SYSTEM REQUIREMENTS

POWER SUPPLY

The 2940 system uses a switched power source. The 2940-153 will need connected to a switched power source. (Connector to the tractor not included)

SWITCHED POWER SOURCE CONNECTOR PART #’S:

JOHN DEERE P/N: RE67013

CNH P/N: 187103A1

FUSE PROTECTION

To protect the Compressor Assembly from damage always ensure the integrity of the integrated 40 amp and/or 80 amp circuit breaker at the tractor cable where connected to the battery in case of short or over-circuit. When connected correctly, the tractor has a fuse to protect the cab controller located in the tractor’s fuse panel.

AIR COMPRESSOR MAINTENANCE

To prolong life expectancy of compressor, clean filter by removing the element from the housing, and tapping it, exposed side down. This will empty the pleats of the filter of collected dust. If the dust has been wet or will not clean out, call Yetter to order a new element. You may lightly blow out the electronic box using an air tool. The housing and filter should be checked every two days of field operation, or more if conditions are very dusty.

FAILURE TO LINE UP TABS WHEN PLUGGING MALE INTO FEMALE CONNECTORS CAN RESULT IN SHORT CIRCUIT

2940 AIR ADJUST SYSTEM INFORMATION

The 2940 Air Adjust Residue Manager control system consists of five primary components and kits. These parts include; the Cab Controller, the Air Compressor Assembly, Residue Manager Kit, Tank Mounting Kit and the necessary Wires, Air Lines, and Fittings.

CAB CONTROLLER____________________________________________________________

2940-100

The Cab Controller will use the RAM mount provided for installation in cab. Make adjustments quickly and accurately during planting with the cab controller. Adjust up and down pressure to create the ideal “ride” or floating position for residue managers. Lift and down pressure settings can be adjusted independently. Down pressure can be increased to fix row cleaner in the rigid position. Five presets can be programmed within the controller for quick changes. Residue Managers can be raised as needed with a push of a button.

AIR COMPRESSOR ASSEMBLY_________________________________________________

2940 Air Adjust requires a stable air supply

source that can provide 105 psi of clean, dry

air. The ‘clean, dry air’ is a key component of

the air supply, moisture within the air supply

can shorten the life-cycle of the system.

2940 AIR ADJUST SYSTEM INFORMATION

RESIDUE MANAGER__________________________________________________________

WIRE, LINES, AND FITTINGS KIT_____________________________________________

12V-DC cables will be used to power the air compressor, cab control, and dump valves. Flexible tubing will be used to move air from the tank to each air bag. Each kit will include pneumatic lines for both circuits, down and lift, as well as the fittings to make

connections and cable ties to securely fasten the lines to the planter.

Note: All 2940 Air Adjust kits include a tubing cutter within the kit.

The 2940-341 cutter should be used for

every cut to ensure a clean, square cut.

2940 AIR ADJUST ASSEMBLY GUIDE OUTLINE

STEP 1: INSTALLING 2940-100 CONTROLLER

Begin by installing the 2940 Air Adjust by mounting the 2940-100 Cab Controller and 2940-133 RAM Mount within the cab of the tractor. Position the Cab Controller within reach during operation without compromising safety or visibility from the cab. Route the 2940-152 cable from the hitch connecting point to the switch panel.

STEP 2: INSTALLING COMPRESSOR ASSEMBLY AND POWER SUPPLY CABLES

Begin by locating a suitable mounting location for the compressor assembly. Placement of the compressor assembly will vary on the make and model of the planter. Use mounts supplied or depending on application, different mounts may need to be built. NOTE: Be sure to check clearance of compressor assembly in all locations, especially noting tractor tires and folding/unfolding the planter for transport mode and 2-point top link.

STEP 3: RESIDUE MANAGER INSTALLATION

Install the 2940-140 Residue Manager Assembly, securing with mounting hardware and then install Wheel Mount Assemblies. For conventional or larger planters upper holes may be needed. For very shallow planting depths, lower hole settings may need to be used.

