Row sensing is done by the use of feelers
The AutoTrac RowSense increases machine efficiency by:
-
Maintaining efficiency through changing crop conditions
-
Reduce grain loss
-
Improve acre-per-hour combine performance
AutoTrac RowSense reduces operator fatigue by:
-
Enhanced comfort during long harvest hours
-
Easier operation in reduced-visibility (dusty) conditions
-
Reduced operator stress in down corn situations
StarFire position receiver picks up signal
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.
Intermeshing stalk roll options for premium stalk processing
600C Row-Unit
The intermeshing knife stalk rolls are the best equipment when the typical harvesting condition is wet corn and using the StalkMaster™ stalk chopping option.
Customer Value:
- Majority of stalk material will be sized at 15.2 cm (6 in.) or longer to provide soil protection from wind and water.
- Designed to harvest with low power consumption for high performance and low fuel consumption.
Manufactured of highly durable material for longer wear life.
Theory of Operation:
Intermeshing stalk rolls
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. Rolls are constructed of austempered ductile iron material with a dual coating in the front 7.6 cm (3 in.) of high-wear zone for longer life.
The stalk rolls turn at 735 rpm when back shaft speed is at 490 rpm. The tip speed compared to the gathering chain speed is optimized to reduce MOG intake and increase overall capacity while minimizing losses.
The single-piece cast-knife roll design provides excellent serviceability when replacement is required.
Folding capability speeds transport between fields
608FC Folding Corn Head
Each of the outer two rows of the 608FC fold hydraulically from the cab to allow for narrow transport width during road transport between fields or for storage.
Customer Value:
- Eliminates the need for header transport trailer, reducing the cost of total harvesting equipment.
- Reduces nonproductive harvesting time used to mount header to a transport trailer and reattach it to the combine at the next field.
Theory of Operation:
Folding cylinders on 612FC shown
Two large, durable-frame folding cylinders provide smooth hydraulic force to move the corn head wings from the working position or field position to the transport position.
Armrest display
The control of the 608FC folding function is integrated into the operator cab of S-Series Combines. Operators can fold the 608FC quickly and easily from the armrest display screen without leaving the cab.
Opposed stalk roll options for premium stalk processing
600C Row Unit
The opposed knife stalk rolls are the best equipment when the typical harvesting condition is dry corn and using the StalkMaster™ stalk chopping option.
Customer Value:
- Majority of stalk material will be sized at 12 inches or longer to provide soil protection from wind and water.
- Designed to harvest with low power consumption for high performance and low fuel consumption.
Manufactured of highly durable material for longer wear life.
Theory of Operation:
Opposed knife stalk roll
Rolls are designed with eight opposed, full-length blades that result in better stalk control, improved stalk processing, and reduced material-other-than-grain (MOG) intake. This eight-blade design improves function and reduces localized blade wear in the front of the rolls. Rolls are constructed of austempered ductile iron material with a dual coating in the front 7.6 cm (3 in.) of high-wear zone for longer life.
The stalk rolls turn at 1050 rpm when back shaft speed is at 700 rpm. The tip speed compared to the gathering chain speed is optimized to reduce MOG intake and increase overall capacity while minimizing losses.
The single-piece cast knife roll design provides excellent serviceability when replacement is required.
StalkMaster™ row-unit enables stalk chopping
StalkMaster row-unit
The StalkMaster Corn Head chopping system allows operator size and chop corn stalks while harvesting, eliminating second-pass operations and saving time. StalkMaster is available on 606C, 608C, 612C, 612FC, 616C, and the 618C Corn Heads.
Customer Value:
- Uniform sizing of corn stalks to speed decomposition and also providing for soil protection from wind and water.
- Eliminates the need for the second-pass operation to size stalk residue, saving time and expense.
- Can be equipped with either intermeshing or apposed knife stalk rolls to match the agronomic needs of individual growers.
- Features a quick, no tools, disconnect feature that provides producers the flexibility to chop, or not, when desired.
Theory of Operation:
StalkMaster chopping blades
Each of the StalkMaster row-unit gearcase is equipped with two heat-treated and wear-coated rotating blades positioned below the stalk rolls. As stalks are pulled through the rolls stalks are cut to size and distributed evenly throughout the row. If the blades encounter an obstruction they will swing backward avoiding damage and interruption to harvest. Blades can be reversed to extend their useable wear life.
StalkMaster chopping disconnect feature
The gearcase on the StalkMaster row-units feature a no tools needed disconnect. Each row has a convenient shifting lever on the right side of the gearcase to turn the function on or off in a matter of minutes.
StalkMaster gearcase
A heavy-duty slip-clutch design protects both the row-unit gearcase and the StalkMaster lower chopping unit gearcase. If the clutch slips, the operator will know immediately.
Rubberized curtains
Steel-protective shield
StalkMaster chopping heads feature side- and rear-mounted rubberized curtains to optimize chopped crop residue distribution. Also, the right-hand side of the head has an additional shield for protection from protruding blades.
612C right-hand side and drive shaft
Enclosed chain cases drive the gathering chains and stalk rolls for each row to provide robust durability and uninterrupted harvesting. Heavy-duty bearings mounted in machined castings along with O-ring seals increase life and improve serviceability.
Larger sprockets and chain
Continuous-loop American National Standards Institute (ANSI) #100 chain allows for higher loads and longer life by eliminating all connector links and half links. The large-diameter sprockets along with large 38-mm (1.50-in.) transverse hex back shaft and row-unit shafts provide for improved sprocket and chain life.
Telescoping drive shaft
Telescoping drive shafts mount to the splined feederhouse back shafts on all 50, 60, 70, W-, T-, C-, and S-Series Combines.
The coupler features an 8-degree index, allowing the operator to match the drive shaft splines without rotating the platform feederhouse.
Telescoping drive shafts:
- Feature fast, no-tools coupler
- Can be retrofitted to earlier 90 Series and 40 Series Corn Heads
Hydraulically adjustable deck plates
Hydraulic deck plates
Hydraulically adjustable deck plates allow the operator to adjust the deck plate opening on the go in order to match changes in stalk or cob size and crop conditions.
Customer Value:
- Minimize material-other-than-grain (MOG) intake providing improved separator performance.
- Reduce ear loss to maximize potential yield.
- Minimize premature shelling and kennel damage proving sample quality.
Theory of Operation:
Hydraulic deck plate feature is controlled by the operator with the multifunction control handle on the go from the cab.
Deck plate spacing
The deck plate spacing indicator is displayed on the corner post display and on the CammandTouch™ display unit on the armrest.
Deck plate resume is also featured with hydraulically adjustable deck plates. Three deck plate positions can be programmed for varying crop conditions using the resume feature.
