LATERAL PLOUGH

摘要

The lateral plough is attached to the hitch assembly of a grader or snow plough and is used to remove selected seg- ments of an elongated pile of gravel or snow. The plough has an arcuate blade for pushing the gravel or snow forward. A gate is attached by a hinge to the outer end of the blade for preventing the gravel or snow from exiting from the blade as the grader or plough advances. The angle of the blade may be adjusted by shortening or lengthening the effective length of a chain which extends from the outer edge of the gate to the blade.
