Abstract

A snow plow is pivotally mounted to a tractor by a compound mount allowing for multiple blade positions. The mount has an inner portion pivotally mounted about a first horizontal axis to the front of the tractor and an outer portion pivotally mounted about a vertical axis to the inner portion. The plow blade is pivotally mounted about a second horizontal axis to the outer portion. Deicer nozzles spray liquid and a spreader distributes salt and other materials in front of the front wheels of the tractor.
