power drives, shut off the engine and
remove the ignition keys.
• Store the planter in an area away from
human activity.
• Do not permit children to play on or
around the stored planter.
• The planter should be stored in a dry and
dust-free location with the hydraulic
cylinders closed.
• Engage all safety devices for storage.
• Wheel chocks may be needed to prevent
the parked planter from rolling.
Performing Maintenance :
• Good maintenance is your responsibility.
• Make repairs in an area with plenty of
ventilation. Never operate the engine of
the towing vehicle in a closed building.
The exhaust fumes may cause
asphyxiation.
• Before working on the planter, stop the
towing vehicle, set the brakes, disengage
the PTO and all power drives, shut off
the engine and remove the ignition keys.
• Be certain all moving parts have come to
a complete stop before attempting to
perform maintenance.
• Always use the proper tools or
equipment for the job at hand.
• Never use your hands to locate a
hydraulic leak. Use a small piece of
cardboard or wood. Hydraulic fluid
escaping under pressure can penetrate
the skin. If injured by escaping
hydraulic fluid, see a doctor at once.
Gangrene can result. Without
immediate medical treatment, serious
infection and reactions can occur.
• Replace all shields and guards after
servicing and before moving.
• After servicing, be sure all tools, parts
and service equipment are removed.
• If the planter has been altered in any way
from the original design, the
manufacturer does not accept any
liability for injury or warranty.
Tire Safety :
• Inflating or servicing tires can be
dangerous. Whenever possible, trained
personnel should be called to service
and / or mount tires.
• Do not attempt to mount a tire unless you
have the proper equipment and
experience to do the job.
• Failure to follow proper procedures when
mounting a tire on a wheel or rim can
produce an explosion which way result in
serious injury or death.

• Carefully study and understand this
manual.
• Do not wear loose-fitting clothing which
may catch in moving parts.
• It is recommended that suitable
protective hearing and (eye protection)
sight protectors be worn.
• The operator may come in contact with
certain materials witch may require
specific safety equipment, relative to the
handling of such materials (examples :
extremely dusty, molds, fungus, bulk
fertilizers, insecticides, etc.)
• Assure that the planter tires are inflated
evenly.
• Give the planter a visual inspection for
any loose bolts, worn parts or cracked
welds, and make necessary repairs.
• Be sure that there are no tools lying on
or in the planter.
• Don’t hurry the learning process or take
the unit for granted. Ease into it and
become familiar with your new planter.
• Practice operation of your planter and its
attachments. Completely familiarize
yourself and other operators with its
operations before using.
• Do not allow anyone to stand between
the tongue or hitch and the towing
vehicle when backing up the planter.
During Operation :
• Beware of bystanders, particularly
children ! Always look around to make
sure that it is safe to start the engine of
the towing vehicle.
• No passengers allowed anywhere on, or
in the planter during operation.
• Keep hands and clothing clear of moving
parts.
• Do not clean, lubricate or adjust your
equipment while it is moving.
• When halting operation, even
periodically, set the tractor or towing
vehicle brakes, disengage the PTO, shut
of the engine and remove the ignition
key.
• Be especially observant of the operating
area and terrain – watch for holes, rocks
or other hidden hazards. Always inspect
the area prior the operation.
Do not operate near the edge of drop-
offs or banks.
Do not operate on steep slopes as
overturn may result.
Be extra careful when working on
inclines.

