Transporting
• Be aware of the height, length and width of
implement. Make turns carefully and be aware of
obstacles and overhead electrical lines.
• Always travel at a safe speed. Do Not Exceed 20
mph (32 kph).
• Use an agricultural tractor that is large enough with
sufcient braking capacity so that the weight of the
loaded equipment towed does not exceed 1.5 times
the weight of the tractor.
• Use ashing amber warning lights, turn signals and
SMV emblems when on public roads.
• Do not transport in poor visibility.
• The slow moving vehicle (SMV) emblem and
reectors must be secured and be visible on the
machine for transport.
• Avoid soft surfaces, the additional wing weight on
the centre wheels could cause the machine to sink.
• Ensure safety chain is attached correctly to the
towing vehicle and the hitch of the implement.
• Check that wings are rmly seated on transport wing
stops, and wing lift valve and opener valve are in
locked postion.
• Be familiar with and adhere to local laws.
Hydraulics
• Do not search for high pressure hydraulic leaks
without hand and face protection. A tiny, almost
invisible leak can penetrate skin, thereby requiring
immediate medical attention.
• Use cardboard or wood to detect leaks - never your
hands.
• Double check that all is clear before operating
hydraulics.
• Never remove hydraulic hoses or ends with machine
elevated. Relieve hydraulic pressure before
disconnecting hydraulic hoses or ends.
• Maintain proper hydraulic uid levels.
• Keep all connectors clean for positive connections.
• Ensure all ttings and hoses are in good condition.
• Do not stand under wings.

Application
The Morris CONTOUR DRILL utilizes independent
parallel link openers. Each opener moves independently
of the frame and each other to follow every contour of the
land closely. The unique design of the opener allows
the Morris CONTOUR DRILL to be used in a variety
of seeding applications from conventional to zero till
applications.
SAFETY FIRST
REFER TO SECTION 1 AND REVIEW ALL
SAFETY RECOMMENDATIONS.
Tractor
Tires
• Proper ballast and tire pressure are required when
pulling heavy implements.
• Consult your tractor operator’s manual and follow all
recommended procedures.

• Wipe all hydraulic ttings and couplers with a clean
cloth to avoid contaminating the system.
• Check that hydraulic reservoir is lled to the proper
level.
Drawbar
• Centre and pin in a xed position for easier hitching
and greater stability.
Warning
Do not permit smoking, sparks or an open
flame where combustible fuels are being used.
Keep the work area well ventilated.
Warning
Do not search for high pressure hydraulic
leaks without hand and face protection. A tiny,
almost invisible leak can penetrate skin, that
requires immediate medical attention.

Accumulator System Operation and Pre-Charge Information
• Always turn “Operating” valve out to bleed off/service
position and relieve hydraulic pressure from the
system before performing maintenance or repairs.
Note: Accumulator can store pressure even when
disconnected from tractor.
• The gas bladder in the hydraulic accumulator should
be pre-charged with dry nitrogen gas before being
mounted on the unit.
• Different accumulator pre-charge pressures will allow
for different ranges of trip out force, as shown in the
chart.
• Pre-charge pressure should be set for the most
common working conditions.
• Lower pre-charge pressures with higher operating
pressures will give longer lifting and lowering times.
HIGH-PRESSURE FLUID HAZARD
To prevent serious injury or death:
• Relieve pressure on hydraulic system before
servicing or disconnecting hoses.
• Wear proper hand and eye protection when
searching for leaks. Use wood or cardboard
instead of hands.
• Keep all components in good repair.

Setting Maximum System Pressure (Trip Out Force)
• To determine the approximate trip out force in pounds
on each shank, divide the system hydraulic pressure
in the circuit by 1.5.
For example: A system hydraulic pressure of 750 psi
(5171 kPa) would be approximately 500 lbs (227 Kg)
trip force at each shank.
Note: Due to the variation of friction effects, this
trip force is approximate.
• Maximum hydraulic operating pressure can be set
by dialing the reducing valve in to increase allowable
pressure, and dialing it out to decrease allowable
pressure. This adjustment is done in order to set
a maximum working pressure; pressure can be
decreased below the set point and increased back
up to the set point on the go from the tractor.
1. Ensure the “Operating” valve is set to operating
position and the “Openers” ball valve is set to
unlocked position to allow ow.
2. Begin by dialing the adjustment all the way out on
the “Pressure” valve.
3. Dial the “Pressure” valve setting in 1 full turn.
4. Operate the tractor remote to pressurize the
accumulator circuit. Once the pressure has
stopped climbing check the system pressure on
the gauge.
Do not exceed 4 times the nitrogen pre-charge
pressure or 1200 psi, whichever is the lower
number.

