Tri-Fold Marker Mounting &
Assembly Instructions
Remove contents of hardware box and sort parts
for identification. Refer to drawing lay-out. Using
the 3/4" x 7" x 11" U-bolts, 3/4" lock washers and
hex nuts, install mounting brackets to the 7 x 7
frame tube at the end of each wing frames.
Bolt marker base mount bracket ---right on the
right side of the drill, and left on the left side of
the drill--- using four (4) 1" x 3" HHCS and one
(1) 3/4" x 2 1/2" HHCS with flat washers, lock
washers, and hex nuts. To determine left and
right, stand behind drill looking to the tractor. To
your right is the right side of drill, and to your left,
the left side of drill.
Mount left marker base arm and right marker
base arm to marker base mount brackets using
base arm pivot pins (1 1/2" x 11") Refer to
drawing. Secure pins with 1/2" x 2 1/2" bolts and
hex nylock nuts. (Check part numbers to insure
correct side).
Attach the 3 x 20 hydraulic cylinder to the marker
base mounts using the pin provided with the
cylinders.
Install 1" x 3" stop bolts with two (2) hex jam nuts
in the top holes of the marker base. Using two
(2) other pivot pins, mount ladder sections to the
marker base arms and secure with 1/2" x 2 1/2"
bolts, lock washers, and hex nuts. Remove the
cylinder port plugs and extend hydraulic cylinder
rams out to align cylinder brackets with slotted
holes in ladder sections and connect with cylinder
bracket pins (1" x 10 3/4"), Use a 1" flat washer
on the outside of slotted area when installing
pins. Refer to drawing.
Attach two (2) springs from cylinder brackets to
the cross rods located by the slotted holes on the
ladder sections. These must be installed for
markers to work properly.
Install the marker arms in the first hole on the
ladder sections using 3/4" x 3 1/2" bolts, marker
arm spacer bushings (Refer to drawing), lock
washer, and hex nuts.
On the marker base arms --right and left, install
marker adjustment chain pins using 5/32" hair
pins. Attach marker chain weldment to the
adjustment chain pins using one (1) 1/2" hex
nylock nut on outside and one (1) 1/2" hex nut on
the inside. Let the eye bolt end of the weldment
loose so all take-up is still available. Run marker
chain down ladder sections, through the half loop
and pull tight, leaving very little slack in the chain.
Using 1/2" x 1 1/2" bolts with flat washers, lock
washers, and hex nuts, bolt chain to the marker
arms. (Refer to drawing to route chains.) The link
at the end of chain line may need to be spread
for 1/2" bolt. Fold marker up and back down to
make sure marker blade does not hit the ground.
The marker should be adjusted at this point, but
if the marker arm does not start out when the
ladder starts down, adjustment will have to be
made on the marker chain weldment. Fold
marker up and take the slack out of the chain
using the spring provided. (Refer to drawing.)
This is done so the slack chain does not damage
the grain box.
Attach adjustable marker stop assemblies to
bottom of ladder sections using 3/8" x 2 1/2" bolt
with lock washers, and hex nuts. DO NOT
TIGHTEN COMPLETELY AT THIS TIME.
Marker stops will need to be adjusted later to
keep marker blades from hitting ladders. Refer
to drawing.
Slide the adjustable marker arms into the end of
the ladder sections and secure with 5/8" x 1 1/2"
set screws and hex jam nuts. Finally, bolt the
marker blade assemblies to the adjustable
marker arms using 1/2" x 3" bolts with lock
washers, and hex nuts. TIGHTEN BOLTS AT
THIS STEP. Angle settings will be dependent on
field conditions and the amount of furrow desired.
Measure distance as required, and set adjustable
marker arms to proper positions.
For assembly of hydraulics, refer to hydraulic
sections in this owner's manual. After hydraulics
are complete, raise markers slowly to fill with oil.
Sequence several times to eliminate air in the
system. Be sure to check for leaks in the system.
Adjust marker stops so blades do not hit ladders
and tighten.
