Set the lower link hitch point inner spread to
Category 1 (26 ¼ inches) with adjusting check chain. Heights of right and left lower link hitch points should be adjusted to the same height.
Set the gauge wheels and anti scalp rollers to the desired cutting height, Figure 4, 5, 6.
Adjust the front links so the pins can be removed easily from the mower.
Start the engine and raise the mower slowly.
Loosen the lift rod, if not done previously so that the mower will not bind against the tractor.
Stop the engine and remove the key.
Adjust the tumbuckle on lift rod to obtain 5mm
(½”) space between the plate (in front of deck) and up Stop, and right and left gauge wheels are equal height from ground. Tighten the lock nuts. Figure 3.
Figure 4 Reinstalling the Gauge Wheel
NOTE: ANTI-SCALP ROLLER
In some cases the mower may scalp while cutting grass on rough ground at low cutting height. The anti-scalp rollers at the centre of mower deck (front side 1, rear side 2) are adjustable. Set them at high position when using the lowest Cutting height (2"), and at low position at other Cutting heights.

MOWER OPERATION
MAKING THE MOST OF YOUR MOWER
1
2.
When using your mower for the first time, choose a smooth level area and cut in straight and slightly overlapping strips.
The size and type of the area to be mowed will determine the proper mowing pattern. Take into account obstructions, such as trees,
10.
If major changes are made in the cutting height, repeat the steps from item 5 to 8.
6
CONTROLS AND OPERATION
3.
4.
5.
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.
Always keep the left side “Trimming side” of the mower toward trees, posts or other obstacles on the first trip around the obstacle.
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.
On thick or springy grass or soft ground, the mower wheels 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 1/4” to
4 2/8” high. Cutting heights should be determined by cutting conditions and personal preference. The following recommendations will provide a guide for height selection.
Lawns
Field Cutting
1 3/8" - 3"
3" - 4 3/8”
To change from one cutting height to another, it is necessary to adjust the gauge wheels:
1.
Start the engine and pull the lift control lever rearward.
2.Stop the engine, remove the key and lock the parking brake.
4.
5.
3.After determining the desired cutting height, as shown in Figure 6, remove the pin securing the gauge wheels and reinstall the pin in the desired position.
Make sure that the gauge wheels are secured.
Lower the mower deck with the lift control lever pushed forward.
6.
If desired, the mower can be carried with minimum weight on the gauge wheels by lowering the mower so the gauge wheels are
½inch from the ground. Set the stop on the tractor lift control lever at that point. Returning the lift control lever to the stop will return the mower to the pre-set height and allow the mower to go no lower.
Figure 6 Approximate Cutting Heights at Various
Wheels Settings

REMOVING MOWER FROM TRACTOR
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 MOW WHEN
GRASS IS WET. Wet grass will cause clogging and produce unsightly clumpings 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.

CUTTING PATTERNS
1.
Cut counterclockwise patterns as shown in figure 7. The blade arrangement of the mower will then eliminate streaks of uncut grass when the tractor turns.
2.
3.
Changing direction wastes time. Plan to keep mower moving forward as much as possible.
Plan for the longest straight runs that are possible.
Save the close trimming for the end.
6.
Sometimes it is easier to divide a large irregular shaped area into smaller sections,
Figure 7 centre, to keep the mower working more steadily or to keep from reversing turning or repeating too often.
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 7 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.

LUBRICATION AND MAINTENANCE
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 of 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 pit9h, 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.
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.
3.
4.
5.
6.
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.
Tire pressure must be correct (see Mower
ADJUSTMENT).
Check tension on drive belts as per Operator’s
Manual. A slipping belt will cause a loss in blade tip speed.
Ground speed should be at about an average walking pace, to suit height and density of grass.
7.
8.
9.
The length of grass being removed should be no more than % the height of the grass before it is cut.
Clean out any accumulation of grass and debris from the underside of the mower deck.
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.
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 fastened.
2.
Blades should be sharp (see MAINTENANCE
AND LUBRICATION section) and mounted correctly. Blades should be straight with cutting edge down.
