Three modes match your needs
The TerraLock switch has three positions—off, full-time and automatic. In automatic mode, the TerraLock system engages and disengages frontwheel drive and four-wheel differential lock depending on:
• Steering angle
• Forward ground speed
• 3-point hitch quick raise use
• Brake application
Automatic mode gives you the best performance advantages by delivering optimum traction when traveling straight, then disengaging FWD and diff lock when you turn the steering wheel, to give you better maneuverability. If forward speed exceeds 15 km/h, both FWD and differential locks will also temporarily disengage.
When TerraLock is engaged fulltime, both FWD and differential lock remain engaged until you activate the brakes. You also have the option of turning TerraLock off to completely disengage FWD and front and rear diff lock.