PLANTER PREPARATION
For the initial preparation of the planter,
lubricate the planter and row units as
outlined in the lubrication section of this
manual. Make sure all tires are properly
inflated, that all drive chains have the proper
tension, alignment and lubrication.
TRACTOR PREPARATION
Consult your dealer for information on the
minimum tractor horse power requirements
and tractor capability. Tractor requirements
will vary with planter options, tillage and
terrain.
One dual remote hydraulic outlet (SCV) is
required on models equipped with the
standard single valve hydraulic system. Two
dual remote hydraulic outlets (SCV) are
required on models equipped with the
optional dual valve hydraulic system.
PLANTER ATTACHMENT TO TRACTOR
Use the following six steps to attach your
planter to the tractor.
1. Adjust the tractor drawbar so it is 13
to 17 inches above the ground. Adjust the
drawbar so that the hitch pin holes is directly
below the center line of the PTO shaft. Make
sure the drawbar is in a stationary position.
2. Back the tractor to the planter and
connect them with a hitch pin. Make sure the
hitch pin is secured with a locking pin or
cotter pin.
3. Connect the PTO drive shaft to the
tractor. In addition to a standard 540 rpm
PTO, a 1000 rpm shaft is available.
CAUTION – Make sure that you
connect the proper end of the PTO to the
tractor. An arrow on the PTO indicates
the end of the constant velocity (double
clutch) that is attached to the tractor.
The following sticker is placed on your PTO
shaft for your safety...
DANGER – Rotating drive line
contact can cause death – keep away. Do
not operate without all driveline, tractor
and equipment shields in place ; without
drivelines securely attached at both ends,
and without driveline shields that turn
freely on driveline.
4. Connect the hydraulic hoses to tractor
ports in a sequence which is both familiar
and comfortable to the operator.
DANGER – Before applying
pressure to the hydraulic system, make
sure all connections are tight and hoses
and fittings have not been damaged.
Hydraulic fluid escaping under pressure
can have sufficient force to penetrate
skin, causing injury or infection.
CAUTION – Always wipe hose ends
to remove any dirt before connecting
couplers to tractor parts.

5. Raise the jack stand and remount
horizontally on the storage bracket.
6. Lower the planter to the planting position
and check that the planter is level (front to
back and side to side). If the hitch height is
too high or too low, disconnect the planter
and adjust the hitch clevis in an up or down
position as necessary.
LEVELING THE PLANTER
For proper operation of the planter and row
units, it is important that the unit operate
level.
Unless the tractor drawbar is adjustable for
height, the fore and aft level adjustment must
be maintained by the position of the hitch
clevis. Holes in the hitch bracket allow the
clevis to be raised or lowered. When
installing clevis mounting bolt, tighten hex
nut to proper torque setting.
With the planter lowered to proper operating
depth, check to be sure the frame is level
fore and aft (front to back and side to side).
Recheck once the planter is in the field.
It is also important for the planter to operate
level laterally. Tire pressure must be
maintained at pressures specified.
TIRE PRESSURE
Tire pressure should be checked regularly
and maintained as follows :
Transport Ground Drive : 7.50" x 20" - 40 psi
(2,7 bars)
Contact Drive : 4.10" x 8"- 60 psi (4 bars)
DANGER Rim and tire servicing
can be dangerous. Explosive separation
of a tire and rim parts can cause serious
injury or death.
Do not attempt to mount a tire unless you
have the proper equipment and
experience to perform the job. This
should only be done by properly trained
and equipped to do the job.
Maintain the correct tire pressure. Do not
inflate the tires above the recommended
pressure.
When inflating tires, use a clip-on air
chuck and extension hose long enough
to allow you to stand to one side, and not
in front of or over the tire assembly. Use
a safety cage to enclose the tire and
assembly when inflating.
Inspect tires and wheels daily. Do not
operate with low pressure, cuts, bubbles,
damaged rims or missing lug bolts and
nuts.

