Singulated Planting Overview

The information in this section covers important setup and checking information that applies to both:

Singulator Plus (wheel, at left in Figure 2) meters and Finger Pickup meters (at right in Figure 2).

There are additional Sections for each meter. See also:

“Finger Meter Planting” on page 14 and “Singulator Plus™ Meter Planting” on page 7.

Singulating planting employs the seed monitor in “PLANTER CONTROL” mode. Volumetric planting uses “GRAN SEED CONTROL” or “granular” mode, and is covered at “Volumetric Meter Planting” on page 24.

Population Risk:

If the seed monitor is presently in GRAN SEED mode, follow the setup instructions carefully. Switching between seeding modes can cause some planter conﬁguration values to be reset to defaults that are incorrect for your planter.

Singulating Seed Meters

Population Reference Information

Seeds per Unit

If only pounds/acre (kilograms/hectare) is known, obtain the population count by multiplying the population weight by the “Kernels per pound” value from the seed container.

Example: Milo

Target rate: 4.5 pounds/acre Seed density: 14500 seeds/pound Population: = Rate x Density

= 4.5 x 14500, or: 65250 seeds/acre

Seed Spacing

If only seed spacing is known, use the tables on pages 5, 6 and 54 to determine population.

1. For your crop, determine your intended population, in seeds/acre or seeds/hectare. If you know only the population, the charts on page 5 and 54 correlate population to seed spacing for several row spacings.

2. For your crop, population and desired ﬁeld speed, verify the suitability and setup of your meter type, and seed wheel part number or ﬁnger count.

DICKEY-john Planter Operator Manual

Refer to the DICKEY-john

Quick Start Guide

IntelliAg® Planter/Drill

Control Operator’s Manual for details on setup item.

3. Verify, and as necessary setup or update the “Material” record for the singulated seed to be planted.

The table at right lists the parameters that need to be reviewed or set. Values in <angle brackets> are at your choice or preference.

4. Verify, and as necessary setup or update the “Channel” assigned to the planter’s hydraulic drive.

If the monitor resets to defaults, Gear Ratio may be incorrect.

Count rows individually for “# Seed Rows”. A twin pair (if both openers are in use) counts as 2 rows.

“Channel Width” is swath (number of active rows times spacing between active rows), for example:

465 in = 31 rows x 15in per row.

For twin rows, count twin pairs and pair-to-pair spacing, for example:

480 in = 16 twin pairs (32 rows) x 30 in pair spacing

5. In the Material Library screen, makes sure that the Material (SOYBEANS in our example) is assigned to the Channel (Ch 1 in our example) which controls the planter’s hydraulic drive.

6. Perform a Valve Calibration for the control channel.

7. Switch the seed monitor from Setup/Conﬁguration mode to Operate mode. Load seed. Move the planter to the ﬁeld.

8. Verify your planting rate per the instructions in the next topic. If the results are consistent with your setup, plant the crop.

Checking Planting Rate

Although your seed monitor will report useful full pass results, cautious practice includes manually checking the seed rate early in the ﬁrst pass.

The seed charts are based on cleaned and sized seed. Extreme seed variations, foreign material and tire pressure can materially affect planting rate.

Checking the rate also provides a double-check on your population calculations and drive conﬁguration.

The procedure is different for singulated seeding (this page) and volumetric seeding (page 26).

Seed Rate Check Sample Size

(U.S. customary units. See page 53 for metric.)

Checking Singulated Rate

1. Using the table above, determine the length and number of rows to check. For twin-row operation, a pair of row units counts as one row.

2. Adjust the planting depth to shallow on that number of rows units. Using center and wing-end row units for measurement provides a more accurate assessment of overall planter performance. Pick center units outside wheel tracks.

3. Use bungees or wire to tie-up the press wheel assembly on the tested row units, so that the seed is not covered. Tie up both in a pair for twin-row.

4. Operate the planter for the distance in the table, plus a few feet or meters for the press wheels to clear the end of the sample distance.

5. Count the number of seeds in the test rows.

6. Multiply the total number of seeds counted by 200 if measuring for1⁄

⁄

acre. This is the plant population in seeds per

1000

acre.

7. If the populated is substantially different than expected, see “Troubleshooting” in the planter Operator Manual.

Singulator Plus™ Meter Planting

Follow the steps in “Singulated Planting Overview” on page 2. At step 2 on page 2, follow the instructions in this section, which are speciﬁc to Singulator Plus™ meters when used with singulating seed wheels.

Volumetric planting with Singulator Plus™ meters is covered beginning on page 24. Singulated planting with ﬁnger pickup meters is covered beginning on page 14.

Maximum recommended speed is 7 miles per hour (11.3 kph), based on maximum meter rpms.

Excess speeds are known to deteriorate seed spacing control and depth control.

For your crop, verify that you have the correct seed wheels, and that your population and proposed ﬁeld speed are within limits for that wheel. See “Reading a Singulated Rate Chart” below.

