Singulator Plus Meters (all seeds)

Ezee Glide Plus Talc-Graphite Mix

821-069C bucket, 5 gallon (19 liter

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.

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. Product can become slippery when wet.

Finger Pickup Meters

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.

Sprockets

3

Adjusting the seeding rate requires the following:

• adjusting drive speed range sprockets,

• adjusting transmission sprockets,

• preparing seed meters, and

• checking seeding rate.

Before setting the seeding rate, rotate the gauge
wheels. Check that seed meters, seed tubes and
drives are working properly and free from foreign
material.

Drive Speed Range Sprockets

Select the correct drive speed range sprockets for
your seed by referring to Seed Rate Charts, be­ginning on 6.

Refer to Figure 1

Loosen idler plate (1) and remove chain. Remove
retaining pins from shafts and install speed range
sprockets as necessary.

NOTE: Make sure the correct sprockets have
been installed in the DRIVER and DRIVEN loca­tions as shown.

Reroute chain over sprockets and idlers as
shown. Move idler into chain so chain has 1/4­inch to 1/2-inch slack in its longest span. Tighten
idler and install retaining pins.

Transmission Sprockets

To change the seeding rate, change the transmis­sion sprocket combination. Refer to Seed Rate
Charts, beginning on 6.

Refer to Figure 2

Loosen idler (1) and remove drive chain. Remove
lynch pins from shafts and rearrange driver and
driven sprockets as necessary.

Reroute drive chain over sprockets and idlers as
shown. Move idlers into chain so chain has #-inch
slack in its longest span. Tighten idlers and install
lynch pins.

Set the same transmission sprocket combination
on both sides of drill.

Checking Seeding Rate

Checking Volumetric Seeding Rate

The seed charts are based on cleaned seed and

12.5 x 15, rib implement transport tires and 13 x

5.00 - 6 contact drive wheel 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.

Refer to Figure 3

Great Plains Mfg., Inc.

3. Turn contact drive wheel clockwise a few
turns to fill meters with seed and until seed
drops to ground from all three openers.

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

5. Turn contact drive wheel clockwise 420 revo­lutions. Check to make sure seed tubes have
plenty of seed covering them.

6. 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 drill openers for the pounds­per-acre seeding rate.

7. 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 the troubleshooting guide in the

operator’s manual.

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, 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. Count the number of seeds, in the appropriate num­ber of rows, over the distance measured.

6. Multiply the number of seeds counted by 200 if
measuring for 1/200 acre or by 1,000 if measuring
for 1/1,000 acre. This is the plant population in
seeds per acre.

Example 1:

If you have a 10" row spacing drill, three rows must be
counted. Measure 17’ 5” 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 30" row spacing drill two rows
must be counted. Measure 87’ 1” and count the number
of seeds in two rows. If the number is, for example, 170,
multiply 170 by 200.

170 x 200 = 34,000 seeds per acre.

7. If the planting population issignificantly 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 the troubleshooting guide in the operator’s
manual.

Seed Rate Charts

Seed rate charts begin on page 6. The charts give trans­mission sprocket combinations and drive range sprocket
combinations used to achieve desired population or
pounds per acre for each row spacing. The charts also
give seed spacing for singulated and volumetric seeds.
