General Information
These instructions explain how to install the optional markers.
The markers fold and unfold h ydraulically for field oper ation. The
marker disks leave a line f or 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 v alve is
available so markers can be oper ated on one hydraulic circuit.
These instructions apply to:

Manual Update
Refer to the drill operator’ s manual for detailed information on
safely operating, adjusting, troubleshooting and maintaining the
markers. Refer to the parts manual for part identification.

Assembly Instructions
Marker Assembly
Refer to Figure 1.
1. Lower drill into field position. Allow 15 feet of clearance from
each end of drill box for marker assembly.
2. Attach first marker section (1) to drill frame. Mount marker
as far out on drill frame as possible. Secure marker to drill
frame with 5/8-inch u-bolts (2), lock washers and he x nuts .
3. Remove port plugs from marker cylinder and carefully unfold first marker section. Rotate hinge (3) into a horizontal
position.
4. Assemble second marker section (4) onto first section so
that stop block (5) on second section faces up. Secure sec
tions with 5/8-inch bolt (6) and lock nut and 3/8-by-2-inch,
grade 2 shear bolt (7) and lock nut.
IMPORTANT: Use a grade 2 bolt for the shear bolt or marker
damage will occur during field operation.
5. Place third marker section (8) over end of second section
and insert hinge pin (9) through second- and third-section
pivot. Secure hinge pin with the 1/4-by-2-inch bolt (10) and
lock nut.
6. Bolt chain pivot (11) to first marker section with 3/8-by-3 1/4inch bolt (12) and lock nut so chain pivot piv ots freely on bolt.
7. Bolt chain bar (13) to third marker section
with the 3/8-by-1 1/2-inch bolt (14) and
lock nut so chain bar pivots freely on bolt.

8. Connect
marker
chain
(15) to
chain bar
and chain
pivot with utility
clevis (16). With
marker disk adjusted
for seeding width and
ground, remove chain slack with
utility clevis nearest drill.
9. Assemble full-threaded, 3/8-inch stop bolt
(17) and lock nuts on lift-arm extension (18) so
head of stop bolt extends as little as possible.
After the marker is bled and folded, adjust stop
bolt to remove slack from chain. Ref er to Mark
er Chain Adjustments, "Adjustments" in the
operator’s manual.

Assembly
Transport Carrier Assembly
Refer to Figure 2.
1. Assemble transport-carrier mount (1) on drill frame. Center
mount 50 3/8 inches from outside end of drill frame. Use
1/2-by-6 1/32-by-7-inch u-bolts (2), flat washers, loc k w ashers and hex nuts (3). Slide mount forw ard so its leading edge
is about 3 15/16 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 35 3/8 inches above top of drill
frame tube. Secure transport carrier with 1/2-by-2-by-3-inch
u-bolts (6), lock washers and hex nuts (7).

Assemble Needle Valves
3. Connect hydraulic hoses to fittings and route hydr aulic hoses to tractor outlets. Route hydraulic hoses through trans port-carrier mount at cutout. Use black cable ties to secure
hydraulic hoses to drill frame.
4. Using orange cable ties, secure a plastic hose holder to
each pair of hydraulic hoses near tractor outlets. See
4.
5. Proceed with "Bleeding Marker Hydraulics," page 3.
With Sequence Valve
Refer to Figure 5.
1. Mount sequence valve (1) on drill using mounting plate (2).
See Figure 5. Bolt plate to inside end of left-hand-bo x panel
(3) using one 1/2-inch hex bolt (4).
2. Bolt valve to mounting plate with two 3/8-b y-3/4-inch hex
bolts and lock washers (5).
3. Install elbow fittings in cylinder ports. Discard adaptor fitting
and two needle valves pro vided in marker kit.
4. Use hoses provided to connect valve ports to cylinders. Refer to Figure 5 for port connections.
5. Connect your own hydr aulic hoses to ports on front of valve.
Route hoses to tractor outlets.
6. Using orange cable tie, secure plastic hose label to h ydraulic hoses near tractor outlets. See Figure 4.

3. After installing and bleeding hydraulics, tr ansport carrier
may require further adjustment. When folded, the second
marker section should rest in the transport-carrier saddle
and be parallel with the drill box. Refer to Marker Adjust-
ments, "Adjustments" in the operator’ s manual.
Installing Marker Hydraulics
Without Sequence Valve
Refer to Figure 3.
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.
7. Proceed with "Bleeding Marker Hydraulics," page 3.

!
CAUTION!
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.
!
WARNING!
Escaping fluid under pressure can have suf ficient pr essure 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 tis
sue must be surgically remo ved within a few hours or gangrene will result.
1. Check that tractor hydraulic reservoir is full.
2. With both markers lowered into field position, loosen hy-
draulic-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 hydr aulic 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.
T o a void cr acking h ydraulic fittings from ov er tightening, do
not use plastic sealant tape.
4. Reactivate tractor hydraulic v alv e 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 Ad-
justment, "Adjustments," in the operator’ s manual.
