NOTE: Be sure to route the cable and tie it down so that pinching or rubbing against sharp edges cannot damage it. Installing Fan Speed Sensor and Cable Parts required for this procedure: Fan speed cable Cable ties Fan speed sensor and sprocket Step-by-Step Procedure NOTE: These machine models ( ) do not have a fan speed sensor, which is needed for the Ag Leader yield monitor. The sensor part number through your John Deere dealer is Part Number AH Other parts from the newer models may also be used depending on the model of your machine which include the sprocket or wheel and a bracket to hold the sensor. Double check the machines fan configuration and shaft diameter before purchasing the parts. The sprocket that is used does not need to have the same number of teeth as the newer models. The number of teeth of the sprocket can be changed in the monitor. 1. Become familiar with how the sensor is configured on a newer machine and purchase the proper parts to install a fan speed sensor. See Figure7 to see the location of a fan speed sensor on a newer model machine. 2. Once the sensor is installed, install the two-connector end of the fan speed cable, to the jumper between the existing wiring harness and fan shaft speed sensor. 3.

15 Cotton Picker Installation Installing Header Height Sensor Parts required for this procedure: Header height sensor assembly (with integral cable) Two 5/16 x 1 inch bolts with lock washers and nuts Arm assembly (threaded rod with S-hook) Anchor spring with S-hook Cable ties Step-by-Step Procedure NOTE: Machine models may vary from the instructions below. The sensor should be mounted to get good range of motion as the header is raised and lowered and not to be in the way or damaged when the header is fully raised. 1. Position the header sensor under the cab so that: 1a. The sensor is mounted on the right most support member where the brake master cylinder is attached. The middle slot of the header sensor will be positioned on the existing hole of support member. Mark the position of the forward slot on the sensor. 1b. While holding the sensor in place, temporally insert the threaded arm into the shaft to verify there is no interference. 2. Drill a 3/8 inch hole, on the mark made in Step 1a. See Figure 9. Existing Hole Drilled Hole Brake Master Cylinder Figure 9. 3/8 inch hole drilled on support member. 9-11

IMPORTANT: Ensure the chain will be clear of the rotating shafts and does not pull on the rod at an extreme angle. 8. It may be necessary to bend the threaded rod to prevent interference with other components. 9. Route header sensor cable to the area under the cab to the distribution cable. 10. Connect header sensor cable to distribution cable. Figure 11. S-Hook attached to right-hand row unit. 9-13

18 Cotton Picker Installation Ag Leader Technology Cotton Flow Sensor Installation for IMPORTANT: Flow sensor installation on John Deere pickers is dependent on the type of machine you own. Please carefully read the instructions. Install sensors on the following rows (for a two row monitoring system which has 4 sensors for 4 chutes) based on machine design for best performance. 2-Row: Rows 1 and 2 4-Row: Rows 1 & 4 If there is a different configuration, contact Ag Leader Technology Technical Support at (515) ext. 1. The sensors, together, should monitor complete rows if possible. Care must be taken when selecting chutes since the front or back picking drums of two different rows are often joined by the same chute. For example, a 9950 must monitor the two chutes behind the cab and each chute on the left and right side. This is the only configuration available without monitoring all six chutes. NOTE: The following instructions are for a system monitoring two rows as well as all rows. Use the table of contents below to find the appropriate instructions for the duct you are mounting to. Item Page Installing Cotton Flow Sensors on Ducts General 9-14 Installing on Metal Duct with Ladder 9-20 Installing on Outside Ducts without Ladder

19 Cotton Picker Installation Sensor Installation Overview 1. Each duct requires an Emitter and Detector pair (See Figure 12) to sense the cotton flow as the cotton is blown to the basket. Each Emitter has five individual infrared light emitters within each housing to cover the width of the duct. Likewise, each detector has five individual sensors within each housing to match up across the duct to sense the light from the emitters. Therefore, it is critical to measure accurately. 2. To mount the sensors, use the mounting plate and appropriate template to position the bracket and mark the needed holes. The brackets will be removed and the holes drilled and the opening for the sensors cut. 3. Once the sensors are installed make sure the telescoping lower duct does not block the sensors when head is raised. If this is occurring, remove no more that 3 inches off the top of the lower duct. Some general criteria that should be used when installing on various chutes: Sensor faces must be parallel for proper alignment Sensors must not be on a curved portion of the chute such that there is cotton directly hitting the sensor. This will subject the lens covers to excessive wear. The sensors should be mounted on a portion of the chute that will not conflict with other components, in both transport mode and harvest mode. The sensor should be mounted as high as possible to prevent interference from the telescoping of the chutes as the header is raised and lowered. Use the example provided to calculate the correct amount of spacers needed for each sensor to allow for unparallel chute walls. Always mount the emitter with the correct amount of spacers first, then align the detector to the emitter. A template is provided to assist in sensor alignment. If at all possible try and mount on a chute that the hinged template will fit around. If the hinged template will not work, measure as accurately as possible to align the sensors. See figures 22, 23,

