MANUAL EXTRACT TRAVELING IN A STRAIGHT LINE
1. When there is no imbalance between drive force of left and right wheels. Road surface condition, friction coefficient, and load for left and right wheels are uniform and load on bucket is centered exactly. The power from the transmission is divided equally to the left and right by the differential gear. In this case, the wheel slip limit of the left and right wheels is the same, so even if the power from the transmission exceeds the wheel slip limit, both wheels will slip and the differential will not be actuated. There is no load on the brake at the rear face of the side gears.

2. When there is an imbalance between the drive force of the left and right wheels, road surface condition, friction coefficient and load for the left and right wheels are not uniform and it is easier for the wheel on one side to slip.

Example 1 When digging, and the wheel on the one side is on a soft surface.
Example 2 When clearing snow, and the wheel on the one side is on snow and the wheel on other side is on asphalt.
Example 3 When traveling on a slope, and there is an imbalance between the load on the left and right
wheels.

3. The power from the transmission is divided equally to the left and right by the differential gear. However, when the drive force exceeds the wheel slip limit on the side where the wheel is slipping, the amount of the force exceeding the wheel slip limit passes through the brake and case at the rear face of the side gear and is transmitted to the brake on the opposite side, locked side, and is sent to the wheel on the locked side. If this excess portion of the drive force becomes greater than the braking force, the differential starts to work.
