Features

 

The massive gathering chains are based on a CA620 chain design with deep conveying lugs for high levels of productivity.

 

Customer Value:

• Large, deep conveying lugs provide high levels of productivity for faster harvesting.
• Robust design and construction ensure maximum uptime and minimum maintenance.

Theory of Operation:

 

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 adjustment once a season.

 

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 designed to distribute chain load and increase chain life. The idler bearing contains a triple-lip seal plus an additional sealed outer steel shroud for greatly increased bearing protection.

 

The chain guides have been designed 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.

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. 

 

The 600C Corn Heads feature a large, 45.7-cm (18-in.) tip diameter cross auger provides unmatched crop-handling capacity. 

 

Customer Value:

• The deep auger flight design provides for even crop material flow, allowing faster harvesting speeds.

Auger to row-unit speed is optimized to feeding of crop and minimizing crop loss due to ear tossing.

Theory of Operation:

 

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.

 

The drive system on non StalkMaster 600C Corn Heads is designed with robust components to match the high capacity that these heads provide.

 

Customer Value:

• High levels of reliability and durability to ensure maximum uptime.
• Designed to efficiently transmit power for high performance and low fuel consumption.
• Minimum routine maintenance minimizes lost time and expense.

Theory of Operation:

 

The non StalkMaster main drives feature:

• Enclosed gearcase drives the gathering chains and stalk rolls for each row
• Heavy-duty bearings in machined castings along with O-ring seals increase life and improve service
• Continuous loop American National Standards Institute (ANSI) #80 chain allows for higher loads and longer life as all connector links and half links are eliminated

Large-diameter sprockets for improved sprocket and chain life

 

• Large, 31.75-mm (1.25-in.) transverse hex backshaft and row-unit shafts, which have their own positive slip clutch protection 
• Auger drive chains are ANSI #80 chain for longer life and durability
• Easy access to adjust the auger drive chain once a season 
• Row-unit gearcase oil is added from the top
• Once-a-season service of greasing telescoping back shafts, main-drive lube check, and row-unit gearcase grease check

 

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

 

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:

 

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.
