CONTROLS AND OPERATION
Figure 1 Adjusting the Mower
WARNING: To avoid personal injury,
stop the engine, lower mower to the
ground and allow the blades to stop
before adjusting the mower.
1. Position the tractor on a level surface. Lock the
parking brake, stop the engine and remove the key.
2.Adjust tire pressure to 12psi in all turf tires, to
16psi in AG tires.
3.Set the lower link hitch point inner spread to
category 1 (26 7/8 inches) with adjusting check
chain. Heights of rear and left lower link hitch points
should be adjusted in same each other.
4.Set the gauge wheel and rear roller to the “setting
position” cutting height, Figure 3, 4,
5. Adjust the front links so the pins can be removed
easily from the mower.
6.Start the engine and raise the mower slowly.
Loosen the lift rod, if not previously done so that the
mower will not bind against the tractor or u~ stop.
7.Stop the engine and remove the key.
8. Adjust the tumbuckles on lift rod to obtain 5mm
(1/4") space between the plate (in front of deck) and
up stop and gauge wheels are equal height from the
ground. Tighten the lock nuts, Figure 2.
Figure 2 - Adjusting the Mower
9. If major changes are made in the cutting height,
repeat steps 5 to 8.
Reinstall the gauge wheel to the arm of the deck with
a clevis pin and hair pin clip. Select the desired
cutting height, as shown in Figure 3.

MOWER OPERATION
MAKING THE MOST OF YOUR MOWER
1 When Using your mower for the first time,
choose a smooth level area and cut in straight
and slightly overlapping strips.
2. The size and type of the area to be mowed will
determine the proper mowing pattern. Take
into account obstruction, such as trees, fences
and buildings. To keep grass cuttings off
fences, sidewalks, etc., it is advisable to go
around the outside of the area to be mowed
several times in a clockwise direction. To mow
the area remaining, work in a
counterclockwise direction so the cuttings are
dispersed onto the previously cut area.
3. Always keep the left side “Trimming side” of
the mower toward trees, posts or other
obstacles on the first trip around the obstacle.
4. Most lawns should be mowed to keep the
grass approximately 2 to 3 in. (51 -76mm)
high. Best results are obtained by cutting often
and not too short. To keep a green lawn,
never mow more than one third off the height
of the grass or a maximum of 1 in. (25mm) in
one mowing. For extremely tall grass, set the
cutting height at maximum for the first mowing,
then reset to the desired height and mow
again. Allow the grass to grow to three inches,
then cut off only the top inch.
5. On thick or springy grass or soft ground, the
mower rollers may sink into the ground giving
too low a cut. Readjust the cutting height to
obtain the desired height of cut.
6. For best appearance, grass should be cut only
when it is free of moisture.
WARNING: Some illustrations in the
manual show the mower with safety
shields removed to provide a better
view. The mower should never be
operated with any safety shielding
removed.
CUTTING HEIGHTS
WARNING: To avoid injury do not
operate the mower in the transport
position.
This mower can be adjusted to cut from 1 1/2" to
4 1/4" high. Cutting heights should be determined by
cutting conditions and personal preference. The
following recommendations will provide a guide for
height selection.
Lawns .......................................1 1/2" - 2 3/4"
Field Cutting .............................2 3/4" - 41/4"
To change from one cutting height to another it is
necessary to adjust the gauge wheel and rear roller
as following
1. Start the engine and pull the lift control lever
rearward.
2. Stop the engine, remove the key and lock the
parking brake.
3. After determining the cutting height, as shown
in Figure 4, remove the pin securing the
gauge wheels and reinstall the pin in the
desired position.
4. Change the latch position which mounts the
rear roller, if necessary.
5. Make sure that the gauge wheels and rear
roller are secured.
6. Lower the mower deck with the lift control
lever pushed forward.
7. lf desired, the mower can be carried with
minimum weight on the gauge wheels by
lowering the mower so that gauge wheels are
1/4 inch from the ground. Set the stop on the
tractor lift
CONTROLS AND OPERATION

