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.

Seedbed Conditioning
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.

Durable Design Attributes
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.