STEP 4: CONNECTING & ROUTING AIR LINES

Install the air lines, down (black) and lift (blue) pressure circuits, to the Air Bags. Route the air lines safely from the Air Bags, avoiding rotating parts and pinch points, then connect to the trunk lines on the planter frame. Route the main trunk line in the direction of the compressor unit to connect with to the Compressor Assembly.

STEP 5: DUMP VALVE INSTALLATION

Install the dump valves to the planter as shown in the diagram. Install the wiring harness; route the wiring harness safely from dump valves to the Compressor unit, avoiding rotating parts and pinch points

. Refer to page 46.

STEP 6: PERFORM A PRE-OP TEST OF THE SYSTEM

Now that the system is set up, perform a test of the system. Before performing a test, make sure to fully unfold your planter. Begin a Compressor test, Wiring and Plumbing test, and a Leak test on your system. Refer to page 47.

Refer to page 15.

Refer to the diagram on pages 26-28.

Refer to pages 29-45.

INSTALLING THE CAB CONTROLLER

Step 1: Begin installing the 2940 Air Adjust controller once an adequate mounting

location has been found, fix the base component of the 2940-113 Mounting Bracket in place. Connect the mount bracket to the rear of the controller. Step 2: Attach the male end 2 pin connector of the 2940-153 to the female end 2 pin connector on the 2940-100 cab controller. Install connector not provided for your tractor at the bare end of the 2940-153 and connect to tractors switched power source. The

cigarette outlet is NOT a switched port on all models of tractors, and therefore should not be used.

Convenience port connector part #’s:

JOHN DEERE PART #: RE67013 CNH PART #: 187103A1

Step 3: Route the 2940-152 hitch to switch panel

wire harness from the rear 6 pin connector of the 2940-100 cab controller to the hitch-point at the rear of the tractor.

INSTALLING 2940 AIR COMPRESSOR ASSEMBLY

Begin by mounting the 2940 Compressor:

Step 1: Every planter/tractor combination will contain its own unique situations in regard to mounting the 2940 Compressor Assembly for clearance and accessibility.

YOU SHOULD EXERCISE YOUR OWN BEST JUDGEMENT TO FIT YOUR SITUATION.

Begin by locating a suitable mounting location for the compressor assembly. Placement of the compressor assembly will vary on the make and model of the planter. Use mounts supplied or depending on application different mounts may need to be built. NOTE: Be sure to check clearance of compressor assembly in all locations, especially noting tractor tires and folding/unfolding the planter for transport mode and 2-point top link.

Next, if using the 2940-101 compressor, connect the 2940-150 Compressor Power Cable and 2940-166 VDM Power Cable on the 12V power source from the tractor battery. If using the 2940-103, only the 2940-166 VDM Power Cable will be required to be installed on the 12V power source. After cables are properly installed on 12V power source, safely route the power cables to the rear of the tractor in a manner to protect the cables from heat and any pinch points, securing at rear of tractor. The 2940 Air Compressor Assembly requires mounting with access to 12V power from the tractor. Optional power cable extensions are available. Step 2: Visually inspect the proposed mounting location for structural stability and to find signs of wear in that location. Possible obstructions to be aware of include marker arms, liquid fertilizer tanks, rear tires (duals especially) during tight turns, etc… Step 3: Mark out the position of the Compressor then complete a cycle of folding/unfolding to transport mode and raising/lowering of the planter; as well as, driving in a tight circle in one or both directions, in planting position, to verify or identify obstructions. Step 4: Once the compressor is mounted, repeat the previous process very cautiously to once again verify that the compressor is clear of obstructions.

Use the illustration with dimensions to identify possible mounting locations on your specific planter. Both the 2940-101 and 2940-103 require 4” of clearance from each side. (top, bottom, front, back, both sides)

INSTALLING 2940 COMPRESSOR ASSEMBLY

2940 AIR COMPRESSOR MOUNTING GUIDE

2940-085 mounting kit is designed for mounting to the 2 point cross hitch on the planter, or require greater elevation of the compressor for clearance reasons.

