What the 1435 Disk Harrow is used for

The 1435 is used to chop and incorporate residue, loosen the upper soil layer, and level a field after harvest or prior to planting. It can serve as primary tillage in lighter conditions or as a secondary pass after deeper tillage. A rear harrow attachment can further distribute residue and smooth the surface.

Why the Sunflower 1435 Disk Harrow stands out

The flexible three-section layout follows field contours better than a rigid disk of similar width. Its tandem gangs use full-concavity blades for soil mixing and residue incorporation, while the heavy frame provides blade weight for penetration.

Buying a used Sunflower 1435 Disk Harrow

Measure several blade diameters because uneven blade wear can cause poor penetration and uneven gang performance. Check gang bearings, gang bolts, spool wear, axle threads, and scraper condition. Inspect hinges, hydraulic fold cylinders, wheel bearings, tires, and frame welds before buying.
