Auto Idle System
 
Kubota’s Auto Idle System improves safety, decreases noise and reduces fuel consumption. The engine automatically decelerates to idling speed four seconds after the control levers are returned to their neutral positions. When a control lever is subsequently moved, the engine speed automatically returns to its prior setting. A simple twist of the Dial Accelerator smoothly coordinates speed and tachometer settings.
