Introduction 1

This manual describes how to set up and use the Trimble® ACCU-RATE®

controller.

Even if you have used other application controllers before, Trimble recommends that you spend some time reading this manual to learn about the special features of this product. If you are not familiar with GPS, visit the Trimble website (www.trimble.com) for an interactive look at Trimble and GPS.

About the ACCU-RATE controllerThe ACCU-RATE controller enables you to vary the rate at which seeds and fertilizer is applied. You can mount the ACCU-Rate controller to any planter, drill, air seeder, granular and air spreader or liquid applicator with constant volume pumps.

You can operate the controller itself to manually adjust the application rate, or you can automatically vary the rate by connecting the ACCU-RATE controller to one of the following:

• EZ-Guide® 500 lightbar guidance system

• AgGPS® FmX™ integrated display

You can program the controller to accurately control two different seed populations, or to simultaneously change seed at one rate and fertilizer at a different rate, when using two prescriptions. For more information, see Operation, page 21.

Calibration 2

In this chapter:

Calibrating the pressure gauge flow

Calibrating the flow control valve

Calibrating the controller

Determining RPM

This chapter describes how to calibrate the ACCU-RATE controller. To maintain maximum efficiency, you must calibrate the ACCU-RATE controller during installation as well as part of your regular maintenance schedule.


2 Calibration


Calibrating the pressure gauge flow

C CAUTION – Hydraulic oil under pressure can penetrate the skin and cause serious injury. You must relieve pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure. To avoid being sprayed by pressurized liquids, keep hands and body away from pin-holes which eject hydraulic oil under high pressure. Do not use your bare hands to check for hydraulic leaks. Use a board or cardboard instead.

Note – Do not operate the hydraulic drive without a pressure gauge.

To calibrate the pressure gauge flow:

1. Make sure the hydraulic drive is properly plumbed. For more information, refer to the ACCU-RATE Controller Installation Instructions.

2. Turn the hydraulic flow to minimum using the tractor remote that is driving the hydraulic drive.

3. With the hydraulic drives turned off, increase the hydraulic flow until the appropriate pressure (in pounds per square inch) is reached:

– Single drive = 800-1000 psi

– Dual drives plumbed in parallel = 1200-1500 psi

– Dual drives plumbed in series = 800-1000 psi

4. Test the amount of oil flow:

a. Press the MODE button once. The display should read Setup Product A.

b. If the display reads Setup Product B, press the SET button once until the indicator light for A is on.

c. Press the MODE button until the display reads Max. Speed 00.0 Off.


Calibration 2


d. Press the SET button until the display reads Max. Speed 00.0 On. This runs the hydraulic drive at the top of the RPM range.


5. If the unit does not run smoothly, adjust the oil flow by increasing the pressure on the gauge (see Step 3 through Step 4 above).

Calibrating the flow control valveUse a flow control valve when a controlled flow to one of the drives is needed. For example, if you use one drive for planting and one for fertilizer you will need a flow control valve.

Note – Oil flow from the tractor must be approximately 12 gallons per minute (GPM).

To calibrate the flow control valve:

1. Turn the lever on the flow control valve to position 10.

2. Use the tractor remote that is driving the hydraulic drive to:

a. Set the hydraulic flow to minimum.

b. Set the tractor flow pressure to 1100 PSI.

3. Turn down the lever on the flow control valve until the pressure gauge reads 1000 PSI.

4. Use the tractor remote to turn up the flow until the pressure gauge reads 1100 PSI.

5. Set the pressure with both “A” and “B” drives off.


2 Calibration


Calibrating the controllerNote – During operation, the controller must receive at least 12 volts DC at all times.

Calibrating the controller requires calculating the number of seeds that drop out of one hopper every time the hydraulic drive motor turns five revolutions. This determines the number of revolutions the motor must turn to plant the desired population.

The larger the calibration number, the slower the motor RPM.

To count the seeds that are dropped, you must run the planter in the Calibration Mode. If the calibration number entered is incorrect, the seed population is also incorrect.