OPERATING SPEED
The operating speed needs to be selected
as a function of :
- The desired consistency in the row
- The ground conditions
- The density of the seed
A high speed is not conducive to accuracy,
especially in rough or rocky conditions which
causes the unit to bounce.
Likewise, a high seed density may cause the
disc to rotate fast, burdening the metering.
It should also be noted, and especially for
corn, the misshapen and angular seeds are
difficult to sow regularly, especially at high
working speeds.
A base speed of 3 ½ to 4 ½ mph (5/7 km/h)
assures good results for most seeds in the
majority of conditions. However when
planting corn at lighter population more than
6” (15 cm) between the seed, 5/6 mph (8/10
km/h) is quite possible.
For planting of high seed population such as
peanuts, edible beans, and kidney beans,
best results can be obtained by not going
faster than ¾ mph (4,5/6 km/h).
STANDARD RATE DRIVE
Seed planting rate charts are based on the
standard rate drive. The standard rate drive
uses a 30 tooth sprocket on each contact
drive tire.
IMPORTANT : After each sprocket
combination adjustment, make a field
check to be sure you planting at the
desired rate.
http://hespareparts.com

Operation

CONTACT DRIVE WHEEL SPRING
ADJUSTMENT
There are two down pressure springs on
each contact drive wheel. The down
pressure is factory pre-set and should need
no further adjustment.
The spring tension is set leaving 2 ¼"
between the spring plug and the bolt head.
TIRE SCRAPER
Due to the clearance between the wheel
assembly and the transport tire when a
planter is equipped with the 20" transport
tire, a tire scrapper should always be used.
This will help prevent a build-up of dirt/mud
between the wheel arm assembly and the
tire. Adjust the scrapper so it does not
contact the tire.
RIDGE PLANTING
For ridge planting mount the 20" tires in the
lower rear holes in the ground drive wheel
arm to raise the bar height 3". Mount the
contact drive wheel arm and springs in the
lower set of mounting holes in the wheel
module mount and raise the hitch height to
maintain fore and aft levelness.
TRANSMISSION ADJUSTMENT
Planting population rate changes are made
at the end mounted transmission. The
planter is designed to allow simple, rapid
changes in sprockets to obtain the desired
planting population. By removing the lynch
pins on the hexagon shafts, sprockets can
be interchanged with those from the sprocket
storage rod bolted to the transmission.
Chain tension is controlled by a spring-
loaded dual sprocket idler. The idler
assembly is adjusted with a ratchet arm. This
arm has a release position to remove spring
tension for replacing sprockets. The amount
of spring tension on the chain can be
controlled by the ratchet arm.
The planting rate chart on the following
pages of this section will aid you in selecting
the correct sprocket combinations.

state/provincial and local regulations.
WARNING: Always install safety
lockups on lift cylinders and make sure
wing lockup pins are in place to secure
wings at hitch.
TRACTOR PLANTING SEED
Planters are designed to operate within a
speed range of 2 to 8 mph. See “planting
and application rate charts”. Variations in
ground speed will produce variations in
rates.
NOTE : Due to a multitude of variables,
seed spacing can be adversely affected at
speeds above 5,5 mph.

FIELD TEST
With any change of field and/or planting
conditions, seed size or planter adjustment,
we recommend a field test be made to
ensure proper seed placement and operation
of row units. See “Rate Charts”, “Checking
Seed Population”, and “Checking Granular
Chemical Application Rate” at end of this
section :
 Check the planter for fore to aft and
lateral level operation. See “Leveling The
Planter”.
 Check all row units to be certain they are
running level. When planting, the row
unit parallel arms should be
approximately parallel to the ground.
 Check row markers for proper operation
and adjustment. See “Marker
Adjustment” and “Marker Speed
Adjustment”.
 Check for proper application rates and
placement of granular chemicals on all
rows. See “Checking Granular Chemical
Application Rate”.
 Check for desired depth placement and
seed population on all rows. See
“Checking Seed Population”.
After the planter has been field tested,
reinspect the machine :
 Hoses and fittings
 Bolts and nuts
 Cotter pins and spring pins
 Drive chain alignment

