Seed Rate Application Charts for 2007+ 20ft and 25ft Precision Seeding Systems

The following pages are to assist in the proper setting of seeding and fertilizer application rates for the 20ft and 25ft precision seeding systems. The rates indicated in the charts are approximate values. To assure the most accurate seeding rate it is recommended that the drill be calibrated for the desired seed at the time of planting.

Note: These seed rate charts cover all drill models and series openers for the 20ft and 25ft precision drills.

If your drill is equipped with 25P series openers, singulating meters use a green wheel. If your drill is equipped with 20P series openers, singulating meters use a black wheel.

This manual relies on information found only in your Operator’s Manual. Have both available when preparing to plant.

Setting Planting Rate

There are four to six steps to obtaining the desired number of seeds per acre, some of which apply only certain meter types, and particular row unit conﬁgurations:

1. Know the characteristics of the seed

Consult your seed supplier’s reference documents.

2. Install the correct seed meters and wheels

Consult your Great Plains dealer and see “Seed Meter Setup and Adjustment” in the Operator’s Manual.

3. Adjust Finger Pickup meters for the seed

This only applies to ﬁnger pickup meters. See “Finger Meter Adjustments” on page 42

4. Sprocket index for staggered twin-row

On twin-row drills, with certain crops, get maximum beneﬁt with precise seed spacing between adjacent rows. See “Sprocket Indexing (Stagger)” on page 58.

5. Set meter rate

Two sprocket sets are conﬁgured at each gauge wheel:

a. range b. transmission

See “Sprockets” on page 3.

6. Check planting rate

See “Checking Planting Rate” for each meter type.

Ezee Glide Plus Lubricant

To maximize performance of Great Plains metering systems, it is imperative to use only “Ezee Glide Plus” lubricant. Ezee Glide Plus” Talc-Graphite lubricant is mandatory for all seeds, especially treated or inoculated seed. Thorough mixing of seed and added lubricant

is required.

Recommended usage:

For clean seeds other than milo and cotton sprinkle one cup of Ezee Glide Plus Talc per 4 bushels or units (170 ml per 100 liters) of seed.

For milo and cotton double the application to one cup (or more) per 2 bu or units (335 ml per 100 liters) of seed.

Adjust this rate as necessary so all seeds become coated while avoiding an accumulation of lubricant in the bottom of the hopper.

For seed with excessive treatment, or for humid planting environments, increase the rate as needed for smooth meter operation.

EZ-Slide Graphite Powder

821-042C bottle, 1 pound (450 grams) 821-060C jug, 5 pound (2.3 kg)

For Finger Pick Up Meters Only

Use only approved Graphite Powder available from Great Plains Mfg. Inc. or Precision Planting to ensure proper lubrication of ﬁnger pickup corn seed meters.

Recommended usage:

For ﬁnger pickup meters, add one tablespoon (15 ml) of graphite for each unit of seed corn (80,000 kernels).

In high humidity conditions, or seeds with heavy seed treatments, increase the application to two tbsp (30ml).

If delivery of seed from the hopper to the ﬁnger meter is an issue, add “Ezee Glide Plus” talc and graphite blend at a rate of one cup (237ml) per 4 units of seed. Adjust until issue is resolved.

Irritation and Chronic Exposure Hazard:

Wear gloves. DO NOT use hands or any part of your body to mix seed lubricant. Wear a respirator when transferring and mixing. Avoid breathing lubricant dust. Not an acute hazard. May cause mechanical eye or skin irritation in high concentrations. As with all mineral spills, minimize dusting during clean-up. Prolonged inhalation may cause lung injury. Prod-

Irritation and Chronic Exposure Hazard:

uct can become slippery when wet.

Sprockets

Sprockets control seed rate only for singulating, volumetric and ﬁnger pick-up meters. Small seed (feeder cup) rate is independent of these sprockets.

Drive Speed Range Sprockets

Select the correct drive speed range sprockets for your seed by referring to the Seed Rate Charts beginning on page 4.

Refer to Figure 1

Loosen idler and remove chain . Remove retaining pins from shafts and install speed range sprock-

ets as necessary.

Note: Make sure the correct sprockets have been in-

stalled in the DRIVER and DRIVEN locations as shown.

Reroute chain over sprockets and idlers as shown. Move idler into chain so chain has longest span. Tighten idler and install retaining pins.

Set the same drive range sprocket combination on both gauge wheels.

Singulating Meter Charts

Singulating meter planting rate is determined by:

• crop and seed variant

• meter wheel selection, and

• meter drive conﬁguration

There are no other adjustments.

