ABSTRACT:
A basic land leveller has the side plates and moldboard carriers. Angle irons are welded to the top of the carriers to form the moldboard carriers into a rigid structure and to form a guide for the wheel booms extending behind the leveller and a tongue extending in front of the leveller. The equipment is shipped with the wheel booms and tongue aligned with the moldboard carriers and the buyer bolts the booms into the boom guides and the tongue into the tongue guides.
The moldboards are formed of a plate broken three times to form three panels with a blade bolted to the bottom panel.
