2026 SUNFLOWER 6433-40

SUNFLOWER - 6433-40 — SPLIT-WING LAND FINISHERS INCREASE YOUR EFFICIENCY WHILE REDUCING INPUT COSTS Performing multiple tillage operations in a single pass saves you trips across the field and reduces input costs. The model 6433 Land Finisher has working widths from 36’ 9” to 42’ 9”, letting you perform multiple tillage operations in one pass. This increases efficiency and reduces costs in fuel, tractor wear, multiple implements, and anti-compaction efforts. FEATURES • Split-wing folding: three-section field performance with five-section folding for low height and narrow transport dimensions. • Hydraulic disc gang adjustment (optional): from the tractor cab, adjust the disc gangs from 1" below the sweep to 5" above. • 1 ¾" diameter gang shafts ensure precise alignment of the entire disc gang. • Disc gangs feature 20" diameter, 1 5/16" low concavity blades. • Choose spring-tension (190-pound) or two-piece S-tine shanks (160-pound). THE SINGLE-PASS SOLUTION FOR MULTIPLE NEEDS Sunflower’s 6000 Series finishers produce excellent high-quality seedbeds, delivering multi-step residue sizing and soil leveling, mixing and conditioning to give your crop the best soil environment possible. The Land Finishers accomplish the task with a combination of blades, sweeps and conditioning attachment to define the seed zone by sizing residue, leveling, lifting and mixing soil. UNIQUE DISC GANG REEL The unique disc gang reel is located directly behind the disc gang and provides four important actions: • Pulverizes soils and clods • Thoroughly incorporates chemicals • Vigorously mixes soil and residue • Prevents lateral movement of the soil and eliminates ridging HEAVY-DUTY DISC GANG ASSEMBLIES • 1 ¾" diameter alloy steel gang shafts • 20", 1.32" low concavity disc blades, either six gauge or four gauge • 7 1/2" disc gang spacing with steel spools • Triple-sealed self-aligning maintenance-free disc gang bearings DISC GANG PLACEMENT The disc gangs direct the soil into the gang reels. The gang reels located immediately behind the disc gangs level the surface profile by preventing the lateral movement of soil that would create ridges and valleys. ADJUSTABLE DISC GANG DEPTH The gangs are adjustable from 1" below to 5" above the cultivator sweeps. Adjustment is accomplished with either the manual or hydraulically adjustable feature. SPRING-CUSHIONED DISC GANGS The disc gangs are equipped with heavy-duty spring-cushioned mounts to protect them from obstructions such as rocks and stumps. SPRING-CUSHION SHANKS With 25" of under-frame clearance, the 5/8" thick, 190-pound-point-load shanks on a five-bar cultivator placement provide optimum trash flow. S-TINE SHANKS S-Tine 160-pound-point-load shanks are also available if rocks and stones are not present and the heavier spring-tension shanks are not necessary.
