SAFETY RULES
1. SAFETY RULES
Please pay particular attention to all boxed-parts in the text which have the sign .
This sign warns you to be careful when carrying out certain functions.
DANGER:
Indicates serious injury or death WILL result if instructions are not followed.
WARNING:
Indicates a strong possibility that serious injury or death could result if instructions are not followed.
CAUTION:
Indicates a possibility that minor injury can result if instructions are not followed.
NOTE: Gives helpful information.
Labels attached to certain parts of the Mower give important safety information.
Please read them carefully. Should a label detach itself or become illegible, contact your dealer for a replacement.
SAFETY INSTRUCTIONS
A) TRAINING
1) Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Learn how
to stop the engine quickly.
2) Only use the Mower for the purpose for which it was made, that is, the cutting and collection of grass. Any use
not specifically indicated in the instruction handbook can be dangerous and result in damage to the machine,
and will also result in the annulling of the warranty and the manufacturer declining all responsibility.
3) Never allow children or people unfamiliar with these instructions to use the Mower. Local regulations may
restrict the age of the operator.
4) Never use the Mower:
- When people, especially children, or pets are nearby.
- If the operator has taken medicine or substances that can affect his ability to react and concentrate.
5) Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their
property.
6) Do not carry passengers.
7) The operator of a Mower must carefully follow the driving instructions, particularly:
- The need for care and concentration when using Mowers;
- That control of a Mower sliding on a slope will not be regained by the application of the brake.
The main reasons for loss of control are:
- Insufficient wheel grip;
- Being driven too fast;
- Inadequate braking;
- The type of machine is unsuitable for its task;
- Lack of awareness of the effect of ground conditions, especially slopes;
- Incorrect hitching and load distribution.

SAFETY RULES
8) The Mower is equipped with a series of safety micro-switches and devices which must never be removed,
altered or tampered with. Removing these devices invalidates the warranty and the manufacture declines
any responsibility.
B) PREPARATION
1) While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
2) Thoroughly inspect the area where the equipment is to be used and remove all objects which may be
thrown by the machine (stones, sticks, metal wire, bones, etc.)
3) Before using/always carry out a visual inspection, particularly of the blades, seeing that the screws and
cutter assembly are not worn or damaged. Replace worn or damaged blades and screws in sets to
preserve balance.
4) Take care as the rotation of one blade can cause the other blade to turn.
C) OPERATION
1) Mow only in daylight or good artificial light.
2) Avoid operating the equipment in wet grass, where feasible.
3) Please consult machine operator’s manual for details on operation on slopes
4) Remember there is no such thing as a "safe" slope.
Travel on grass slopes requires particular care. To guard against overturning:
- It is advisable to use a front counterweight (supplied on request);
- Do not stop or start suddenly when going up or downhill;
- Always keep the machine in gear, especially when travelling downhill;
- Machine speeds should be kept low on slopes and during tight turns;
- Stay alert for humps and hollows and other hidden hazards;
- Never mow across the face of the slope.
5) Stop the blades rotating before crossing surfaces other than grass. When moving the Mower away from
the lawn disengages the blades and put the cutting plate into the highest position.
6) Never operate the Mower as a lawn mower with defective guards, or without safety devices, for example
deflectors and/or grass catchers, in place.
7) Before leaving the operator's position:
- Disengage the blades and lower the Mower.
8) Disengage blades, stop the engine and remove key:
- Before carrying out any work beneath the cutting deck or unclogging the chute;
- Before checking, cleaning or working on Mower;
- After striking a foreign object. Inspect the Mower for damage and make repairs before restarting
and operating the Mower;
- If the Mower starts to vibrate abnormally (immediately check and remove the cause of the vibration)

SAFETY RULES
9) Disengage drive to blades when transporting or not in use. Disengage the blades for them to stop before
emptying the grass-catcher.
10) Stop the engine and disengage blades:
a. Every time the grass-catcher is removed or replaced.
b. Before making height adjustment.
11) Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.
D) MAINTENANCE AND STORAGE
1) Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. Regular maintenance
is essential for safety and for maintaining performance levels.
2) Allow the engine to cool before storing in an enclosed space.
3) Check the deflector and grass-catcher frequently for wear and deterioration.
4) For reasons of safety, do not use the equipment with worn or damaged parts. Parts are to be replaced and not
repaired. Use genuine spare parts. Parts which are not of an equivalent quality can damage the equipment
and be dangerous for your safety.
5) Wear strong work gloves when removing and reassembling the blades.
6) Check the blades' balance after sharpening.
7) Take care as the rotation of one blade can cause the other blade to turn.
8) When the machine is to be parked, stored or left unattended, lower the cutting means.
9) Before any maintenance or repair, remove the ignition key.

OPERATION
MOWER OPERATION
IMPORTANT: Lack of operating knowledge can lead to accidents. Learn all Tractor and Mower controls and
how they work.
DANGER: To avoid personal injury:
● Do not operate the Mower
without discharge flap.
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
obstructions, 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 50 – 75 mm 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 25 mm 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
75 mm, then cut off only the top.
5. On thick or springy 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
view. The Mower should never be
operated with any safety shielding
removed.
Adjusting procedure
Check and adjust the mower in the following procedure before starting its operation for smooth cutting
operation.
WARNING: Before starting
adjustment, be sure to stop the
engine and make sure that the
cutting blade has stopped rotating.
1) Stop the tractor on a flat space and apply the parking brakes.

19
OPERATION
2) Lift the mower with the lift control lever of the tractor.
3) Stop the engine.
4) Adjust the front gauge wheel, rear gauge wheel and anti-scalp roller to obtain the desired cutting height.
Refer to page 22 "CUTTING HEIGHTS" for the cutting height adjustment.
5) Lower the mower with the lift control lever on the tractor.
6) Check to see that all the gauge wheels touch the ground. If not, adjust the front link length. When
adjusted correctly, the pin fixing the mower deck and front link can be easily pulled out.
7) Start the engine an lift the mower with the lift control lever of the tractor to the highest position.
8) Stop the engine.
9) Adjust the lift rod length so that the gap between the plate on the mower deck side and the stopper on
the tractor side is about 5mm. (STM60D-318/324 only.)
Figure 20
CUTTING HEIGHTS
This Mower can be adjusted to cut from 25 mm to 102 mm high. Cutting heights should be determined by cutting
conditions and personal preference.
The following recommendations will provide a guide for height selection.
Lawns 50 – 70 mm
Field cutting 60 – 100 mm
To change from one cutting height to another, it is necessary to adjust the gauge wheels and Anti-scalp roller.
