Features

Features

  • A light yet robust frame structure and new row units reduce weight.
  • High performance snapping rolls feature 4 hardened carbide knives bolted to each snapping roll shaft for easy replacement.
  • Exclusive serrated edges between the knife blades provide 8 pinch points on the stalk per revolution of roll. This results in less trash intake and stalk slippage than most competitors with just 4 pinch points.
  • Knives can be reversed when the front edge wears to prolong life & reduce operational costs.
  • Each front-supported snapping roll uses two sealed double row ball bearings. The grease in the cavity forms a barrier to prevent dirt & debris from contacting the bearing seal. The greasing interval is weekly or every 50 hours of operation, far greater than most of our leading competitors.
  • The reduced frame weight, high performance snapping rolls, aluminum row unit gearboxes and compact driveline requires less horsepower from the combine resulting in reduced fuel consumption.
  • The compact aluminum row unit gearbox is protected by a Walterscheid radial pin safety clutch.
  • The gathering chain driver sprockets are replaceable as a single piece. These sprockets have a special tooth profile that protects the gathering chain if the chain meets an obstruction. This also helps to protect the row unit driveline.
  • Chopper models feature aluminum stalk chopper gearboxes with a large oil volume to dissipate heat. The optimized position of the chopping knives relative to the snapping rolls ensures excellent chopping quality even at higher ground speeds of 7 ½ MPH (12 km/hr).

Options

Options

  • Folding Corn Heads
    • Reduced width means travelling with ease from field to field during harvest time. The folding mechanism operates with push button simplicity right from the comfort of the combine cab. Go from full width to completely folded in less than two minutes.
  • Colored Snouts & Dividers
    • Red, green or yellow snouts & dividers are available as a special factory order.
  • Stubble Stomper
    • The stubble stomper reduced wear on the combine tires.
  • Rotary End Divider
    • The rotary end divider replaces the standard side extension with a hydrostatically driven helix to handle down corn.
  • Harvestec Sunflower Adapter Kit
    • It's easy to set up the corn head for sunflower harvesting with the installation of the Harvestec Sunflower Adapter Kit.

The Agronomically Correct Cornhead



Industry Leading Residue Management

Stalk residue after being harvested with a Harvestec 6308C chopping cornhead. This demonstrates the chopping ability of the Harvestec to leave 2” to 4” residue pieces consistently in the field. These residue pieces also have crimps from the Harvestec serrated knife edges. This accelerates the microbial breakdown process faster than any cornhead in the industry.   Harvestec-20151015-301-WEB

Industry Leading Visibility

The traditional Harvestec white colored snout offers industry leading visibility when harvesting at night, making it easier for the operator to stay on the row. Colored snouts are also available to match the OEM combine color. Harvestec-20151015-235-WEB


Harvestec Competitor
Knife Roll Comparison
  • 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-20151015-165-WEB
  • 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.

Mid-Mount Chopping Rotary Disc Unit Comparison
  • Industry leading 2800RPM chopper speed
  • Optimal front mounted chopper is close to the underside of the rolls providing the shortest, most consistent shortest 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 the shortest stubble height in the industry.
  • Chopper gearbox can be easily turned off

Mid-Mount Design

  • 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

Rotary Disc Design

  • High horsepower required to run
  • Only has good chopping quality in standing green corn when corn is standing up straight
  • Struggles in down corn, twin row corn and tough conditions if the stalk isn’t fed into the center of the row unit
  • Chopping cannot be disengaged

Rear Mount Chopping Comparison
  • Industry leading 2800RPM chopper speed
  • Optimal front mounted chopper is close to the underside of the rolls providing the shortest, most consistent shortest 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.

  • The positioning ensures the shortest stubble height in the industry.
  • Chopper gearbox can be easily turned off
Harvestec-20151015-170-WEB
  • Chopper unit is located on a separate 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
  • Light duty gearboxes compared to Harvestec’s more robust design

Snout Design Comparison
  • The teardrop shape of the Harvestec poly snout (shown in red color option) 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
  • Chopper positioning allows running the snapping unit closer to the ground in down corn conditions without having the chopper touch the ground.
  • 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)
Harvestec-20151015-193-WEB
  • The vast majority of competitors still only offer a smooth rounded shape design which doesn’t stand down corn stalks up causing them to struggle in down corn conditions.
  • The smooth rounded shape is less durable than the strengthened ribbed design of the Harvestec snout design
  • The straight angle of most competitors heads make it more of a challenge to follow curved rows such as pivot planted fields.
  • Harvestec is the only corn head to offer the white colored snouts which offer industry leading visibility when harvesting at night.