20 Cotton Picker Installation Ag Leader Technology Detector (Back of Chute) Emitter (Front of Chute) Figure 12. Emitter and Detector pair Calculating the shim thickness to compensate for unparallel chute walls First to compensate for unparallel chutes you need to calculate the amount of shims that is needed for each sensor mounting plate. As seen in the Figure 13, several measurements are needed that will be used in the equation below to calculate the thickness of spacers that will be needed. It does not matter where the sensor will be mounted when taking these measurements, all that matters is the length (L) is from the bottom to the top measurement. The slope or angle of the chute will be the same from the top to bottom. Refer to Figure 13 to take the top measurement and subtract it from the bottom measurement. Multiply the remainder times 3. Divide the product by the length. The last box on the right is the total thickness of spacers needed under the bottom of the mounting plate for each sensor. Note there is already a 0.12 inch spacer welded to the mounting plate. Therefore you want to subtract 0.12 inch from the value you calculate in the right box. Top Bottom = X 3 = /L = inches For example: Refer to Figure 14, you determine that you have a top measurement of 10 inches, a bottom measurement of 6 inches and a length of 48 inches. In this example you would have to have spacers up to 1/4 inch on each sensor. ( = approximately 1/8 [0.125] inch needed) NOTE: It does not matter where the sensor will be mounted when taking these measurements, all that matters is the length (L) is from the bottom to the top measurement. The slope or angle of the chute will be the same from the top to bottom = 4 X 3 = 12 /48 = 0.25 or 1/4 inch As seen in Figure 15, the spacers can be strips of aluminum or metal or washers stacked to achieve the desired thickness. 9-16

23 Cotton Picker Installation Illustrating the importance of aligning the detector from the emitter. The detector should always be aligned from the emitter. The figures below illustrate this. Since the detectors are aligned from the emitters, the emitters must be mounted first. The emitters should be mounted on the front of the chute. The straight line from one sensor to the other represents a light beam. Figure 16: Illustrates correct alignment. Figure 17: Illustrates the detector aligned from the emitter. The detector is mis-aligned but will still correctly work. Figure 18: Illustrates the emitter aligned from the detector. If the emitter is not very accurately mounted, a small amount of unparallelism can result great misalignment. Figure 16. Correct alignment of sensors, Detector aligned from Emitter Figure 17.

24 Cotton Picker Installation Ag Leader Technology Installing on Metal Duct with Ladder Use where applies NOTE: The instructions below may or may not be used depending on the configuration and model of your machine. The general concept of the installation can be derived. Before removing the ducts from your machine, decide where you want to mount the sensors. Keep in mind you want the sensors as high as possible to avoid conflict with the telescoping portion of the chute. At the same time, be careful there are no interferences with any other components. 1. Make a mark on the front side of the chute where you want to mount the sensor. Make the mark where the top of the sensor mounting plate will be positioned. See Figure 21 for the bracket and its orientation. 2. In order to use the hinged template on the metal ladder duct, you must remove a small portion of the sidewalls of the ladder. Make a mark on each sidewall from the mark you made in the previous step. Using a square, connect the marks with a straight line, parallel to the lower end of the duct. 3. From this mark measure down towards the bottom of the duct 5 inches as shown in Figure 20. Using a square extend these marks along the outside of the ladder rail. Using a cutting tool, cut along your marks to remove the 5-inch section of each ladder rail shown in Figure 20. Cut the sidewalls all the way to the surface of the ladder that is attached to the duct so there are no sidewalls remaining in this 5-inch section. 4. Center one of the replacement ladder rails in one of the holes you just cut as seen in Figure 21. Center the cut section with the replacement rail and mark and center punch the four holes for the replacement rail. Do this on each side of the ladder. Using a 9/32- inch drill bit, drill all four holes on each side of the ladder. Once holes are drilled, set replacement rails aside. You will bolt them in at the end of this installation. 9-20

