Sunflower 4213 / 4233 Coulter Chisels: 8' 9" - 28' 9"    View Specs

Eliminate soil compaction while managing crop residue with Sunflower 4200 series coulter chisels which completely fracture hardpans and eliminate soil compaction to a depth of 12". Equip the heavy chisel standards with twisted points and together with the large diameter coulters spaced every 7½" the crop residue is sized and incorporated into the soil for rapid decomposition and nutrient recovery.

 Optional Offset Shank Modules

These modules can be added to the rear bar of the machine, providing even more clearance for demanding residue.

 Standard Walking Tandems

All greasing is eliminated on the heavy-duty wing hinges with the maintenance-free UHMW plastic sleeves.

 Shank Opions

The rigid shearbolt or auto-reset shanks completely fracture hardpans to a depth of 12" to 14", breaking up soil compaction that a wider-spaced shank arrangement would miss. Sunflower 4200 Series Shank Options

 Heavy-Duty Trash Bars

Heavy-duty 3" wide channel iron trash bars are mounted between each coulter blade to help keep the gangs clear of residue and dirt buildup.

 C-Flex™ Coulter Gang Hangers

Shock absorbing mounts protect against field obstructions. Spring end collars help ensure the gang stays properly torqued. Coulter gangs eliminate plugging or need for shredding or discing before ripping.

 Single or Double Clevis Adjustable Hitch

Either a single or double clevis adjustable hitch is available to allow front-to-rear leveling of the machine.

 Heavy-Duty Separating Spools

Each spool weighs 50 lbs, enough weight to slice through heavy residue. Gangs feature two rephasing lift hydraulic cylinders (protected by shock-absorbing mounts) to control the front gang depths with on-the-go adjustments.

 Heavy-Duty Frame

An all welded 4" x 6" x 3/8" frame with special formed gussets in all high stress areas. UHMW technology around the rock shafts means no greasing needed and less parts wear.

 Well Braced Over The Tip Hitch

All coulter chisels are fitted with overhead truss hitches providing down pressure to ensure no frame bounce.

 20" Coulter Blades

Spaced on 7½" centers with long-life, trunnion-type bearings. Pre-fracture the soil and size residue ahead of 15" spaced chisel shanks at 12"-14" maximum depth. Equipped with 1¾" gang shafts.
