Great Plains Terra-Max®

Create a seedbed-friendly finish, level soil and eliminate ruts, size and bury residue, and remove chemical-resistant weeds – all with this one, innovative tillage tool. This hybrid soil management solution gives producers the flexibility to easily adapt to ever-changing weather, seasonal, and soil conditions.

Take control of your adjustment and monitoring needs right at your fingertips with the Implement Command option for select models of Turbo-Max®, Terra-Max®, Velocity®, and Disk Harrow! This system allows you to set, adjust, and monitor your implement on-the-go and in real time – on your ISOBUS-compatible monitor in your tractor cab.

By engineering the rolling spikes to work in a V-pattern, soil and residue are leveled better than ever before.

Combine the benefits of cover crop application and soil management with the Turbo-Seeder™ from Great Plains! Turbo-Seeder™ offers a cost-effective, highly productive method for broadcast seeding cover crops with a vertical or hybrid tillage tool. With Turbo-Seeder™, you can simultaneously till your soil, size residue, and plant cover crops in one pass.

A lengthened frame, opposing left-hand and right-hand rolling spike harrows, and a standard double-basket rear attachment combined with active hydraulic down-pressure, all work together to provide a seedbed-ready, high-quality finish.

By combining some of the best features from TurboBlade from our highly-successful Turbo-Max® and SpeedBlade, featured on the Velocity, Great Plains has created the TurboSpeed blade. The TurboSpeed blade produces unrivaled tillage results by combining the Turbo-wave blade’s soil penetration and breakout capabilities with the scalloped profile of the SpeedBlade™ to drive the blade through the soil.

Achieve exceptional soil management, ground leveling, and residue control with adjustable front and rear coulter gangs. Front gangs adjust from 0 to 8 degrees, while rear coulter gangs adjust proportionally from 0 to 6 degrees.

New 7-lip TillXtreme™ seals on each side of the gang bearings lock in grease and prevent contamination. Additionally, the walking beam pivots utilize coated bushings, eliminating the need for tapered bearings and grease in pivot points. Drop axles pivot on anti-rotational pins, requiring no maintenance.

Multiple rear hitch options in long, short, ball, and flex-tongue configurations are now available. The rear hitches complement the versatility of the Terra-Max® by enabling cover crop, nutrient application, and other light-duty towed attachments. Choices include Cat. 3/4 cast; Cat. 5 cast; or Cat. 4 or Cat. 5 articulating bull pull hitch.
