Vertical Tillage Spring

Manage Residue

The first job of a spring vertical tillage tool is to manage residue. It should chop it into planter-size pieces that can be easily moved with a row cleaner and flow through the planter. The image below shows how the Turbo-Chopper® slices residue in the direction of travel, then the chopper reels chop it perpendicular to the coulters. Turbo-Till®, on the other hand, sizes residue to 5" pieces.

Maintain Density

As shown in the illustration below, the patented Turbo Blade flutes enter the soil perpendicular to the ground, cleanly cutting the residue. As the blade rotates further, it fractures the surrounding soil. As it leaves the ground, it throws soil on top of the residue, lacing it to the ground. Because it never moves soil sideways, there is never any ridging.

Create the Perfect Seedbed

Only Great Plains has the patented rolling spike harrow and reel combination. It is arguably one of the most important parts of a vertical tillage tool and one that is often overlooked by our competitors. The rolling spike works the ground vertically between turbo blades, creating a smooth, level surface on top AND at seeding depth to ensure even emergence.

 

Not All Vertical Tillage Tools are Equal

Concave (Cupped) Blades Individual Spring Coulters Turbo-Till/Max/Chopper
The backside of concave fluted disk blades create compaction layers similar to a disk blade. They also create ridges because they move dirt horizontally. Straight coulters on coil springs work soil vertically but create an inconsistent seedbed because they are forced up in denser soil and tough stalks and work deeper in light soil. Vertically cuts residue, fractures the soil, and creates a perfectly smooth seedbed at plain depth for excellent, uniform emergence with no compaction layers allowing roots to reach nutrients and moisture.
