Originally developed in the 1960s as the Herman Harrow, the Superharrow 3960 is the heaviest, most aggressive series of harrows from Summers. It offers 26-inch-long, 9/16-inch-diamater teeth that are oil tempered and spring-mounted with 2.4-inch effective spacing and 16-inch spacing between bars. Each section is 6 feet wide for superior penetration and increased ability to follow ground contours. Applications: seedbed preparation, spring tillage, spring residue management, fall residue management, soil conditioning |

Heavy Duty Drawbar Our 8-by-8-inch drawbar tube is bigger and stronger than anything else available. It provides maximum strength for pulling the harrow. |
Auto-Folding Pull Cables Simply put, cables are better than pull tubes when it comes to harrow design. That’s because cables allow easier unfolding from transport to field position. And they’re engineered to accommodate the rearward stress that’s placed on the inside wing of a harrow during a tight turn. Even more, the Summers auto-folding cable design has a positive lock system and a back-up feature that allows the operator to reverse while the harrow is unfolded to reach isolated areas and tight corners. |
Hydraulic Depth Adjustment Hydraulic cylinders on the cart and wing wheels allow on-the-go adjustment of down pressure to accommodate different soil conditions and residue. The system provides even down pressure across all harrow bars and offers exceptional ground following ability. The streamlined wing height adjustment design allows teeth to cover the wheel tracks. |
Top-Mounted Torsion Bar Our exclusive top-mounted torsion bar springs provide a streamlined design for optimum residue clearance. |
Adjustable Tooth Angle A spring-loaded adjustment lever allows the operator to angle the teeth up to 45 degrees from vertical position. The front bar adjusts independently of the other four, allowing the front bar to work more aggressively, while the rest of the section clears the residue. |
Split Hinged Wing 60- to 84-foot models are available with split hinged wings. |
Hydraulic Tooth Angle Adjustment This option allows the operator to adjust the tooth angle on the go. |
