Product Description

The Industry Standard in Vertical Tillage

True vertical tillage has become the go-to method for yield-boosting seedbed preparation. Turbo-Max is the industry leader in vertical tillage tools, especially for min-tillers who want to size and anchor residue without aggressively working the ground in the fall. It vertically cuts residue and fractures the soil to create a smooth seedbed for uniform seed emergence. Because Turbo-Max is a true vertical tillage implement, it does not create compaction layers, giving roots the freedom to reach nutrients and moisture.

Now with exciting new updates, the industry-leading Turbo-Max offers even greater agronomic benefits and operator convenience. Introduced in fall 2019, the NEW Implement Command® system allows producers to control, adjust, and monitor their Turbo-Max from the comfort of their tractor cab. Implement Command is available on new 18'-48' Turbo-Max models.

New for 2020, Turbo-Max also features hydraulic fore/aft leveling and hydraulic rear reels as a standard feature on select sizes. Hydraulic fore/aft leveling allows the operator to easily adjust and level the implement from the cab without any wrenches or tools needed. It also allows the machine to be tilted forward for road transport or to quickly change between tractors. Hydraulic rear reels allow the operator to control the reel down pressure from the cab to adjust for different field conditions. This allows the rear attachment to be lifted in less-than-ideal field conditions, saving time spent cleaning mud out of the reel.

With working widths ranging from 8.5 to 48, operations of all sizes have access to the benefits of vertical tillage. Each Turbo-Max is designed with two rows of coulter gangs, with blades spaced 7½" apart. The rear gangs offset the front gangs, splitting the blade spacing to 3¾" for superior residue sizing in one pass. This allows the Turbo-Max to provide true vertical cutting without the shearing caused by concave blades.

The gangs can be angled from 0 to 6 degrees, making the Turbo-Max a multi-seasonal tillage tool. In the fall, angle the gangs from 3-6 degrees to cover more residue, or keep the gangs straight to prepare the perfect seedbed in the spring. Hydraulically-adjustable gangs are offered as a standard feature on the larger models, and as an option on the smaller sizes.

Turbo-Max helps producers accomplish more with attachments like the Turbo-Seeder™, allowing producers to till the soil and plant cover crops – all in one pass. The Turbo-Seeder cover crop attachment is easy to install and comes with either a 24 or 45 cu. ft. hopper.

Product Features

Implement Command
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
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 Tongue
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
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.

Great Plains Exclusive Maintenance-Free Bearings
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 and Reel Rear Attachment
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.


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".

How to Deal with Ruts

Before and After: Turbo-Max® Vertical Tillage Implement
November 11, 2014

Stuck in a rut? Not for long!

With all the additional moisture during fall harvest, the conditions have led to moderately to severely rutted fields around the country. To ensure a nurturing, uniform seedbed and avoid yield-loss, these ruts must be removed prior to spring planting. Ruts cause problems for all types of producers, but they can become an especially unique problem in low disturbance no-till fields. No matter your tillage preference, Great Plains has a solution to combat a variety of field conditions.

What to look for in a vertical tillage tool

When selecting a vertical tillage tool, producers should keep several factors in mind:

Which Vertical Finish Tool is Right for Me?

Great Plains Tillage: Turbo-Till®
March 10, 2015

A vertical tillage system requires producers to maintain uniform density in the soil profile. Vertical finish tools prevent the creation of additional compaction layers in the soil, especially after less-than-ideal planting or harvest seasons. A good vertical finish tool will establish an ideal seedbed to allow precision seed placement by the planter.

Producers should consider several factors when selecting a vertical finish tool:

Testimonial Video

From Blake L., Nova, OH:

"The Turbo-Max has been the best tillage tool we've ever run. It works for everything from hay ground to beans and corn. Definitely one of the best on the market! Very happy with it!"

From Hayden J., Reddick, IL:

"Love running this tool every fall. So much fun going faster!"

From Jed K., Centerville, PA:

"Our Turbo-Max is a great finishing ground tool for leveling and getting the soil ready to be planted. This vertical design allows us to keep rocks from surfacing and retain the smoothness for harvesting season. With the ability to angle the gangs, it re-levels areas that are rough in places to keep ground in best condition. This Turbo-Max has been a great tool for our tillage and planting regimen. Thank you, Great Plains Ag!"

From Mathew S., Wooster, OH:

"I purchased a Turbo-Max 1800, and it had been an excellent tool to prepare a perfect seedbed. This machine work as advertised!"

From Ron K., Eastern Pennsylvania:

"WORKS GREAT! Used a Salford prior, but was not happy with the job it did. We rented a Turbo-Max for a trial comparison, and the Turbo-Max performed much better. It leveled the ground much better, it cut up the stalks much better, and we like to be able to angle the blades 6 degrees to close water ditches. We're very happy on our decision to buy the Turbo-Max!"