Reading a Singulated Rate Chart

1. Consult the chart for your crop, meter wheel/cell count, and row spacing. Some charts have two pages.

2. Note whether talc only, or talc and graphite are required. See “Seed Lubricants” on page 2 for seed lubricant information.

3. Find the columns for your row spacing.

4. Find the desired seed population range (or seed spacing).

The rates indicated in the charts are approximate values. To assure the most accurate seeding rate it is recommended that the drill be calibrated for the desired seed at the time of planting.

Note: 20P series openers use a black seed wheels.

25P series openers use a green seed wheel.

Checking Singulated Seeding Rate

The seed charts are based on cleaned and sized seed. Extreme seed size variations, foreign material and tire pressure will affect the seeding rate. Check the seed population rate as described below.

1. Adjust the planting depth to a shallow setting.

2. Plant at the desired planting speed for a short distance.

3. Using the table below, determine how many rows need to be counted.

4. Measure a distance, according to the table, for the row spacing in the planted area.

5. Multiply the number of seeds counted by 200 if measuring for

⁄

acre. This is the plant population in seeds per

1000

acre.

Example 1:

If you have a 9 table, three rows must be counted. Measure 18ft 4in

and count the number of seeds in three rows. If the number is, for example, 180, multiply 180 by 1,000.

180 x 1,000 = 180,000 seeds per acre.

Example 2:

If you have a Twin Row 30in spacing drill, according to the chart, both rows of the twin row must be counted. Measure 87ft 1in and count the number of seeds in the parallel row. If the number is, for example, 170, multiply 170 by 200.

170 x 200 = 34,000 seeds per acre.

Note: Both rows of the Twin Row count as one row.

6. If planting population is signiﬁcantly different than desired, make the following checks:

• Double check the transmission and range

sprocket combinations. Refer to the seed population chart for the seed being planted.

• Check the air pressure in the gauge wheel tires.

Refer to “Tire Inﬂation Chart” in the Operator’s Manual.

• Refer to “Troubleshooting” in the operator’s

manual.

Volumetric Charts

Volumetric meter planting rate is determined by:

• crop and seed variant

• meter wheel selection, and

• meter drive conﬁguration

Reading a Volumetric Rate Chart

Hydraulic or Ground Drive

1. Consult the chart for your crop and meter wheel.

2. Note any seed lubricant required. See “Seed Lubri- cants” on page 2 for seed lubricant information.

3. Find the columns for your row spacing.

4. Find the desired seed rate (which is pounds per acre for volumetric seeds).

5. Note the maximum ground speed for that rate.

The are no other adjustments.

The rates indicated in the charts are approximate values. To assure the most accurate seeding rate it is recommended that the drill be calibrated for the desired seed at the time of planting.

Checking Volumetric Seeding Rate

The seed charts are based on cleaned seed and 11L x 15, rib implement tires. Factors including foreign material, seed treatment, seed size, seed weight, ﬁeld conditions and tire pressure will affect seeding rate. Set and check the seeding rate, then readjust the rate as necessary.

1. Record the weight of an empty container large enough to hold seed metered from three meters for one acre.

2. Place several pounds of seed over three seed meters on an outside end of the drill box.

Note: If drill box is full, shut off sliding seed tubes to all

but three meters on an outside end.

3. Raise drill off ground.

4. Turn gauge wheel a few turns to ﬁll meters with seed and until seed drops to ground from all three openers.

5. Place a container under the three openers to gather seed as it is metered.

6. Using the chart on the next page, select your row spacing and determine the correct number of revolutions per acre. Turn drive gauge wheel the selected revolutions for your row spacing. Check in box to make sure seed tubes have plenty of seed covering them.

7. Weigh measured seed. Subtract initial weight of empty container. Divide by three for the amount metered by each meter, then multiply by the number of rows for the pounds-per-acre seeding rate.

8. If seeding rate is different than desired:

Calibration Equations

• Double check transmission sprocket and drive

range sprocket combinations.

Finger Meter Charts

The basic seed rate for ﬁnger meters is determined by:

• meter drive conﬁguration, and

• the meter ﬁnger count (6 or 12).

Finger meters have two additional adjustments for optimum results:

1. Meter brush (see page 42)

2. Twin row indexing (see page 58)(For all seed corn types)

Reading a Finger Meter Rate Chart

1. Consult the chart for your row spacing and meter type.

2. Find the desired seed population or seed spacing.

3. Note the range of meter rpms suitable for that population.

IMPORTANT !

