Serviceability and road transport have never been easier with the 612C Corn Head. The Perma-Glide points and deck covers can be quickly and easily raised for access to each row unit. No tools are required.
The 600 Series Corn Head dual auger strippers significantly reduce the amount of auger wrapping in heavy grass, vines, or wet/damp down corn, as well as keeping ears down in the auger floor rather than riding over the top of auger.
Both auger strippers are strategically located, so the top stripper remains at the needed position relative to the auger flighting and does not require adjustment.
Once the auger has been set to the crop condition, the lower stripper can be adjusted 6 mm to 13 mm (1/4 in. to 1/2 in.) to the auger flighting.
Intermeshing knife stalk rolls consist of six full-length blades that contact the crop. The blades cut, crimp, and break the stalks as they are pulled down through the rolls. The full-length blades provide total crop contact for maximum chopping and cutting action from the front to back. Intermeshing knife stalk rolls are also available on StalkMaster™ corn heads.
The 600C Corn Head features chopping disconnect on all StalkMaster corn heads. Each row unit on the StalkMaster corn head has a shifting lever on the right side of the chopping gearcase to turn off the chopping functionality.
No additional tools are required to disconnect the feature. All rows can be disconnected with the shifting lever in less than 2 minutes. Chopping disconnect provides the flexibility to customize stalk processing from field to field.
The Perma-Glide points and deck covers can be quickly and easily raised for access to each row unit. No tools are required.
Simply raise the row-unit point, and the spring-loaded pull pin will automatically latch. To raise the deck cover, just pull the slam latch deck cover lever, and lift the entire point and cover straight up and out of the way. All inner points and deck covers incorporate a gas strut lift-assist cylinder that reduces the lifting force and maintains the point and deck covers in the upright position eliminating the holding rod.
Serviceability and road transport has never been easier with the 600C Corn Head.
In order to access the outside gathering chains and sprockets, simply raise the row-unit point (like the inside row-unit points), pull the spring-loaded pin located at the back of the unit, and tip the cover outward.
Replaceable wear strips on the inside of each point ensure the header will last and maintain its looks for years to come.
Perma-Glide points are easy to adjust and level. Simply pull out on the spring-loaded pin and adjust the height to one of four predetermined positions. No tools are required and no time-consuming height adjustment bolt or chain is used.
Perma-Glide is a tough, durable, solid polyethylene material:
The gathering sheet extensions are integrated into the outer gathering shields.
In order to extend the gathering sheet, simply raise the extension. The spring-loaded button will snap into place, securing the gathering sheet in the upright position for specific conditions where extended gathering shields are needed.
To lower the extension, push in on the spring-loaded button and lower the gathering sheet into the storage position.
The entrance into the auger bed floor of the 600 Series Corn Head has been lowered in comparison to previous John Deere corn heads. This enables gravity to do its job and let crop follow the slope designed into the auger bed and move it quickly away from the row unit.
Advantages of a lower auger bed floor include:
The large, 45.7-cm (18-in.) tip diameter cross auger provides unmatched crop-handling capacity. The cross auger flighting is reversed in the center, tilting back 20 degrees at the beginning and then an additional 20 degrees the last 5.08 cm (2 in.) toward the tip.
The reverse flighting offers improved feeding in dry trash and reduced ear tossing and will prevent the wrapping of crop. The 66-cm (26-in.) pitch on the cross auger provides quick delivery of crop to the feederhouse, allowing for faster and much-smoother crop feeding.
The 600 Series cross auger runs at a speed of 135 rpm with the combine backshaft speed set at 700 rpm. The slower auger speed reduces ear tossing in front of the feederhouse and keeps material moving from the back of the row unit into the auger. Keeping the material flowing helps dry trash and down corn feeding.
Adjustment of the cross auger can be done by loosening the bolts at each end of the head and moving the auger up or down.
Opposed knife stalk rolls are proper equipment when harvesting dry corn with the StalkMaster™ stalk chopping option.
To cut and size cornstalks (25.4 cm [10 in.] to 40.6 cm [16 in.] in length) during harvest, knife stalk rolls are recommended.
Benefits of opposed knife stalk rolls include:
The massive gathering chains are based on a CA620 chain design. After the initial stretch of this chain, the operator can expect increased chain life and once a season adjustment.
Attached to the gathering chain are conveying lugs. The gathering chain is exposed at the front of the row unit to enable better gather of down corn, while the attachment link profile reduces trash intake and shelling loss.
The idler sprockets were redesigned to distribute chain load and increase chain life. The new idler bearing contains a triple lip seal plus an additional sealed outer steel shroud for greatly increased bearing protection.
The chain guides have been redesigned with a raised roller surface to ensure gathering chains roll on the profile of the guide. Running on the rollers of the chain increases overall system efficiency by reducing friction, which results in increased gathering chain life.
Harvesting corn with RowSense
AutoTrac RowSense is a solution for corn growers that increases machine efficiency and reduces operator fatigue. AutoTrac RowSense offers operators the same high levels of convenience and productivity experienced in other crops or with AutoTrac-equipped tractors and self-propelled sprayers.
The AutoTrac RowSense increases machine efficiency by:
AutoTrac RowSense reduces operator fatigue by:
NOTE: AutoTrac RowSense requires a StarFire™ 3000 or StarFire iTC position receiver, GreenStar™ display, AutoTrac SF1, SF2, or RTK software activation, RowSense software activation, RowSense attachment (for 90 and 600 Series Corn Heads) includes the mechanical sensors, and will operate on S-Series Combines with integrated AutoTrac.
A combine retrofit kit (available through John Deere AMS) may be needed to make combines compatible with AutoTrac RowSense. This attachment includes a wiring harness to make the current AutoTrac system compatible with AutoTrac RowSense.
Due to their increased accuracy, a SF2 or RTK signal is the preferred choice for harvesting applications. For information on StarFire signals and recommendations, see the AMS product information on StarFire iTC Receivers.
NOTE: See the Ag Management Solutions AutoTrac story for the S-Series Combines for additional information.
For specific information regarding RowSense field-installed attachments or kit availability, as well as specific model year STS™ Combine and corn head (90 and 600 Series) compatibility, it is highly recommended to view the John Deere AMS product information.