25 Cotton Picker Installation Mark at top of sensor mounting plate 5 inch measurement Figure 19. Mark at top of sensor mounting plate Figure inch measurement on ladder 5. Line up the top of a mounting bracket on the duct with the line and top rail cuts on the ladder (See Figure 21). Orient the bracket so the studs on the bracket are toward the outlet of the duct (up). Center the mounting bracket side-to-side on the duct by accurately marking a vertical centerline on the duct and positioning the center holes of the mounting bracket over the centerline. Figure 21. Orienting the bracket 9-21

26 Cotton Picker Installation Ag Leader Technology 6. Using duct tape, fix the position of the centered mounting bracket for marking the cutout hole and mounting holes. 7. Mark the center rectangular cutout and center punch the six mounting holes to be drilled. 8. Remove the mounting bracket and drill the six center-punched holes with a 9/32-inch drill bit. 9. For cutting the rectangular opening, it is recommended to use a high-speed air, electric cutting disk or plasma cutter. Saber and jigsaws are not recommended. They do not result in a clean cut. IMPORTANT: It is highly recommended to use the cutting tools stated. However, if a jig saw or a torch is used, you should take extreme caution that the edge of the duct and ladder is not bent and rough as cotton will catch and result in error from stringers. CAUTION: To prevent injuries to yourself or others wear safety goggles or face shield for protection from airborne metal particles while cutting. 10. When cutting and drilling is complete use a flat file to remove all sharp edges around the perimeter of the rectangular cutout and carefully file off sharp burrs around drilled holes. IMPORTANT: There must be absolutely NO burrs, as they will create cotton stringers that may affect yield accuracy. 11. Use six of the 1/4 x 3/4-inch truss head screws and six nuts to fasten the mounting bracket to the duct. NOTE: The nuts should be on the outside of the hood so it doesn t protrude into the flow of the cotton. If bolts are installed wrong, errors could be caused in yield data. 9-22

27 Cotton Picker Installation Figure 22. Attaching hinged template 12. Once the mounting bracket is securely fastened to the front side of the duct, attach the hinged template to the mounting bracket as seen Figure 22. Make sure the hinged template is pushed all of the way down into the hinge and using two nuts securely fasten the template to the mounting bracket. 13. Attach the second mounting bracket to the template flat strap using two more nuts as shown in Figure 23. Exploded View Assembled View Figure 23.

28 Cotton Picker Installation Ag Leader Technology 14. Slide the assembly seen in Figure 23 onto the U-shaped strap as seen in Figure 24. The template assembly should be slide on until it mates up with the duct. 15. After marking the holes and rectangular opening, remove the mounting bracket, center punch the holes, and drill the six centerpunched positions with a 9/32-inch drill bit. 16. For cutting the rectangular openings, it is recommended to use a high-speed air, electric cutting disk or plasma cutter for metal ducts. IMPORTANT: It is highly recommended to use the cutting tools stated. However, if a jig saw or a torch is used, you should take extreme caution that the edge of the duct and ladder is not bent and rough as cotton will catch and result in error from stringers. CAUTION: To prevent injuries to yourself or others wear safety goggles or face shield for protection from airborne metal particles while cutting. 17.

29 Cotton Picker Installation Figure 24. Holes ready to be marked 18. Attach the mounting bracket using six 1/4 x 3/4-inch truss head screws. You may want to double check for alignment using the templates before securely fastening all screws. NOTE: Ladder rails may need to be modified or substituted with your own plates, as these rail replacements are for late model machines. 19. Put the replacement ladder rails in place. Fasten the ladder rails using three 1/4 x 3/4-inch truss head screws and three lock washers and nuts. Do not place a bolt in the hole as indicated in the Figure 25. You will install a shield later that will utilize these holes. Repeat this to fasten the second ladder rail. Refer to Figure 25 to see the overall final installation with ladder rails and emitter in place. Do not place bolt in this hole. Both sides. Figure 25. Emitter installed in ladder 9-23

30 Cotton Picker Installation Ag Leader Technology Installing the sensor shield NOTE: This shield is designed for late model machines, some modifications or deviations from these instructions may be needed. 20. Use the 1/4 x 1-inch bolts as studs for the shield to pivot on. Follow the steps below carefully as it can be a little tricky installing the bolts and shield due to the width of the shield and the length of the bolts. See Figure Place a 1/4 x 1 inch bolt into the holes of the replacement rails that you left empty earlier (See Figure 25 & 26) and screw a nut partially onto the bolt. 22. Slide the bottom hole of the shield (oriented as shown in Figure 27) onto the bolt that is on the outside of the nut you just screwed on. Once the shield is on this stud, tighten the nut against the ladder rail to fix the bolt. 23. Repeat Step 21 and 22 for the other side of the rail as seen in Figure Screw the nylock nuts on the end of the studs until the shield is at an acceptable tightness. See Figure After the mounting brackets and replacement rails are securely fastened, place the sensors into the hinges to check for interference. Hinge up and fasten the captive nuts. The emitter (sensor with cable) should be mounted on the front side of the ducts (closest to the cab). 26. Remove the sensors (to prevent damage) and re-install the duct back on the machine. 27. Use the provided RTV silicone to seal the gaps between the mounting plates and the chute. Figure 26. Sensor Shield installed (Side View) 9-24

