712FC Folding Corn Head
- Available in 12-row models in 76.2-cm (30-in row spacing)
- StalkMaster™ and non-StalkMaster options
- 712FC cycle fold time is less than one minute in either direction, up or down
- Folding function controlled by the armrest display screen or hydro handle switch
Folding corn heads perform exceptionally well at higher harvesting speeds while providing narrow transport widths when attached to the combine, which means operators can finish faster.
- The 700FC reduces cost of operation by eliminating the need to purchase a header trailer to transport corn heads between fields during harvest.
- Eliminates the time needed to mount the header to a trailer and reattach it to the combine at the next field.
- Reduces the space needed to store the corn head.
Theory of operation:
Two large folding cylinders provide smooth hydraulic force to move the corn head wings from working position to transport position.
Folding functionality is integrated into the cab, allowing customers to quickly fold the corn head from the 4600 CommandCenter™ Display without leaving the cab.
Customers have asked for stalk rolls to appropriately size residue for their operation while managing power and overall header weight.
John Deere offers RowMax stalk rolls to address customer needs around residue, power, and weight for their front-end equipment.
RowMax stalk roll features and benefits:
- RowMax stalk rolls can improve wear life by 25 to 30 percent compared to the 600C base stalk rolls.
- Three stalk roll options allow customers to select the appropriate length of corn stalk residue.
- To provide high performance during harvest, RowMax stalk rolls are designed with reduced power and fuel consumption in mind.
- RowMax Chopping Stalk Roll drops stalk residue on top of the row for improved planting performance for no-till and strip-till customers the following season. Additionally, the chopping stalk roll blossoms the top of the stalk for reduced tire and track damage.
RowMax stalk roll details:
- The stalk rolls are manufactured from highly durable austempered ductile iron material with an added wear coating for increased wear life.
- The full-length blades provide total crop contact for appropriate sizing and cutting action from front to back.
- Stalk roll tip speed compared to gathering chain speed is optimized to reduce material-other-than-grain (MOG) intake and increase overall capacity while minimizing losses.
- Enclosed chain drives gathering chains and stalk rolls for each row to provide robust durability and uninterrupted harvesting.
- Single-piece cast knife roll design provides excellent serviceability when replacement is required.

The 700C/FC Corn Head RowMax row-unit provides customers increased durability and longer wear life. RowMax row-units include updates to gathering chains, gathering chain sprockets, chain guides, and stalk rolls. These improvements extend the life of the corn head for lower ownership cost.
- Increased wear life of row-unit gathering chains and sprockets by 50 percent due to solid alloy pin bushings and increased number of sprocket teeth
- Increased wear life of stalk rolls up to 30 percent with an improved wear coating
- Maintain corn head performance durability with an increase in stalk roll material hardness
To extend the life of the corn head, the RowMax row-unit increases the number of sprocket teeth on gathering chains from six teeth to eight teeth. The gathering chain has an additional 12 links and an anti-bend back feature on the chain lug. Gathering chain wear is reduced by using a solid alloy bushing.
Available as an option, StalkMaster provides ultimate stalk sizing by processing stalks smaller than stalk rolls allowing the operator to potentially eliminate second-pass operations, saving time, fuel, labor, and additional operating costs.
- Consistent sizing of corn stalks to speed up decomposition and provide soil protection from blowing wind and water runoff
- StalkMaster can be equipped with either intermeshing, opposed, or chopping stalk rolls
- Ultimate flexibility to chop or not chop when desired through a quick, no-tools-required disconnect feature
Each StalkMaster row-unit gearcase is equipped with two heat-treated and wear-coated rotating blades positioned below the stalk rolls. The blades can be reversed to extend their wear life. These blades cut stalk to size and distribute residue evenly throughout the row. If the blades encounter an obstruction they will swing backward, avoiding damage and interruption to harvest.
The StalkMaster row-unit gearcase feature a no-tools-required disconnect. Each row has a lever on the right side of the gearcase to turn the function on or off in a matter of minutes if desired, allowing for lower fuel consumption.
A heavy-duty slip-clutch design protects the row-unit gearcase and the StalkMaster lower unit gearcase.
The gathering chains and stalk rolls for each row are enclosed to provide robust durability. Heavy-duty bearings along with O-ring seals improve serviceability.
A continuous-loop chain allows higher loads and longer life by eliminating all connector links and half links. The large-diameter sprockets along with a large 38-mm (1.50-in.) transverse hex back shaft and row-unit shaft provide improved sprocket and chain.
A telescoping drive shaft mounts to the splined feederhouse back shaft on all 50, 60, 70, W-, T-, C-, and S-Series Combines.
The coupler features an 8-degree index, allowing the customer to match the drive shaft splines without rotating the platform feederhouse.
Telescoping drive shafts can be retrofitted to earlier 90 Series and 40 Series Corn Heads.
StalkMaster row units feature side- and rear-mounted rubberized curtains to optimize residue distribution. The right-hand side of the head has an additional shield to protect customers from protruding blades.
Post-emergence operations such as harvesting corn in October can be stressful for operators. AutoTrac RowSense, an innovative global positioning system (GPS) steering system, reduces overlap and fatigue during harvest. On top of steering the machine, an operator is required to monitor several other areas such as the header feeding, ground terrain, combine settings, or managing tender trucks and grain carts. Operating at night, in windy conditions, or while harvesting lodged corn can add even more stress for the operator.
- Continue harvesting in down crop and dusty conditions
- Increases acre-per-hour potential and reduce grain loss
- Enhances operator comfort while reducing stress
