PROPER PREDELIVERY OF A NEW JOHN DEERE HEADER IS ONE OF THE MOST IMPOR- TANT FUNCTIONS A DEALER CAN PERFORM. A HEADER PROPERLY DELIVERED WILL SAVE A DEALER MANY HOURS OF SERVICE CALLS AND GIVE THE CUSTOMER A MORE TROUBLE-FREE HEADER; MORE SATISFIED CUSTOMERS— MORE SALES. References to the right-hand and left-hand sides of the header, are determined by facing in the direction the combine will travel when in use. A This safety alert symbol identifies important safety messages in this predelivery instruction. When you see this symbol, be alert to the possibility of personal injury and carefully read the message that follows. When attaching one part to another, put nuts on bolts loosely with lock washers under nuts. Tighten nuts and spread cotter pins after all parts of an as- sembly are together. After the header has been assembled, lubricate all bearings and wearing parts (see PREDELIVERY LU- BRICATION), and clean grease fittings if clogged with paint. When delivering the header to the customer, explain the many attachments which are available for the combine and how they can help make combining eas- ier in certain crop and field conditions. Separate as- sembly instructions for all attachments are provided with the attachments. WHEN DELIVERING THIS HEADER, GIVE THE CUSTOMER THE COPY OF THE OPERATOR'S MANUAL. STRESS THE IMPORTANCE OF THIS MANUAL; IT WILL SAVE TIME FOR BOTH OF YOU. EXPLAIN THE SAFETY FEATURES OF THIS HEADER AND THE IMPORTANCE OF KEEPING ALL SHIELDING IN PLACE.

It is important to check to be certain that the platform is level. Adjust tilt angle of cutterbar for exist- ing crop and ground conditions. See 200 Series Cut- ting Platforms Operator's Manual for these adjust- ments. IMPORTANT: The cutterbar must be unlocked or in the flex position before adjustment of header switches can be completed. 2. Lower platform all the way to the ground. Loosen lock nut (A) and turn adjusting screw (B) until screw touches stop (C). Red range indicator ball must be centered on (0) or zero. 3. Loosen wing nut (A) and rotate turnbuckle (B) to lengthen rod (C) until raise switch clicks. Then rotate turnbuckle one additional turn and tighten wing nut (A). Wt A— Wing Nut B — Turnbuckle C— Rod D— Wing Nut E— Knob 4. Start combine engine and raise platform until the red range indicator ball is on "2". Loosen wing nut (D) and rotate knob (E) counterclockwise until the lower switch clicks. Tighten wing nut. NOTE: To check setting of raise switch, raise plat- form to maximum height and lower hydraulic cylinder safety stop. Push cutterbar up, by hand, at each sensor pad and have another person listen for raise switch to click. If raise switch does not click when cutterbar is pushed up at each sensor pad, continue to lengthen rod (C) until switch clicks. 5. Adjust drop rate valve. See Page 30. NOTE: To readjust header switches for wet ground conditions, reposition raise switch by lengthening the turnbuckle rod several turns. If the platform ,l hunts, " turn drop rate valve adjusting screw in until "hunting" stops or reposition lower switch for a wider operating range. This setting will cause the cutterbar to operate in the lower part of the 4-inch (102 mm) float range. Remember, Shorter Rod Length— Raise switch closes nearer upper stop (dry ground conditions). Longer Rod Length— Raise switch closes nearer lower stop (wet ground conditions). 28 ADJUSTING HEIGHT SENSING HEADER SWITCHES ON 50 SERIES ROW-CROP HEADS IMPORTANT: For the optional automatic header height control to perform satisfactorily, the follow- ing adjustments must be made before the height sensing switches on the row-crop head can be adjusted. Refer to the 50 Series Row-Crop Head Operator's Manual and make the following adjustments. Adjust each row unit for floating operation. Adjust row unit float spring tension for floating operation. Adjust row unit skid shoes for the desired height of cut. Adjust inner gatherer sheet clearance. 1. Raise header to maximum height and lower hy- draulic cylinder safety stop. A CAUTION: Always lower the hydraulic cyl- inder safety stop when working under the header. ft ® "a) \ MSB IP i A— Lock Nut E— Bracket B — Actuating Rod F — Stabilizer C — Adjusting Nut Bracket D— Stop 3. Loosen lock nut (A) on actuating rod (B). 4. Raise row unit to maximum height and turn ad- justing nut (C) on actuating rod until stop (D) lightly rests against row unit bracket (E). Adjust stabilizer brackets (F) on control rod, to maintain rod in a straight line, the length of the header. 