Abstract:
1. A power machine having a power source and separately controllable left and right side tractive elements for enabling travel of the power machine, the power machine comprising: a control system coupled to the power source and to the left and right side tractive elements, the control system configured to selectively provide power from the power source to the left and right side tractive elements; first and second user input devices configured to provide an actuation signal indicative of manipulation between a neutral state and a forward state; a manipulable electronic tag-along input device configured to provide a tag-along activation signal; and a controller in communication with the first and second user input devices, the electronic tag-along input device, and the control system, and configured to control the left and right side tractive elements in a regular mode and in a tag-along mode, wherein in the regular mode, the controller signals the control system to control the left side tractive element responsive to actuation of one of the first and second user input devices and signals the control system to control the right side tractive element based on actuation of the other of the first and second user input devices; wherein in the tag-along mode, the controller signals the control system to control both the left and right side tractive elements responsive to actuation of the first user input device; and wherein the controller enters the tag-along mode from the regular mode when each of the actuation signals of the first and second user input devices indicate manipulation to the forward state and the electronic tag-along input device provides a tag-along activation signal and the second user input device is moved so that its actuation signal indicates manipulation to the neutral state.