Note: Set “Pressure” valve pressure 100 - 150
Note : Operate system at the lowest system pressure
C2 Contour Air Drill August 2014 5-9
psi above the desired working pressure
in order to allow for pressure drop from
accumulator cooling and valve hysteresis.
System pressure will level off and hold after
approximately 1 minute.
5. If the pressure in the system is high enough
to achieve the desired trip out force, setting is
complete. If the pressure is too low, relieve the
circuit pressure using the tractor remote and
repeat steps 3 and 4 until the desired pressure is
achieved.
6. If the system pressure is too high, relieve the circuit
pressure using the tractor remote, and then dial
the “Pressure” valve adjustment out incrementally.
Repeat step 4 until the desired system pressure
has been reached.

Relieve System Pressure
To bleed all pressure from Opener hydraulic system:
• Open “Operating” valve to service/bleed-off
position.
• Lift openers to transport position.
• Put tractor remote in “oat” position.
• Let openers drop and pressure go to 0 psi (or near
0 psi) on gauge.
• Lift openers to transport position and lock
“Openers” valve.
Normal Operation
• Set operating pressure as described under “Setting
Maximum System Pressure”.
• Ensure the “Operating” valve is turned in to operating
position and the “Openers” ball valve is set to
unlocked position to allow oil ow.
• With the Contour Air Drill moving forward, lower
openers into the ground. Hold tractor hydraulic
lever until the maximum preset operating pressure is
reached (see “Setting Maximum System Pressure”).
This ensures that all of the openers are fully charged
and engaged.
• When turning at head land, the openers do not need
to be completely cycled from working to fully lifted
position. The openers can be lifted just to the point
that they do not contact the ground. This will reduce
the time required to fully recharge the hydraulic
accumulator to the preset operating pressure.
• Avoid sharp turns with drill in ground. Turns sharp
enough to cause the inside openers of the air drill
to reverse direction may cause openers to plug.

Pressure Adjustment (On the go)
Pressure can be changed on the go to adjust for variable
eld conditions by using the tractor remote.
In order to lower the accumulator pressure on the go,
the “Operating” valve must be turned out to the bleedoff/service position.
Note: Operating pressure may drop more than
the 100 psi (689 kPa) described under
“Setting Maximum System Pressure” when
the “Operating” valve is set to the bleedoff/service position. This is dependant on
tractor valve leakage.
• Screw “Operating” valve out to open position for “on

Operate the openers as usual:
• With the Contour Air Drill moving forward, lower
openers into the ground. Hold tractor hydraulic
lever until the maximum preset operating pressure is
reached (see “Setting Maximum System Pressure”).
This ensures that all of the openers are fully charged
and engaged.
Operation
Important

Work Switch
(Optional equipment)
The pressure work switch activates the Air Cart Metering
system by the hydraulic pressure on the opener lift side.
When the openers are raised the switch opens at a
pre-set pressure turning off the Air Cart metering and
when lowered the switch closes at the pre-set pressure
to turn on the metering.
The pre-set Factory set point meets most operators’
preference. If the turn ON and OFF time needs to be
adjusted follow the procedure below:
• Remove cover from back of switch.
• Insert a 3/32” allen wrench into the adjustment screw
opening. Turn the screw clockwise to increase the
set point or counter clockwise to decrease.
- Increasing set point will cause the metering system
to turn ON quicker. This will also cause the
metering system to turn OFF later.
- Decreasing set point will cause the metering
system to turn ON later. This will also cause the
metering system to turn OFF quicker.