The shaded rpms are the recommended rpms for most consistent results. Use the recommended driving speed if possible.

IMPORTANT !

Great Plains always recommends test stand calibration of the ﬁnger meter to the population and ground speed desired.

IMPORTANT !

Recommended speed is 4

⁄

to 5 miles per hour.

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

Checking Finger Meter Rate

The seed charts are based on cleaned and sized seed. Extreme seed size variations, foreign material and tire pressure will affect the seeding rate. Check the seed population rate as described below.

1. Adjust the planting depth to a shallow setting.

2. Plant at the desired planting speed for a short distance.

3. Using the table below, determine how many rows need to be counted.

4. Measure a distance, according to the table, for the row spacing in the planted area.

5. Multiply the number of seeds counted by 200 if measuring for

⁄

acre. This is the plant population in seeds per

1000

acre.

Example 1:

If you have a 9 table, three rows must be counted. Measure 18ft 4in

and count the number of seeds in three rows. If the number is, for example, 180, multiply 180 by 1,000.

180 x 1,000 = 180,000 seeds per acre.

Note: USE

Example 2:

170 x 200 = 34,000 seeds per acre.

Note: Both rows of the Twin Row count as one row.

6. If planting population is signiﬁcantly different than desired, make the following checks:

• Double check the transmission and range

sprocket combinations. Refer to the seed population chart for the seed being planted.

• Check the air pressure in the gauge wheel tires.

Refer to “Tire Inﬂation Chart” in the Operator’s Manual.

• Refer to “Troubleshooting” in the operator’s

manual.

Finger Meter Adjustments

The ﬁnger pick up meter has an adjustable brush. The brush has been pre-set to the optimum setting for most seed sizes.

Finger Meter Brush Adjustment

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.

Note: These instructions describe the current ﬁnger

pickup meter shipped with new Great Plains drills, 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.

Refer to Figure 3

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

to gently rotate the brush into position.

Great Plains Mfg., Inc.

Finger Meter Brush Lever

Figure 3

25276

The settings range from 1 to 5 with detents at each half step, for a total of 9 detents. 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 below 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.

Finger Meter Inserts

Refer to Figure

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.

IMPORTANT !

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/unit or 1 tsp/80,000#.

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.

Figure 4

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!

Sprocket Indexing (Stagger)

This chapter applies only to ﬁnger meters.

If you are planting:

• ﬁnger-metered,

• twin-row crops,

• at seed interval spacings above 6 you can synchronize each pair of adjacent meters in a

twin row so that you achieve the maximum seed-toseed 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 6 this section of the manual, and the sprocket indexing

charts, do not apply to your operations.

If the initial indexing does not provide equal spacing, see “Indexing Fine Adjustment” on page 67.

Refer to Figure 5

1. Find the chart for your row spacing, meter ﬁnger count and desired seed population. Note the “Rear Meter Sprocket Tooth #” value 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.

1 2

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 (top dead center).

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

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.

Indexing Fine Adjustment

If, after indexing, twin-row side-to-side seed stagger is substantially imbalanced, it is possible to make small adjustments that may correct it.

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 drill.

6-Finger Meter Stagger Adjustment

Find your current indexing value row in the charts.

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.

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

28421

Example 1: The 6 Finger (Twin Row 30in) planting population is 29900 or 14in seed spacing. The chart setting for the rear sprocket is (15). Each rear row seed should fall 7in behind the front row seed.

If each rear row seed measures only 6in behind the front row seed, reset the rear meter sprocket to the next number up in the chart (12). This will move the rear seeds back to make the stagger closer to 7in.

Example 2: The 6 Finger (Twin Row 30in) planting population is 29900 or 14in seed spacing. The chart setting for the rear sprocket is (15). Each rear row seed should fall 7in behind front row seed.

If each rear row seed measures 8in behind the front row seed, reset the rear meter sprocket to the next number down in the chart (18). This will move the rear seeds ahead to make the stagger closer to 7in.

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

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 34800 or 12in seed spacing. The chart setting for the rear sprocket is (3). Each rear row seed should fall 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 up in the chart (11). This will move the rear seeds ahead and make the stagger closer to 6in.

Example 2: The 12 Finger (Twin Row 30in) planting population is 34800 or 12in seed spacing. The chart setting for the rear sprocket is (3). Each rear row seed should fall 6in behind the front row seed.

If each rear row seed measures 5in 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 back to make the stagger closer to 6in.
