Differential
A differential divides the power that is transferred to the wheels or causes balanced power to be sent to the wheels. During a turn the differential allows one wheel to rotate slower than the other. during a turn the differential allows the inside wheel to rotate at a slower rate in relation to the outside wheel. The differential will send equal power to both the inside and outside wheels during a turn.Straight Forward or Straight Reverse Operation
Straight machine travel with the same amount of traction under each drive wheel, has the same amount of torque to each drive wheel.Operation During a Forward Turn or Operation During a Reverse Turn
When the machine turns, the inside wheel is more resistant to rotation. This resistance causes different torques on the opposite sides of the differential. The outside wheel will rotate with less resistance than the inside wheel. The outside wheel will begin to rotate faster than the inside wheel.Loss of Traction (Wheel Slippage)
If one wheel loses traction, the pinion gears of the wheel that is maintaining traction will begin to rotate slowly around the side gear. The slipping wheel increases speed until the maximum wheel speed is obtained, or the remaining drag is equal to the torque on the opposite side. The maximum amount of torque transmitted to the tire not slipping is equal to the torque on the tire that is slipping.Differential Lock
The button for the differential lock is on the joystick. Push button and hold the button to lock the differentials. Release the button to unlock the differentials. The differential lock will activate if the machine speed is less than 5 km/h (3 mph). It will deactivate when the speed is greater than 10 km/h (6 mph), or when the button is released and the speed is less than 10 km/h (6 mph).
