This manual relies on information found only in your Operator’s Manual. Have both available when preparing to plant.
Setting Planting RateThere are four to six steps to obtaining the desired num-ber 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 43
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 59.
5. Set meter rate
Two sprocket sets are configured at each gauge wheel:
a. rangeb. transmission
See “Sprockets” on page 3.
6. Check planting rate
See “Checking Planting Rate” for each meter type.

Seed Lubricants
Singulator Plus Meters (all seeds)
Ezee Glide Plus Talc-Graphite Mix
821-069C bucket, 5 gallon (19 liter)
Ezee Glide Plus LubricantTo maximize performance of Great Plains metering sys-tems, it is imperative to use only “Ezee Glide Plus” lubri-cant. 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 sprinkleone 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 toone 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.
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 concentra-tions. As with all mineral spills, minimize dusting during clean-up. Prolonged inhalation may cause lung injury. Prod-uct can become slippery when wet.
Finger Pickup Meters
EZ-Slide Graphite Powder
821-042Cbottle, 1 pound (450 grams)821-060Cjug, 5 pound (2.3 kg)
For Finger Pick Up Meters OnlyUse 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 concentra-tions. As with all mineral spills, minimize dusting during clean-up. Prolonged inhalation may cause lung injury.

Sprockets
Sprockets control seed rate only for singulating, volu-metric and finger pick-up meters. Small seed (feeder cup) rate is independent of these sprockets.
Drive Speed Range SprocketsSelect 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 sprockets 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 14in slack in its longest span. Tighten idler and install retaining pins.
Set the same drive range sprocket combination on both gauge wheels.
Transmission SprocketsTo change the seeding rate, change the transmission sprocket combination. Refer to the Seed Rate Charts beginning on page 4. Note which sprocket is Driving and which is Driven .
Refer to Figure 2
Loosen idler plate and remove drive chain . Remove lynch pins from shafts and rearrange drive and driven sprockets as necessary.
Reroute drive chain over sprockets and idlers as shown. Move idlers into chain so chain has 14in slack in its lon-gest span. Tighten idlers and install lynch pins.
Set the same transmission 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.
The rates indicated in the charts are approximate values. To assure the most accurate seeding rate it is recom-mended 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.
Reading a Singulated Rate Chart
These charts are estimations of maximum seed rates for the Yield-Pro planter. Actual results will vary based on conditions and machine maintenance. Maintain your Yield-Pro Planter regularly for optimum performance.
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).
5. Note the maximum ground speed for that population.
6. The Range sprockets are at the top of the columns for the row spacing.
7. The Transmission sprockets are in the table rows, found to the left of the Population.

Checking Singulated Seeding RateThe 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 dis-tance.
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 mea-suring for 1200 acre or 1,000 if measuring for 11000 acre. This is the plant population in seeds per acre.
Example 1:If you have a 912in row spacing drill, according to the 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 Man-ual. • Refer to “Troubleshooting” in the operator’s manual.
Seed Rate ChartsSeed rate charts begin on the next page. The charts give transmission sprocket combination and drive range sprockets for row spacing used, to achieve the popula-tion desired. The charts also give seed spacing and max-imum planting speed.
Note: USE 1200 ACRE FOR POPULATIONS LESS THAN 100,000 SEEDS/ACRE. USE 11000 ACRE FOR POPULATIONS ABOVE 100,000 SEEDS/ACRE.

Volumetric Charts
Volumetric meter planting rate is determined by:
• crop and seed variant• meter wheel selection, and• meter drive configuration
The are no other adjustments.
The rates indicated in the charts are approximate values. To assure the most accurate seeding rate it is recom-mended that the drill be calibrated for the desired seed at the time of planting.
Reading a Volumetric Rate ChartHydraulic or Ground Drive1. 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.
6. The Range sprockets are at the top of the columns for the row spacing.
7. The Transmission sprockets are in the table rows, found to the left of the Seed Rate.

Checking Volumetric Seeding RateThe 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 revolu-tions 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:
• Double check transmission sprocket and drive range sprocket combinations. • Check for meter malfunction.• Check for correct seed meter wheel.• Check that all three rows are getting seed.• Refer to Troubleshooting in the operator’s manual.
9. Readjust transmission and/or range sprockets and repeat test.

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 opti-mum results:
1. Meter brush (see page 43)
2. Twin row indexing (see page 59)(For all seed corn types)
Great Plains always recommends test stand calibra-tion of the finger meter to the population and ground speed desired.
Recommended speed is 412 to 5 miles per hour.
Excess speeds are known to deteriorate seed spacing control and depth control.
Reading a Finger Meter Rate Chart1. 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 popula-tion.
The shaded rpms are the recommended rpms for most consistent results. Use the recommended driving speed if possible.
4. Each chart page shows the Range and Upper Drive sprockets at the upper left.
5. The Transmission sprockets are in the table, found to the left of the Population.

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 dis-tance.
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 mea-suring for 1200 acre or 1,000 if measuring for 11000 acre. This is the plant population in seeds per acre.
Example 1:If you have a 912in row spacing drill, according to the 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 Man-ual. • Refer to “Troubleshooting” in the operator’s manual.
Seed Rate ChartsSeed rate charts begin on the next page. The charts give transmission sprocket combination and drive range sprockets for row spacing used, to achieve the popula-tion. The charts also give seed spacing and maximum planting speed.
Note: USE 1200 ACRE FOR POPULATIONS LESS THAN 100,000 SEEDS/ACRE. USE 11000 ACRE FOR POPULA-TIONS ABOVE 100,000 SEEDS/ACRE.

Finger Meter AdjustmentsThe 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 AdjustmentThe 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 pick-up 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 screw-driver rather than lever. If so, rely on counting de-tents 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.
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 InsertsRefer 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 representa-tive for a recommendation.
The identification of the insert type is molded into the back of the insert.
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 abra-sive. Seeds with Maxi, Captan, Cruiser, Poncho and similar treatments can benefit from graphite. Use the amount recommended on the graphite container, usu-ally 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.
Always pay attention to your seed monitor and operat-ing manual. Monitor the amount of seed you are plant-ing 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 612 inches,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 612in,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 68.
Refer to Figure 51. 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 col-umn.
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 (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 AdjustmentIf, 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.
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 spac-ing being planted.
6-Finger Meter Stagger AdjustmentFind 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 col-umn of the seed indexing chart represents a small move-ment 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 popu-lation 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 num-ber 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 popu-lation 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 AdjustmentBefore making any Indexing Adjustments, check actual planted seed spacing. Seed Spacing is found by measur-ing 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 index-ing chart for actual seed spacing being planted.
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 col-umn of the seed indexing chart represents a small move-ment of the rear row seed relative to the front row seed.
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 pop-ulation 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 pop-ulation 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.