To calibrate the controller:

1. For meters with finger pickup, seed plates or seed discs, note down the following information:

a. Number of teeth on the motor sprocket (usually 12).

b. Number of teeth on the first of the double reduction sprockets (usually 24).

c. Number of teeth on the second of the double reduction sprockets (usually 16).

d. Number of teeth on the driven sprocket of the drive shaft (usually 36).

e. Number of teeth on the drill shaft.

f. Number of teeth on the seed meter drive.

g. Number of cells or finger pickup.

2. Use the information you noted in step 1 to calculate the calibration number using the following formula:

3. Enter the calibration number on the controller.

After calibrating the controller, you must calibrate the ground speed.

5 ab--- c

d--- e

f-- g CalibrationNumber=××××


Calibration 2


Calibrating ground speed

1. To calibrate the ground speed, measure out a distance of 400 feet on a rough surface, such as gravel or in a field. Mark your start and end points.

Note – Ground speed is measured on the “A” side of the controller only. If you need to recalibrate, always make sure Cal. Feet = 400 is displayed.

2. Turn off the controller, and then turn the controller back on.

a. Press the SET button once. The display should readSPEED = 0.0 MPH.

b. Press the SET button until the display reads Counting Feet.

3. Approach your marked start point, traveling at normal speed.

4. As you pass the first start point, press the MODE button once

5. As you drive past the end point, press the SET button once.

The number displayed is the new calibration number.

6. Turn off the controller and then turn the controller back on.

7. Press the MODE button until the display reads Cal. Feet = 400.

8. Change the number 400 to the new number displayed in step 5:

a. Press the SET button to scroll between 0-9.

b. Press the MODE button to move the cursor to enter your new number.

c. Continue pressing the MODE button to save your presets.


2 Calibration


Determining RPMNote – It is important to check the hydraulic drive motor revolutions per minute (RPM) regularly. The drive will not function properly if the RPM is too fast or too slow. For smooth hydraulic motor operation, the hydraulic drive must run 100-300 RPM for planting and 100-500 RPM for fertilizer.

Revolutions per minute (RPM) calculation formulas are provided for the following modes:

• Planting mode

• Dry Fertilizer mode

• Liquid Fertilizer mode

Determining RPM for Planting mode

1. Note down the following information:

– Highest SDS/ACRE (seeds per acre)

– Lowest SDS/ACRE

– Row width

– MPH (planting speed in miles per hour)

– Number of seeds dispensed in 5 revolutions of the hydraulic drive

2. Use the information you noted down in step 1 to calculate the RPM using the following formulas:

Note – You must calculate the RPM for each row crop you are seeding.


Calibration 2

a. To determine the maximum RPM:

b. To determine the minimum RPM:

Note – If the RPM calculations do not meet the listed requirements, you

must change the sprocket ratios until the appropriate RPM is reached.

Determining Dry Fertilizing mode RPM


– Application rate

– Spread width

– Ratio


– Delivery rate

– Rate setting

– Material weight

2. Use the information you noted down in step 1 to calculate the RPM using the following formula:

Note – If the RPM calculations do not meet the listed requirements, you

must change the sprocket ratios until the appropriate RPM is reached.

2. Use the information you noted down in step 1 to calculate the RPM using the following formula:

Note – If the RPM calculations do not meet the listed requirements, you must change the sprocket ratios until the appropriate RPM is reached.

Maintaining Optimum RPM

To keep the RPM in the optimum range, you may need to use double reduction sprockets, as shown. This eliminates the need to use the transmission on the planter.

For piston pumps, use a flex coupler for a 1:1 ratio.

Operation 3

In this chapter:

Programming the controller

Operating the controller in the field

This chapter describes how to program and operate the ACCU-RATE controller.

You can program the ACCU-RATE controller to control variable rate drive applications for one or two hydraulic drives.


