manual.
2. BEFORE STARTING THE FRONT MOWER
2.1. Set up an operation plan with sufficient time
allowance. A tight plan may result in unexpected
accidents. Especially when operating the front
mower under extremely hot, cold, or humid
circumstances, set up an operation schedule or
method which will ensure operational safety.
2.2. Mow only in daylight or good artificial light.
Mowing in the dark may cause unexpected
accidents.
2.3. Thoroughly inspect the mowing area and remove
all objects from the mowing area that the front
mower can throw, such as stones, toys, sticks,
and wires, which may lead to serious accidents.
2.4 Ensure that there are no people or pets in the
area where you will mow. Keep children out of
the mowing area and under the watchful care of a
responsible adult.
2.5. Do not operate the front mower unless the
operator’s presence controls, safety switches,
and guards are attached and functioning properly.
2.6. Start the engine from operator's seat.
2.7. Before starting the engine, make sure that
everything is safe around the front mower and
put the traction drive in neutral, set parking brake,
and disengage the cutting unit (s). Otherwise,
unexpected accidents may occur.
2.8. Start the engine with the starter switch only.
Never attempt to start the engine by shorting the
terminals, or the front mower may move abruptly,
and result in unexpected accidents.
2.9. Do not run the engine in an enclosed area where
dangerous carbon monoxide fumes can collect.
Sufficient ventilation should be provided when
starting the engine in an enclosed area.
2.10. Make sure of safety around the front mower and
move slowly when starting. Abrupt starting may
cause unexpected accidents.

skilful enough to be able to stop the front mower
at will.
2.12. Use only attachments and accessories approved
by the manufacturer and install and operate them
as directed.
2.13. When your front mower is equipped with an
implement other than a standard mower deck
such as a collector, a cabin, etc., never fail to
ask your dealers about machine balance. Always
follow their advice.
2.14. Keep in mind that the operator or user is
responsible for the accidents or hazards caused
by the front mower to other people or their
property.
2.15. Inspect the front mower for wear or damage.
Replace any worn or damaged parts.
2.16. Especially before starting the mower, be sure
to perform advised pre-operation inspections
especially on the brakes and inspect visually
to see that the blade and blade tightening nuts
are not worn, damaged or loose. Replace worn
or damaged blade and nuts as an assembly to
preserve blade balance. Otherwise, poor braking
or scattered broken blades may result, which is
very dangerous.

3. OPERATION OF THE FRONT MOWER
3.1. When the front mower is running, stay away from
the discharge opening, the cutting unit(s), and all
moving parts.
3.2. During operation, never allow anyone, especially
children, and animals to be in the vicinity of
the front mower. Do not direct the discharge at
anyone.
3.3. When you are working with co-workers, be sure
to alert them by signalling before you take a new
action.
3.4. When operating the front mower, you should be
seated in the operator's seat properly, hold the
steering wheel by both hands, and look in the
direction in which the front mower advances.
Avoid looking a side or holding the steering wheel
by one hand during operation.
3.5. Always be sure to operate the front mower from
the driver's seat with seat belt. Never attempt to
get on or off the front mower while it is travelling.
3.6. Do not mow on wet grass. The front mower may
slide.
3.7. Slow down before turning the front mower.
Turning at high speed may cause the front mower
to turn over.
3.8. Never attempt to depress the dif-lock pedal while
turning around the front mower. Turning with the
dif-lock on may cause the front mower to turn
over.
3.9. Look down and behind you and ensure a clear
path before you move the front mower backward.
3.10. Do not mow while moving backward unless it is
absolutely necessary.
3.11. Never operate the front mower in terrain where
there are ditches, holes, or steps easy to
collapse. In such a place, the front mower could
turn over or fall.
3.12. Before making access to moving parts, stop the
engine, and keep your hands, feet, clothing,
accessories and etc. away so as not to be caught
in the moving parts of the front mower.
3.13. Be alert when you approach blind corners and
objects that may obscure your vision. Watch
for holes, ruts, or bumps. Tall grass can hide
obstacles.

3.14. Never rest a foot on the brake pedal. If so, the
brakes disc wear rapidly, which may lead to
serious accidents.
3.15. Travelling set with the cruise pedal should be
restricted only to operations in spacious, flat
areas with an unobstructed view and used with
the range shift lever always kept in the low speed
position.
3.16. Never attempt to do the mowing operation without
the discharge cover in place or with the cover left
open.
3.17. Never attempt to operate without the drive shaft
cover in place.
3.18. Do not attempt to adjust the cutting height while
the engine is running.
3.19. Adjust the cutting height with the gauge wheels
in accordance with the condition of the ground
surface at the working site. Mowing on rough
ground with low cutting height may cause
the blades to hit soil or stones, which is very
dangerous.
3.20. If you strike an object or if the front mower
vibrates abnormally, stop the front mower
immediately, wait for all moving parts to stop,
and inspect the cutting unit (s). Make all repairs
before you resume operation.
3.21. Be sure to keep the grass discharging part
clean. A clogged discharging part may cause the
discharge cover to open, resulting in scattering of
grass and stones, which is very dangerous.
3.22. Never allow grass or leaves to accumulate
around heated parts such as the engine and the
muffler, or this may cause a fire.
3.23. Before moving the front mower to another place,
be sure to stop the mower blades and lift up the
mower deck. Otherwise, they may hit stones and
scatter them around, which is very dangerous.
3.24. When driving over a levee or step, stop the
mower blades, lift up the mower deck, and move
the front mower straight to the levee and make it
climb over slowly. Avoid climbing over a levee too
high, or the front mower may fall sideways or turn
over.
3.25. Stop the cutting unit(s) when you are crossing
gravel areas
3.26. Watch for traffic when you are operating the
front mower near a roadway or when crossing a
roadway.
FIG. 9
FIG. 10

