ARRO (Alternate Rotary Rowcrop Option) patented kits from Kopper Kutter convert OEM cornheads to enable "cutting" crops such as sorghum, milo, sunflowers, millet and many other crops. Kopper Kutter kits are intended to repurpose OEM cornhead that have worn out stalk rolls, worn trash knives and worn deck plates. These parts are removed and discarded.

The ARRO kits come with new sculpted deck plates, profile chain guides, and integrated sprockets, bearings and innovated dual disk cutting blades. The converted OEM cornheads retain the reliability of enclosed drives and gearcases, individual row unit slip clutches, poly points and center shields, auto height control systems, extremity lighting and maximum combine to header compatibility and safety.