3 Operation


Programming the controllerThe ACCU-RATE controller is activated by one of the following modes of operation:

• GPS mode: GIS (Global Information System) and your mapped prescriptions are used to automatically actuate the ACCU-RATE controller and hydraulic drive(s).

• Non-GPS mode: use the 32-position rate control dial to manually actuate the ACCU-RATE controller and hydraulic drive(s).

The ACCU-RATE controller can operate two programs, one for each product:

• Product A: Planting mode

• Product B: Planting, Dry Fertilizing, or Liquid Fertilizing modes (can be used with air, granular spreaders or liquid applicators with constant volume pumps)

Each program is independent, so each can operate different applications at different percentage changes. This is true for both GPS and Non-GPS operating modes. However, if the controller is run in Non-GPS Mode, both drives activate since there is only one rate control dial.

Note – If you use a single hydraulic drive, you must disable Product B. If this is not done, a Motor Stalled error message for product B appears on the controller display.

Disabling product B

1. Press the Power button to turn on the ACCU-RATE controller.

2. Press the MODE button. The display reads Setup Product B.

Note – If the display reads Setup Product A press the SET button to switch to B.

3. Press the MODE button. The display reads Planting Mode.

4. Press the SET button until the display reads Disabled.

5. Press the MODE button twice.


Operation 3


Saving the program

1. If you make a mistake while programming the controller, press the MODE button to scroll through the Calibration Mode presets until you see the Save Presets YES message.

Note – If the display reads Save Presets NO instead, press the SET button once to change it to YES.

2. Press the MODE button to save all program calibrations to memory.

3. To resume programming, press the MODE button until you find the place where you left off.

B Tip – To reset the controller, turn off the controller and then turn it back on.

Programming functions

Many factors will determine exactly how you program the controller for your own use. The following sections provide notes and a flow chart to help you set up each type of program.

The table below describes each function that appears on the controller display.

Function Purpose

Planting Mode Program the controller (Product A or B) for seeding.

Dry Fert. Mode Program the controller (Product B) for dry fertilizer.

Liquid Fert. Mode Program the controller (Product B) for liquid fertilizer.

Disabled Disable a product. For example, you must disable Product B when using the controller only for seeding.

Non GPS Mode Change the application rates manually.

Fixed Rate Mode Lock the application rate at the setup rate (this disables the Rate control dial).

Fieldstar Mode If you use this function, contact your local Agco Fieldstar representative.

Maintenance and Testing 4

In this chapter:

Pre-season maintenance

Post-season maintenance

Gear inspection

Hydraulic test

Manual speed test

Ground speed sensor test

Removing plugs or covers from the hydraulic drive

This chapter describes how to maintain and test the ACCU-RATE controller.

Note – It is important to inspect and clean your ACCU-RATE system regularly so that the controller runs as accurately and efficiently as possible. At minimum, Trimble recommends you clean, test and inspect your system each year before your application season begins, allowing enough time to repair or replace any parts as necessary.


4 Maintenance and Testing


Pre-season maintenanceBefore the start of each season, Trimble recommends that you inspect the following parts of the system:

After inspecting each part of the system, test the applicator manually:


1. Turn on the ACCU-RATE controller.

2. Press the MODE button.

3. To set the drive output you want to run, press the Set button and then select A or B. The indicator light shows the drive you have selected.

Part Action

Hydraulic hose Replace any worn or cracked hose.

Cables Make sure all cables are plugged in.Replace any worn or damaged cables.

Drive chains Tighten any loose chains.

Sprockets Replace any worn sprockets.

Hydraulic drive To inspect it for leaks, remove the drain plug (see Removing plugs or covers from the hydraulic drive, page 43).To clean, insert a pipe cleaner into the drain to remove any plugs and allow the oil to drain. If this is done each year, no more than 1/4 cup of oil should drain.

Note – If more than 1/4 cup of oil drains, you may have a motor leak. Contact Trimble Support.

When complete, reinstall the plugs and covers.