39 Cotton Picker Installation John Deere Installing Flow Sensor Cable Parts required for this procedure: Flow sensor Cable Harness Static Grounding Cable (9970 and 9976 ONLY) Cable Ties Step-by-Step Procedure 1. The flow sensor cable is constructed to connect to each of the Detectors in series beginning with the left-most duct. (See Figure 37) Locate the end of the cable that has connectors located approximately every 4 feet. Mate the last 9-pin connector with the mating connector on the detector mounted to the left-most duct. (The machines left) 2. Connect each of the Detectors from Left to Right on the machine. The yield monitor will refer to each sensor by the same number that corresponds to the number of row picking unit. 3. Connect the cable attached to the emitter to the mating 4-pin connector on the flow sensor cable at each sensor location. 4. Secure the flow sensor cable to the mounting tube that fixes the position of the ducts. 5. Route the flow cable to the distribution cable under the cab securing it at 18-inch intervals, away from any moving parts. 9-33

40 Cotton Picker Installation Ag Leader Technology Figure 37. Flow Sensor Cable Final Inspection Installation is now complete. Do a walk around of the machine and complete the following: All cable connections have been made. Excess cable has been tied out of the way, so there is no potential interference. All tools have been removed from the machine. All cap screws and captive nuts are tight on the sensor mounts. When header is raised, ensure that the lower telescoping duct does not block the sensors. 9-34

41 Cotton Picker Installation John Deere Operational Checkout Step-by-Step Procedure Refer to the Display Items section in the Operation Section for instructions on how to display different items on the screen. 1. Start engine. 2. Verify the monitor powers up/down properly. 2a. Turn the monitor power switch ON and verify the monitor powers up properly. NOTE: The monitor will power up, check a box for each sensor detected and display the harvest screen of four selected items. If sensors cannot be located, confirm the machine setup is correct by referring to Vehicle Setup in the Operator's Manual. If the problem continues refer to "Monitor Does Not Find Correct Number of Flow Sensors on Initial Power Up" in the Troubleshooting Section of this manual. 2b. Turn the monitor power switch OFF and verify the monitor powers down properly. NOTE: When the power switch is turned OFF the monitor will not immediately turn OFF. The screen will display "Now Archiving Data " "Monitor will automatically power down when complete". If the monitor does not power up/down as described, re-check the cable connections. 3. Display Fan Speed on the screen. 3a. Verify that Fan RPM stays at zero with the Fan OFF. 3b. Engage the fan and verify the monitor measures fan RPM. It should increase as the engine speed engine increases all the way too full engine speed, if not re-check cable connections. 9-35

42 Cotton Picker Installation Ag Leader Technology NOTE: RPM may NOT be accurate, because fan pulses/revolution have not yet been set for your machine. 4. Display "Ground Speed" on the screen. Move the machine slowly to verify the monitor measures MPH at low speeds (below 1 mph). NOTE: MPH will NOT be accurate, because the monitor has not yet been calibrated to your machine. 5. Start the fan blower with the machine at rest and verify that the monitor reads 0.0 MPH. 6. Display "Head Height" on the screen. 6a. Lift the head and verify the head height number increases. Lower the head and verify the head height number decreases. (If it increases instead of decreases, or vice versa refer to the Operator's Manual to change the setup on the monitor.) 6b. Adjustment of chain length and bending of threaded arm may be required to get full range of the header height sensor. 7. Check for acceptable sensor signal strength. 7a. Press the MENU key, DIAG, and Signal Strength. Verify the signal strengths are not less than b. Adjust sensor mounting position to achieve acceptable signal strength. Refer to the Setup Section of the Operator s Manual to adjust the monitor to your machine. NOTE: You may have some hardware leftover. Some of the additional hardware may include replacement ladder rails and aluminum shims. (The shims are only needed for mounting behind the cab of a 9976.) If there is a possibility you left out the shim during installations. Double-check the relevant instructions. Additionally, if you have a 2-row system, you will have extra 5/16-inch bolts. *** 9-36
