2. OPERATION AND FUNCTION
The MacDon 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). This downward directing action causes
the corn ears (5) to impact the snapping plates (3), detaching the ear from the stalk in the
process. The detached ears are moved rearward by the gathering chains (6) into the auger
trough (7) and are conveyed to the combine feeder house by the cross auger (8). Corn stalks
are discharged downward by the snapping rolls (1,2).
If the corn head is equipped with optional stalk chopper, the stalks are chopped into small
fragments by this chopper, located under the snapping rolls.
Attention!
For safe corn head operation, it is essential to respect the instructions on the use of the
corn head when mounted to the combine. Only qualified operators should operate the
machine.

OPERATION AND FUNCTION
15
Operation
The corn head is driven from the combine feeder shaft through a universal drive shaft. 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.
The auger is chain driven through a torque limiting clutch from the left side snapping unit drive
(or from both sides of large corn heads).
Consider and follow each of the following sequence guidelines before starting operation of
the corn head:
•after a sounding horn start the engine of the combine
•after ensuring that no one is close to the corn head and combine, lower the corn head
into operation position using the combine “lower” function switch
1. Operate the corn head only in the specified harvesting position
2. Engage the combine feeder drive and begin harvesting.
3. Operate at a ground speed that does not exceed that suitable for the combine and corn head
capacity and ground conditions.
4. Perform an emergency stop
During harvesting be aware of unexpected events that may take place requiring immediate
shutdown of the forward movement or combine feeder drive.
Such events could be:
•accident
•foreign materials in the crop (irrigation pipe, gas tube, rocks etc.) which
could enter the corn head
•excessive crop loading (action of torque limiting clutches)
•clogging or blockage
•other breakdown or fault

OPERATION AND FUNCTION
16
The corn head has no specific emergency stop system. The emergency stop is actuated
using the combine systems located in the combine cab. Understand and respect the
relevant instructions of the combine emergency stop procedures as related to the corn
head.
Never leave the combine cab while corn head is in operation.
Non-conforming use:
The corn head is designed only for harvesting in the direction of planting (row
dependent) and for the specified row widths. Harvesting performance can greatly
deteriorate if the corn head is used in other conditions for which it is not intended.
Deterioration in performance can result if:
•The corn head is positioned too high or too low during harvesting
•The corn head is used to harvest crops other than corn or sunflowers when properly
equipped with a sunflower kit.
