Sunflower 1550 Disc Harrow: 47' and 50'   View Specs

The 1550 big acre eating appetite manages over thirty acres per hour with five section flexibility. Over 600 pounds per foot equals 230 plus pounds per blade to cut through the toughest crop residue and penetrate the hardest of soils. Duplex wing hinges provide the wings with two pivot points. The lower pivot, closer to the blades, allows more down flex (10°) than competitive five section tools (5° to 7˚°). In addition, it maintains proper blade spacing. The upper pivot provides the offset needed to fold the wing frames for transport.

 Duplex Wing Hinges

Eight tires on four sets of walking tandems are on the ground at all times during transport for added safety and stability. This is a real advantage when compared to dual tires on competitive models. Large 2¼" diameter spindles and eight bolt hubs and wheels ensure years of dependable service.

 Narrow Transport

Moving from field to field is easy and stress free thanks to the narrow width and low transport dimensions of the SF1550 series tandem disc harrows.

 Safe Transport

The 1550 is further augmented by another Sunflower exclusive: "Walking Triples". This revolutionary design puts three tires in a walk-over tandem set rather than two. The Walking Triple design increases the load capacity fifty percent over a two tire carriage and provides excellent stability on the road.

 Maintenance-Free Gauge Wheels

Disc gang control is augmented by a gauge wheel on each wing.The gauge wheels are designed into the disc harrow and are located near the outside ends of the disc gangs for optimum gang control. Vertical adjustments are made with parallel linkage keeping constant the angle of the wheel arm to the soil. The gauge wheels pivot on maintenance free UHMW bushings.

 More Weight Carrying Capacity

Walking Triple Tandems (patent pending) located in the center section have 50% more weight carrying capacity than conventional walking tandems. A total of fourteen tires supply unequaled flotation and implement carrying capacities.

 Aggressive Gang Angles

Gang angles of 18°, exceptional weight of 665 pounds per foot, and full concavity (24") disc blades equip the SF1550 to work through the toughest crop residue and hard soils to manage crop residue or build a seedbed at thirty acres per hour.
