The value for Driven or Drive Sprocket refers to the number of
teeth on the sprocket.
To calculate Ratio for a single stage chain drive, use the
following equation:
(Driven Sprocket ÷ Drive Sprocket)
EXAMPLE: 32 ÷ 16 = 2.000
This means the Drive Sprocket will need to make 2 complete
revolutions in order for the Driven Sprocket to make 1
revolution.
To calculate Ratio for a two stage chain drive, use the following
equation:
(First Stage Driven Sprocket ÷ First Stage Drive Sprocket) x
(Second Stage Driven Sprocket ÷ Second Stage Drive Sprocket)
EXAMPLE: (32÷ 16) x (28 ÷ 16) = 3.500
In the above example, the First Stage Drive Sprocket will need
to make 3.5 complete revolutions in order for the Second Stage
Driven Sprocket to make 1 revolution.
To calculate Ratio for a three stage chain drive; use the
following equation:
(First Stage Driven Sprocket ÷ First Stage Drive Sprocket) x
(Second Stage Driven Sprocket ÷ Second Stage Drive Sprocket) x
(Third Stage Driven Sprocket ÷ Third Stage Drive Sprocket)
EXAMPLE: (32 ÷ 16) x (28 ÷ 16) x (24 ÷ 18) = 4.666
In the above example, the First Stage Drive Sprocket will need
to make 4.666 complete revolutions in order for the Third Stage
Driven Sprocket to make 1 revolution.
Calculating your Flow Cal for a Planter Drive
1. Rows equals the number of rows the drive is running.
ROWS = ______
2. How many seeds are dispensed per revolution of your Seed
Meter Disc?
SMD = ______
3. What is the Ratio of hydraulic motor revolutions to seed
meter revolutions?
RATIO = ______ to 1
4. How many teeth are there on your Motor Sensor Sprocket?
MSS = _____
1000 Seeds ÷ ROWS = Seeds per Row
Seeds per Row ÷ SMD = Seed Meter Revolutions
Seed Meter Revolutions x RATIO = Motor Revolution
Motor Revolution x MSS = Pulses per 1000 Seeds (Flow Cal)
EXAMPLE:
ROWS = 12
SMD = 30
RATIO = 4.0
MSS = 16
1000 Seeds ÷ 12 = 83.333
83.333 ÷ 30 = 2.777
2.777 x Ratio = 11.111
11.111 x 16 = 177.8
177.8 = Flow Cal or Pulses per 1000 Seeds.

Installing the Planter Drive
1. Choose a location between row units for the tool bar mount
bracket approximately five inches to the left of a hex shaft
hanger bearing to the center of the tool bar mount bracket.
Mount the bracket to the tool bar using the supplied 1/2”
U-bolt making sure the bracket is square with the tool bar. It
is important to mount the drive assembly as close as possible
to a hex shaft hanger bearing.
2. Mount the motor bracket assembly to the tool bar bracket
using the four 3/8” by 1 1/4” flange bolts. Slide the motor
bracket towards the tool bar as far as it will go and tighten
the flange bolts.
NOTE: Skip step 3 if you are installing a secondary drive
assembly.
3. Mount the hydraulic flow control valve to the motor bracket
using the two 5/16” by 2 3/4” bolts and 5/16” flange nuts. Be
sure the output of the control valve is pointed away from the
tool bar.
4. Install the split sprocket on the hex shaft. Align the hex shaft
sprocket with the outside idler sprocket and tighten.
5. Cut a piece of chain to 23 1/2” and install on inside motor
sprocket and idler sprocket using one of the supplied
connector links. Tighten chain by loosening idler sprocket
and sliding down and retighten.
6. The length of chain required between the outside
idler sprocket and hex shaft sprocket varies by planter
manufacturer and model, so you will need to measure to
determine the length. Cut to length and install using the
supplied connector link.
.062”
7. Loosen the four 3/8” flange bolts installed in step 2.
8. Locate the full threaded 1/2” by 3” bolt, 1/2” jam nut and
1/2” flat washer. Install the flat washer on the bolt and insert
through the tab on the back of the tool bar bracket, thread
the jam nut on and then thread bolt into the motor bracket.