General Guidelines
The results obtained from the Morris Contour Drill are
directly related to the depth uniformity of the unit. Worn
points, uneven tire pressures, and bent shanks must be
avoided to obtain optimum eld results.
• Operating depth should be uniform at all opener
locations, when spot checking the implement in the
eld.
• Check openers running in tractor or air cart tracks
and adjust depth accordingly.
• Repair or replace bent shanks. Bent shanks cause
openers to work at uneven depths and can cause
unnecessary ridging. See Maintenance Section.
• Keep tire pressure at the listed specications to
maintain proper level. See Maintenance Section.
• Have Air Drill moving forward before lowering into
ground to avoid plugging openers.
• Avoid sharp turns. Turns sharp enough to cause
the inside openers of the air drill to reverse direction
are not recommended. This may cause the seed
openers to plug.
Operation
TAKE SAFETY SERIOUSLY.
Do Not Take Needless Chances!
Caution
Care should be taken when
working near the air cart
while the fan is running.
Product blowing out of
the system could cause
personal injury.
C2 Contour Air Drill August 2014 5-15

Operation
Quick Tips
Note: Read the Operator’s Manual for detailed
operating and adjustment instructions.
Shank Trip Force
Shank trip force (lbs) is calculated by dividing the display
pressure by 1.5 (ex. 750 psi display pressure = 500 lbs
shank trip force). Shank trip out pressure is generally
set at the minimum pressure that keeps the shanks
solid in the vertical position and prevents them from
repeatedly “tripping out”, while still providing adequate
packing. Maximum recommended shank trip out
pressure is 1200 psi.
Packing Force
Packing force is proportional to shank trip out force
and is roughly 1/3 of the shank trip force (ex. 500 lbs
shank trip force would give approximately 167 lbs of
packing force).
Hydraulic System
The Contour Air Drill uses a passive hydraulic system
(no constant ow is needed from the tractor during
seeding). Maximum operating pressure is set using
the reducing valve on the frame (see “Setting Maximum
System Pressure”). Pressure can be changed on the
go to adjust for variable eld conditions by using the
tractor remote (see “Pressure Adjustment”). If full range
adjustment of pressure is desired, the reducing valve
can be set at its maximum pressure and the operator
can then adjust pressure manually by watching the
pressure display and opener shanks.
Note: It is normal for the pressure to drop 100 to
150 psi from the initial set point while the
accumulator cools (the reducing valve can be
set higher to account for this initial pressure
drop). If the pressure continues to drop
quickly, check the machine for a cylinder,
fitting, or hydraulic line leak.

Lifting and Lowering the Openers
The openers do not need to be completely cycled from
working to fully lifted position while turning. Openers
can be lifted just to the point that they do not contact
the ground while turning, in order to save time by not
having to fully recharge the hydraulic accumulator with
uid each cycle (the display pressure won’t drop all the
way to zero). When transporting the drill, lift the openers
and ensure that the display pressure goes down to zero.

Quick Tips - Continued
Setting the Seed Depth
Seed depth is measured from the packed soil surface to
the seed. Set the seed depth on the drill by setting a few
openers across the drill to different depths and seeding
a test patch. Always seed the test patch at the same
ground speed and opener pressure that you intend to
maintain during regular seeding conditions. Then check
the seed depth of these openers, pick the depth setting
that you prefer, and set all openers to the desired letter
setting on the depth adjustment cam. The openers
perform best while seeding from 1/2” (13mm) to 1-1/2”
(38 mm) seed depth, but each customer is responsible
for choosing their own depth setting according to their
preferences and experience. Each adjustment notch
on the adjustment cam is 1/4” (6.4 mm) adjustment.
Shallow depth settings can be consistently maintained
with the Contour Air Drill system.
Note: Be sure to check tractor and/or air cart tracks
to see if the added soil compaction has
affected the seed depth; the independent
openers can be adjusted separately to
compensate for wheel tracks.
Operation
Seeding Conditions
The Contour Air Drill is meant to be used as a minimum
to no-till seeding system and care should be taken
when attempting to seed into loose or pre-worked soil
conditions. Shallow seeding depth, reducing operating
speed and operating pressure may help reduce soil
throw and ridging in soft conditions.
Note: Soil throw onto adjacent seed rows also
occurs on conventional air drills with gang
style packers, but is less visible because the
gang packers pack all rows simultaneously
at the back of the drill.
Straw Management
Successful seeding starts at harvest. The height of the
straw should not exceed the row spacing of the seeding
unit. The combine should chop the straw and spread the
straw and chaff evenly across the entire swath width. A
heavy harrow may also be required to spread and break
down the straw after the eld has been harvested. If
the straw height does exceed the row spacing a mower
should be used to shorten the straw length.
IMPORTANT
The Paired Row Opener with the NH3 adapter
is intended to allow the operator the flexibility to
switch between granular fertilizer and NH3 without
having to change openers. The opener is not
intended to apply granular fertilizer and NH3 in
the same operation. Excessive gassing off of the
NH3 will occur in such an operation. Producers
are still able to place starter fertilizer with the seed.
Morris Industries shall have no obligation or
liability of any kind on account of the end-user
incorrectly using this opener.

