成してある農作業車のクローラ走行装置。 A movable track frame 6 on which four groups of ground wheels guiding the crawler belt 5 are pivoted is pivotally connected to a frame 7 fixed to the body side via a swing link mechanism 14 so as to be able to rise and fall freely, and is connected to an electromagnetic valve 27. Accordingly, the movable track frame 6 is moved up and down by the telescopic drive of the hydraulic cylinder 11 whose operation is controlled, and detection switches 29a and 29b are provided to detect when the hydraulic cylinder 11 has reached the end of its telescopic stroke. , a crawler traveling device for an agricultural vehicle configured to return the electromagnetic valve 27 to neutral based on the detection of the detection switches 29a and 29b, wherein the hydraulic pressure on the upward direction side of the movable truck frame 6 with respect to the body of the vehicle is Stroke end position E of cylinder 11
The crawler traveling device for an agricultural vehicle is configured such that the detection switch 29a is located at an intermediate position in the detection operation area W of the detection piece 31a provided in the detection switch 29a.
