Corn head Drago 2

for combine harvestersrotaryuniversal

Overview
Olimac Drago2 is a corn header engineered for total harvesting with minimal kernel and ear losses. It integrates automatic self-adjusting deck plates, extended stalk rollers and an optional rotary-blade stalk chopper. Available in configurations from 4 to 24 rows, fixed or foldable, it can be adapted to most combine harvesters and self-propelled shredders.

Key advantages

• Automatic self-adjusting deck plates: independent continuous adjustment per row eliminates manual settings and reduces losses.
• Longer stalk rollers: lower peripheral speed for gentler ear separation and improved stalk pressing to minimize kernel loss.
• Optional rotary-blade stalk chopper: low power requirement; chops stalks to leave the field plough-ready.
• Low-profile design and reduced working angle (~18°): better penetration for lodged corn and reduced ear bounce.
• Foldable from the operator platform: reduced transport width (approx. 3–3.20 m) while maintaining visibility.
• Universal mounting: compatible with most combine harvester brands and self-propelled shredders.

Transmissions and protection

• Three transmission options: A) internal transmission with oil-drop lubrication; B) oil-bathed external transmission with intermediate joint allowing folding without removing the driveshaft; C) oil-bathed external transmission optimized for hilly terrain.
• Each row uses oil-bathed mechanical gearboxes and hardened steel bevel gear sets.
• Slip clutch protection on each row-group to safeguard transmission components.

Construction and components

• Reinforced steel gathering chains with hard-chrome pins and spring self-tensioning to absorb mechanical stress.
• Knife-type stalk rollers with interchangeable tungsten-carbide blades for durable cutting performance.
• Full-length weed/knife guards to prevent wrapping and blockages.
• Low-profile frame and accessible layout: rapid quick-release mechanisms grant fast access to transmission elements without tools for maintenance operations.

Options and accessories

• Built-in rotary-blade stalk chopper (optional).
• Ear stopping rubbers for uneven ground or variable crop heights.
• Stalk pressing kit for combine tyre protection.
• Sensor kit for automatic bar leveling.
• Light bar for road transport.
• Sunflower kit: anti-fall grid and stalk-cutting rotor.
• Directional change gearbox and stalk conveyor on the chopping device.

Customisation and support
Olimac provides a dedicated customisation service to develop special configurations on request. Original spare parts and a worldwide authorised service network ensure safe operation and rapid technical support.
