AP grading boxes

AP Machinebouw has been producing grading boxes for more than 30 years. Thanks to many years of experience, close contacts with the users and practical thinking, the AP grading box has been put through many alterations which resulted in a range that offers the ideal grading box for every imaginable situation. The solid construction guarantees a long life-span.

Due to the special angle of the knife the AP grading box will easily go into any soil at any time. The unique curve of the blade keeps the ground “rolling” which results in a higher capacity, and less tractive power required. The special wheel system assures the grading box to move stable, avoiding “bouncing”, even at a speed of 10km per hour or more.

All AP grading boxes can be equipped with laser control. For further options see “Brochures”.

AP grading boxes can also be made to customer specific requirements.
