a second position, the position of the work tool control is maintained, while the ground drive control is not affected. When the foot pedal is in a third position, the position of the work tool control is maintained and the position of the ground drive control is maintained. A work tool control lock is used to prevent the work tool control from engaging when the foot pedal is in the second position or the third position.