Operation
Quick Tips - Continued
Air Drill Frame
The Contour Air Drill frame is a simple slab frame
system, designed to let the parallel link openers do
the work of depth control and leveling during seeding.
No leveling of the frame is required. During normal
operation of the drill there will be very little weight on the
rear tires of the frame. The rear tires may even leave
the ground while traveling through sharp gullies; this is

Wing Lift Hydraulics
The wing lift hydraulic system is controlled by a
parallel hydraulic system. A pressure compensated
Flow Control Valve is used to control the ow of oil to
the cylinders allowing both wings to fold and unfold
simultaneously. A hydraulic circuit Shut Off valve is used
to lock the hydraulic circuit and prevent any leak back,
this ensures the wings remain in transport.
Operation
WINGS
LOCKED
The Flow Control Valve is located on the main frame
and there are no adjustments associated with the valve.
The Shut Off valve is located on the front wing lift truss
for easy access.
To unfold the Air Drill, the oil ows to the Flow Control
Valve, from there to the butt end of all the wing lift
cylinders extending the shafts and lowering the wings.
All cylinders must be fully extended to ensure correct
operation of the machine.
Placing the unit into transport is the reverse of unfolding
the unit. Oil is fed to the shaft end of the cylinders
retracting the cylinders and lifting the wings into
transport position.
Note: When raising or lowering wings, do so in one
continuous motion until fully up or down. Do
not stop ow part way allowing wings to fold
on their own. This may disrupt the sequence
of operation.

Operation
Opener Hydraulics
The Contour openers can be operated using two methods as described in the operators manual as Normal Operation
and Pressure Adjustment (On the go).
The following is the oil ow for both operating types and can be used for problem diagnosis.
Normal Operation
The opener ball valve is in the unlocked position. This ball valve is open. The operation valve is screwed in fully to
the operating position. This needle valve is closed.
To lower the openers, oil ows through the hose to port “A” of valve block. The oil is allowed to ow simultaneously
through ports “D” and “F”. Port “F” charges up the accumulator to operating pressure set by the pressure valve. Port
“D” charges the butt end of the opener cylinders causing the openers to lower.
Once the operating pressure is reached the oil will stop owing.
From port “A” of valve block, oil ows through the pressure reducing valve, to the pilot operated check valve unseating
the check valve and out of Port “D” to the butt end of the opener cylinders causing the openers to lower. Simultaneously,
oil ows from the check valve through the directional lock out valve and out of Port “F” to the accumulator.
When all of the opener cylinders are extended to working position, the hydraulic pressure
continues to build in the accumulator, hydraulic lines, cylinders and at the reducing valve.
When the pressure has risen to what the reducing valve has been set to the reducing
valve closes, preventing a further increase in pressure.
When the hydraulic ow to the pilot operated check valve is stopped, the check valve
seats, holding the pressure in the opener circuit.
The oil returning from the gland side of the
cylinders ows to the opener ball valve into
port “E” of the valve block and out of port “B”
back to the tractor.

Normal Operation - Continued
To raise the openers, oil ows from the tractor hose to port “B” of the valve block and out of port “E” to the opener
valve and on to the gland side of the cylinders. Oil is also felt on the line that operates the pilot operated check valve.
This causes the check valve to open and allow return oil back to the tractor.
Oil from the butt side of the cylinders travels to port “D” and through the opened pilot operated check valve to the
pressure relief valve. Oil can not go through the relief valve in this direction and is directed to the one way check
valve. The oil then travels through the one way check valve to port “A” of the valve block.
The oil ows through the port “A” of the valve block and back to the tractor.
Oil is also felt on the line that operates the directional lock out valve. This causes the directional lock out valve to
close preventing the oil in the accumulator from returning back to the tractor. The directional lock out valve maintains
the pressure in the accumulator in this position.

