The heavy-duty epicyclic knife drive gearbox provides an enhanced knife-drive system that increases drive capacity with less vibration and improved reliability.
John Deere’s single-point header latching system provides combine operators a fast and easy method for connecting all front-end equipment. One easy motion of the lever connects the electrical and hydraulic circuits along with header retaining pins.
The enhanced single-point latching system, starting in model year 2016, will include a valve assembly mounted to all platform and corn head back sheets. These assemblies will include an orifice valve unique to the header type as well as a pressure override valve. Together, these ensure optimum performance and reliability of header hydraulic functions.
Compatibility for prior headers or combines to model year 2016 equipment is provided by attachments specific to the header and combine being used.
The HydraFlex system hydraulically controls the float of the cutterbar by a simple turn of a knob in the cab. This provides exceptional cutterbar flexibility throughout the entire working pressure range. Higher ground speeds can be accomplished with HydraFlex, compared to the conventional float systems.
In automatic mode, the operator sets a desired cutterbar ground pressure, and the system will maintain this setting. If a different set point is desired, the operator adjusts the encoder on the armrest board, and an updated cutterbar float pressure reading will be shown on the cornerpost display. For increased ground following in uneven terrain, decrease cutterbar pressure to make the cutterbar heavy to the ground. If soil pushing occurs, increase the cutterbar pressure to make the cutterbar lighter to the ground.
