Beschreibung
Zusammenfassung:	A mechanical front wheel drive roller wedging control system includes a 4WD switch in a vehicle operator station, a roller cage drag mechanism electrically activated by the 4WD switch and providing a drag on a roller cage if the 4WD switch is in an on position, and a throttle pedal switch actuated by the throttle pedal and that deactivates the roller cage drag mechanism when the throttle pedal is released. The roller cage drag mechanism may include a solenoid with a plunger, the throttle pedal switch cutting power to the solenoid when the throttle pedal is released. The roller cage drag mechanism may include an electromagnet, the throttle pedal switch cutting power to the electromagnet when the throttle pedal is released.
