1 Safety 1.1 Safety Alert Symbols This safety alert symbol indicates important safety messages in this manual and on safety signs on the header. This symbol means: • ATTENTION! • BECOME ALERT! • YOUR SAFETY IS INVOLVED! Carefully read follow safety message accompanying this symbol.
SAFETY 1.2 Signal Words Three signal words, DANGER, WARNING, and CAUTION, are used to alert you to hazardous situations. The appropriate signal word for each situation has been selected using the following guidelines: DANGER Indicates an imminently hazardous situation that, if not avoided, will result in death, or serious injury. WARNING Indicates a potentially hazardous situation that, if not avoided, could result in death, or serious injury.
SAFETY 1.3 General Safety CAUTION The following are general farm safety precautions that should be part of your operating procedure for all types of machinery. Protect yourself • When assembling, operating, and servicing machinery, wear all the protective clothing and personal safety devices that COULD be necessary for the job at hand.

6 Operating the Header Satisfactory operation of the header in all situations requires making proper adjustments to suit various crops and conditions. Correct operation reduces crop loss and increases productivity. As well, proper adjustments and timely maintenance will increase the length of service you receive from the machine. The variables listed below and detailed on the following pages will affect the performance of the header.
OPERATING THE HEADER 6.1.1 Adjusting Header Float DANGER Stop engine and remove key from ignition before leaving operator’s seat for any reason. A child or even a pet could engage an idling machine. Check the float by grasping the front corner of header and lifting. The force to lift should be 95–105 lbf (426–471 N), and should be approximately the same at both ends.
OPERATING THE HEADER 6.2 Roll Gap Steel "n" bar rolls "condition" the crop by crimping and crushing the stem in several places. This allows moisture release for quicker drying. The degree to which the crop is conditioned as it passes through the rolls is controlled by roll gap.
OPERATING THE HEADER 5. Inspect roll gap at both ends of the rolls. Gap (B) should be 0.5 in. (12.7 mm). IMPORTANT Roll timing is critical when the roll gap is decreased because the bars may contact each other if the timing is wrong. 6.
Page 79
OPERATING THE HEADER 4. Loosen upper jam nut (A) on both sides of conditioner. 5. To increase roll gap (increase conditioning action), turn lower nut (B) clockwise. 6. To decrease roll gap (reduce conditioning action), turn lower nut (B) counterclockwise. 7.
OPERATING THE HEADER 6.3 Roll Tension The roll tension (the force holding the rolls together) is achieved with a spring type adjustable linkage that is preset to maximum at the factory. Heavy crops or tough forage that tend to separate the rolls require the maximum roll tension to ensure that material is sufficiently crimped.
OPERATING THE HEADER 6.4 Roll Timing For proper conditioning, the rolls must be properly timed with each steel bar on one roll centered between two bars of the other roll as shown. The factory setting should be suitable for most crop conditions. IMPORTANT Roll timing is critical when the roll gap is decreased because the bars may contact each...
OPERATING THE HEADER 4. Measure the roll timing distance (B) at each end of the rolls. Each steel bar on one roll should be centered between two bars of the other roll so that (B) is approximately equal on both sides of the bar. NOTE: If adjustment is required, see Section 6.4.2 Adjusting the Roll Timing, page NOTE: Roll spacing not to scale in illustration.
OPERATING THE HEADER 6.5 Forming Shields WARNING Keep hands and feet away from discharge opening. Keep everyone several hundred feet away from your operation. Never direct the discharge toward anyone. Stones or other foreign objects can be ejected with force. The position of the forming shields controls the width and placement of the windrow.
Page 84
OPERATING THE HEADER 2. If side deflector attachment is too tight or too loose, tighten or loosen nut (A) as required. Figure 6.11 169455 Rev. E...
