Competitive advantages of the 6000 Series Harvestec Cornheads.

1. Knife roll comparison
Harvestec
•Exclusive serrated knife edges between the straight
knife blades provide 8 pinch points on the stalk per
revolution of roll, resulting in less stalk slippage, less
trash intake and finer chopped residue relative to
most competitors using just 4 knives/pinch points
•Blades are reversible to extend service life
•The serrated knife edges also crimp the stalks every
3” which helps accelerates the microbial breakdown
process for a better seedbed next spring which leads
to higher yields on the following crop.
•This accelerated breakdown process also leads to
more nutrient availability for the crop leading to
higher yields.
Harvestec Knife Roll Comparison

2. 2
Knife roll comparison
Most of competitors use a conventional design
with only 4 knives
•No additional edges between the knife blades
means only 4 pinch points on the stalk per roll
revolution resulting in much more stalk slippage
and more trash intake
•No serrated edges present which doesn’t crimp
the stalk and causes a much longer breakdown
period for corn stalks.
•This longer breakdown period leads to residue
hairpinning on tillage equipment and more
importantly planter row units which leads to a less
effective plant stand next spring which decreases
yield. This also leaves less nitrogen available for the
crop which also decreases yield.

4. Competitive Comparison
This stalk in the top half (left hand) of the picture was from a field harvested with a 6308 ( non-
chopping 30” 8 row) which shows the crimping action of the serrated knive edges which
accelerates microbial breakdown.
The stalk in the bottom half (right hand) was harvested with a conventional OEM header with just
4 knives on the snapping roll

5. Competitive Comparison of Residue
The top stalk show below was run through a 6308 non chopping head and it shows how the
Harvestec snapping roll crimps the stalk every 3” with the serrated edge which will speed up the
microbial breakdown process. The bottom stalk was harvested with a competitive conventional
head which had just 4 knives on the snapping roll. You can see how the knives barely “knicked”
the stalk which will cause the stalk to take 2-3 times longer to breakdown. This will cause hair
pinning on tillage and planters negatively affecting the seedbed which will also cause yield loss.

6. Competitive Comparison
This picture shows residue after it was harvested with a 6308 non chopping head and it shows how
the Harvestec snapping roll will still size the stalks into 4” to 8” chunks with a crimp every 3” which
accelerates breakdown putting more nitrogen in the ground increasing yields.

8. Chopping unit comparison
Harvestec
•2800RPM chopper speed
•Optimal front mounted chopper is close to
the underside of the rolls providing the
shortest, most consistent residue size.
•Visualize using a handsaw to cut wood.
Would you saw near the sawhorse or further
away? We use the same concept with the
chopper position.
•Chopper positioning allows running the
snapping unit closer to the ground in down
corn conditions without having the chopper
touch the ground.
•This reduces power consumption
maximizing efficiency.
•The positioning ensures short stubble height.
•Chopper gearbox can be easily disengaged
Harvestec Chopping Advantages

9. 9
Chopping unit comparison
A lot of competitors use a mid mount position
in relation to the snapping roll
•Mid roll position of chopper knives results in
higher stubble height
•Excessive distance from the underside of the
snapping rolls causes inconsistent residue
sizing
•Low chopper mounting means the row unit
must run higher causing difficulty in down corn
•Chopper has longer knives which require more
horsepower

10. Chopping unit comparison
Chopping Unit Comparison
A lot of competitors will position their choppers at the
very rear in relation to the snapping roll
•Chopper unit is a rear mounted gearbox on the frame
well behind the row unit.
•The snapping rolls eject the stalk completely before the
chopper blades make first contact, leaving inconsistent
residue sizing and higher stubble height and than
Harvestec
•In order to get a short stubble height the angle of the
header must be adjusted which can result in the
chopper contacting the ground in rolling field conditions

11. Residue from Harvestec 6308C
This picture below shows the stalk residue output after being harvested with a Harvestec 6308C chopping corn
head. This demonstrates the ability of the chopping ability of the Harvestec to leave 2” to 4” residue pieces
consistently in the field. These residue chunks will also have the crimps from the Harvestec serrated knive edges
which accelerates the microbial breakdown process faster than any corn head in the industry.

12. Harvestec does a consistent chopping job
This picture shows the consistent chopping job the forward mounted chopper on the Harvestec
chopping corn head across the entire field.

13. Competitive unit’s residue
This picture shows a competitive rear mounted chopper which shows a lot of stalks that are not
completely chopped and several stalks just pushed over instead.

14. Snout Design
Poly Snout Design
•The teardrop shape of the Harvestec poly
snout delivers the stalk smoothly to the
snapping rolls, stands up down stalks, and
minimizes ear bounce compared to
competitors
•This shape is well suited to following curved
rows compared to competitor’s longer
triangular shaped snouts
•The ribbed shape enhances material flow
over the snout surface causing less drag
•The ribbed shape also strengthens the
snout structure
•Traditional Harvestec white colored snout
offer industry leading visibility when
harvesting at night (colored snouts are also
available)

15. Visibility
This picture shows the view of the standard white colored snouts on the Harvestec header which
really helps visibility later in the day or at night time helping the operator stay on the row.
