features and benefits

sup 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.

VRT 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.

VRT Top-Mounted Torsion Bar

Our exclusive top-mounted torsion bar springs provide a streamlined design for optimum residue clearance.

flotation 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.

Flotation Tires

The standard 11 LRF x 15” tires on the drawbar can be replaced with optional 31 x 13.5” tires for increased flotation.