OPERATING THE HEADER 6.5.2 Adjusting the Rear Deflector (Fluffer Shield) DANGER Stop engine and remove key from ignition before leaving operator’s seat for any reason. A child or even a pet could engage an idling machine. The fluffer shield or rear deflector slows the crop exiting the conditioner rolls, directs the flow downward, and fluffs the material.
Page 86
OPERATING THE HEADER NOTE: Swath baffle position may need to be adjusted for proper pin engagement. Loosen bolts (A) and adjust bracket (B) and baffle as required. Tighten bolts (A). Figure 6.14 169455 Rev. E...
A flatter angle provides better clearance in stony conditions while a steeper angle is required in down crops for better lifting action. The header angle may be hydraulically adjusted from the windrower cab using the hydraulic cylinder (A)—if equipped—without shutting down the windrower. Refer your MacDon self-propelled windrower operator’s manual. Figure 6.15 169455 Rev. E...
OPERATING THE HEADER 6.7 Cutting Height Cutting height is determined by a combination of the angle of the cutterbar/header and the skid shoe settings. Cutting height should be adjusted for optimum cutting performance without allowing excessive build-up of mud and soil inside the header that can lead to poor crop flow and increased wear on cutting components.
Sudan, Sorghum, Haygrazer, Tall and stemmy 2300–2500 Timothy Dense 2500 Short grass Thin 1800–2000 Disc speeds are set and adjusted from the cab using system controls, without shutting down the windrower. Refer to your MacDon self-propelled windrower operator’s manual. 169455 Rev. E...
Refer to your MacDon self-propelled windrower operator’s manual for changing ground speed. In tough cutting conditions, such as native grasses, the disc speed will need to be increased.
OPERATING THE HEADER 6.10 Double Windrowing If your windrower is equipped with the Double Windrow Attachment (DWA [A]), refer to the MacDon DWA Manual (MD #169216) for operating and maintenance instructions. The manual is shipped with the DWA Kit. Figure 6.18 169455 Rev.
OPERATING THE HEADER 6.11 Tall Crop Dividers (option) The tall crop dividers (one on each end of the header) assist in clean crop dividing and cutterbar entry in tall crops. Tall crop dividers are not adjustable, but can be removed easily. 6.11.1 Removing Tall Crop Divider DANGER Stop engine and remove key from ignition before leaving operator's seat for any reason.
OPERATING THE HEADER 6.12 The Header Pan The header pan is located behind the cutterbar and helps prevent material loss and wrapping in certain crops, such as grass seed, oats, and tall stalky crops. In conditions where more soil and stones are being picked up by the cutterbar, it may be desirable to remove the pan to allow the debris to fall out before being fed into the conditioner.
OPERATING THE HEADER 6.12.2 Installing the Header Pan To install the header pan, follow these steps: 1. Locate pan (B) under header frame and hold in place. 2. Install six 1/2 in. x 1 carriage bolts (A) and flanged lock nuts.
OPERATING THE HEADER 6.13 Haying Tips 6.13.1 Curing A quick cure will maintain top quality because • 5% of the protein is lost for each day hay lies on the ground. • The sooner the cut hay is harvested, the earlier the start for next growth. Leaving the windrow as wide and thin as possible makes for the quickest curing.
OPERATING THE HEADER 6.13.4 Windrow Characteristics Refer to Section 6 Operating the Header, page 67 for instructions on adjusting the header. For best results, a windrow should have the following characteristics: Characteristic Advantage High and fluffy Movement of air through windrow is more important to the curing process than direct sunlight.
OPERATING THE HEADER 6.14 Levelling the Header Windrower linkages are factory-set to provide the proper level for the header and should not normally require adjustment. The float springs are NOT used to level the header. If the header is not level, check the tire pressures on the windrower ensuring they are properly inflated. Refer to your self-propelled windrower operator’s manual.
OPERATING THE HEADER 6.15 Unplugging the Header Follow these steps to remove plugged material from the header: DANGER Stop windrower engine and remove key before removing plugged material from header. A child or even a pet could engage the drive. 1.
