Maximus Overall


Choose from 6’ or 7’ base with several options to provide the width and tillage aggressiveness for your operation.  The tillage piece is powder-coated in implement red to resist corrosion.  

Maximus Gang Adjustable


Both front and rear gangs feature tool free, gang-positioning adjustability from the traditional X-shape to a diamond-shape to match the desired level of tillage aggressiveness and width.  The 3-point hitch can be attached to either front or rear of the disk, mounting to tractors with rear or front 3-point hitch.  The heavy-duty 3” x 3” and 2” x 6” welded steel frame provides durability and consistent, uniform penetration.

The Maximus disk blades feature 9” spacings and are mounted on 1-3/4” round shaft for maximum durability.  Triple-lipped greaseable bearings with 10,800 lbs. of dynamic-load rating provide long life.  Disk blades are available in smooth or notched front/rear combinations to match your needs.  They also feature tool-free adjustable working width in 2” increments.


Maximus Scraper


Add the depth-adjustable, furrowing shovel that can be positioned between the front gangs or the middle of the disk, the aggressive Rolling Harrow® basket, blade scraper skit to eliminate buildup, width-adjustable side shields or bolt-on blade extensions to expand working width by 1’5” all to fit your desired needs.
