It is possible to lock the interaxle differential only. Alternatively, the interaxle differential and all three axle differentials can be locked simultaneously.
Refer to Operation and Maintenance Manual, "Differential Lock Control".

The differential locks must be disengaged when you operate the machine and ground conditions are good. Panel switch (1) must be in the OFF position and the floor switch (2) must not be pressed.
Engage the interaxle differential lock when you are operating the machine and the drive wheels encounter loose surfaces or slippery surfaces. Panel switch (1) must be in the OFF position and floor switch (2) must be pressed. Torque is transmitted to the axle that has traction.
Disengage the interaxle differential lock when the ground conditions improve. Disengage the interaxle differential lock by releasing floor switch (2) .
When you are operating the machine in very soft ground conditions, the engagement of the interaxle differential may not keep the machine moving. Engage the interaxle differential lock and the axle differential locks in order to keep the machine moving. Panel switch (1) must be in the ON position and floor switch (2) must be pressed. The interaxle differential lock and the axle differential locks are engaged. This overrides the normal operation of the interaxle differential and the axle differentials. Torque is transmitted to the wheel that has traction, even though other wheels do not have traction.
Disengage the axle differential locks when the ground conditions improve. Move panel switch (1) to the OFF position in order to disengage only the axle differential locks. The interaxle differential lock remains engaged. Disengage the interaxle differential lock by releasing floor switch (2) .
The interaxle differential lock and the axle differential locks can be engaged while the machine is moving.
Never operate the machine on firm dry ground when the interaxle differential lock and the axle differential locks are engaged.