control lever at that point. Returning the lift lever to
the stop each time will return the mower to the pre-
set height.
Figure 4 Approximate Cutting heights at various
wheels and roller settings
WARNING: Stop mower and tractor
immediately upon striking an
obstruction. Inspect mower and repair
any damage before resuming operation.
CUTTING SPEED
For best mowing results, it is important that blades
be run at maximum speed. Set engine throttle lever
in FAST position, thus providing proper blade speed
and maximum engine horsepower.
Choose a ground speed which will provide the
desired finish cut, maximum operator comfort and
will not overload the mower drive. A slower ground
speed will provide a smoother operating machine
UNEVEN TERRAIN
WARNING: Be careful when operating
tractor and mower on uneven ground.
In extremely uneven terrain rear wheel weights, front
tractor weights and/or front tire ballast should be
used to improve stability.
Pass diagonally through sharp dips and avoid sharp
drops to prevent “hanging up” of the tractor and
mower. Practice will improve your skills in
manoeuvring rough terrain.
Avoid sudden starts and stops when travelling up or
down hill.
Always mow down slopes, never up or across the
face. Avoid operation on steep slopes.
Slow down on sharp turns and slopes to prevent
tipping or loss of control.
GRASS DISCHARGE
This mower was designed to provide a strong
discharge to scatter clippings and prevent clogging in
heavy cuttings. When cutting lush, thick tall or wet
grass shift to a slow ground speed setting and/or
reduce width of cut to prevent possible belt damage.
FOR BEST CUTTING DO NOT MOWWHEN
GRASS IS WET. Wet grass will cause clogging and
produce unsightly clumping on lawn.
WARNING: To avoid injury from
thrown objects keep discharge guard in
position and secure at all times. The
under side of mower deck should be
cleaned out (sprayed with water) after
each cutting with the engine stopped
and blades not rotating.
In medium and heavy cuttings plan your mowing to
discharge clippings away from uncut grass. In light
mowing discharge clippings can be directed onto
uncut grass so cut area is free of clippings and
discharged grass is re cut into finer clippings.
If mower becomes clogged, back unit out of uncut
grass and try to clear deck by engaging the
P.T.O. with the deck in the highest position. If deck
does not clear itself STOP engine, remove starter
key and clean underside of deck using a stick or
scraper. If grass build-up is excessive remove
mower from tractor and clean underside of deck
thoroughly.
CONTROLS AND OPERATION

CUTTING PATTERNS
1 Cut counterclockwise patterns as shown in
Figure 5. The blade arrangement of the
mower will then eliminate streaks of uncut
grass when the tractor turns.
2. Changing direction wastes time. Plan to keep
mower moving forward as much as possible.
3. Plan for the longest straight runs that are
possible.
4. Save the close trimming for the end.
5. Sometimes it is easier to divide a large
irregular shaped area into smaller sections,
Figure 5 centre, to keep the mower working
more steadily or to keep from reversing turning
or repeating too often.
6. In a small area, where tight turns would cause
lost time in the centre if the normal round and
round methods were used, try the cutting
method in Figure 5 right. Make the second
pass down the centre of the area rather than
down the opposite side from the pass. This
allows you to swing wide at the end of each
pass and still cut all the grass with a minimum
of reversing.
WARNING: For safe operation, when
transporting the tractor, the mower must
be locked in the transport position. It is
also necessary to lock the mower in
transport position when using the tractor
with a loader or for 3 point lift
implement. Raise the mower and lock
the lift links using the hook and pin at
the rear bracket, Figure 15.
REMOVING MOWER FROM TRACTOR
1 Drive the tractor front wheels onto a suitable
block, such as a 2x6 board, and turn the
wheels full to the left.
2. Lock the brakes, stop the engine and remove
the key.
3. Set the cutting height gauge wheels and roller
at the lowest cut position (1 1/2").
4. Lower the mower deck.
5. Pull out the lock pin of the quick attachment
and push down the quick attach lever,
removing the front links from the front bracket.
6. Pull the hooks on the mower deck and remove
the front link assembly.
7. Remove the hair pin and clevis pin holding the
lift links to the mower deck. Lock the lift links in
the transport position with the hook and pin
provided, Figure 15.
8. Remove the universal joint from the P. T. 0.
shaft of tractor.
9. Pull the mower out from under the right side of
the ‘tractor. Be careful that the gauge wheel
spindles do not damage the front wheel drive
shaft and rubber boot while pulling the mower
from under four wheel drive tractor.
10 Three-point lift implements can now be used
without further disassembly of mower
attaching parts.
11. To install the mower, reverse the above
procedure.

