Work vehicles

Abstract

The aim is to facilitate snow removal work, which involves frequent switching between forward and reverse movement. [Solution] In a work vehicle equipped with a snow removal device 2 that repeatedly moves forward and backward to perform snow removal work, a positioning device 13 for determining the position of the machine is provided, a forward / reverse switching means 12 is provided, a work travel path acquisition means M for storing the work travel path Pa during forward operation of the machine is provided, and a non-work automatic steering control means R for reversing along the work travel path Pa when not performing reverse operation is provided.

Claims

1. A work vehicle equipped with a snow removal device (2) that repeatedly moves forward and backward to perform snow removal work, the work vehicle is provided with a positioning device (13) for determining the position of the machine, a forward / reverse switching means (12), a work travel path acquisition means (M) for storing the work travel path (Pa) during forward operation of the machine, and a non-work automatic steering control means (R) for reversing along the work travel path (Pa) when not reversing.

2. The work vehicle according to claim 1, configured such that automatic steering by the non-work automatic steering control means (R) is not performed when the machine is stopped.

3. The work vehicle according to claim 2, wherein when the forward / reverse switching means (12) switches from reverse to neutral, the automatic steering by the non-work automatic steering control means (R) is discontinued, and when it switches from neutral to forward, the work travel path acquisition means (M) updates the work travel path (Pb) to a newly acquired work travel path.

4. The work vehicle according to claim 3, wherein when the forward / reverse switching means (12) switches to forward during automatic steering by the non-work automatic steering control means (R), the work travel path (Pb) newly acquired by the work travel path acquisition means (M) is updated in front of the switching point, but the work travel path (Pa) behind the switching point (Q) is not updated.

5. The work vehicle according to claim 4, configured to start the operation of the work travel route acquisition means (M) based on the operation of the work route acquisition start switch (23).
