    Automated speed demand. Excavators use an Auto-Idle facility, based on a switch in the cab. With Auto-Idle off, the machine speed demand causes the engine to run at target speed. With Auto-Idle on, an engine operating at the target higher speed returns – after a delay – to the target low idle speed when the machine is no longer productive.
