Case IH is expanding its 4400 Series corn header line-up with a new lightweight, narrow-row header designed to help farmers pick cleaner, harvest faster, and improve handling of down corn.
The new models have been completely redesigned — from the row unit and frame, to the gear box and power drive — to meet the needs of farmers who plant on 20- and 22-inch rows, explains Kelly Kravig, Case IH Axial-Flow combines and corn headers marketing manager. Case IH unveiled the new header last month at the National Farm Machinery Show in Louisville, Kentucky.
in this video, Kravig explains the company took a “clean-sheet approach” when designing the header and focused improvements on five key performance areas. These include: picking cleaner to reduce material other than grain coming into the corn head and combine; increasing picking speeds by boosting corn head capacity; saving more grain with a redesigned corn head that gently transitions grain from the head to the combine; picking up down corn with row units that sweep the stalk into the stalk roll; and improving combine flotation with reduced overall header weight.
Available in 20- and 22-inch spacing, new narrow row chopping and non-chopping configuration options fit any residue management system, and the lightweight header — up to 2,000 lbs less than competitive models — floats just above the ground to reduce compaction.
Power flow has been completely redesigned. For the first time, power is driven from the gear boxes in the centre of the header and split equally to the right and left side. From there, separate drive lines power the row units and choppers. Several other features contribute to the header’s grain-saving capabilities. These include:
- New flip-up tall-corn attachments help prevent loss of corn ears over the ends of headers when harvesting in tall stands of corn.
- Updated stalk roll spiral patterns handle a wider range of stalk diameters and stalk health.
- Divider profile and hood design aid in smoother crop flow.
- Row guide sensors help the row unit stay centred on the rows, reducing overall ear bounce and grain loss.
