Rotary Corn Header 


Simple, versatile and productive

The only 4-row (10ft) corn head for pull-type forage harvesters on the market, the F61 header is in a class of its own.


Exploit all the available tractor power and reduce time in the field. Less distance traveled and lower harvesting speed will have a significant impact on the fuel consumption per ton of silage harvested.


Perfect Cut


The rotary blades are driven by v-belts and turn the opposite direction of the drums. This design eliminates vibrations. The six blade sections, per disk, are made or harden spring steel with tungsten carbide tips offering self-sharpening effect, making them exceptionally durable. Replacing a section is done in just a few minutes at an affordable cost. Through the impact cut, the stalks are also shattered to facilitate their decomposition and reduce tire damage.

Low maintenance


With the use of a top shaft drive through sealed cast iron gearboxes running at low speed, the maintenance is minimized. Four (4) grease points and chain lubrication are the only daily maintenance required. Only 2 chains drive the gathering drums which also serve as gathering chains to transport the stalks continuously up to the harvester feedrolls. The Dion exclusive O-ring chain design is resistant to dust and silage juice. Overloads and starting loads are absorbed by a friction clutch to operate smoothly and eliminate the need for shearbolts.

Higher Silage Quality


By maintaining the crop in the gathering chains, with continuous flow to the harvester feedrolls, without using a transverse auger, the stalks are fed base first and aligned perpendicular to the feedrolls. This provides a uniform length of cut without unwanted long particles that affect storage compaction and silage fermentation quality.

Boost your harvester performance!


A uniform flow, full width harvest unaffected by row alignment, increases your harvester performance.  It provides more throughput per hp, less driver fatigue and more acres per day, all increasing productivity and profitability.  With a (3m) 10ft width, a clean new track for the tractor is cleared at every field pass; useful for wet conditions and less damaging to the soil.


Dion rotary heads feature a universal frame and offer drive kits adapted to most pull-type harvesters on the market.  See the option tab for more details.
