Sunflower's new 6631 Series vertical tillage

Agriculture.com Staff 08/21/2012 @ 9:26am

AGCO has introduced the new Sunflower 6631-35 and 6631-40 vertical tillage tools. The latest addition to the 6600 Series, these new tools have the width to meet early spring tillage needs of large farms and are designed to create a consistent seedbed across the entire width of the machine. With the Sunflower-exclusive Split-Wing design featuring locking wing extensions, these tools offer strength and stability, but fold to a compact package for transport.

The tough vertical tillage tools easily shred and mix tough crop residue to enhance warming of cold, wet soils so planting can begin earlier. Available in 35- and 40-foot working widths, they allow farmers to cover ground efficiently while creating a soil surface that reduces wind and water erosion, and a consistent seedbed that enhances uniform emergence and early crop growth.

“Farmers will find a number of unique features in the new Sunflower 6631 vertical tillage tools that not only allow the machines to size and mix residue very effectively, but that also ensure long life and consistent performance in the field,” says Tom Draper, Sunflower seeding and tillage product marketing manager. “They were intentionally designed with a low horsepower-per-foot requirement to help farmers cover more acres with less fuel. That increases return on investment in both time and dollars.” In addition, each machine is backed by the Sunflower three-year limited warranty.

Superior seedbeds 

All Sunflower vertical tillage tools are equipped with 22-inch (558.8 mm) scalloped, low-concavity Sunflower-exclusive Saber Blade™ disc blades, which are mounted at 7.5-inch (191 mm) spacings to deliver consistent, ridge-free seedbeds. 

“Saber Blade discs are fluted the full cutting depth of the blade. This helps maintain an aggressive cutting edge even as they wear, which results in longer blade life,” notes Draper. “With the disc blades mounted in an overlapping disc-gang design, the front gang clear-cuts the entire machine width, which prevents the ridging typical of other designs. The staggered rear gang then helps smooth the soil, to improve seedbed consistency and quality.”

By lengthening the machine’s frame, Sunflower engineers also enhanced its ability to cut through and size very heavy residue without plugging. Three options in finishing reels are available to provide the final touch that breaks clods, disperses root crowns and lightly compresses the soil surface to help conserve moisture. Choose from 11-inch and 14-inch flat-blade and 14-inch round-bar reels, to match the needs of local field conditions. 

Tough, low maintenance, easy-to-use 

The heavy main frame of 4- x 6- x 3/8-inch stringers front to rear has the strength expected from Sunflower and will meet the demands of tough tillage conditions. Low-maintenance features include ultra-high molecular-weight (UHMW) plastic bearings and bushings, to eliminate metal-to-metal contact and wear without the time and expense of grease and regular service.
