Transport
Machinery Safely
Maximum transport speed for implement is 20 mph. Some rough terrains
require a slower speed. Sudden
braking can cause a towed load to
swerve and upset.
▲ Do not exceed 20 mph. Never
travel at a speed which does not
allow adequate control of steering
and stopping. Reduce speed if
towed load is not equipped with
brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that,
when fully loaded, weighs more
than 1.5 times the weight of towing vehicle.
Use A Safety Chain
▲ Use a safety chain to help con-
trol drawn machinery should it
separate from tractor drawbar.
▲ Use a chain with a strength rat-
ing equal to or greater than the
gross weight of towed machinery.
▲ Attach chain to tractor drawbar
support or other specified
anchor location. Allow only
enough slack in chain to permit
turning.
▲ Replace chain if any links or end
fittings are broken, stretched or
damaged.
▲ Do not use safety
chain for towing.

while operating machinery.
Avoid High
Pressure Fluids Hazard
Escaping fluid under pressure can
penetrate skin, causing serious
injury.
▲ Avoid the hazard by relieving
pressure before disconnecting
hydraulic lines.
▲ Use a piece of paper or card-
board, NOT BODY PARTS, to
check for suspected leaks.
▲ Wear protective gloves and safety
glasses or goggles when working
with hydraulic systems.
▲ If an accident occurs, seek imme-
diate medical attention from a
physician familiar with this type of
injury.

unattended with engine running.
▲ Do not dismount a moving tractor.
Dismounting a moving tractor could
cause serious injury or death.
▲ Do not stand between the tractor
and implement during hitching.
▲ Keep hands, feet and clothing
away from power-driven parts.
▲ Wear snug-fitting clothing to avoid
entanglement with moving parts.
▲ Watch out for wires, trees, etc.,
when raising implement. Make
sure all persons are clear of working area.
▲ Do not turn tractor too tight, caus-
ing implement to ride up on
wheels.
Tire Safety
Tire changing can be dangerous and
should be performed by trained personnel using correct tools and equipment.
▲ When inflating tires, use a clip-on
chuck and extension hose long
enough to allow you to stand to
one side–not in front of or over tire
assembly. Use a safety cage if
available.
▲ When removing and installing
wheels, use wheel-handling
equipment adequate for weight

4. Cycle cylinder completely in and out at least three
times to purge air from cylinder and hoses.
5. Fully extend cylinder and repin rod end.
6. Recheck tractor reservoir and fill to proper level.
Bleeding the Hydraulics
!
WARNING!
Escaping fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury.
Hydraulics must be bled of air before hitch operation. If the
hydraulics are not bled, the cylinders will move with jerky,
uneven motions. The hydraulics should be bled during initial hitch setup. If the hydraulics have not be bleed, or if you
replace a hydraulic component during the life of the drill,
follow these procedures.
Bleeding Tongue Cylinder
1. Check hydraulic fluid in tractor reservoir and fill to
proper level. Add fluid to system as needed. Tongue
cylinder capacity is one-half gallon (1.89 liters).

You can adjust spring tension on pivot-lock tubes. Refer to
Pivot Lock Tube Adjustment, “Adjustments,” page 15.
Transport Lift Cylinders
The transport-lift cylinders are rephasing hydraulic cylinders. After a period of normal use, the cylinders may get
out of sequence. If this happens, the hitch will lift unevenly
or one set of tires will not retract from the soil.
To rephase cylinders, raise drill completely and hold hydraulic lever on for a few seconds to allow cylinders time to
rephase.
Transporting
!
WARNING!
Towing the implement at high speeds or with a vehicle that is
not heavy enough can lead to loss of vehicle control. Loss of vehicle control can lead to serious road accidents, injury and
death. To reduce the hazard:
• Do not exceed 20 mph (32 kph).
• Install lock pins and channel as explained below.
• Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of the towing vehicle.
1. Check that implement is securely hitched to a sufficient tractor. Refer to Hitching Tractor to Hitch, “Prep-
aration and Setup,” page 7. Make sure safety chain is
secured to tractor.
2. Unload drill seed box before transporting if at all possible. The implement can be transported with a full box
of grain, but added weight will increase stopping distance and decrease maneuverability.
3. Check that tires are properly inflated. Refer to Tire In-
flation Chart,“Appendix,” page 24.
4. Know implement dimensions in transport position.
Choose a route that provides adequate clearance
from all obstructions. Refer to “Specifications and
Capacities,” page 23, for dimensions.
5. Hydraulically lift drill with transport-lift cylinders.
6. Install transport lock pins in vertical axle tubes.
7. Lock pivot-lock tubes for transport. Position tubes so

Coulter Down Pressure
The amount of coulter down force needed to cut a soil
groove varies with soil conditions. Adding weight or shortening the coulter spring increases coulter down pressure
and cutting force. Refer to Coulter Down Pressure, page
13, for more information on these adjustments.
Added Weight
In hard soil conditions where coulter penetration is limited,
you can add suitcase weights to brackets on hitch the
frame. Adding weight on the hitch frame provides the best
weight distribution for no-till drilling.You can add up to 100
pounds (45 kilograms) of additional weight per foot of hitch
width (1200, 1500 or 2000 pounds maximum). Place an
equal amount of weight on each weight bracket.
17212
Figure 3-1
Weight Brackets
Coulter Springs
Coulter-spring length is preset at the factory to 10 inches,
giving coulters an initial operating force of 400 pounds
(181 kg). This setting is adequate for many difficult no-till
conditions. For lighter no-till conditions where rocks or other obstructions are a problem, you can reduce coulter
down pressure to give coulters better impact protection.
Refer to the following chart for adjusting coulter down
pressure.

