Page 16: Operation And Function
OPERATION AND FUNCTION 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). - Page 17 OPERATION AND FUNCTION 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.
- Page 18 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 cab. Understand and respect the relevant instructions of the combine emergency stop procedures as related to the corn head.

- Page 27 MOUNTING TO THE COMBINE...
- Page 28 MOUNTING TO THE COMBINE The folding corn head hydraulic cylinders should operate in the following sequence: 1. The locking cylinders (D1, D2) must retract fully. 2. The rear divider cylinders (B1, B2) must extend fully. 3. The wing cylinders then fold the wings. If the wing cylinders start before the other cylinders (D1, D2, B1, B2) reach the end positions, then the pressure relief valve adjuster screw should be turned a half turn clockwise.

Page 29: Header Start-Up Procedure
HEADER START-UP PROCEDURE HEADER START-UP PROCEDURE A 30 minute “trial run” is suggested after the initial mounting. Start the combine and momentarily engage the drive with the engine speed at low idle, If all sounds well, run the corn head slowly. Avoid starting the drive at high engine speed as the inertia load from acceleration can be 8-10 times more than the load from steady speed operation. -

Page 44: Stalk Chopper
HARVESTING 7.1. Stalk chopper The stalk chopper (1) cuts the stalks directly under the snapping rolls (2) with special knives. The stalk chopper drive can be disengaged by turning the hex knob (3) 180 degrees. Then chopper knives can be reversed to extend life. When knife replacement is necessary replace the bushings, bolts and nuts. -
Page 45: Row Spacing Adjustment
HEADER CONVERSIONS ROW SPACING ADJUSTMENT The row unit spacing must match the corn row spacing for optimum performance. This is of greater importance with wider corn heads. Improper matching can result in premature wear of the snapping roll front supports and the leading edge of the snapping plates. The row unit spacing is set from the factory and is not designed to be adjusted afterwards. -
