Rotary corn head cutting corn

Unmatched simplicity

No other corn head matches the simplicty of the F64 rotary head. Its drivetrain contains few parts and requires very low power. Only two chains are used to convey the crop and drive the drums. It does not use any auger and unlike regular rotary head, it conveys the stalks directly to the feedrolls in the best orientation: No dead space, even feeding and always regular length of cut. The conveying chains are unique to Dion. They are assembled with O-rings and require little maintenance. The use of sealed bearings on the head minimizes maintenace.

A four row corn head but only 2 gathering chains! The heavy duty ANSI #80 chain with 0-rings is pratically maintenance free. The exclusive chain design transports the crop with unprecedented fluidity and efficiency.

Boost your harvester peformances!

The F64 corn head is compatible with pull-type harvesters from Dion, John Deere, CaseIH, NewHolland and Gehl. Its exclusive concept combines the advantages of rotary and conventionnal headers. The versatility of rotary drums allows you to harvest faster, with less fatigue and without having to worry about row spacing and direction. You harvest at full width and full capacity even in asymetrical fields or tight corners. Taking back the field rounds is easy with the aggressive drums. Everything that is cut is harvested.

Designed based on a thorough development program, the patented concept unites the performance of rotary headers and the economy of conventional header. No other pull-type or self-propelled harvester system offers you so much for your money.

Better silage quality

The use of conveying chains ensures an umatched feeding evenness. You can maintain a higher harvesting speed and exploit all the power available. The perfect alignement of the stalks provides a more precise length of cut for a higher silage quality.

The ideal cut

Each rotary blade is driven by V-belts and rotates in the opposite direction to the drums. This design eliminates vibration and reduces noise. The four knife sections per disck are made of durable heat-treated steel. If replacement is ever needed, these parts are affordable and only a few minutes are required. The impact cut shatters the standing stalks to accelerate decomposition and reduce tire damage.