Hydraulic filter Replace the removable element each year to keep the hydraulic drive clean and reduce dirt-related problems in the field.

Controller Check that it is programmed correctly.




4. Press the MODE button until the controller display reads Man Spd 00.0 Off.

5. To manually run the hydraulic drive:

a. Turn on the tractor hydraulics.

b. Press the SET button until the controller display reads Man Spd 00.0 ON.

6. To turn off the drives, press the SET button again.




Post-season maintenanceNote – The controller contains a liquid crystal that cannot withstand extreme temperatures. To avoid damage, store the controller above 0 °F (-18 °C).

After each season, Trimble recommends that you clean the drives and then move the controller indoors so that it does not freeze.




Gear inspection


1. Remove the inspection cover from the hydraulic drive (see Removing plugs or covers from the hydraulic drive, page 43).

2. Turn on the ACCU-RATE controller.

3. Press the MODE button until the display reads Man Spd 00.0 Off.

4. Keeping the hydraulics off, press the SET button. The gears will turn.

5. Look inside the inspection port. If the gears do not turn or do not turn smoothly:

a. Check the cables for damage or breaks. Replace cables if necessary.

b. Check the battery for 12 volts. Charge or replace battery if necessary.

6. Make sure that the idler arm is rotating.

7. Make sure that the unit shuts off.

If these steps do not work, contact Trimble Support.

8. When complete, reinstall the plugs and covers.




Hydraulic test


1. Start the tractor and turn on the hydraulics.

2. Turn off the ACCU-RATE controller and then turn on the controller.

3. Press the MODE button until the display reads Man Spd 00.0 Off. The indicator light turns red.

4. Press the SET button once. The indicator light turns green.

5. At this time, the hydraulic drive(s) should be turning. If it is not:

a. Move the tractor hydraulic lever to another position until the drive(s) turns.

b. Make sure the hose ends are correctly installed in the tractor. If they are not, follow the tractor manufacturer's instructions.

c. Inspect all chains and replace any that have slipped off the sprockets.

d. Make sure you have removed the ground chain from the seed transmission.

e. Make sure the unit is getting the required amount of oil (see Calibrating the pressure gauge flow, page 14 and Calibrating the flow control valve, page 15).

f. Make sure the RPM meets the requirements for your unit (see Determining RPM, page 18).

If these steps do not work, contact Trimble Support.




Manual speed testTest your seed meters, fertilizer, insecticide and dry herbicide under controlled conditions by simulating the ground speed.

Trimble recommends you run these tests twice. The first test is to make sure your seed discs are full; there is no need to check your results at this time. Use the results from the second test to check your planter.

Note – Do not turn off the tractor hydraulics during these two tests.

Use the table below to calculate the number of feet you normally run when checking the planter in the field. For seeding, it is recommended that you run 1/100 of an acre for corn and 1/400 of an acre for beans. Multiply your count by 100 for corn and 400 for beans.

To manually test your speed:

1. Enter your normal planting speed.

2. Run test feet:

a. The hydraulic drive runs off the numbers you entered in Step 1.

Note – The rate dial does not work at this time.

3. Adjust the calibration numbers as necessary until the desired population is reached.

Ground speed sensor test1. With the tractor turned off, turn on the ACCU-RATE controller.

2. Press the SET button. The display reads SPEED=0.0 MPH.

3. If you are using radar, you must simulate movement by the radar sensor. To do this, do one of the following:

– Place a fan in front of the sensor.

– Ask a second person to wave their hand in front of the sensor.

The MPH on the display changes with the movement.

4. If the MPH on the display does not change with the movement, contact the radar manufacturer for more information.




Removing plugs or covers from the hydraulic driveNote – Before removing any plugs or covers from the hydraulic drive, make sure you are in a clean environment.

1. Remove the hydraulic drive from the tractor, and relocate the drive to a clean environment.

2. Use a 1/8 inch Allen wrench to remove the drain plug, as shown.

3. Use a 1/8 inch Allen wrench to remove the inspection cover.
