Stationary Method for Meter Verification

IMPORTANT: Avoid errors. Configure all cart, tool, and tractor configurations first for accurate results. All tank meters and the speed sensor on cart tire must be calibrated. (Refer to Performance Monitor and Monitor Setup sections to complete all these requirements first.)

1. Select a target application rate.

2. Properly configure meter segments.

3. Fill tank with enough product to collect a sample and maintain coverage over meter inlets. Do not pile product on one side of tank.

4. Place half-width disconnect handles fully down.

5. (Stationary Double-Shoot System Only) Move slide to bottom shoot position.

6. Verify that meter is full. If not, run a meter calibration, seed a short distance, or turn on the meter with toggle switch.

7. Shut off hydraulics and place tractor transmission in park.

8. NOTE: To verify more than one meter at a time accurately, a separate scale must be used for each meter. Collection bags weigh different amounts and have a different zero reference on scale.

   A - Collection Bag

   B - Scale

   Hang empty collection bag (A) from scale (B). Turn scale on and push zero button. If more than one bag and scale are used, label bags and scales as matched sets.

10. IMPORTANT: Do not operate fan with collection bags installed.

    Install collection bag.

11. Set application rate for the meter being evaluated.

13. Select Meter Verification drop-down.

14. Check box for the tanks being calibrated at this time (A).

15. Check box for Stationary Calibrate (E).

16. NOTE: Area to simulate input field ranges from minimum of 0.1 to maximum of 2.0.

    Enter area to simulate (F) in input box. For products with high application rates enter a lower number. For products with low application rates enter a higher number.

17. IMPORTANT: Avoid damage. Slide must be in bottom-shoot position on machines with stationary double shoot manifolds.

    NOTE: Check product level occasionally. Do not overfill collection bag.

    A - Collection Bag

    B - Scale

    C - Area to Simulate

    Remove the collection bag (A), hang it from scale (B), and record weight.

19. Calculate application rate as follows:

    Sample Weight kg (lb.) ÷ Area to Simulate ha (acre) (C) = Application Rate kg/ha (lb./acre)

20. If actual rate equals target rate, return half-width disconnect handles and double shoot slide to original positions.

    If actual rate does not equal target application rate, perform the following:

    NOTE: See your John Deere dealer for assistance, if needed.

    • Verify that tanks did not run out of product over any meter inlet.
    • Verify meter components and meter setup on monitor are properly configured.
    • Calibrate cart tire sensor. (See CONFIGURE TIRE SPEED SENSOR in Monitor Setup section.)
    • Calibrate meter. (See METER CALIBRATION in this section.)
    • Verify proper monitor setup.
    • Verify proper tire pressure.
    • Empty the collection bag and perform rate verification again.
