Auto Idle
 
Save fuel with Kubota's Auto Idle. Reduce engine RPM instinctively when high engine speed isn't needed.
 
When the control levers are in neutral for more than 4 seconds, the engine RPM automatically idles. Move any control lever and the engine RPM immediately returns.
 
This innovative feature reduces noise and exhaust emissions while reducing operating costs.
