This is a Grade King Leveling Scraper with an Aggression bar installed

The aggression bar is mostly used in road grading applications.

It has the capability to cut up to 2 inches deep and bring the old gravel back up to the surface.

This greatly decreases the amount of new material needed to maintain a gravel road.

The operator can use a variety of different blades to get the results he is needing, including a stinger blade (shown). 

The aggression bar is simply bolted onto the Grade King, which makes it easy to remove.

The aggression bar is made from mostly 1 inch thick steel bar.
