Claim:
1. A machine, comprising: a frame for supporting the machine; a ground-engaging mechanism positioned to support the frame; a drive unit coupled to the frame and a drive unit controller for controlling the drive unit; a cab coupled to the frame; a control system disposed in the cab, the control system including a control mechanism for controlling the operation of the machine and a control switch to enable a drive unit shutdown and restart (SRS) process; a vehicle control unit disposed in electrical communication with the control mechanism and control switch; a sensor disposed in electrical communication with the vehicle control unit, the sensor configured to detect a movement of the control mechanism; and a SRS control device disposed in electrical communication with the vehicle control unit, the SRS control device comprising a depressible button adapted to be physically manipulated and to communicate a signal to the vehicle control unit indicative of a state of the depressible button; wherein the vehicle control unit comprises a processor and a memory in which instructions executable by the processor are stored for causing the processor to: determine that the control switch is positioned in an enabled position, in response to determining that the control switch is positioned in the enabled position, detect that the control mechanism has been stationary for a defined period of time, in response to detecting that the control mechanism has been stationary for the defined period of time, determine that the machine is operating under a predetermined condition, in response to determining that the machine is operating under the predetermined condition, detect that the SRS control device is depressed, in response to detecting that the SRS control device is depressed, send a shutdown signal to the drive unit controller that is configured to cause the drive unit controller to shut off the drive unit in response to the shutdown signal; and subsequent to sending the shutdown signal and in response to detecting that the SRS control device is in an undepressed state, send a restart signal to the drive unit controller that is configured to cause the drive unit controller to restart the drive unit in response to the restart signal.
