  • Takes only one person a few minutes to convert draper from field to transport without use of tools

    The 630D, 635D, and the 640D Draper models can be equipped with an integral, slow-speed transport system.


    Customer Value:

    • Dual-front dolly wheel tires with an extendable tongue and two-gauge wheel tires carry the complete weight of the draper when in transport, eliminating the need for a header trailer
    • One person can convert the draper from field to transport mode in a few minutes without the use of tools, expediting road transport

    Step 4-install transport tongueStep 4-install transport tongue


    In field mode, the dual wheels become the left- and right-hand gauge wheels. For transport, the left-hand dual-dolly wheels support one side of the draper frame and the right-hand dual wheels are repositioned to support the right-hand end of the frame.


    The transport package includes warning lights, which can be plugged into a seven-way power source for road transport with a 32.2-km/h (20-mph) speed limit for farm equipment transport.


    NOTE: The 630D, 635D, and the 640D Drapers are equipped with two 20.5 x 8.0 12-ply equivalent gauge wheel tires as base equipment and four 20.5 x 8.0 12-ply equivalent gauge wheels with the low-speed transport option.

    The unique dual-knife-drive system is timed, creating the smoothest-possible reciprocating knife-drive system currently in the industry. The positive, reliable shaft-driven dual epicyclical in-line knife drives with built-in driveline protection provide operators with the strongest knife-drive system.

  • Double-cut knife system produces a cleaner cut

    All John Deere 600D Drapers include a double-cut knife which features a hydraulic tilt that is controlled from inside the cab. All 10.6-m (35-ft) and 12.1-m (40-ft) draper cutterbars also have knifeback reinforcement straps to strengthen the knifeback.


    Customer Value:

    • Longer stroke of knife section provides a faster, cleaner, and smoother cut which allows operators to harvest at faster ground speeds maximizing productivity
    • Reinforced knifeback strengthens cutterbar for tough harvesting conditions maximizing performance
    • Hardened sickle sections and unique boron treatment extends wear life
    • Hydraulic tilt optimizes the cutterbar angle for varying conditions, extending the harvest day and providing the lowest-possible cut height

    Theory of Operation:

    The 100-mm (4-in.) cutting action produces a cleaner cut versus the tearing effect of shorter-stroke cutting systems. Knife hold-downs are easily adjusted to help maintain harvesting performance.

    The cutterbar hydraulic tilt adjusts a full 8 degrees while maintaining excellent visibility to the cutterbar throughout the tilt range. For improved ease of use the optional advanced hydro handle can be configured to control the platform tilt.

  • Reel resume and reverse are features on the 600D Drapers

    Reel resume and reverse are features on the 600D Drapers. The combine operator can store two different reel positions with one setting for normal conditions and another for down, tangled, short, leaning crops. 


    Customer Value:

    • Added time savings and convenience with saved reel positions, lowering operator fatigue
    • Reel-reverse feature reverses the reel in conjunction with the center feed drum and belt to back out plugs and increase harvest efficiency