Opener Hydraulics - Continued
Pressure Adjustment (On the Go) - Continued
Pressure adjustment on the go, requires input from the operator to function.
The operator will have selected the operation valve to be in the bleed off/service position.
The adjustable reducing valve (Pressure Valve) will be set to provide correct trip and packing pressure.
With the Contour Air Drill moving forward, lower openers into the ground. Hold tractor hydraulic lever until the maximum
preset operating pressure is reached. This ensures that all of the openers are fully charged and engaged. To reduce
operating pressure on the go:
• Place tractor hydraulic lever into “Float Position” until pressure drops to desired operating point.
• Release hydraulic lever once desired pressure is reached.
Note: If pressure drops too rapidly when tractor remote is put into oat, the “Operating” valve can be turned
in a few turns to reduce bleed-off speed.
To increase operating pressure:
• Operate tractor hydraulic lever to increase pressure.
With the tractor lever in the oat position the pilot operated check valve does not receive
any pilot pressure to open it and the directional lock out valve does not receive any
pilot pressure to close it.
The oil ows from the accumulator and the butt end of the opener cylinders through
the operation valve and the one way check valve back
to the tractor. When the tractor hydraulic lever
is released the oil is again trapped and the
pressure will be reduced. If the pressure
reduction is too great the operator will have
to pressure the system up to the desired
pressure.

CAUTION
BE ALERT
General
This section deals with two goals, maximum life and
dependable operation. Adopt a regular maintenance
and lubrication program. Care and sufcient lubrication
is the best insurance against delays.
SAFETY FIRST
REFER TO SECTION 1 AND REVIEW ALL
SAFETY RECOMMENDATIONS.
Safety
• Always shut off the tractor and remove key before
dismounting.
• Guard against hydraulic high pressure leaks with
hand and face protection.
• Never work under the implement unless it is in the
down position or transport lock pins are in place
and secured with hair pins. Do not depend on the
hydraulic system to support the frame.
• Always wear safety goggles, breathing apparatus
and gloves when working on seeder filled with
chemical. Follow manufactures recommended safety
procedures when working with chemicals or treated
seeds.
• Do not feed left over treated seed to livestock, treated
seed is poisonous and may cause harm to persons
or livestock.
Warning
Securely support any machine elements that
must be raised for service work.
Caution
Keep service area clean
and dry. Wet or oily
floors are slippery.

Tighten Bolts
• Before operating the machine.
• After the rst two hours of operation.
• Check tightness periodically thereafter.
• Use Bolt Torque Chart for correct values on various
bolts.
• Note dashes on hex heads to determine correct
grade.
Note: DO NOT use the values in the Bolt Torque
Chart if a different torque value or tightening
procedure is given for a specific application.
• Fasteners should be replaced with the same or higher
grade. If higher grade is used, only tighten to the
strength of the original.

Lubrication
Greasing pivot points prevents wear and helps restrict
dirt from entering. However, once dirt does enter a
bearing, it combines with the lubricant and becomes
an abrasive grinding paste, more destructive than grit
alone.
• Apply new lubricant frequently during operation to
ush out old contaminated lubricant.
• Use a good grade of lithium based grease.
• Use a good grade of machine oil.
• Clean grease ttings and lubricator gun before
applying lubricant.
Refer to the photos for grease tting locations.
1. Wheel Hubs
• Grease every 500 hours or seasonally, whichever
occurs rst.
2. Gauge Wheel Castor Pivot
• Grease every 100 hours.

