Sunflower Launches New Era in Tillage

Sunflower CartSunflower®, the leading tillage line from AGCO Corporation (NYSE:AGCO), has introduced the new SF6830 high-speed rotary finisher and SF6610 vertical tillage tool, as well as the SF4630-09 to Sunflower’s line of SF4600 Series of disk rippers. The revolutionary SF6830 high-speed rotary finisher and the SF4630-09 disk ripper combine multiple tasks into one-pass systems, while the SF6610 rounds out Sunflower’s Vertical Tillage offering providing a vertical tillage tool to fit every size farm.

The SF4630-09 disk ripper and the SF6830 high-speed rotary finisher can be seen at the AGCO lot during the Farm Progress Show in Decatur, Illinois, Sept. 1–3.

SF6830 Sunflower’s Latest High-Speed Rotary Finisher

“Sunflower is launching a new era in tillage with the SF6800 Series, a tillage tool specifically designed to utilize a new concept in seedbed preparation,” says Larry Kuster, AGCO senior product marketing specialist.

The SF6830 Series provides operators the high-speed, high-residue flow capabilities unattainable with traditional shank-equipped finishers and cultivators. The heavy-duty optimum design of the SF6830 Series is completely void of sweeps, combining four types of rolling-ground engaging tools into a three-step process.

“The SF6830 Series utilizes a gang of 20-inch, low-concavity blades set at an 8-degree angle to provide just the right amount of lateral soil movement to level soil and anchor residue,” continues Mr. Kuster.

Placed behind those blades, the SF6830 Series has sealed, service-free disc gang reels that turn at twice the speed of the disc blades. This allows the gang reels to aggressively break up clots and root crowns, while limiting excess lateral movement of the soil, preventing the soil ridging normally associated with single-gang tillage tools. Wavy coulter blades are positioned in a gang behind the blades and reels to continue sizing crop residue and to fracture the soil to provide avenues for root development.

The final element of the SF6830 Series is two intermeshed gangs of Sunflower’s exclusive Rotary Spider Tines. These tines are designed to ensure that the soil is leveled and that crop residue is equally mixed across the entire width of the tool. The Rotary Spider Tines sculpt the seedbed floor flat, as they lift the soil and blend it with crop residue.

Because all of the ground-engaging tools utilized in the SF6830 are of the rolling type, the possibility of the unit plugging-up is virtually eliminated. The SF6830 Series is a low-maintenance, high-speed rotary finisher.

New 6610 Vertical Tillage Tool

The Sunflower 6610 vertical tillage tool provides operators the same features and high level of performance of the larger Sunflower vertical tillage tools but in a smaller package. The SF6610 is available in two operating widths — 11 and 14 feet. These new, smaller, single-section tools join the nine larger models of the SF6600 Series for a total of 11 sizes in “true cutting widths” from 10 feet, 7 inches, to 48 feet, 7 inches.

The SF6610 is equipped with tandem axles, large tires and a strong frame, accommodating the heavy finishing attachments used in vertical tillage. Equipped with Sunflower Saber Blades™, and the proven overlapping/staggered gang design. The SF6610 produces an excellent seedbed avoiding the ridged and valleyed seedbed profile produced by other tools.

The SF6610 is capable of cutting through the toughest residue and penetrating the hardest soils to fulfill any operator’s needs. The SF6610 can be used multi-seasonally, from opening a cold, damp field in the spring to performing residue management duties in the fall.

Like the other models in the SF6600 Series, the SF6610 is a highly capable, long-lasting, low-maintenance vertical tillage tool. The standard walking tandem axles come with triple-sealed bolt-in spindles that cannot be damaged by over-greasing, offset C-Flex™ bearing standards and a maintenance-free lift system with ultra-high molecular weight (UHMW) plastic bearings. The reduction in daily maintenance results in more time in the field.

Sunflower 4630-09 Disk Ripper

The SF4630-09 is designed to combine three important post-harvest tillage tasks in one pass, capable of crop residue management, eradication of soil compaction and seedbed preparation. The SF4630-09 is a narrow-transport, folding frame, nine-shank disc ripper equipped with walking tandem axles between large 385/65R by 22.50 tires. The SF4630-09 frame is constructed of high-strength, 4-inch by 8-inch by 3/8-inch steel tubing and is engineered and manufactured to withstand the high stress of aggressive deep combination tillage.

The SF4600 Series is available in models ranging from seven to 13 shanks, with three models in folding configurations.

Everything about the SF4630-09 disk ripper is designed to maximize the crop residue decomposition process. The large, individually mounted 28-inch diameter disc blades are spaced 7.5 inches apart in two rows. Operators can choose between the extremely aggressive 28-inch Saber Blade or a conventional 28-inch smooth-edge blade; both styles operate at working depths ranging from 0 to 8 inches. The tandem gang design is extraordinary at sizing and incorporating crop material into smaller, faster-decaying pieces, and the C-Spring individual blade mounting produces optimal material flow and rock protection.

SF4630-09 gang depth is fingertip-controlled from the cab and adjusted independently of the ripper shanks, achieving the perfect balance between two components.

The heavy point load and true auto-reset designed service free parabolic shanks of the SF4600 Series maintain the correct point position even at maximum depth.

The SF4360-09 is available with four optional finishing attachments, each tailored to a different soil type and crop residue. Operators can choose between the heavy-duty coil tine harrow, the two-bar heavy-duty coil tine harrow and reel, the five-spike tooth drag harrow, and the two-bar heavy-duty coil tine harrow and hydraulic controlled reel, giving operators the ability to choose a finishing attachment best suited to the final condition of their soil.
