Page 72: Header Operating Variables
OPERATION 3.7 Header Operating Variables Satisfactory header function requires making adjustments to suit various crops and conditions, reduce crop loss, and increases productivity. The variables listed in Table 3.5, page 54 allow the operator to affect the header performance. You will quickly become adept at adjusting the machine to achieve the results you desire. Most of the adjustments have been preset at the factory, but the settings can be changed to suit crop conditions.
Page 73 OPERATION DANGER To prevent bodily injury or death from the unexpected start-up of the machine, always stop the engine and remove the key from the ignition before leaving the operator’s seat for any reason. 1. Raise the header so the stabilizer wheels are off the ground. 2.
Page 74 OPERATION 13. Lower the header to the desired cutting height using the combine controls and then check load indicator (A). Figure 3.27: Load Indicator IMPORTANT: Continuous operation with excessive spring compression (that is, the load indicator reading greater than 4 or compressed length [A] less than 295 mm [11 5/8 in.]) can result in damage to the suspension system.
Page 75 OPERATION Adjusting Stabilizer Wheels A properly adjusted header will achieve a balance between the amount of header weight carried by the float springs and the amount carried by the stabilizer wheels. DANGER To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key from the ignition before leaving the operator’s seat for any reason.
Page 76: Cutting On Ground
OPERATION 7. Position the header at the desired working angle. If the header angle is not critical, set it to mid-position. IMPORTANT: Continuously operating the stabilizer wheel while the spring is highly compressed can result in permanent damage to the stabilizer wheel suspension system. The spring is considered to be highly compressed when the load indicator shows a reading greater than 4 or when compressed length (A) is less than 295 mm [11 5/8 in.]).
Page 77 OPERATION 5. Remove lynch pin (A). 6. Hold shoe (B) and remove pin (C) by disengaging it from the frame and pulling it away from the shoe. 7. Raise or lower skid shoe (B) to achieve the desired position; use the holes in support (D) as a guide. 8.
Page 78: Header Float
OPERATION 3.7.2 Header Float The header float system reduces the ground pressure at the cutterbar, allowing the header to follow the ground and respond to sudden elevation changes or obstacles. The header float is indicated on float indicator (A). Values 0 to 4 represent the force of the cutterbar on the ground, with 0 being the minimum and 4 being the maximum.
Page 79 If an adequate header float setting cannot be achieved using all of the available adjustments, an optional heavy-duty spring is available. See your MacDon Dealer or refer to the header parts catalog for ordering information. 1. Park the combine on a level surface, and lower the reel fully.
Page 80 OPERATION 6. Place wing lock spring handles (A) in the upper (LOCK) position. Figure 3.38: Wing Lock in Lock Position 7. Ensure that both header float lock levers (A) are in the down (UNLOCK) position. Figure 3.39: Header Float Lock in Unlock Position 8.
Page 81 OPERATION 9. Remove torque wrench (A) from its storage position on the right side adapter frame. Move the torque wrench slightly in direction shown to disengage the wrench from the hook. Figure 3.41: Torque Wrench 10. Place torque wrench (A) onto float lock (B). Note the position of the torque wrench for checking the left or right side of the adapter.

Page 83 OPERATION 17. Return torque wrench (A) to its storage location at the right side of adapter frame. Figure 3.46: Torque Wrench 214323 Revision B...
Page 84: Locking/Unlocking Header Float
OPERATION Locking/Unlocking Header Float Two header float locks (one on each side of the adapter) lock and unlock the header float system. IMPORTANT: The float locks must be engaged when the header is being transported with the adapter attached so there is no relative movement between the adapter and the header.
Page 85: Operating In Rigid Mode
OPERATION 1. Move spring handle (A) in the lower slot to unlock the wing. The unlocking should be audible. 2. If the lock link does not disengage, move the wing by raising and lowering the header, changing the header angle, or driving the combine until it disengages.
Page 86: Checking And Adjusting Header Wing Balance
OPERATION 1. Move spring handle (A) in the upper slot to lock the wing. The locking should be audible. 2. If the lock link does not engage, move the wing by raising and lowering the header, changing the header angle, or driving the combine until it engages.
Page 87: Checking Wing Balance
OPERATION The header wing balance allows the wings to react to changing ground conditions. If set too light, the wings will bounce or not follow ground contours, leaving uncut crop. If set too heavy, the end of the header will dig into the ground. After the header float has been set, the wings must be balanced for the header to follow the ground contours properly.
Page 88 OPERATION 5. Remove linkage cover (A) by removing bolt (B) and rotating the cover upward until the inboard end can be lifted off. Figure 3.56: Linkage Cover NOTE: Refer to decal (A) inside each linkage cover. Figure 3.57: Linkage Cover 6.

Page 90 OPERATION 10. Move the wing upward with torque wrench (A) until the pointer lower alignment tab (C) lines up with upper edge of top-link (B). 11. Observe indicator reading (A) on the wrench and record it. Figure 3.62: Balance Linkage 12.
Page 91 OPERATION • If the indicator range is as shown, the wing is too heavy. Figure 3.65: Wrench Indicator 13. Place wrench (A) back onto the right leg of the adapter. Figure 3.66: Torque Wrench 14. Lock the wings by moving spring handles (A) to the upper (LOCK) position.
Page 92: Adjusting Wing Balance
OPERATION 15. Reinstall linkage cover (A) and secure it with bolt (B). Figure 3.68: Linkage Cover Adjusting Wing Balance Wing balance ensures that the left and right wings require the same amount of pressure to follow the ground. The amount of ground force/pressure required to lift the wings, and the speed that wings return to the ground when the pressure is reduced should be equal/balanced.
Page 93 OPERATION 5. Remove linkage cover (A) by removing bolt (B). Figure 3.70: Linkage Cover NOTE: Refer to decal (A) inside each linkage cover. Figure 3.71: Linkage Cover 6. Unlock the wings by moving handle (A) to lower (UNLOCK) position. Figure 3.72: Wing Lock in UNLOCK Position 214323 Revision B...
