Features

Epicyclic knife drive increases drive capacity

The heavy-duty epicyclic knife drive gearbox provides an enhanced knife-drive system that increases drive capacity with less vibration and improved reliability.

Feature benefit:
  • Provides high level of reliability and durability
  • Minimizes vibration
  • Fast, efficient cutting action for higher harvesting speeds
Epicyclic knife-drive gearboxEpicyclic knife-drive gearbox
Functionality:
  • 89-mm (3.5-in.) knife stroke adds a more efficient cutting action. The increased stroke improves the cutterbar's ability to cut even in adverse conditions, such as large-stemmed crops or weeds, without plugging.
  • Knife speed is 520 rpm.
  • Reliability is improved with in-line versus wobble-geometry knife head, which oscillates in a straight line and not through a radius like the previous knife drive.
  • Knife head and gearbox attachment are improved. Two cap screws can be easily removed if any service to the knife is required.
Enhanced single-point latching system is fast and easy

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.

 

Feature benefit:

  • Reduces the time required to change over headers, so there is more time available for harvesting.
  • No tools required to remove headers for transport or storage.

 

Functionality:

 

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.

HydraFlex™ float system improves operator control

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.

 

Feature benefit:

  • Float arms, with hydraulic cylinders at every other channel, have replaced the mechanical linkage. These cylinders provide the cutterbar with the ability to float over uneven ground conditions with improved operator control.
  • The platform HydraFlex system with an accumulator maintains a constant ground pressure over changing ground conditions. Manual mode is for locking out the cutterbar in the rigid mode.

Hydraulic cylinders at every channelHydraulic cylinders at every channel
Functionality

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 reel relief valve protects the reel from damage when cutting short, heavy, wet crops that are down and tangled.

 

The valve allows the reel hydraulic motor to go into relief-pressure mode to stall the reel and reduce potential damage.

Auger Flight and Rear Stripper Extensions - BH84329

Auger flight extensions along with the rear auger stripper help bring crop to the center of the feederhouse opening for improved feeding performance.

Platform wedge kit - BH84398
Wedge kitWedge kit

In certain field conditions, when harvesting with 600 Series cutting platforms attached to pre-60 Series combines equipped with tall drive tires (for example, 35.5x32-in. or 42-in. dual wheels), it may not be possible to obtain the desired or optimum cutting bar angle. This is due to the extreme height of the drive tires, especially if used in conjunction with the tall 18.4x30 or 28Lx26 high-flotation rear steering tires.

 

The wedge kit allows the lower frame of the platform to be tilted upward to any one of three different degrees when attached to the combine so the desired cutter bar angle adjustment can be obtained.

Distance between center of F.H. and the groundDistance between center of F.H. and the ground

The following chart and illustration below can be used to help determine if the wedge kit is required on the platform for the combine being used.

 

Position machine on flat level ground with platform removed.

 

Position feederhouse so face is perpendicular to the ground. To check this, a bubble level can be placed on the face of the feederhouse.

 

Measure distance (A) between the center of feederhouse drive shaft and the ground.

 

Compare dimension to table and determine amount of wedge angle required.

Raised Cut Height Skid Shoes, Flex Platforms 22 Ft., 25 Ft. - BH84326

The raised cut-height skid shoes option helps to provide added protection in field conditions where excessive rocks and other field debris are present or tall, damp, high residue from double-crop operations exists within the standard low-height cutting range of the 600 Series Flex Platforms. The raised-cut-height design of this skid shoe increases the cutterbar cutting height from 38 mm (1.5 in.) to 63 mm (2.5 in.).

 

Feature benefit:

  • Provides added protection in field conditions where excessive rocks and other field debris are present
  • Allows for an increased cut height when harvesting in high residue from double-crop operations
  • Raised cut-height skid shoes ordered as a dealer- or factory-installed option are available on all 600F Platforms.

Optional 63-mm (2.5-in.) skid shoeOptional 63-mm (2.5-in.) skid shoe
Functionality

The raised cut-height skid shoes raise the cutterbar. This keeps the knife farther from the ground where excessive rocks and other field debris are present. The raised cut-height skid shoes also raise the cutterbar to keep the knife clean when harvesting in high residue from double-crop operations.

Reel Position (Fore/Aft and Height) Resume for use on all 600 Series Platforms - BH84265

Three programmable reel position settings will optimize platform performance while minimizing header losses.  The operator can preselect three different reel positions for specific field conditions and can access these while harvesting, simply by touching the activation buttons on the multifunction hydro handle.

 

Feature benefit:

  • Three programmable positions to optimize platform performance
  • Reduces operator stress by conveniently moving the reel to a preselected position to minimize header losses

Functionality:

 

Adjust the reel height and fore-aft position to an optimal position then press the 1, 2, or 3 button on the multifunction control lever until arrows on each side of the symbol indicates that the system is active. This will save that reel position for that button which can be done for each number on the handle.

Stone Dams Short (23 mm) for 622F and 625F - BH84404

The stainless-steel feed plates on the 600F Series Platforms have a flat profile. This along with the stainless-steel material, results in smoother feeding into the platform auger. The 600F offers an optional tall stone dam at the cutterbar to help prevent rocks from entering the platform.

 

Feature benefit:

  • The stainless-steel feed plates have a flat profile that provides smoother feeding into the platform auger.
  • The feed plates pivot from the rear. During normal operation, the profile of the feed floor is flat, which improves feeding geometry and also maintains a consistent clearance between the reel and cutterbar, allowing improved crop flow from the cutterbar to the auger.
  • Short stone dam is in base equipment and recommended for use in tall, short, and no-till crop conditions. The short wall of this stone dam provides smooth feeding without affecting crop flow into the platform
  • Tall 50-mm (2-in.) stone dam is available as a factory-installed option and is recommended where extremely rocky field conditions exist. The taller wall of this stone dam acts as a barrier to prevent rocks from entering the platform and the possibility of ingestion into the combine.

The flat feed plates also allow a consistent clearance between the reel and cutterbar improving crop flow from the cutterbar to the auger.
