IMPORTANT: Engage differential lock before entering situation where wheel slippage may occur or when all wheels appear to be turning at same speed. If engaged after wheels begin to spin, damage to differential could result.

Differential Lock latches front and rear wheel axles together to provide best traction possible for slippery field conditions.

Engage differential lock by selecting either of the two operating positions:

Auto Lock — Enter auto lock by pressing AUTO lock switch (A) on CommandARM™. When in auto lock, AUTO lock switch and differential lock indicator (C) are illuminated. Differential lock indicator turns on or off depending on engagement state of differential lock.

• Differential lock disengages when any of the following conditions are met:
  • At startup
  • Wheel speed is more than 23 km/h (14 mph)
  • Brake pedal is depressed
  • Foot decelerator (E) is depressed
  • Steering angle greater than selected value

Differential lock disengagement steering angle may be user selected. See Adjust Steering Angle to Disengage Differential Lock in this section of this Operator’s Manual.

• Engages when all the following conditions are met:
  • Wheel speed falls below 19 km/h (12 mph)
  • Steering angle less than selected value
  • Brake is released

Manual Lock — Enter manual lock by pressing either manual lock switch (B) on CommandARM™ or differential lock floor switch (D). Differential lock will return to previous operating state if manual lock switch or differential lock floor switch are pressed again. When in manual mode, manual lock switch and differential lock indicator are illuminated.
