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.
NOTE: The hydraulic cylinders will be on every other channel on 630F and 635F models in model year 2022.
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.
The heavy-duty epicyclic knife drive gearbox provides an enhanced knife-drive system that increases drive capacity with less vibration and improved reliability.