REFER TO PAGE 77 & 78 FOR PART LIST

The most common mounting location for larger planters will be on the draft bar. Use the 2940-086 mounting kit for situations that require mounting elsewhere on the planter than the hitch. This will allow the compressor to be elevated and set back (or forward) to avoid clearance issue.

Installation overview:

1) Prior to installing check the freedom of motion of the row cleaner.

2) The installation process should be done with the planter raised, half folded for

transport, and the row units fully extended down.

3) Install the 2940 Residue Manager Mounting Bracket Assembly centered on the planter row unit with provided hardware.

INSTALLING 2940 AIR ADJUST RESIDUE MANAGER KITS

Step 1: Install the 2940-339 3/8” PTC x 1/8” NPT Male fittings to the Air Bags.

Step 2: Install and secure the Residue Wheel Mount onto the Residue Manager

Main Assembly bracket.

- Recommended starting location is the fifth hole from the top.

For conventional or larger planters upper holes may be needed. For very shallow

planting depths, lower hole settings may be needed.

CONNECTING/ROUTING THE AIR LINES

This procedure should be done with the planter raised, half folded for transport, and the row units and row cleaners fully extended down.

The lines and fittings kit supplied is designed to enable the connection from the 2940 Air Adjust compressor for both circuits (Down and Lift) to the Air Bags.

The primary concern is the security of the lines themselves. The lines should be fastened to the planter in a manner that allows full range of motion/clearance of the row unit. Special caution should be taken with rows at break or fold points of the planter as it folds to and unfolds from transport mode. Extra lengths of air line or alternative routing may be necessary to stay clear of rotating parts and pinch points. See pages 30-44 for planter specific diagrams.

Due to the wide variety of planter/row unit configurations, you should adapt the installation as necessary for your planter. Every planter will contain its own unique situations in regard to routing the lines. You should exercise your own best judgment to fit your situation.

 ALL lines will be 3/8” tubing  Black tubing – used for routing to DOWN pressure  Blue tubing – used for routing to LIFT pressure  Pressure specifications are the same for both colors of tubing  Lines should be placed as efficiently and conveniently as possible  Secure the Air Lines using the supplied zip tie-straps – do not pinch the line

closed when cinching tight

 The air lines should be secured and routed back to the main bar to be Tee’d

into the main trunk lines

 DO NOT pre-cut the line, measure and lay-out each length individually.

After completion of the FIRST row and PRIOR to continuing to other rows, check for clearance of, and lack of pinch points on all lines and fittings. This should be done by completely raising and lowering both the row unit and row cleaner to their extremes, make sure the air lines are not pinched or exposed to wear points throughout the movement of the row unit.

Note: 2940 Air Adjust Residue Managers include a 2940-341 tubing cutter within the kit. This cutter should be used for every cut, to ensure a clean, square cut of the tubing.

AIR LINES ROUTING

On the following pages are diagrams of the Air lines for various planter makes and models

Direction of flow is: from Supply Tank to Lift (Blue) and Down (Black) lines to Airbags all lines will be 3/8”. Route the lines as efficiently and conveniently as possible. Use the air line colors to differentiate the lift pressure (Blue Air Line) and down pressure (Black Air Line) on the planter for trouble shooting, and leak detection.

AIR LINES ROUTING

AIR LINES ROUTING – ROW UNIT

Below is a suggested method for safely and securely routing the air lines from the Air Bag to planter frame. These are generalizations and YOU SHOULD USE YOUR OWN BEST JUDGEMENT in routing air lines.

Specific air line routing will be dependent upon:

* Row unit make (JD, Kinze, CNH, AGCO, etc) * Parallel arm length

DO NOT pass the lines between the rear of the parallel arm and the row unit. This can act as both a pinch point and wear point.

2940 -136 DUMP VALVE KIT INSTALLATION

Install the dump valves to the planter as shown. Install the wiring harness; routing the wiring harness from the dump valves to the Compressor Assembly.