STORAGE/TROUBLE SHOOTING
STORAGE
If your mower attachment is to be stored for an
extended period, it is advisable to do the following,
1. Remove grass build-up from underside of
deck.
2. Clean and wash entire mower deck.
3. Lubricate mower deck thoroughly. See
MAINTENANCE AND LUBRICATION
CHART.
4. Before operating mower again, check mower
belt and blades.
It is not advisable to store your mower in an area
where it will come in contact with fertiliser fumes.
Fertiliser fumes can damage your mower’s paint
finish.
TROUBLE SHOOTING
STREAKING: Leaving strips of uncut grass.
Possible Causes : Deck not level front to rear, dull
blades, tip of blade not square, blade lift worn off, low
engine RPM. Incorrect length replacement blade, not
enough overlapping between cutting rows, ground
speed too high, belt slippage, wet grass, blade
upside down.
SCALPING: Blades hitting dirt or cutting very close
to the ground.
Possible Causes: Ground speed too high, rough
terrain, deck mounted improperly blade upside down,
cutting too low, incorrect blade pitch, incorrect anti-
scalp roller setting.
STRINGERS: Occasional blades of uncut grass.
Possible Causes: Low RPM, plugged deck, dull
blades, ground speed too high, belt slippage, wet
grass, blade upside down.
UNEVEN CUT: Wavy appearance, high, low, high.
Possible Causes: Too much blade (deck) pitch, bent
deck, uneven ground, deck mounted improperly,
plugged deck, lift worn off blade, dull blades, bent
spindle mounting area, bent blades, ground speed
too high.
LUBRICATION AND MAINTENANCE

14
STEP CUT: Clear ridges in grass height. Possible
Causes Deck not level side to side, tire pressures
not equal, bent deck, bent blade, blade upside down,
deck mounted incorrectly, wrong spindle assembly,
internal spindle failure, bent spindle, wheels uneven.
The following is a check list of possible causes. They
are arranged in the best manner for eliminating any
of the preceding problems.
1 .Check that the deck is mounted correctly. The
correct pins are positioned and properly
clipped.
2. Blades should be sharp (see LUBRICATION
AND MAINTENANCE section) and mounted
correctly. Blades should be straight with
cutting edge down.
3. Engine RPM. Unit must be run at full engine
RPM. Reducing RPM slows blade tip speed
which reduces the cutting efficiency of the
mower deck.
4. The tire pressure must be correct. (see
MOWER ADJUSTMENT).
5. Check tension on drive belts as per Operator’s
Manual. A slipping belt will cause a loss in
blade tip speed.
6. Ground speed should be at about an average
walking pace, to suit height and density of
grass.
7. The length of grass being removed should be
no more than ½ the height of the grass before
it is cut.
8. Clean out any accumulation of grass and
debris from the underside of the mower deck.
9. Lubricate the idler control linkages and all
other pivot points.
10. The conditions of the ground. Uneven ground
may show scalping or uneven cutting. Raise
the cutting height of the mower deck.
11. Pitch or level of the deck and blades is
incorrect. Check for proper adjustment of the
gauge wheels and lift linkages.

ASSEMBLY OF MOWER TO TRACTOR
PREPARING THE TRACTOR
1 When optional large tires (AG5.00-12, AG6-12
with AG9 .5-16) are attached to the tractor, the
mower can not be mounted. Use standard
tires or turf tires only. The front wheel tread
setting in two wheel drive tractor should be
adjusted only as shown in Figure 23 when the
mower is mounted.
2. Set tractor lift links at the lift rods for full lift
height to prevent lift links from being too low
when mower is in operating position, Figure
20.
ATTACHING THE MOWER LIFT LINKS TO THE
TRACTOR
NOTE: Tighten all of mounting bolts and nuts with
