    Leveling & Depth Control

    Level the Growing Field

    Work the soil you want to work. The lineup of True-Tandem disk harrows engages soil to your intended depth without disrupting soil density below the operating depth. It’s a system that’s proven to provide more consistency, even as soil types change across the field. And thanks to an intuitive depth adjustment system, you easily can adjust depth control and leveling to meet the needs of your conditions and fields.
    • Single-point Hydraulic Depth Control

      • Easily adjust operating depth with a single hand crank conveniently located at the front of the machine
      • Helps adjust to adverse conditions, such as wet, muddy soil
      • The system holds a constant blade operating depth to provide a uniform seedbed depth temperature, contributing to early, even plant emergence
    • Fore and Aft Leveling

      • Increased wingspan improves overall balance and fore and aft leveling
      • Optional hydraulic front-to-back leveling allows quick operator reaction to changes in field conditions
      • View the gauge from the cab to easily return to your pre-adjusted position

    Gang Assembly

    Durability and Low Maintenance For Any Field

    The True-Tandem gang assembly precisely matches front and rear gang blades for maximum productivity and a smooth seedbed, regardless of field conditions. The 18-degree gang angle paired with the concavity and crimped center of each blade gives you even cutting and mixing action. With more durability and low maintenance features, the True-Tandem disk harrow will get you in and out of the field and ready to plant.
    • Bearing Options

      • Flange-style bearing works well in fields with few rocks and debris
      • For areas with rocks and debris, the cushion gang option holds the arbor bolt firm, yet allows the joint to rotate freely through rough terrain for a high-quality finish
      • For extreme soil conditions and rocky areas, additional heavy-duty bearings and gang hangers strengthen and support longer gang segments (31 ft. and 34 ft. only)