5. Tighten lock nut (A) and lower row unit. Repeat procedure for each row unit and retain pin for future use. 6. Adjust row unit float spring tension until the row unit begins to raise from the lower stop or until the row unit can be pushed upward easily (approximately 10-15 lbs. [5-7 kg] at skid shoe), with the header in the raised position. See 50 Series Row-Crop Head Oper- ator's Manual. 2. Align hole in lower actuator arm with matching hole in bulkhead. Secure arm in position with pin. 29 ADJUSTING HEIGHT SENSING SWITCHES— (Continued) A— Turnbuckle D— Adjusting Bracket B— Push Rod E— Raise Switch C— Screw F— Lower Switch (Left-Hand Outer Gatherer Sheet Removed for Illustrative Purposes) 7. Check to be certain push rod tension spring bracket is adjusted up as far as possible, to maintain maximum spring tension. 8. Loosen lock nut and lengthen turnbuckle (A) until push rod (B) activates or clicks the raise switch (E), then rotate turnbuckle one more turn and tighten lock nut. 9. Loosen screw (C) and rotate lower switch ad- justing bracket (D) fully clockwise. 10. Turn drop rate valve adjusting screw out until header "hunts" or cycles up and down. See page 30. Turn adjusting screw in until header stops "hunting", then turn adjusting screw in an additional 1/2 turn. NOTE: After making the initial adjustment on the push rod in step 8, it may be necessary to readjust the header switches to reduce skid shoe pressure when operating in wet soii conditions. To readjust the header switches, reposition raise switch (E) by shortening turnbuckle (A) approximately three turns initially. Check to be certain that the lower switch can still be activated. If lower switch requires readjusting, it may be necessary to repeat step 10 to stop "hunting." NOTE: It may be necessary to further adjust the turnbuckle and the lower switch to achieve proper skid shoe pressure. This setting will cause the row unit to operate in the lower part of the 6-inch (152 mm) range, where skid shoe pressure is less. NOTE: If the float spring attachment is used with automatic header height control, the tension on the float springs must be reduced until the header lift cylinders extend and retract without the front channels opening. See combine operator's manual. 30 ADJUSTMENTS ON SEPARATOR (ALL HEADERS) ADJUSTING DROP RATE VALVE (Header Drop Rate) Jfab'^ ^00' * . I >* >-A The drop rate valve controls the rate of drop of the header. Turn the drop rate valve adjusting screw out until the header "hunts" or cycles up and down. Turn adjusting screw in until the header stops "hunting." Turn adjusting screw in an additional 1/2 turn. NOTE: The initial setting of the drop rate valve adjusting screw is eight complete turns out. ADJUSTING ACTUATING SWITCH CHAIN The actuating switch shuts off the automatic header height control when the header is raised approximately 18 inches (457 mm) above the ground. A chain, attached to the switch, holds the switch closed when the header is raised. NOTE: If the chain is adjusted too long, it will not release the actuating switch and the automatic header height control will not operate. \M2Bi?en A— Correct Length B— Hook If the chain is adjusted too short, the header can be raised manually, but will continue to lower when the lever is released. In addition, if the chain is adjusted too short, the system will not shut off unless the control switch is turned to the "OFF" position. The length (A) of the actuating switch chain should be adjusted to approximately 16 inches ± 1/2-inch (406 mm ± 13 mm). The above specified chain length opens the actuat- ing switch approximately 18 inches (457 mm) above the ground. To adjust actuating switch chain length, note exist- ing position of chain. Remove hook (B) and insert it in the desired link. 31 FUSE The electrical system of the automatic header height control is protected from overload by a 7.5 amp in-line fuse. This fuse is located in the engine compartment next to the firewall. DISCONNECTING AUTOMATIC HEADER HEIGHT CONTROL 82001$: Whenever the header is removed from the combine, the wiring harness for the automatic header height control must be disconnected. If the electrical circuit overloads and blows the fuse, determine the cause by checking for shorted wiring. After correcting the cause, replace fuse. The 7.5 amp fuse for the electrical portion of the automatic header height control is available as Part No. AH80089. IMPORTANT: Be certain to use only a 7.5 amp fuse to protect the electrical system. Serious dam- age can result if a larger fuse is used and a mal- function occurs. To disconnect wiring harness, pull connectors apart and lay harness on feeder house. NOTE: When removing feeder house from separa- tor, disconnect wiring harness, as iilustrated, and re- move harness from clamps on feeder house. Coil harness and store under operator's platform for future use. To disconnect the actuating switch chain, remove the chain attaching hook on the upper left-hand side of the feeder house. 