Sunflower 6630/6631 Vertical Tillage: 20' 2" to 37' 5"    View Specs

A Single Pass Solution To Your Multi-Needs - Vertical tillage systems were created to address the varying needs of farmers. No-till or minimum till farmers found new crop varieties were more difficult to manage in terms of residue. For these farmers, a tool was needed to help breakdown residue without being as aggressive as a disc harrow. The unique Sunflower Saber blade slices through heavy GMO crop residue sizing and mixing it with soil. This speeds its decay and leaves the field level with the remaining material sized for the planter. The ratios of soil to residue are completely determined by the operating depth of the tool. An operating depth of two inches will produce a sized corn crop residue mixed with enough soil to anchor the residue to protect against erosion by wind or water. Increasing the operating dept will lift more soil and enhance the decomposition process.

 Gauge Wheels

Control the leading disc gangs to ensure uniform depth. Wheel pivots are service-free UHMW material and are mounted with parallel linkage to maintain correct wheel alignment.

 Sunflower Saber Blades

The innovative stays-sharp saw-tooth profile of the Sunflower Saber Blade cuts through the toughest crop residue and penetrates hard soils. Each Sunflower Saber blade has twenty-five flutes that are specially designed to fracture and lift the soil. The fluted profile creates a soil mixing action not possible with any other blade. The crop residue is sized, mixed and anchored for faster soil warm-up and resistance to wind and water erosion.

The scalloped edge of the Sunflower Saber blade maintains a very effective cutting edge as the blade ages eliminating the need to mechanically grind or roll the blade to restore performance.

 Features:

The unique disc gang reel is located directly behind the disc gang and provides four important actions:

  • Narrow 7½" Blade Spacing
  • Hydraulic Self-Leveling
  • "Service-Free" UHMW material used throughout

  • Sunflower 6630 Vertical Tillage
  • Sunflower 6630 Vertical Tillage
  • Sunflower 6631 Vertical Tillage
  • Sunflower 6631 Vertical Tillage

 Conditioning Reels

Optional 10 1/4” six blade spiral reels provide the field finish, crushing clods and firming the seedbed. The reels have adjustable spring down-pressure and feature triple-sealed greaseable bearings.
