  • Page 13 2. OPERATION AND FUNCTION Function The Harvestec corn head can be mounted on most combine makes, for harvesting corn in row spacing from 50cm (20”) to 100cm (40”). Corn ears are detached from the corn stalks as is shown on the illustration below. The corn stalk enters the area between the snapping rolls (1,2) which counter-rotate relative to each other, and are pulled downwards between the snapping plates (3) by the rolls (1,2).
  • Page 14 OPERATION AND FUNCTION Operation The corn head is driven from the drive shaft of the combine feeder house through a universal drive shaft or chain shaft coupling. Power is transmitted from the drive shaft by a chain encased in an oil bath to a through shaft of the snapping units. Torque limiting clutches transmit power from the through shaft to each snapping unit.
  • Page 15 OPERATION AND FUNCTION The corn head has no specific emergency stop system. The emergency stop is actuated using the combine systems located in the combine operator’s cab. Understand and respect the relevant instructions of the combine emergency stop procedures as related to the corn head and its drives.

  • Page 30 HARVESTING To adjust the auger, loose the 3 hex. nuts (2) and use the hex. head bolt (3) to move the auger into adequate position. There is an access window (4) in the frame to ease the adjusting procedure. If you want to lift the auger without rearward movement, use only one bolt (5) in the medial hole of the bracket (6) to enable the whole assy to turn around this axis.
  • Page 31 HARVESTING 7.3. Chain Case Drives Sprockets are installed at the factory to match the combine mounting kit such that the speed of the snapping unit input shaft is about 500 rpm. This sprocket selection should provide optimum performance in normal conditions. Replaceable sprockets are available to permit change of speeds to satisfy varying harvesting conditions Do not over tighten the drive chain.