32 PREDELIVERY LUBRICATION CUTTERBAR DRIVE CASE Use only John Deere SAE HD 90-140 Gear Lubri- cant or an equivalent SCL multipurpose-type gear oil in the gear case. Other types of oils will not give satis- factory service and may result in eventual damage. This special oil, available from your John Deere dealer, may be used in all types of weather conditions. CORN HEAD GEAR CASES Use John Deere case lubricant or its equivalent (type "0" [zero] extreme pressure). This lubricant is available in a 14-1/2-oz. (0.4 kg) tube AN102562, or a 35-lb. (16 kg) pail AH80490. GREASE FITTINGS SYMBOLS Lubricate with John Deere Multi-Purpose lu- bricant or an equivalent SAE multipurpose- type grease at hourly intervals indicated on the symbols. £l CAUTION: Never lubricate or service com- ** bine or engine while it is running. NOTE: Shields are removed, where necessary, for illustrative purposes only. Remove dirt and paint from grease fittings and noz- zle of grease gun before lubricating. Replace all missing or broken grease fittings imme- diately. Lubricate all parts thoroughly with John Deere Multi-Purpose lubricant or an equivalent SAE multi- purpose-type grease but avoid excessive lubrication. Excess lubricant will drop onto belts causing slippage. Put a few drops of SAE 30 oil on all clevises, linkages, and other moving parts. CLEVISES, LINKAGES, AND OTHER MOVING PARTS When lubricating the header, make a practice of putting a few drops of SAE 30 oil on all clevises, linkages, and other moving parts. This will make them work easier and prolong their life. CHAINS Lubricate chains every 10 hours of operation with SAE 30 or heavier oil. Run chain for a few minutes before lubricating. A warm chain increases the pene- tration of the oil into the bushings. Shut off combine engine and then lubricate chains. CAUTION: Never lubricate chains with the combine engine running. Run the chain after lubricating to assist distribution and penetration of the oil. Make a practice of checking chain tension at this time. 33 200 SERIES CUTTING PLATFORM LUBRICATION Knife Slat Reel Shaft— Both Sides The amount of lubricant to use on a knife depends on the conditions in which the work is being done. When the grain is being topped and the cutterbar is carried some distance from the ground, liberal lubrica- tion with SAE 30 oil is permissible, In conditions where the cutterbar must operate close to the ground, it is better not to use oil except for a small amount on the hold down clips. 10-HOUR LUBRICATION Knife Head (L.H.

Proper delivery should be an important phase of a dealer's program. Many complaints arise simply because the owner is not shown how to operate and service the new com- bine or header properly. Enough time should be de- voted, at the customer's convenience, to introducing the new combine or header and explaining how to operate and service it. Use the operator's manual as a guide and be certain the owner understands these points thoroughly. 1 . The importance of safety. 2. The importance of lubrication and periodic ser- vice. 3. Controls and instruments. 4. How to start and stop the engine. 5. All functions of the hydraulic system. 6. Transporting. AFTER-SALE INSPECTION The purchaser of a new John Deere combine or header is entitled to a free inspection by the dealer at some mutually agreeable time within the operational season. The purpose of this inspection is to make certain that the customer is receiving satisfactory performance from the combine or header. The inspection should reveal whether or not the machine is being operated, lubricated, and serviced properly. With this recommended after-sale service inspec- tion, you may eliminate needless service work by pre- venting minor irregularities from developing into serious problems later. This will promote strong dealer-customer relations and present you with an opportunity to answer questions that may have arisen. Use this inspection period to acquaint the customer with any special attachments which will help him to do a better job with his machine. 37 MEMORANDA ^ *Sw Litho in U.S.A.