MARKER SPEED ADJUSMENT
The marker hydraulic system includes two
flow control valves. One flow control valve
controls the lowering speed of both markers
and one controls the raising speed of both
markers. To adjust marker speed, loosen the
jam nut and turn the control(s) clockwise or
IN to slow the travel speed and counter
clockwise or OUT to increase the travel
speed. The flow controls determine the
amount of oil flow restriction through the
valves, therefore determining travel speed of
the markers.
DANGER: The flow controls should be
properly adjusted before the marker
assembly is first put into use. Excessive
travel speed of the markers can be
dangerous and/or damage the marker
assembly.
NOTE: When oil is cold, hydraulics
operate slowly. Make sure all adjustments
are made with warm oil.
NOTE: On a tractor where the oil flow can
not be controlled, the rate of flow of oil
from the tractor may be greater than the
rate at which the marker cylinder can
accept it. The tractor hydraulic control
lever will have to be held until the
cylinder reaches the end of its stroke.
This occurs most often on tractors with
an open center hydraulic system.
On tractors with a closed center hydraulic
system, the tractor's hydraulic flow
control can be set so the tractor's detent
will function properly.
MARKER ADJUSTMENT
To determine the correct length at which to
set the marker assemblies, multiply the
number of rows by the average row spacing
in inches. This provides the total planting
width. Adjust the marker extension so the
distance from the marker blade to the center
line of the planter is equal to the total
planting width previously obtained. Both the
planter and marker assembly should be
lowered to the ground when measurements
are being taken. The measurement should
be taken from the point where the blade
contacts the ground. Adjust right and left
marker assemblies equally and securely
tighten clamping bolts. An example of
marker length adjustment follows:
Number of rows x Row spacing inches = Dimension between
planter center line and marker blade.
16 Rows x 30" Spacing = 480" Marker Dimension
The marker blade is installed so the concave
side of the blade is outward to throw dirt
away from the grease seals. The spindle
bracket is slotted so the hub and blade can
be angled to throw more or less dirt. To
adjust the hub and spindle, loosen the 1/2"
mounting hardware and move the bracket as
required. Tighten bolts to the specified
torque.
IMPORTANT: A marker blade assembly
that is set at a sharper angle than
necessary will add unnecessary stress to
the complete marker assembly and
shorten the life of bearings and blades.
Set the blade angle only as needed to
leave a clear mark.
A field test is recommended to ensure the
markers are properly adjusted. After the field
test is made, make any minor adjustments
as necessary.

PLANTER METERING UNIT NG PLUS 2
The NG Plus 2 metering unit in fig. 40 is
shown with standard features. Other options
are available for specific conditions or uses.
The drive chain is mounted as per fig. 41.
The individual disengaging of a metering unit
is possible by removing the lynch pin (rep.1)
of by disconnecting the vacuum hose.
The seed depth is adjusted by the
handwheel (rep.2) which changes the height
of the 2 depth wheels (rep.3) in relation to
the furrow disc openers (rep.4). A sticker
close to the handwheel, provided with a
gradual scale, ensures the uniformity of the
depth control on all row units of the planter.
The furrow opener and ground adjustment
system guarantees an accurate and regular
seed depth in all types of soil and conditions
because the depth wheels are positioned
perpendicular to the falling point of seeds.
The two rear press wheels (rep.5) affect only
the closing of the seed furrow. They float
independently and therefore do not have any
effect on the ground engaging. Their soil
pressure is regulated by the handwheel
(rep.6). This pressure has to be chosen
carefully in order to assure proper seed to
soil contact. Soil should be pressed over the
complete length of the row. This setting
depends on the type and humidity of the soil.
In order for the furrow disc opener to remain
properly cleaned, the 2 gauge wheels (rep.3)
have to touch (without pinching their outside
circumference). After starting up the planter,
the factory assembly may need
readjustment.
Adjust gauge wheel spacing by putting the
washers (rep.7) from one side of the
articulating arms to the other.
Adjust the pressure of the scrapers of discs
by tightening or loosening the bolts (rep.8).
Before and during each new planting
season, check if the seed tubes (rep.9) are
in good condition as consistent and regular
seeding will depend on this. Do not hesitate
to replace them if they are worn or damaged.
To replace them, remove pin (rep.10) after
removing the gauge wheel and furrow disc
opener on one side (Fig.42).
The function of clod removers (rep.11) is to
clear the surface of the soil but not to plow a
furrow. One use of the front brace of the clod
remover is to slice open hard soil and move
stones away from the track of the disc
opener. They need to be adjusted
accordingly. Using them in stony soils may
be a problem because they can cause
clogging and blocking. In this case it is better
to choose an assembly with a flexible
support bracket (fig. 43) which is efficient in
difficult soil conditions.

