Claims

[Scope of utility model registration request]

In a mobile agricultural machine in which left and right front wheels driven via a differential mechanism are connected via a tie rod and can be steered by a steering mechanism, the differential mechanism is placed in a deflock state and a defroc released state by detecting the tie rod position. When the aircraft is steered in a straight line, the differential mechanism is regulated to a differential state, and when the aircraft is steered in a circular motion, the differential mechanism is released from the deflock state, and the left and right front wheels are placed in a differential state. A deflock release device for mobile agricultural machinery.
