The entrance into the auger bed floor of the 608C Corn Head has been lowered in comparison to previous John Deere corn heads. This enables gravity to do its job and let crop follow the slope designed into the auger bed and move it quickly away from the row unit.
The opposed knife stalk rolls are the best equipment when the typical harvesting condition is dry corn and using the StalkMaster™ stalk chopping option.
Customer Value:
- Majority of stalk material will be sized at 12 inches or longer to provide soil protection from wind and water.
- Designed to harvest with low power consumption for high performance and low fuel consumption.
Manufactured of highly durable material for longer wear life.
Theory of Operation:
Opposed knife stalk roll
Rolls are designed with eight opposed, full-length blades that result in better stalk control, improved stalk processing, and reduced material-other-than-grain (MOG) intake. This eight-blade design improves function and reduces localized blade wear in the front of the rolls. Rolls are constructed of austempered ductile iron material with a dual coating in the front 7.6 cm (3 in.) of high-wear zone for longer life.
The stalk rolls turn at 1050 rpm when back shaft speed is at 700 rpm. The tip speed compared to the gathering chain speed is optimized to reduce MOG intake and increase overall capacity while minimizing losses.
The single-piece cast knife roll design provides excellent serviceability when replacement is required.