When ordering seed wheels, note that there are different part numbers for: 10HD/25P Series ( wheels) and 20P Series ( wheels).

Reading a Singulated Rate Chart

• Consult the chart for your crop, meter wheel, cell count, and row spacing. Some crops have multiple seed wheels and pages.

• Find the table section for your row spacing.

• For your proposed ground speed, make sure your population or seed spacing is within range.

• Note minimum and maximum meter wheel rpms for that population.

• Enter the population and wheel cell count in the seed monitor.

Finger Meter Planting

Follow the steps in “Singulated Planting Overview” on page 2. At step 2 on page 2, follow the instructions in this section, which are speciﬁc to ﬁnger pickup meters.

Recommended maximum speed is 6 miles per hour (11.2 kph), based on meter rpm limits.

Excess speeds are known to deteriorate seed spacing control and depth control.

a. For your proposed ground speed, check that your

proposed population is within rpm limits for your 6- or 12-ﬁnger meters (this section, pages 15 and 77).

b. Set your meter brushes for your material (page 17).

c. If planting twin row, and indexing is desired, set the

stagger between the rows of each pair (page 19).

If you are planting indexed twin row, at “Singulated Planting Overview” step 8 on page 3, also check the row-to-row seed spacing in each row pair. As necessary:

d. Adjust the stagger between pair rows using the

instructions beginning on page 22.

Finger Meter Brush Adjustment

The ﬁnger pick up meter has an adjustable brush.

The brush reduces or eliminates “doubles” (delivering two seeds per ﬁnger), but if set too aggressively can cause “skips” (delivering no seed on some ﬁngers). As needed, adjust for minimal doubles and skips.

Refer to Figure 6

The adjustable brush provides additional ﬂexibility to accommodate a wide range of seed sizes. Use lever

to gently rotate the brush into position.

The settings range from 1 to 5 with detents at each half step, for a total of 9 detents. The factory default setting is 21⁄2. Although the numbers are molded into the meter housing, only “1” and “5” may be visible. To ensure consistency, rotate the lever fully counter-clockwise

(1), and count detents as you advance it to the desired setting.

Use the general guidelines in the table at right to adjust the brush position to your seed size and shape. The numbers listed correspond to the numbers printed on the outer housing of your meter.

If there is a decal on your meter, its units are in pounds per 80,000 seed bag. The table below includes seeds per pound.

Figure 6

Finger Meter Brush Lever

Note: These instructions describe the current ﬁnger

pickup meter shipped with new Great Plains planters, which has an integrated adjustment lever for the brush. If you have added pre-existing ﬁnger meters after purchase, there is some chance that you may have previous model meters, adjusted by screwdriver rather than lever. If so, rely on counting detents to determine the setting. Not all have 9 detents.

Finger Meter Inserts

Refer to Figure 7

The backing plate is equipped with an “A” insert . In tests, this insert provides the best performance in most seed sizes. However, there are two alternative inserts that can be used. Before changing to a different insert, please consult with a Great Plains service representative for a recommendation.

The identiﬁcation of the insert type is molded into the back of the insert.

Meter Performance Risk:

Be cautious in using seed treatments, additives, and other chemicals when possible. They can cause meter performance problems and premature wear to meter parts.

Avoid the use of graphite with untreated seeds. If graphite must be used, use Precision®Planting graphite or Great Plains graphite which is less abrasive. Seeds with Maxi, Captan, Cruiser, Poncho and similar treatments can beneﬁt from graphite. Use the amount recommended on the graphite container, usually 1 tsp(5ml)/unit or 1 tsp/80,000 seeds.

Figure 7

Always store meters in a dry, secure place, with brush in between two meter ﬁngers. Moisture, temperature, nest-building insects and rodents can create problems.

Always pay attention to your seed monitor and operating manual. Monitor the amount of seed you are planting compared to your expectations. Always investigate abnormalities!

Finger Meter Sprocket Indexing (Stagger)

This topic applies only to ﬁnger meters.

28420

If you are planting:

• ﬁnger-metered,

• twin-row crops,

• at seed interval spacings above 61⁄2 inches (16.5 cm), you can synchronize each pair of adjacent meters in a twin row so that you achieve the maximum seed-to-seed spacing between the units of the pair.

If you are planting:

- single-row,

- or with singulating meters,

- or a volumetric crop,

- or twin row with seed spacings below 61⁄2in (16.5 cm), this section of the manual, and the sprocket indexing charts, do not apply to your operations.

Figure 8

Sprocket Indexing

If the initial indexing does not provide equal spacing, see “Indexing Fine Adjustment” on page 22.

Refer to Figure 8

1. Find the chart for your row spacing, meter ﬁnger count and desired seed population. Note the “Tooth Number” value for the “Rear Meter” in the far right column.

2. Remove both meters of a row unit pair. Note that tooth 1 and many of the other teeth on the driven

sprockets , are stamped with a tooth number.

