AGCO added new Sunflower brand models to two of its tillage implement lines in August —the 1436SW (the SW refers to the split wing frame design) tandem disc harrow and the 6650 vertical tillage tool. AGCO gave farmers their first look at them during the U.S. Farm Progress Show in the early fall.
The new model 6650-48 pushes the maximum working with to 47 feet, 11 inches in the 6650 vertical tillage line.
“Sunflower is excited to offer the 6650-48 vertical tillage tool to today’s conservation-minded farmers,” says Larry Kuster, AGCO senior marketing specialist for tillage. “It provides a significant boost in productivity by harnessing the potential of high-horsepower tractors with the ability to cover more than 38 acres an hour.”
The 6650 Series tools use the brand’s large-diameter Saber disc blades in gangs set at an 18 degree angle.
The 6650-48 has a five-section frame that folds to a transport width of just over 18 feet. The frame is made from 6×6-inch square tubing with a 3/8-inch thickness for strength and to give the implement its weight. When unfolded, hydraulic cylinders lock the wings in place and permit pivoting only at the lower hinges near the gangs, which allows the implement to more closely follow field contours.
The 1436SW Series of tandem disc harrows sees the addition of two new working widths, the 33 foot, three inch 1436-33SW and the wider 38 foot 1436-38SW. 1436SW implements weigh up to 600 pounds per working-width foot, allowing them to penetrate firm soils.
This line uses a 20-degree gang angle and full concavity disc blades to more aggressively cut and bury field residue. Both front and rear gangs are offset to allow the front gang to cut the entire working width. The rear gang creates a feathering effect that prevents ridge and valley profiles in the wake of the machine. Both sets of gangs ride on C-Flex bearing standards to absorb shocks encountered when striking field obstacles.
“They mix residue and topsoil to provide an ideal environment for microbial decomposition of the stalks,” says Kuster. “With today’s tough stalks, increased compaction in many fields, and herbicide-resistant weeds, a high-performing tillage tool is more important than ever.”