Use this bolt to adjust the chain between the idler and the
hex shaft and tighten the four 3/8” flange bolts.
9. Locate the four SAE #8 male x JIC #8 male straight adapters
and two 90 degree swivel nut elbows and install in both the
“P” pressure and “T” tank ports on the valve mounted on
top of the hydraulic motor. The other two adapters go in
the input and output ports on the control valve. Install the
elbows on the “P” port on valve and output port on control
valve.
10. Locate the 1/2” hose assembly and install between the “P”
port and output port.
11. Locate the SAE #8 male plug and install in the bypass port of
the control valve unless the drive assembly is connected to
an open center hydraulic system.
12. Install the sensor bracket to the motor bracket near the
motor sprocket using on of two 1/4” by 3/4” bolts and flange
nuts.13. Install gear tooth sensor to sensor bracket using the
remaining 1/4” by 3/4” bolt and flange nut and adjust so that
the sensor is pointed directly at the center of the motor shaft
and 1/16” away from the tip of the sprocket teeth.

Installing the Planter Drive (cont)
Determine your hydraulic system type before proceeding.
Is it an:
• Open Center System?
• Closed Center System?
• Pressure Compensating
• Closed Center Load Sensing?
From a hose connectivity standpoint, there are just TWO
VARIATIONS in plumbing and are referred to here as either Open
Center or Closed Center configurations.
NOTE: See the illustrations on the following pages for
hydraulic hose plumbing detail for opened and closed
center hydraulic systems as well as single, dual and multi-
drive configurations.
Calculate your Hydraulic Oil Needs
1. What is your Maximum Planting Speed in miles per hour?
MPS = _______
2. What is the closest Desired Seed Spacing in inches?
DSS = _______
3. How many seeds are dispensed per revolution of your Seed
Meter Disc?
SMD = _______
4. What is the Ratio of hydraulic motor revolutions to seed
meter revolutions?
Ratio = _______ to 1
5. What is the Displacement in Cubic Inches of the hydraulic
motor on your planter drive assembly?
CID = _______
EXAMPLE:
MPS = 5
DSS = 6.5
SMD = 30
Ratio = 5.333
CID = 4.9
• (MPS x 5280) x 12) = Inches traveled per hour
((5 x 5280) x 12 = 316800 inches traveled per hour
• Inches traveled per hour ÷ DSS = Seeds per hour
316800 ÷ 6.5 = 48738.46 seeds per hour
• Seeds per hour ÷ SMD = Seed meter revolutions per hour
48738.46 ÷ 30 = 1624.6 seed meter revolutions per hour
• Seed meter revolutions per hour ÷ 60 = Seed meter
revolutions per minute
1624.6 ÷ 60 = 27 seed meter revolutions per minute
• Seed meter revolutions per minute x Ratio = Hydraulic motor
revolutions per minute
27 x 5.333 = 144.4 hydraulic motor revolutions per minute
NOTE: the minimum recommended motor RPM is 30.
• Hydraulic motor revolutions per minute x CID = Cubic inches
of hydraulic oil per minute
144.4 x 4.9 = 707.6 cubic inches of hydraulic oil per minute
• Cubic inches of hydraulic oil per minute ÷ 231 = Gallons of
hydraulic oil per minute
707.6 ÷ 231 = 3 gallons of hydraulic oil per minute
Connecting the Planter Drive Assembly to the Hydraulic System
The hose end fitting required to mate with the supplied adapters
is a #8 JIC 37 degree female.
The recommended hydraulic hose size is 1/2” for both the
pressure and return hoses.
Be sure to route hoses away from pinch points and leave enough
excess length to accommodate folding and unfolding.
Whether you have an open or closed hydraulic system be sure
to turn the oil flow down to about 20% more than calculated
because the excess oil flow means excess heat.
See how to calculate your hydraulic oil needs at the top of this
page.
