Auger flight design

6X9 Series Pickup auger

The 6X9 Series Pickup features an updated auger design. The flights on the auger move the crop inwards to the center of the machine. The movement of the flights creates an endless flow for smoother feeding around the corner towards the feedrolls of the SPFH.

• The crop is carried to the middle of the pickup by the auger, and due to endless flighting, there is a smooth transition into the feedrolls which helps crop flow and quality of cut.
• Crop is more evenly distributed over the full channel width.

The advantage of the John Deere self-propelled forage harvesters (SPFH) is that the speed of the pickup changes if the length of cut (LOC) is changed. This has enormous benefits for the producer.

For example, if the LOC is set longer, the header is also driven faster, which means the crop is fed faster towards the SPFH. This increase results in a more even crop flow and better feeding of the SPFH.

The speed of the pickup is constantly monitored with a speed sensor in the driveline. There are drive options to allow the individual speed of the pickup reel and auger to better adapt to varying field conditions.

• The variable drive coming from the SPFH guarantees the basic pickup speed is always in line with the feedroll speed according to the LOC setting of the SPFH.

Roller compressor with alfalfa plate attached

Accumulator releasing part of the weight

The standard compression unit with a self-adjusting roller adapts automatically to the size of the swath. Especially in light swaths, the SPFH can only be loaded evenly if the compression unit is in the right position. The roller rolls smoothly over the swath as the accumulator releases part of the weight of the roll.

• The roller compression unit with the rake automatically adapts to the swath size, which results in an optimum crop flow. This is especially important when harvesting various swath sizes.
• The alfalfa plate is recommended in large windrows for more even feeding.

Gauge wheels folded out in working position turn 360 degrees

The gauge wheels can turn 360 degrees; therefore, they are very easy on the soil. The large tyre diameter performs well on wet ground.

The wheels perfectly follow the ground contours and do not work the soil; they can turn unlimited in field corners.

During transport, optional hydraulic cylinders can be used to fold the wheels within the pickup width. 

Header hookup point

Header attached to the self-propelled forage harvester

The header is easy to hook up to the self-propelled forage harvester (SPFH). The hookup point automatically slides into the center and is clearly visible from the cab. It locks mechanically with one handle.

Multicoupler connection on the SPFH

Multicoupler connection on the pickup

A multicoupler is available for all electric and hydraulic connections. It makes for quicker and easier attachment to the SPFH. Automatic header recognition engages when the header is connected to the SPFH. This allows the operator to utilize the easy and automatic settings of the header/SPFH combination - all settings are stored in the machine. The optimal auger speed engages based on the length of cut (LOC).

• Automatic header recognition allows the operator to quickly and efficiently attach and detach the header. More time is saved, and there is increased comfort when going from grass to corn to allow for more time in the field.

Pickup unit

The trash net covers the auger and attaches to the arms of the compression unit. The fine mesh prevents crop buildup all over the machine, including the cutterhead cover. It does a good job of keeping the most valuable part of the plant—the leaves—in the feed.

• The net prevents debris from accumulating on the cutterhead, which results in less cleaning of the self-propelled forage harvester (SPFH) and the pickup.
• Leaves and delicate forage remain in the pickup.

Heavy-duty premium pickup reel

Standard pickup reel

For extremely tough harvesting conditions, John Deere offers the premium pickup reel option for the 639 Windrow Pickup. The premium parts are standard equipment on the 649 and 659 Windrow Pickups.

The premium pickup includes a range of heavy-duty driveline and pickup reel parts. The main wear parts are also Dura Line™ coated.

Pickup tines and pickup tine support

6-mm (0.24-in.) premium and 4.9-mm (0.19-in.) standard pickup tines

The 6-mm (0.24-in.) thick premium tines will be able to feed the heaviest swaths toward the auger. The larger spring coils of the thick tines are more flexible, resulting in an improved lifetime. The thick tine is capable of handling the extra force placed on them when harvesting very heavy crops with a large SPFH.

Premium pickup tine support

The pickup tine support on the premium pickup increases the contact surface between the tine and fixation, resulting in longer service life of the tine as the forces are better distributed from the tine into the toothbar.

Toothbar and pitman

Premium U-shaped tooth bar and standard angled bar

Premium pitman and standard pitman

To handle the extra power, the tooth bars are U-shaped. The U-shape gives extra stability so it can cope with the extra forces placed on it by the thicker tines. The pitmen holding the toothbars were made more stable.

Cam track and bearings

Premium cam track and standard cam track

Premium bearing and standard bearing

The size of the bearing holding each pitman increased from 40 mm to 52 mm (1.6 in. to 2 in.), an increase of 12 mm (0.47 in.).

Spider

Premium spider and standard spider

A more robust spider keeps the bearings of the four pitmen in place.

Hexagon shaft

Premium hexagon 32-mm (1.3-in.) shaft and standard hexagon 28-mm (1.1-in.) shaft

The diameter of the hexagon shaft increased by 4 mm (0.16 in.) from 28 mm to 32 mm (1.1 in. to 1.3 in.).

Dura Line auger flight reinforcement strips

Dura Line long wear strips prevent wear on the outside of the auger flights.

Welding seam on the pickup auger

For better durability, there is a welding seam in the middle of the pickup auger on the special formed flight.

Dura Line deck plates, auger strippers, and deflector plates

In order to handle the intense wear and enormous crop flow in the central part of the machine, the deck plates, auger strippers, and deflector plates in this area are Dura Line coated to provide better wear characteristics and an increase in uptime.

639 standard pickup reel without center bearing

The pickup reel of the 649 and 659 Windrow Pickups is already supported in the middle by ball bearings. With the premium option, the 639 Windrow Pickup (3 m [9.8 ft]) is also supported with extra ball bearing in the middle. This extra support fits in the pickup reel using the same strippers as on the standard machine.

The premium heavy-duty pickup reel option is best suited for:

• Producers with a very high annual usage of the pickup

• Producers working under difficult conditions like:
  • Big swaths
  • High yields
  • Wet crops
  • Uneven fields

• Producers always striving for maximum productivity
• Producers who are looking for premium features for higher uptime and better performance

NOTE: The premium, heavy-duty pickup reel is only optional on the 639 Windrow Pickup for standard-body 8000 Series SPFH. It is standard on the 649 and 659 Windrow Pickups.

The standard pickup is best suited for:

• Producers or small contractors, with medium or low annual usage of the pickup (e.g. main crop is corn)
• Producers using the pickup under normal conditions
  • Average or low yields
  • Mainly dried crops
  • Even fields
• Producers who are looking for a low-cost solution
• Producers with medium horsepower SPFH
