  • Page 13: Operation And Function

    OPERATION AND FUNCTION 2. OPERATION AND FUNCTION The Harvestec corn head can be mounted on most combines. 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 combine feeder shaft through a universal drive shaft or chain shaft coupling. Power is transmitted from the drive shaft by gears encased in an oil bath to a shaft which passes through the snapping unit. Torque limiting clutches transmit power from the 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.

    RUN-IN PROCEDURE 6. RUN-IN PROCEDURE A 20 minutes “trial run” is suggested after the initial mounting. Prior to the trial run, perform a full lubrication procedure as described in Section 1 "Maintenance and Lubrication”. Gearboxes are filled with lubricant at the factory but levels should be checked before beginning the trial run.

  • Page 29: Setup Procedure And Adjustment Of The Corn Head

    SETUP PROCEDURE 7. SETUP PROCEDURE AND ADJUSTMENT OF THE CORN HEAD 7. 1. Frame The corn head is provided with parking stands which must always be used when it is to be disconnected from the combine. Before detaching the corn head from the combine, adjust the parking stand position such that the distance between the ground and the lower support of the corn head is about 30 cm (12 inches).

  • Page 30: Auger

    SETUP PROCEDURE 7.2. Auger The auger is driven through a torque-limiting clutch that can disengage excessive loads on the drive. This clutch is located on the left-hand side, but an additional clutch is located on the right hand side on larger corn heads. In some conditions it may be necessary to change the speed of the auger.

  • Page 31: Input Gearbox Drive

    SETUP PROCEDURE 7.3. Input Gearbox Drive The input gearboxes are connected by a double joint coupling drive or shaft (1) depending on the combine. The gearbox assemblies (2) are selected to provide a nominal snapping unit input speed of 550 rpm for each combine. Gearboxes can be exchanged as necessary.

  • Page 32: Snapping Units

    SETUP PROCEDURE 7.4. Snapping units 7.4.1. Snapping rolls adjustment Three important settings must be observed when installing or adjusting the snapping rolls. 7.4.1.1. Distance between snapping roll shafts Adjust the shafts parallel to each other by setting 62 mm (2.45”) between the two bearing housings as shown in the illustration below.

  • Page 33: Snapping Plate Adjustment

    SETUP PROCEDURE 7.4.1.3. Alignment The front bearing support is mounted to the snapping roll frame with slotted holes. Set the rolls in line as shown below. Correct Incorrect Knife 7.4.2. Snapping plate adjustment The nominal factory setting is 27 mm (1-1/16”) at the front and 32 mm (1-1/4”) at the rear. For proper operation, the snapping plate gap should be 5 mm (3/16”) tighter at the front than at the rear.

  • Page 34: Vine Knife Adjustment

    SETUP PROCEDURE 7.4.3. Vine knife adjustment The gap between the vine knives and the stalk rolls should not exceed 0.5 mm (.02”). This gap should be set on one rib and all rib clearances should be checked by the rotation of the rolls to ensure there is no interference.

  • Page 35: Gearbox Timing And Backlash Adjustment

    SETUP PROCEDURE 7.4.5. Gearbox timing and backlash adjustment Snapping roll gear timing is done by visually aligning the hex shafts as shown below. The backlash can be determined by rotating one gear relative to the other. There should be 1° of free rotation between the gears.
