The Superharrow 3568 from Summers features an eight-bar design, allowing it to produce 60% more work compared to harrows with only five bars. With 0.5 inch diameter teeth and eight full rows of harrows, the Superharrow 3568 breaks up more residue and clumps in a single pass, allowing a greater surface area to be exposed for expedited decomposition.

Standard features of the Superharrow 3568 include a heavy-duty drawbar, auto-folding pull cables, hydraulic depth adjustment, a top-mounted torsion bar and adjustable tooth angle with independent adjustment of the front bar. The unit is available in 36, 48, 60, 72 and 84 foot widths.
