YIELD FEATURES
The heart of kernel capture technology™
NO OTHER CORN HEAD IN THE FIELD IS ENGINEERED TO CAPTURE MORE YIELD.
Automatic Self-Adjusting Deck Plates
Every 1/8” misadjustment gap between the stalks and deck plates accounts for up to four bushels lost per acre. And considering today’s higher plant populations, the increasing amount of plant material corn heads process and corn hybrids that dry down in the field and cause more butt-shelling, the potential yield loss steadily increases, too. On every farm, at every harvest, the Drago Automatic Self-Adjusting Deck Plates prove their value in capturing the corn you’ve grown.
QuadSuspension™ Deck Plate Shocks
The exceptional speed at which knife rollers work to pull down stalks results in a violent ear impact on plates. To mitigate this impact, the Drago GT introduced yet another industry first — QuadSuspension™ — integrated, impact-absorbing “ear shocks” that can significantly reduce butt-shelling and the resulting yield loss.
LONGER KNIFE ROLLERS
At 22.5 inches, the Drago GT features the longest knife rollers in the industry.
Slower Tip Speed
Having the longest knife roller with a smaller diameter reduces tip speed for less ear bounce, greater ear retention and reduced butt-shelling.
Reducing Ear Loss
A knife-to-knife design pinches, pulls and opens up — allowing plants to move farther back into the corn head before the ear is removed.
Nose Cone Bearings
Drago not only supports its knife rollers out front, but has two bearings and a grease bank built right into the nose cone itself. A dirt barrier is milled in to protect seals and bearings when tips are closer to the soil, as in downed-corn situations.
Knife Roller Supports
Drago builds bracket supports to keep knife rollers from spreading and breaking.
DRIVE DESIGN FEATURES
BUILT TO WORK. MADE TO LAST.
PERFORMANCE AND DURABLE DESIGN.
When you build a corn head for harvest efficiency, you also know the importance of a timely harvest. We know there is never a good time for a corn head not to perform, which is why Drago corn heads are engineered for harvest dependability.
ENDURA DRIVETM
Endura Drive™ is the first chainless design in all corn head sizes. Gears transfer more power from the combine to the row unit for maximum efficiency — a simple, durable and efficient delivery of power.
AUGER DRIVE
As part of the Endura Drive™ system, the Drago GT gear-driven auger minimizes maintenance and keeps the auger-drive clean and free of debris. This is the industry’s first chainless-drive available for every row configuration.
INLINE POWER
Endura Drive™ design allows power to be driven inline through the row units, eliminating two gears per row vs. the competition, for higher efficiency. Drive shafts are connected with removable self-engaging couplers if a single row unit repair is ever needed.
INDEPENDENT COMPONENT PROTECTION
Each major component of the Drago GT is protected from field hazards, from our gear-driven auger to the Precise Clutch Technology™ protecting knife rollers, gathering chain drives and choppers. This Drago design delivers maximum protection to equipment and added peace of mind to the operators.
PRECISE CLUTCH TECHNOLOGY™
Olimac is the first to integrate a radial slip clutch design with four different operations, internally, within the row unit. Other corn head brands use a “one-clutch-fits-all” approach with one setting for the highest load on the row unit and leaving other components unprotected. In the Drago GT, each clutch has its own precise setting for both gathering chain drives, knife rollers and chopper gearbox – completely sealed from external elements, bathed in oil, and delivering significantly better protection.
INDUSTRY-FIRST SPIRAL-CUT GEARS
Endura Drive™ design allows power to be driven inline through the row units, eliminating two gears per row vs. the competition, for higher efficiency. Drive shafts are connected with removable self-engaging couplers if a single row unit repair is ever needed.
BONNET LIFT
After the T-handle is pulled, a gas strut lifts and holds the bonnet and snout up and out of the way for easier access.
SEIZE-FREE TENSIONER
Drago’s gathering chain tensioner can be greased, which acts as a filler and seals out dirt and debris. Allowing the tensioner to work freely all season long increases the life of the gathering chain. It can be easily removed with four bolts.
CHOPPING FEATURES
YIELD FIRST CHOPPING
NO OTHER CORN HEAD PROVIDES MORE FLEXIBLE CHOPPING OPTIONS.
TWIN CHOP+
BALANCED BENEFITS WITH EASE OF MAINTENANCE
Drago’s “Yield First” design provides an optimum balance of maximized harvesting and quality chopping in both optimal and tough conditions. Chopper maintenance is quite simple. Drago knives have a tungsten carbide edge and are easily reversed.
COUNTER-CUTS FOR MORE THAN JUST LENGTH
The Twin Chop+ advantage can be seen in its counter-blade rotations — sizing and splintering stalks from one blade to another, delivering faster and more complete breakdown after harvest.
TWIN CHOP+ PROVIDES EXCEPTIONAL SIZING
The Drago GT’s new Twin Chop+ option is so good, knife rollers can still run slow for maximum yield retention. Delivers continuous chopping of stalks as they travel back and down through the entire length of the knife roller.
DOUBLE THE CHOP WITHOUT DOUBLING THE HORSEPOWER
Twin Chop+ features a highly efficient single gearbox design that delivers power straight forward — no 90-degree bevel gears after power is delivered to the gearbox.chopping of stalks as they travel back and down through the entire length of the knife roller.
SINGLE CHOP
SINGLE CHOP FOR FLEXIBLE NEEDS
Drago GT offers a single chop option for standard sizing. Plus, an on-and-off engagement lever that provides field-to-field residue management flexibility
CONTROLLED UP-FRONT CHOPPING
The Drago GT chopping systems are designed to deliver the chop quality you want and still retain yield. Unlike other brands, Drago chopping blades are placed just behind the knife rollers so they don’t strike the plant until it is under control from the pinch received from the rollers. This is crucial so that no matter what conditions you face – from leaning to down corn – yield is not sacrificed.
