NEW IMPLEMENT COMMAND®

Take control of all your adjustment and monitoring needs right at your fingertips with the new Implement Command option for select models of Turbo-Max and the all-new Terra-Max! This system allows you to set, adjust, and monitor your implement right on your ISO-compatible monitor in your tractor cab.

HYDRAULIC REEL 

The hydraulic reel allows you to conveniently adjust down pressure or lift out of the ground with in-cab hydraulic operation. An easy-to-read pressure gauge allows for easy down-pressure monitoring from the tractor seat! This design maintains travel regardless of the selected down pressure. A hydraulic cylinder is used to preload down-pressure springs. When field conditions are not ideal, the harrow can be raised completely out of the ground. The hydraulic reel is now standard on 18' and wider models and optional on 12' and 15' units.

HYDRAULIC FORE/AFT LEVELING

The hydraulic tongue allows the operator to perform fore-and-aft frame leveling on-the-go. Changes are made from the comfort of the tractor cab – no tools or wrenches are needed! This feature is now standard on 18' and wider models and optional on smaller units.

HYDRAULICALLY-ADJUSTABLE GANG ANGLE FROM 0-6° ON-THE-GO

Sizes and covers residue in the fall at 3° to 6° and prepares the ultimate spring seedbed at 0°.

TRUE VERTICAL TILLAGE MACHINE

With 20" Turbo Coulters spaced 7½" apart, Turbo-Max provides truly vertical cutting without the shearing caused by concave blades. Offset front and rear gangs achieve an effective residue cutting width of 3¾" when running at 0°, which is recommended for seedbed preparation.

HYDRAULIC WEIGHT TRANSFER IS STANDARD (MODELS 18' AND LARGER)

Creates an even and constant downforce across the entire width of the implement, assuring uniform penetration and eliminating the possibility for wings to float.

EXCLUSIVE MAINTENANCE-FREE BEARINGS

These 360° self-aligning bearings are never sideloaded. A six-lip seal on each side locks in grease and prevents contamination, which reduces maintenance time and extends the life of the bearings.

ROLLING SPIKE HARROW

The rolling spike harrow tines work with the rear reel to create a smooth, uniform seedbed for optimum planter performance. The tines split the turbo coulters to ensure the thorough mixing of the soil and residue, while the rear reel leaves the surface planter-ready by firming soil, removing air pockets, and eliminating clods.

7½" BLADE SPACING

Turbo-Max features two gangs — each with 7½" spacing between coulters — with the rear gang offset from the front gang. The gangs work together to size residue to an industry-leading 3¾".