On front row unit:

3. Relax idlers on front meter drive by lifting the spring off the rear post .

4. Lift chain off driven sprocket , and rotate sprocket so that tooth 1 is as close as possible to straight up (TDC: top dead center, 12:00 position).

5. Re-engage chain and idlers, making sure chain is taut at top, and that sprocket tooth 1 has not shifted off TDC.

1 2

On rear row unit:

6. Relax idlers on rear meter drive by lifting the spring off the rear post .

7. Lift chain off driven sprocket , and rotate sprocket so that the tooth number called for in the chart is at TDC (or is the same as the front row sprocket).

8. Re-engage chain and idlers, making sure chain is taut at top, and that the designated sprocket tooth has not shifted off TDC.

9. Re-install meters. No particular wheel orientation is required during meter installation. The meter engagement is symmetrical, and the results identical no matter how the coupler captures the meter shaft.

Sprocket Indexing Charts

1. For: your 6- or 12-ﬁnger meter, and your twin row spacing (30in on this page) ﬁnd your seed rate in the Population column, or your seed spacing in the Seed Spacing column. Seed spacing is seed-to-seed within a single row of a twin row pair.

2. At the front/forward row unit of a pair, set the driven (ﬁnal) sprocket of the meter drive so that tooth stamped #1 is straight up (TDC, 12:00 position).

3. At the rear/trailing row unit of the pair, set the driven sprocket so that the tooth number at “Rear Meter” is in the straight up 12:00 position.

These charts are in U.S. customary units. See page 78 for metric charts (70cm twin row).

Indexing Fine Adjustment

If, after indexing, the twin-row side-to-side seed stagger is substantially imbalanced, it is possible to make small adjustments that may correct it. Imbalance can occur over time as row unit chains wear and stretch.

The procedure is different for 6- and 12-ﬁnger meters.

If an adjustment is made, test it on one row pair before adjusting the entire planter.

Before making any Indexing Adjustments:

• Check actual planted seed spacing. Seed Spacing is

found by measuring the distance between 25 correctly planted seeds in one row and dividing by 24. (A visible skip or double is counted as one seed.)

• Make sure the current front sprocket index is 1, and

the current rear sprocket index number matches the number in the indexing chart for actual seed spacing being planted.

6-Finger Meter Stagger Adjustment

Find your current indexing value row in the chart on page 20.

Each (sprocket tooth) number directly above or below the current rear meter sprocket setting in the right most column of the seed indexing chart represents a small movement of the rear row seed relative to the front row seed.

Changing rear your sprocket to the next number up in the chart retards, moving each rear row seed back a small amount.

Changing rear sprocket to the next number down in the chart advances, moving each rear row seed ahead a small amount.

Example 1:

The 6 Finger, Twin Row 30in planting population is 32000 or 13.1in seed spacing. The chart setting for the rear sprocket is [ 15 ]. Each rear row seed should fall

6.6in behind the front row seed.

If each rear row seed measures only 5in behind the front row seed, reset the rear meter sprocket to the next number up in the chart [ 12 ]. This moves the rear seeds back to make the stagger closer to 6.6in.

Example 2:

The 6 Finger, Twin Row 30in planting population is 32000 or 13.1in seed spacing. The chart setting for the rear sprocket is [ 15 ]. Each rear row seed should fall

6.6in behind front row seed.

If each rear row seed measures 9in behind the front row seed, reset the rear meter sprocket to the next number down in the chart [ 18 ]. This moves the rear seeds ahead to make the stagger closer to 6.6in.

Finger Meter Twin Row Sprocket Indexing

12-Finger Meter Stagger Adjustment

Before making any Indexing Adjustments, check actual planted seed spacing. Seed Spacing is found by

measuring the distance between 25 correctly planted seeds in one row and dividing by 24. (A visible skip or double should be counted as one seed.) Make sure current front index is 1, and current rear sprocket index number matches the number in the indexing chart for actual seed spacing being planted.

Find your current indexing value row in the chart on page 20.

Changing rear your sprocket to the next number down in the chart retards, moving each rear row seed back a small amount.

Changing rear sprocket to the next number up in the chart advances, moving each rear row seed ahead a small amount.

Example 1:

The 12 Finger Twin Row 30in planting population is 37000 or 11.3n seed spacing. The chart setting for the rear sprocket is [ 3 ]. Each rear row seed should fall 5.6in behind the front row seed.

If each rear row seed measures 7in behind the front row seed, reset the rear meter sprocket to the next number down in the chart [ 14 ]. This will move the rear seeds ahead and make the stagger closer to 5.6in.

Example 2:

The 12 Finger Twin Row 30in planting population is 37000 or 11.3in seed spacing. The chart setting for the rear sprocket is [ 3 ]. Each rear row seed should fall 5.6in behind the front row seed.

If each rear row seed measures 4in behind the front row seed, reset the rear meter sprocket to the next number up in the chart [ 11 ]. This will move the rear seeds back to make the stagger closer to 5.6in.