Seeding Depth
For accurate seeding-depth adjustments, you must adjust
your hitch and drill to match your soil conditions.
To adjust seeding depth:
1. Adjust coulters to desired depth. Refer to Coulter
Depth, page 13.
2. Adjust length of gauge-wheel turnbuckles on drill for
proper frame height. Refer to Leveling Drill,“Prepara-
tion and Setup,” in the drill operator’s manual.
3. Set lock plate on hitch level link to position that best
matches your field conditions. Refer to Lock Plate,
page 14.
4. Adjust hitch level link. Refer to Level Link Adjustment,
page 15.
Coulter Depth
A no-till coulter is mounted on the hitch directly ahead of
each opener on the drill. The coulters cut through heavy
trash and make a groove in the soil for the openers.
The center-pivot hitch is designed to allow coulters to penetrate approximately two inches (5 centimeters) into soil
when the tongue is level. However, hard soil or heavy crop
residue may cause shallow penetration. If coulter penetration is different than desired, depth can be adjusted
hydraulically for all coulters or manually for individual
coulters.
Hydraulic Control
Make the following adjustment when drilling in level
ground with the seed box half full.
1. Retract tongue cylinder to transfer weight to coulter
toolbar.
2. Set tongue cylinder so that coulters are at desired
depth. Note setting on cylinder gauge (see Figure 3-2)
so that you can return to the same depth.
NOTE: Use cylinder gauge only as a reference. Gauge
does not measure actual coulter depth.
10 1/2 in (26.67 cm) 175 lbs (79 kg)
10 1/4 in (26.03 cm) 300 lbs (136 kg)
10 in (25.40 cm) 400 lbs (181 kg)
9 3/4 in (24.77 cm) 525 lbs (238 kg)
NOTE: Do not reset coulter-spring length shorter than
9 3/4 inches (24.77 centimeters). Shortening springs
more than 93/4 inches(24.77 centimeters)may contribute
to premature failure of parts and warranty will be voided.

Coulter Mounting Height
You can change the depth of individual coulters by adjusting coulter-mounting height. If you adjust coulter height,
be sure to rebolt coulters vertically straight and correctly
spaced. To raise or lower individual coulters:
1. Loosen mounting clamps and adjustcoulter todesired
height. Do not lower coulter spring bar below top ubolts on coulter clamp.
2. To retighten clamps, refer to Figure 3-3. Snug hexhead clamp bolts (1) just until u-bolts are tight on each
side of spring bar.
3. Tighten nuts (2) on u-bolts.
4. Finish tightening hex-head clamp bolts.

Link in Rigid Position
Minimum Till, Average Soil with Hills and Terraces
For softer soils that have been tilled lightly and for drilling
over hills, contours, ditches or terraces, operate drill in limited-float position. See Figure 3-5. Leave lock plate unlocked and adjust level link so top link pin is at back of slot.
(Refer to Level Link Adjustment, page 15.) The limited-
float position allows hitch and drill to flex when traveling
over contours but transfers enough weight to drill for opener penetration in softer soils.

NOTE: Even when coulter is held securely, there may be a
gap between clamp halves.
Lock Plate
Set lock plate to match your field conditions. Lock plate is
located at rear of level link.
No-Till, Hard and Dry Soil
For maximum opener penetration, operate drill and hitch
in rigid position. See Figure 3-4. The rigid position is the
most common position for no-till seeding and is effective
for a wide range of field conditions. Lock plate down over
top link pin.

Level Link Adjustment
After setting lock plate to position that matches your field
conditions, adjust level link to level drill.
1. With drill box half-full of seed, lower drill and coulters
into field position in the field.
2. Observe drill and hitch from the side. The top of drill
box (1) should be parallel with the ground.
3. If necessary, adjust level link. Refer to Figure 3-7.
Raise drill and hitch, unlock lock plate and unpin level
link (2) from hitch. Loosen jam nut (3) and turn eye bolt
to shorten or lengthen link as necessary.
4. Repin link, lower drill and coulters and recheck top of
drill box. When drill box is parallel with ground, tighten
jam nuts.
Leaf Spring Adjustment
A leaf spring is located just ahead of the vertical pivot. See
Figure 3-8. The spring is designed to provide just enough
force to keep the hitch square and stable for turning at field
ends and to add stability for drilling in rough field conditions. Proper leaf-spring adjustment is important for
smooth implement operation.
To adjust properly, refer to Figure 3-8. Square tongue with
transport frame and adjust 3/8-inch u-bolts (1) on each
side until leaf-spring rollers (2) just make contact with roller pads (3) on transport frame. Make sure both right and
left sides are adjusted properly.
