John Deere 770
SPFH Corn Header Series
The 770 Rotary Harvesting Unit features four large drum units and one small drum located on the outside of the left-hand and right-hand sides of the machine. Small drums were put on the outside of the harvesting unit to better handle low-tonnage requirements. Big drums handle high tonnages of crop better than small drums.
- Large drum cutting enables cutting of fields
- Harvesting down or lodged crops
- Advanced header-height control
- Row scrapers and cleaners prevent crop buildup