Hydraulic System Trouble Shooting
If pressure can not be maintained in the hydraulic
system, or openers drop rapidly from transport position,
a leaky hydraulic cylinder (bypassing oil across the
piston seal) may be present. To locate a hydraulic leak
in the Contour Air Drill hydraulic system, the following
procedure can be used:
1. Remove pressure from the hydraulic system.
2. Check the drill frame and hoses to make sure that
the leak is not external (leaking oil out of the circuit).
3. Lift the contour openers into their raised position.
4. Lock the hydraulic ball valve marked “OPENERS”.
5. Watch the openers carefully across the drill and
locate the rst opener(s) to visibly drop down from
the raised position (NOTE: This is the general area
of the leaking cylinder, but the rst opener to drop
is not always the leaking cyinder.).
6. Unlock the “OPENERS” hydraulic ball valve and
lift the openers to the raised position and lock the
hydraulic remote in the raised position to apply ow
to the circuit for about ve minutes.
7. Let the hydraulic remote go back to neutral, shut off
the tractor, and then go and check the temperature
of the opener cylinders by feeling the cylinder
barrels. Start at the group of cylinders that were
located in step 5) and then work from the outer
openers in to center until a “hot” cylinder is located.
8. Under normal conditions the cylinders should
remain cool (ambient temperature or slightly above);
the opener with a “hot” cylinder barrel has the leaky
seal and should be serviced or replaced.

or openers drop rapidly from transport in a
short period of time.

Hydraulics
Refer to Section 1 regarding hydraulic safety. In addition:
• Inspect hydraulic system for leaks, damaged hoses
and loose ttings.
• Damaged hoses and hydraulic tubing can only
be repaired by replacement. DO NOT ATTEMPT
REPAIRS WITH TAPE OR CEMENTS. High
pressure will burst such repairs and cause system
failure and possible injury.
• Always place “Operating” valve into service position
and relieve hydraulic pressure from the system
before performing maintenance or repairs.
Note: Accumulator can store pressure even when
disconnected from tractor.
• Leaking cylinders - install a new seal kit.
• Fittings - use liquid Teon on all NPT hydraulic joints.
Do not use liquid Teon or Teon tape on JIC or
ORB ends.
• Hydraulic Hose Connections - when connecting the
hoses to the cylinders, tubing, etc. always use one
wrench to keep the hose from twisting and another
wrench to tighten the union. Excessive twisting will
shorten hose life.
• Keep ttings and couplers clean.
• Check the Tractor Manual for proper lter replacement
schedule.
Refer to the Trouble Shooting Section.
Maintenance
Contact your nearest Dealer for genuine repair parts.
Dealers carry ample stocks and are backed by the
manufacture and regional associations.
Caution
Dirt in the hydraulic system could damage
O-rings, causing leakage, pressure loss and
total system failure.
Note: Extreme care must be taken to maintain
a clean hydraulic system. Use only new
hydraulic fluid when filling reservoir.
Warning

Wing Lift Cylinder Shaft Protection
The steps summarized below should be followed when
protecting chrome plated shafting on equipment:
• Position the equipment as it will be stored, and
identify all the exposed portions of the chrome plated
shafts.
• Clean dirt and dust from the exposed portions of the
shafting using a dry cloth or a cloth which has been
dampened with an appropriate solvent.
• Prepare a mixture of 60% oil-based rust inhibitor and
40% Kerosene. Apply a thin coating of this mixture to
the exposed surfaces of the chrome plated shafting.
No. 1 fuel oil may be substituted for Kerosene. A
cloth dipped in the mixture can be used to apply the
coating.
• Inspect the shaft surfaces after six months and apply
additional corrosion preventative mixture.
• If the equipment is to be moved and then stored
again for an extended period of time, the steps above
should be repeated for all shafts that were stroked
during the move.
• Before retracting the cylinders the protective
coating should be removed, to prevent ne sand
and dirt that has accumulated in the coating, from
damaging the shaft seal. Under no circumstances
should sandpaper or other abrasive be used
to clean the surfaces. Plastic or copper wool in
combination with an appropriate solvent will remove
most of the dirt.
Storage
Caution
Dirt in the hydraulic system could damage
O-rings, causing leakage, pressure loss and
total system failure.
Removing From Storage
• Review Operator’s Manual.
• Check tire pressure (Refer to Tire Pressure List)
• Clean machine thoroughly. Remove coating from
exposed cylinder shafts (Refer to Wing Lift Cylinder
Shaft Protection).
• Lubricate grease fittings. (Refer to Lubricating
Section).
• Tighten all bolts to proper specications (Refer to
