Abstract
A trench leveling blade is movably mounted between a pair of side walls which are slotted to receive the bucket of a backhoe or other excavating machine. The blade is vertically adjustable with a hand operated jack screw. Rollers mounted in front and back of the blade support the blade during use and guide the blade during its vertical adjustment. A pair of adjustable scraper blades is provided on opposite sides of the leveling blade to clean the surface of the pavement adjoining the trench or any other surface being worked by the leveling blade.
