Features and benefits
Komatsu Traction Control System
Komatsu Traction Control System (KTCS) automatically engages the inter axle lock and the KTCS braking to provide optimal traction in soft ground conditions
Selectable economy and power working modes
Selectable working modes for Economy and Power allows machine performance to be optimised based on demand and operating conditions
Auto idle shutdown
In order to reduce unwanted idle time, Komatsu machines feature Komatsu Auto Idle Shutdown. This function will shut the engine off and apply the parking brake and hydraulic lock after a preset idle time limit
