What the 6631 Vertical Tillage is used for
The 6631 is used for shallow fall or spring vertical tillage, particularly where crop residue needs to be cut and distributed without aggressive soil inversion. The blades and rear conditioning reel help size residue and firm or level the topsoil. It is generally a secondary or residue-management tool rather than a deep primary-tillage implement.
Why the Sunflower 6631 Vertical Tillage stands out
Narrow blade spacing provides continuous cutting across the tool width. The three-section frame uses hydraulic self-leveling, and the conditioning reel follows the blades to refine the surface finish.
Buying a used Sunflower 6631 Vertical Tillage
Inspect Saber blades for reduced diameter, cracks, and uneven wear. Check gang bearings, gang hardware, reel bearings, hydraulic hoses, and self-leveling linkage for play or leakage. Look carefully at wing hinges, transport locks, tires, and wheel bearings.
