Product Description

Discover why there’s more to the Max.

One of the industry-leaders in vertical tillage is the Great Plains Turbo-Max, offering both agronomic benefits of both spring vertical tillage and fall residue management. In the fall, the Turbo-Max can be run at an angle to bury more residue. This aids in the decaying process and pins the residue to the ground. In the spring, the Turbo-Max can be run straight to create the ideal seedbed to allow for precision planting.

The Turbo-Max is the ideal vertical tillage tool 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. The Turbo-Max also does not create compaction layers, which allows roots to have the freedom to reach nutrients and moisture.

With new sizes and features, the Turbo-Max also offers producers more flexibility and control than ever before. With new working widths ranging from 8.5' to 48', operations of all sizes have access to these vertical tillage tools. Features like the hydraulically-adjustable tongue allow for easy front-to-back leveling and the new hydraulically-adjustable finishing reel helps prepare the optimal seedbed.

The Turbo-Max helps producers accomplish more with attachments like the Turbo-SeederTM, allowing producers to till and plant cover crops all in one pass. The hydraulically-adjustable gang angles cover residue in the fall at 3 to 6 degrees and prepare the ideal seedbed at 0 degrees. Turbo-Max blades are spaced 7½" apart on two rows of coulter gangs. Rear gangs offset the front gangs, splitting the blade spacing to 3¾" for superior residue sizing in one pass. Turbo-Max provides truly vertical cutting without the shearing caused by concave blades.

NEW Features

  • NEW hydraulic tongue for easy front-to-back leveling
  • NEW hydraulic adjustable finishing reel to prepare the optimal seedbed
  • NEW sizes ranging from 8.5’ to 48’ to perfectly match your operation
  • Hydraulically adjust gang angle from 0 to 6 degrees on the go for convenience
  • Add Turbo-Seeder to select Turbo-Max models for single-pass cover crop application

Turbo-Seeder™ cover crop attachment available for 1200TM, 1500TM, 1800TM, 2400TM, 3000TM, 3500TM, and 4000TM Turbo-Max models.

Product Features

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°.

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.


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".

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.

Rolling Spike and Reel Rear Attachment
Rolling Spike and Reel Rear Attachment

Rolling spike harrow tines split Turbo Coulters to ensure thorough mixing of soil and residue and provide a smooth, uniform seedbed for optimum planter performance. The rear reel leaves the surface planter-ready by firming soil, removing air pockets, and eliminating clods.

Hydraulic Tongue
Hydraulic Tongue (optional)

Optional Hydraulic Tongue allows front-to-back leveling on-the-go from the cab of the tractor.

Hydraulic Reel (Optional)
Hydraulic Reel (Optional)

The optional 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.

Great Plains Exclusive Maintenance-Free Bearings
Exclusive Maintenance-Free Bearings

Reduce maintenance time and extend life of bearings. These 360° self-aligning bearings are never sideloaded. A six-lip seal on each side locks in grease and prevents contamination. Additionally, the walking beam pivots utilize Teflon™-coated bushings, eliminating the need for tapered bearings and grease in pivot points.

Fall Tillage: How to Deal with Ruts

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

A rainy fall harvest season has caused wet soil conditions and moderate to severe ruts in many fields across the country. These ruts must be fixed before spring planting. Fall tillage needs to eliminate the ruts to ensure a good, uniform seedbed in the spring.

Farmers should analyze the severity of the ruts, then choose the tillage tool that matches their specific field needs—in many cases, the solution may involve a two-pass system. Our full line of tillage equipment is designed to meet the needs of each operation and eliminate ruts in a variety of field conditions.

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:

"Great product!" | Great Plains Turbo-Max®

From Tommy W., North Texas:

"This has been one of the best things I've ever purchased! Great product!"

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!"
