Sunflower 1810 & 1830 Series Offset Disc Harrows: 14' 4" & 39'   View Specs

Big Blades for Aggressive Tillage! This series of heavy tandems is designed to penetrate hard packed soils and thickly matted crop residue to perform the primary tillage function. Larger blades, wider blade spacings and massive frames combine to produce industry leading weights per blade specifications. Available in widths from 14' to 18' in rigid frames or three section flexibility from 22' to 39' to maximize productivity of the largest of tractors. There’s an 1800 series tool to match your tractor.

 Heavy-Duty Frames

The SF1800 Series frames are constructed of high strength 4" x 8" x 3/8" steel tube to withstand the high stress of aggressive tillage. It is cross braced and gusseted for added strength and trouble free service.

 Rigid or Spring Cushion Gangs

With 5/16" thick plain or notched disc blades. Available in 28" or 30" diameters the blade spacings are 11" or 13" depending on the model selected. The gangs are supported by 1 15/16" shafts revolving on 214 re-lube gang ball bearings fitted with lubrication fittings. The hardened steel scrapers provide a continuous cleaning action.

 Staggered Overlapping Disc Gangs

Staggered overlapping disc gangs is one of the keys to level discing. The overlapped placement of the front gangs cuts all of the ground cleanly while the staggered rear gangs throw the soil back in a criss-cross pattern. This arrangement eliminates the need for a chisel shank or bulk buster typically required in the center and behind the front gangs of conventional tandems. Even more importantly, the Sunflower combination eliminates ridging in the center, another problem common with conventional tandem discs.
