The 600FD Series HydraFlex Draper Platform features HydraFlex, an industry-exclusive hydraulic float system allowing for superior ground following capabilities over a wide range of crops and conditions.

Feature benefit:

• The HydraFlex system hydraulically controls the float of the cutterbar by the turn of a knob in the cab for ease of operation
• Provides exceptional cutterbar flexibility throughout the entire working pressure range for increased machine performance
• Unique cutterbar float arms offer a dual purpose, allowing for superior ground-following capabilities plus support to the cutterbar and draper belts for increased productivity

Functionality

From the cab, the operator can simply adjust the armrest encoder knob which varies the hydraulic pressure in the float arm hydraulic cylinders. This controls the cutterbar ground pressure depending upon conditions.

With the HydraFlex float system, the operator varies the cutterbar ground pressure but does not affect the cutting height of the crop, even at high ground speeds. The hydraulic float system features a 19-cm (7.5-in.) float range, allowing for optimum float pressure. To lock out the HydraFlex draper into rigid mode, the operator increases the float pressure to maximum.

Dual knife drive

Dual knife drive is standard on 600FD HydraFlex™ Draper Platforms for harvesting rice, tough crop, and in wet or green crop conditions. This unique dual knife drive system is timed, creating the smoothest possible reciprocating knife drive system currently in the industry.

Positive, reliable, power take-off (PTO) shaft and driven, dual epicyclical in-line knife drives with built-in driveline protection provides producers with the strongest knife drive system in the industry.

NOTE: The single knife drive is available on the 630FD, but increased cutterbar vibration may occur.

40.6-cm (16-in.) feed drum

The 40.6-cm (16-in.) feed drum improves the crop handoff from the draper belts, resulting in increased material handling and productivity of the 600FD HydraFlex™ Draper Platforms.

Feed drum retractable auger finger

A feature for 600FD Draper Platforms is a feed drum retractable auger finger to improve crop feeding at the corners of the feed drum. In some crop conditions, the crop can hesitate at the corners of the feed drum, and the retractable drum fingers keep the crop moving into the combine. This results in smoother feeding and better performance of the combine.

The speed of the side draper belts can be controlled by an adjustment on the CommandARM™ controls from within the cab. Combine software gives operators the option to slow down the side belts to a fixed speed with a push of a button on the CommandARM. Additionally, a draper belt protection system is integrated into the 600FD HydraFlex™ Draper Platform family to minimize side belt damage should slippage occur.

Feature benefit:

• Optimal performance in varying crops and conditions through side draper belt speed that ranges from 22.6 m to 228 m (74 ft to 748 ft) per minute and shows on the display in the cab
• The center draper belt speed is fixed at 211 m (692 ft) per minute for optimal feeding to the combine feederhouse
• Speed sensors monitor the speed of the idler rollers and should major slippage be experienced, the belts will shut off and an operator warning is shown on the CommandCenter™ display
• Side belt speed reduction is designed to improve draper performance when the operator is not harvesting the full platform width or when coming out of a headland
• Increased uptime as the side belt speed reduction feature is engaged/disengaged from the CommandARM controls
