Claims

[Scope of utility model registration request]

In an agricultural tractor equipped with a front wheel configured as a steering and driving wheel, only one axle housing on which one front wheel is mounted can be adjusted in distance relative to a differential housing that accommodates a differential device for the left and right front wheels. A tread changing device is provided to change the front wheel tread, and the position of the center pin that connects the differential housing to the aircraft body is adjusted to the left and right of the input end position of the input shaft that transmits input into the differential housing.
The front wheel position changing device is characterized by being configured so that it can be changed between one side and the other side.