PRE OPERATON TEST CHECK

LEAK TESTING

This leak testing procedure is for the 2940 Air Adjust compressor system consisting of an electric compressor with 20-gal tank, regulator control interface, tubing, and air bags. This procedure shall be performed at the beginning of each season of system use and every 20 hours of in season use. In addition, it should be performed if the user notices a

lack of air pressure availability or if the compressor is running an abnormally high duty cycle. It will help keep the duty cycle in check, thus extending the life of the

compressor.

Leak Testing Procedure:

1. Ensure the Tank pressure is above 90 psi and at least 50 psi is in the Lift circuit.

2. When Tank pressure drops 2 psi, start a timer.

3. Note the Tank pressure in 2 minutes.

4. If the pressure drop is greater than 5 psi, check the Lift pressure plumbing for leaks. Repair as necessary, and test again.

5. Then do steps 1-4 with at least 50 psi in the Down circuit and repair leaks as necessary and retest.

AIR COMPRESSOR PRE-OPERATION TESTING

This testing procedure is for the 2940 Air Adjust compressor system consisting of an electric compressor with 20-gal tank. This procedure shall be performed at the beginning of each season of system use. In addition, it should be performed if the user notices a lack of air pressure availability. It will let the user know if the compressor is in good condition, thus providing adequate pressure supply for the system.

AIR COMPRESSOR PRE-OPERATING TEST PROCEDURE:

1. Before beginning this test, run the compressor system leak test and ensure it passes. There should be virtually no leaks in the tank circuit before performing this test.

2. Start tractor if not already running. Test results will be skewed if compressor supply voltage is inadequate (13.8 VDC no-load recommended).

3. Start a stopwatch when the Tank pressure reaches the 85 psi pressure valve.

4. Note the time to build 10psi in the tank.

5. If the time recorded is greater than 60 seconds, the compressor is either leaking or is considerably worn. Consider servicing or replacing the compressor before using. If no action is taken and the compressor continues to be used, closely monitor the 2940 Air Adjust system pressure availability.

That depends. The amount of Down/Lift Pressure will vary greatly across soil types, tillage practices, soil moisture, row unit weight and many other variables. Manage the pressure in the Down and/or Lift circuits in order to maintain 90%+ Ground Contact while keeping the pressure between 10-60 psi. The cab Controller will display on the screen, the Tank pressure in psi, and the Down/Lift circuits in psi. A typical starting range would be 32 up and 30 down. The 2940 controller allows for 5 saved settings. Press and hold preset to store setting desired. For no-till increase your down pressure settings and for conventional you will decrease your down pressure setting.

Normal operating ranges:

• Down Pressure Bags: 10-60 psi

• Lift Pressure Bags: 10-60 psi

Tank Pressure: 80 psi to 95 psi

The tank has a safety relief valve that will automatically exhaust excess pressure in the event that the pressure would exceed 150 psi.

1. Overview:

This electronic control system works with a pneumatic system that controls pressure in air-bags as well as other air valves in the system on an agricultural application. The air bags provide up and down pressure to mechanical devices that are used on an agricultural implement.

System Layout:

There are (2) main parts to the control system. The first being a VDM (Valve Drive Module), the role of the VDM is to provide Outputs to control functions of the pneumatic system, it will also provide Inputs to monitor the pneumatic system as well as provide feedback to the operator. The second part is an in-cab switch panel/display (Cab Controller) that allows the operator to control the pneumatic system and monitor its performance.

5. Main Screen System Operation

5.1. Supply +12Vdc to system. Before power button is pressed system will be in stand by mode, with red illuminated buttons.

5.2. Press and hold “Power” button, this will power up the switch panel.

5.3. The Air System needs to be enabled by pressing the ENTER button. This will allow the compressor to run. The compressor is controlled with a window switch that closes if it is below its threshold PSI, if pressure exceeds the threshold (approx 100 PSI) it will shut off until it falls below the bottom threshold of the window (approx 80 PSI) at that point it will close and attempt to run the compressor again. If the compressor runs for 15 minutes continuously it will shut off and the associated warning screen will be displayed; pressing ENTER will clear the warning screen and shut the air system off. Pressing ENTER again will restart the air system (the compressor will also restart if it needs to).

