The present disclosure is directed to a control system for a power machine that provides selected resolution of the adjusted speed control and other controls, such as attachment controls, to provide more options to the operator for fine positioning. The present disclosure includes a control system for a power machine. The power machine has a full speed. The control system has an adjustable propulsion controller that an operator can position along a range of movement. Examples of the adjustable propulsion controller include a joystick or an accelerator. The position of the propulsion controller along the range of movement selects the speed of the power machine between a first speed and a second speed, where the first speed is greater than the second speed. The first speed is selectable from a plurality of percentages of the full speed.