METERING BOX
The plastic wear gasket 5 on which the seed
disc rotates should be smooth and in good
condition. Under normal operating
conditions, it should be replaced only after
500 to 1000 ha (1250 to 2500 acres). The
metal brace 7 should be positioned with its
tab notched in the hole of the housing. The
outer edge of the plastic wear gasket is then
rotating , and is then held in position by cup
6 and 3 bolts. (Fig.33)
NOTE : Thoroughly clean the metering
box housing, before installing a new wear
gasket. Any residue left from previous
use will not allow the gasket to fit in the
proper position.

A sheet metal shutter 1is mounted inside
the cover B. This shutter regulate the flow of
seeds coming from the hopper and provide a
constant and sufficient level in front of the
disc. According to the seed used, the shutter
as to be checked and adjusted at 2 different
positions before planting:
1. High position : For large seeds such as
corn , soybean, edible beans, peanuts,
cotton, etc.
2.Low position (fig.35) : For small seeds
such as sunflower, beet, sorghum, etc.
This position should also be used for large
seeds when the planter has to work for
several hundred meters (1000 or more) on
slopes of more than 20%.
The shutter is adjusted by lowering it after
loosening the two bolts 2. A small plastic
sheet 3located under the shutter is also
used to limit the level of seeds in front of the
disc .
Before beginning your season, make sure
that it is in good condition.
A special metering box cover with a larger
opening (to improve the seed flow into the
seed chamber), a large discharge channel
(to avoid blockage) , and a special less
aggressive seed scraper (to avoid skips) are
available for the planting of large seeds such
as peanuts, kidney beans and large squash.
A special metal shutter is available for
planting small seeds such as cabbage ,
rape seed, etc. to reduce the seed flow into
the seed chamber.
A special ejector block maybe needed to
eliminate bridging in the discharger channel
in the cover for large peanuts and large
squash seed.
The ejector block 4enables the seeds to fall
regularly. For this purpose, it is
recommended to check its conditions
periodically.

METERING ADJUSTMENT
Two factors influence the degree of seed:
1.The position of the seed scraper in relation
to the holes of the disc. It is therefore
necessary to adjust the eight of the scraper
as needed for each seed type.
2.The degree of suction (depression) at the
seed disc. It is therefore necessary to adjust
the degree of suction to the weight of the
seed to be planted;
Fig.36
The (patented) MONOSEM system allows a
unique adjustment (fig. 36-37).
• To adjust the height of the scraper
and at the same time
• To adapt the degree of suction to the
weight and size of the seed.
Fig.37
When the indicator 1 is positioned to the “+”
(fig 36) it raises the scraper over the holes of
the disc and increases the degree of suction
(closing the size of the hole 2) . This may
cause doubles if raised too high.
When the indicator 1 is positioned to (fig 37).
It lower the scraper over the holes and
reduces the degree of suction (opening the
size of the hole 2) . This may cause skipping
if too low.
A control window in the cover allows you to

An optional hydraulic drive for the turbofan is
available. You must then double check that
there is adequate oil flow for the turbofan to
run at 500 rpm. Use an rpm gauge to check,
placing it at the center of the lower pulley.
A vacuum gauge may also be mounted to
the turbofan. (The vacuum gauge is standard
equipment when ordering the hydraulic
drive).
