The heavy-duty epicyclic knife drive
The HydraFlex system hydraulically controls the float of the cutterbar by the 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 merely adjusts to a desired cutterbar ground pressure, and the system maintains this setting. If a different set point is desired, the operator simply adjusts the encoder on the armrest board, and an updated cutterbar float pressure reading is displayed on the cornerpost display. To make the cutterbar heavy to the ground for increased ground following in uneven terrain simply decrease the cutterbar pressure. If soil pushing occurs, simply make the cutterbar pressure to the ground lighter by increasing the cutterbar pressure.