5.4. Pressure Adjustment: Along the bottom of screen 1 will be up to (6) pressures. These pressures are adjusted by using the rotary encoders. Adjusting these will put the system into edit mode and the values shown will be command values. After 7.5 seconds the system will exit the edit mode and the values will return to live values.

5.4. A Encoder 1: Adjusting this encoder will increment the RU (up pressure) command value up or down by 1 PSI/step.

5.4. B Encoder 2: Adjusting this encoder will increment the RD (down pressure) command value up or down by 1 PSI/step.

5.4. C Encoder 3: This encoder is used to adjust WT, A1, A2, and A3. You must press the encoder to enter the edit mode; a cursor will appear on the screen below the value you can adjust. It will start at WT and move right every time you press the encoder (if you stay in edit mode). Once the cursor is on the value you would like to adjust rotate the encoder and it will increment the command value up or down by 1PSI/step.

5.4. D Saving Presets: All PRESETS will default to 0 upon initial start up. Adjust one or more of the pressures to the desired value. Press any one of the P (1-5) buttons along the top of the switch panel for 2 seconds. This will save the values to that PRESET.

If you make an adjustment to a preset it will say PRESET x MANUAL at the top of the screen. Once you save the preset it will return to PRESET x.

5.5. RMU/RMD Dump Valve Operation: When dump valve button I is pressed the RM Down Dump will release air. When dump valve button I is pressed again RM Up Dump Output will release air for (x) seconds (this time delay is set in the DUMP VALVE DELAY screen). After the timer elapses both dump valves will be closed and the system will return to whatever pressure is being commanded by the PQE’s.

OPERATION PRECAUTIONS

STOP

Read this before using the Yetter product.

-MACHINE OPERATION

IMPORTANT: failure to properly set the planter frame height and levelness can result in less than successful operation of the planter and the Yetter product and may result in damaged equipment. All operators should read and thoroughly understand the instructions given prior to using the Yetter product.

NOTE: DO NOT use this product if the planter is not adjusted properly!

Leveling the planter: With the planter lowered to proper operation height (Usually 20”-22”). Read the planter operator’s manual for recommended setting. Check to be sure the toolbar and row unit parallel arms are level fore and aft. Re-Check when the planter is in the field and has been fully loaded with seed, fertilizer, granular chemicals, etc. Also, a field check with a bubble level on the frame should be made of the hitch height to ensure level operation front to back.

It is important for the planter to operate level laterally. Tire pressure must be maintained at pressures specified by the manufacturer.

Field and actual planting conditions change and will dictate planter frame heights. You must ensure that the row unit parallel arms are approximately parallel with the ground.

IMPORTANT: For proper operation of the planter attachments and row units, it is

imperative that the planter toolbars and row unit parallel arms be level side-to-side and front-to-rear. The toolbar frame should operate at a 20”-22” height from the planting surface. Check the manufacturer’s operator’s manual for instructions on how to adjust the frame height and levelness.

OPERATION PRECAUTIONS

OPERATION

Adjust the residue manager to move crop residue aside and not move any soil. Adjustments to the residue manager may have to be made when changing field conditions and type and amount of residue.

ROW CLEANER DO’S AND DON’TS

1. DO NOT move soil; Residue Managers are designed to move crop residue only.

2. DO NOT operate planter at slow speeds, ground speed affects how aggressive the spoke wheels are; operate at sufficient speed (4-6 mph) to maintain good residue flow.

3. DO NOT expect 100% of crop residue to be cleared, it is not necessary and would necessitate engaging the soil. The width of path cleared depends on ground conditions, depth setting and ground speed.

4. DO expect to see wheels occasionally quit turning, indicates ideal (shallow) setting which is not moving soil.

DO adjust toolbar frame height 20”-22” and drawbar correctly. Very important to ensure planter opener will follow ground contours properly. See Page 57 for the planter levelness and height.

IMPORTANT: For proper operation, the planter frame must operate level (fore, aft and side to side) and at the correct height, typically 20”-22”.
