6631 Three-Section Vertical Tillage

6631-36

Overview:

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 that creates a soil lifting action that can’t be duplicated by a conventional spherical disc blade. Each blade has twenty-five full depth flutes and features an innovative saw tooth design that maintains its cutting edge, allowing it to cut through tough crop residue throughout the life of the blade. Sunflower Saber Blades keep cutting heavy residue long after the competitor’s blades have dulled beyond effectiveness.

Features

SUNFLOWER SABER BLADE

This 22-inch-diameter blade has 25 soil-lifting flutes designed with scallops to maintain an effective cutting edge acre after acre. No grinding or rolling is necessary

TRUNNION-MOUNTED BEARINGS

The trunnion bearing features triple-lip seals that cannot be damaged by daily greasing and metal washers that protect the seals from being damaged by stocks or material wrapping around the gang shaft. As the C-Flex bearing standards move, the gang bearings constantly realign. There is never any wear between the bearing and the housing, always creating positive lubrication as a result.

C-FLEX BEARING STANDARDS

Sunflower’s trunnion bearings provide positive alignment, eliminate side-loading of the bearings and the housing to ensure positive lubrication. As the C-Flex bearing standards move, the gang bearings have to constantly realign.

SINGLE-POINT DEPTH CONTROL

Single-point depth control is conveniently located at the front of the machine for easy access. Large, easily read markings indicate the direction of movement for adjusting.

FRONT-MOUNTED GAUGE WHEELS

A trademark on all flexible Sunflower tools is front-mounted gauge wheels. This important feature prevents the front gangs of the wing frame from gouging, buckling or cutting deeper than the other gangs, promoting a level, ridge- or furrow-free field. The heavy-duty gauge wheels feature a five-bolt hub and 8x10 ply tire.

HYDRAULIC SELF-LEVELING HITCH

Level the disc 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 6630s are equipped with maintenance-free lift and wing pivot systems. These systems pivot on UHMW polymer sleeves, eliminating greasing in the lift, wing and gauge wheel pivots.
