3-Point Precision Seeding System

Marker Option

Used with:

• 1510P and 1520P

• 2010P and 2020P

General Information

When you see this symbol, the subsequent instructions and
warnings are serious - follow without exception. Your life and

!

!

the lives of others depend on it!

These instructions explain how to install the Mark­er Option on the 15 and 20 foot 3-point Precision
Seeding Systems.

The markers fold and unfold hydraulically for field
operation. The marker disks leave a line for the
drill operator to follow on the next field pass. Mark­ers are mounted on the drill frame and require two
hydraulic remote valves on the tractor. A se­quence valve is available so markers can be
operated on one hydraulic circuit.

These instructions apply to:

Before You Start

Page 7 is a detailed listing of parts included in the
Marker Option package. Use this list to inventory
parts received.

15 foot A = 7 3/8 inches

20 foot A - 6 1/2 inches

1. Lower drill into field position. Allow 9 feet on
each end of a 15-foot drill and 11 feet on each
end of a 20-foot drill for marker assembly.

2. Mount first marker section (1) on drill 7 x 5
inch frame tube (2). Mount marker at the end of
the drill using dimension "A" as a starting point.
Some row spacings will require the mount to
be adjusted in or out from this starting point.

3. Secure marker section with 5/8 inch u-bolts
(3), lock washers, washers and nuts (4). and
1/2 inch u-bolts (5), lock washers and nuts (6).

NOTE: On the 20-foot drill with 15 inch row spac­ing, the last opener is bolted to the marker mount
using 5/8 x 6 1/2 inch straight bolts (7).

4. Remove port plugs on cylinder and carefully
unfold first marker section. Rotate hinge sec­tion (7) into a horizontal position.

5. Align holes of break-away section (8) with
holes in hinge section. Bolt sections together
using a 5/8-inch pivot bolt (9), lock nut (10), 3/
8-by-1 3/4-inch, grade 2 shear bolt (11) and
lock nut (12).

IMPORTANT: Be sure shear bolt is a grade 2
bolt. Failure to use a grade 2 bolt can cause
marker damage.

6. Repeat steps for other marker.

7. To adjust markers, refer to Marker Adjust-
ments in the operator’s manual.

Carrier Assembly for 20P drill

To assemble carrier onto drill frame, refer to Fig­ure 3

.

1. Assemble transport-carrier mount (1) on drill

frame. Center mount 49 inches from outside
end of drill frame. Use 1/2 x 6 1/32 x 7-inch
u-bolts (2), flat washers, lock washers and
hex nuts (3). Slide mount forward so its lead­ing edge is about 2 1/4 inches ahead of front
edge of drill frame tube.

2. Bolt transport carrier (4) to transport-carrier

mount so top surface of saddle (5) is about
29 1/4 inches above top of drill frame tube.
Secure transport carrier with 1/2 x 2 x 3-inch
u-bolts (6), lock washers and hex nuts (7).

3. After installing and bleeding hydraulics, trans-

port carrier may require further adjustment.
When folded, the second marker section
should rest in the transport-carrier saddle.

Installing Marker Hydraulics

Without Sequence Valve

Refer to Figure 4.

1. Install elbow fittings (1) in cylinder ports.

2. At rod end of each cylinder, install an adaptor

(2) into elbow fitting. Install a needle valve (3)
in adaptor.

3. Connect hydraulic hoses to fittings and route
hydraulic hoses to tractor outlets. Route hy­draulic hoses through transport-carrier mount
at cutout. Use black cable ties to secure hy­draulic hoses to drill frame.

4. Using orange cable ties, secure a plastic hose
label

, see Figure 5, to each pair of hydraulic

hoses near tractor outlets.

5. Proceed with "Bleeding Marker Hydraulics"
on page 6.

With Sequence Valve

Refer to Figure 6

.

1. Mount sequence valve (1) on drill using

mounting plate (2). Bolt plate to inside end of
left-hand-box panel (3) using one 1/2-inch
hex bolt (4).

2. Bolt valve to mounting plate with two 3/8 x

3/4-inch hex bolts and lock washers (5).

3. Install elbow fittings in cylinder ports. Discard

adaptor fitting and two needle valves provided
in marker kit.

4. Use hoses provided to connect valve ports to

cylinders. Refer to

Figure 7

for port connec-

tions.

5. Connect your own hydraulic hoses to ports on

front of valve. Route hoses to tractor outlets.

Bleeding Marker Hydraulics

You may be injured if hit by a folding or unfolding
marker. Markers may fall quickly and unexpectedly if
the hydraulics fail. Never allow anyone near the drill
when folding or unfolding the markers.

Escaping fluid under pressure can have sufficient pres­sure to penetrate the skin. Check all hydraulic lines
and fittings before applying pressure. Fluid escaping
from a very small hole can be almost invisible. Use pa­per or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.

!

CAUTION!

!

WARNING!

Great Plains Mfg., Inc.

1. Check that tractor hydraulic reservoir is full.

2. With both markers lowered into field position,
loosen hydraulic-hose fittings at rod and base
ends of marker cylinders. If applicable, loosen
fittings on back side of sequence valve.

IMPORTANT: Never bleed an O-ring fitting. In­stead, bleed a nearby pipe or JIC fitting.

3. With tractor idling, activate tractor hydraulic
valve until oil seeps out around a loosened fit­ting. Tighten that fitting.

IMPORTANT: JIC fittings do not require high
torque. JIC and O-ring fittings do not require
sealant. Always use liquid pipe sealant when
adding or replacing pipe-thread fittings. To
avoid cracking hydraulic fittings from over
tightening, do not use plastic sealant tape.

4. Reactivate tractor hydraulic valve until oil
seeps out around another loosened fitting.
Tighten that fitting. Repeat process until all
loosened fitting have been bled and tight­ened.

5. Adjust marker folding to a safe speed. Refer
to "Marker Adjustments" in the operator’s
manual.
