2026 SUNFLOWER 6631-21NT

SUNFLOWER - 6631-21NT — THREE-SECTION VERTICAL TILLAGE - SEEDBED PREP The 6631 Vertical Tillage Tool has working widths from 20' 2" to 37' 5" and features Saber Blades™, which have a fluted design and low concavity for effective soil lifting all while cutting through and sizing tough crop residue. The next-generation Sunflower 6631 Vertical Tillage Tool uses Saber Blades, which are exclusive to Sunflower. Saber Blades pair a fluted design with a low concavity, creating a soil-lifting action that can’t be duplicated by a conventional spherical disc blade. Each blade has 25 full-depth flutes and features an innovative sawtooth design that maintains its cutting edge, allowing it to cut through tough crop residue throughout the life of the blade. GENTLE ON SOIL, TOUGH ON RESIDUE Not all vertical tillage tools are the same. Innovative and durable, Sunflower vertical tillage tools manage residue and open soil for warming and drying, while minimizing its horizontal movement and reducing compaction layers. The Sunflower 6600 Series Vertical Tillage tools are designed to perform at higher speeds, improving growers’ productivity while delivering excellent residue sizing and mixing, and an outstanding field finish. Unlike other brands, Sunflower vertical tillage tools reel attachments are included in the Sunflower 3-Year Limited Warranty. SUNFLOWER SABER BLADE™ This 22" diameter blade has 25 soil-lifting flutes designed with scallops to maintain an effective cutting edge, acre after acre. C-FLEX™ TRUNNION-MOUNTED BEARINGS The maintenance-free trunnion-mounted bearings are free to realign as the C-Flex standards move when impacted. SPLIT-WING™ TECHNOLOGY Even the widest 35' and 40' models transport at a low 13' 7" height thanks to patented Split-Wing™ technology. In the field, the design positions the wing wheels toward the outside edge of the wing to maintain the correct relationship with the front and rear gangs, ensuring superb performance and a level field. SINGLE-POINT DEPTH CONTROL The single-point depth control is conveniently located at the front of the machine for easy access. Large, easy-to-read markings indicate the direction of movement for adjusting. FRONT-MOUNTED GAUGE WHEELS Front-mounted gauge wheels are a trademark of all flexible Sunflower tools. This important feature prevents the front gangs of the wing frame from gouging, buckling or cutting deeper than the other gangs, promoting a level field. The heavy-duty gauge wheels feature a five-bolt hub and 8x10-ply tire. HYDRAULIC SELF-LEVELING HITCH Level the frame from front to rear with Sunflower’s hydraulic self-leveling hitch. This positive adjustment maintains a preselected setting regardless of the tillage depth. It features heavy-duty compression springs on each side of the pivot to cushion both front and rear gangs, which is important when crossing ditches or rough terrain. MAINTENANCE-FREE UHMW Sunflower equips the 6600 Series Vertical Tillage tools with maintenancefree lift and wing-pivot systems. These systems pivot on UHMW polymer sleeves, eliminating greasing in the lift, wing- and gauge-wheel pivots. SUNFLOWER TILL CONTROL™ Factory-installed option on the 6631 and 6631NT The Sunflower Till Control System brings precise implement control and mapping to tillage operations with accurate in-cab depth adjustment, frame-level monitoring and tillage-pass recording through an ISOBUS terminal task controller in the tractor cab. • Saber Blades pair a fluted design with a low concavity, creating a soil-lifting action that can’t be duplicated by a conventional spherical disc blade. Each blade has 25 full-depth flutes and features an innovative sawtooth design that maintains its cutting edge, allowing it to cut through tough crop residue throughout the life of the blade. • Unlike competitors’ proprietary systems, Till Control works in mixed fleets of various makes of tractors, allowing total flexibility in using Sunflower tools. • Easy-to-use, animated screen graphics guide the operator through calibration, setting of exact tillage depths, controlling the LED implement lighting and more. • Automated settings and depth control ensure consistent tillage passes, even with a less experienced operator in the cab. • Field mapping, acres worked and hours worked are logged and displayed along with service intervals and reminders.
