Agronomic Design™ Features

True-Tandem disk harrow technology combines uniformly distributed pull forces with exclusive Earth Metal blades for optimal tillage performance, even in the roughest of fields. Built on proven Agronomic Design principles, our disk harrows help you effectively manage soil and residue without compaction. Slice through tough residue, uproot root balls and level the soil to create the best possible seedbed for your crop.

Crop Residue Management

  • Control residue size and distribution to promote faster breakdown and nutrient cycling
  • Ultimate disk harrow technology to manage residue from a multitude of crops
  • The Crumbler puts the final touches on the seedbed
  • Precise depth adjustment allows for greater control over soil residue cover at planting to fit a wide range of soil types, topographies and management objectives


Soil Tilth

  • Break through crusty, sealed-over soils to achieve the proper balance of minerals, air and water
  • The 18-degree gang angle matches blade concavity for thorough soil mixing and leveling
  • Promote a better seedbed finish without the excessive compaction typical of heavier disks
  • Helps reduce residue hair-pinning, resulting in better seed-to-soil contact and stand establishment


Seedbed Conditioning

  • Put the finishing touches on fields by sizing clods and increasing the soil’s contact with residue for maximum decomposition
  • Provide a uniform seedbed depth and temperature, contributing to early, even plant emergence


Durable True-Tandem Frame

Improve balance and stability in the field with the True-Tandem frame design. The combination of mirror-matched gangs and a rugged, low-maintenance pull-through frame eliminate drift and accommodate higher ground speeds compared with the traditional double-offset frame. LED lights and a high-quality powder coat paint finish keep you in the field longer and your equipment looking good for years to come.

Mainframe and Wings

  • Provide exceptional center of gravity and balance
  • Designed with gusset plates to maximize strength and stress distribution
  • Deliver more uniform weight per blade
  • Increased length over competitive equipment improves overall balance and fore and aft leveling
  • Overlapping weld design and welded cylinders improve durability while reducing maintenance and the chance of leaking


Greaseless Bearings

  • Featured on wing pivots, rockshafts and the Crumbler
  • Reduces routine maintenance, keeping you in the field longer


Durable Design Attributes

  • LED lights are brighter and longer-lasting than incandescent lamps
  • The Class 3 powder coat paint finish retains color longer and is more scratch resistant

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
  • 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
