Abstract

A snow plow including a control unit for controlling the raising and lowering of an auger housing, a reset switch that can be operated by a worker, and a reset display light that illuminates in conjunction with the turning on of the reset switch. The control unit automatically raises and lowers the auger housing in accordance with the reverse and forward traveling of travel device, and automatically adjusts the auger housing to a horizontal position during forward travel of the travel device upon receiving an on signal from the reset switch. The control unit maintains the illuminated state of the illuminated reset display light according to the turning on of the reset switch, even when the travel device is traveling in reverse, and extinguishes the reset display light upon receiving a termination signal for terminating snow plowing work performed with an auger.

First claim

What is claimed is:

1. A snow plow comprising a travel frame having a travel device, an auger housing having an auger and being capable of being raised and lowered relative to the travel frame, a raising/lowering drive mechanism for raising and lowering the auger housing, and a control unit for controlling the raising/lowering drive mechanism;
wherein the snow plow comprises a reset switch adapted to be operated by a worker, and a reset display light that illuminates in conjunction with turning on of the reset switch,
the control unit controls the raising/lowering drive mechanism so as to raise the auger housing when the travel device travels in reverse and lower the auger housing when the travel device begins to travel forward, and so as to automatically adjust the auger housing to a horizontal position during forward travel of the travel device upon receipt of an on signal from the reset switch, and
the control unit performs a control so as to maintain an illuminated state of the illuminated reset display light according to the turning on of the reset switch, even when the travel device is traveling in reverse, and to extinguish the reset display light upon receipt of a termination signal for terminating snow plowing work performed with the auger.