SF438,450

3.27. Never attempt to use the front mower to draw an
implement or a trailer. It is not designed to draw a
load.
3.28. Stay alert and stop the front mower if people or
pets enter the area.
3.29. Do not carry passengers
3.30. Never carry children, even when the cutting
means are not moving. Children may fall off
the front mower and become seriously injured
or prevent you from operating the front mower
safely. Children who have been given rides in the
past may suddenly appear in the mowing area for
another ride and be run over or backed over by
the front mower.
3.31. If you use the lawn mower for long time, make
sure to take rest every 2 or 3 hours.
3.32. When you hear thunder, stop the lawn mower
and move indoors immediately. If you cannot
move indoors, get to low place. Otherwise, you
can be struck by lightning.
3.33. Before stopping the engine, be sure to lower the
mower deck onto the ground, apply the parking
brakes and turn the PTO switch to the OFF
position.

4. OPERATION ON A SLOPE
DANGER : Slopes are a major factor related
to accidents with front mowers, resulting in
severe injuries.
We cannot recommend the front mower with mower
deck be operated on a slope. All slopes require extra
caution; no slope is safe.
You can lose control of the front mower on a slope
because of one of the following:
- the wheels lack traction; you are driving the front
mower too fast.
- you are not braking properly; the front mower type is
not suited for the task.
- you are unaware of the ground conditions (especially
slopes).
- you incorrectly hitch an attachment or distribute a load
If the front mower has to be used on a slope, DO NOT
use it on a slope of more than "12° ". Even if using it
on a slope of less than "12° ", be sure to abide by the
following instructions.
A slope angle of 12° is specified with the front mowers
equipped with the attachments mentioned respectively.
- The front mower is not equipped with any attachments
or a cabin than a standard mower deck and collector.
- The front mower is equipped with a standard mower
deck and collector.
Grass catchers and other attachments can change the
stability of the front mower. Follow the instructions for
adding weight to improve the stability of the front mower.
When your front mower is equipped with an implement
other than standard, such as a cabin, etc., never fail to
ask your dealer about machine balance. Always follow
their advice.
The ROPS is a safety device.
- Keep the ROPS in the vertical and locked position.
Always use the seat belt when you operate the mower.
Make sure the seat belt can be released quickly in an
emergency.
- The ROPS should only be folded if absolutely
necessary for storage. Do not operate the mower with
the ROPS in the folded position. There is no roll over
protection with the ROPS in the folded position.
- Do not use the seat belt with the ROPS in the folded
position.
- Do not remove the ROPS from the mower.
(Recommended seat: ACTIVO ALTO/962552646/
SEAT)
4.1. Be sure to wear a helmet during operation.
4.2. If you feel uneasy operating your front mower on
a slope, do not mow it.

4.3. Evaluate the terrain to determine what
accessories and attachments you will need to be
safe.
4.4. D o not mow near drop-offs, ditches, or
embankments. You can tip the front mower over
if a wheel is over the edge of a drop-off or if an
edge caves in. Uneven terrain can cause the front
mower to overturn.
4.5. Never perform mowing operation on wet grass.
4.6. Never use the cruise control during mowing
operation.
4.7. Avoid sudden starting and stopping.
4.8. Mow up and down a slope; do not mow across it.
4.9. Mow a slope by moving slowly. Do not suddenly
change your speed or direction.
4.10. Do not turn on a slope unless it is necessary, and
then, turn slowly downhill, if possible.
4.11. If the tyres lose traction, disengage the cutting
unit(s) and proceed slowly, straight down the
slope. Do not apply the brake on the front mower
that is sliding down a slope. Engage the clutch
slowly and always keep the front mower in gear,
especially when travelling downhill.
4.12. Do not use the grass catcher(s) while you are
mowing a steep slope.
4.13. Do not try to stabilize the front mower by putting
your foot on the ground.
4.14. Avoid stopping the front mower on a slope.
5. DRIVING ON PUBLIC ROADS
5.1. This front mower cannot be driven on a public
road without authorization by a local government
agency, etc. Therefore it may be illegal for the
front mower not only to travel on but also to cross
a public road.
5.2. When transporting the front mower on a public
road, load it on a truck or trailer.

CHAPTER 1. FOR SAFE OPERATION
13
6. LOADING ONTO OR UNLOADING FROM A
TRUCK
6.1. When loading the front mower onto a truck, turn
off the truck's engine, apply the parking brakes
to the truck, and chock the wheels to avoid
unexpected moving of the truck or trailer.
6.2. Pay sufficient attention to safety conditions
around the front mower and have it guided by
someone to assist the operator. Never allow other
persons to approach the front mower, especially
in front of or behind it.
6.3. When loading the front mower onto a truck, lift up
the mower deck fully and advance it straight at
sufficiently low speeds. Drive it backward when
unloading it from the truck or trailer.
6.4. If the engine stalls unexpectedly on the ramps,
depress the brake pedals immediately and roll the
front mower to the ground by releasing the brakes
gradually. Then start the engine and try again.
6.5. Use ramps with the same or better specifications
mentioned below. When the front mower is
equipped with attachments other than those
included in the specifications mentioned below,
ask your dealer for advice.
Specifications of the ramps
・Length........... more than 4 times the height of the
platform of the truck
・Width (effective width)..............more than 30 cm
・Required quantity...................................2 ramps
・Capacity (one ramp) ...............more than 900 kg
・Ramps should have anti-skid surfaces.

・The above specifications are effective with the
front mower with the following configurations.
-The front mower is not equipped with any
attachments or a cabin than a standard mower

7. WHEN FILLING WITH FUEL
DANGER : Fuel is highly flammable and
explosive. Take the following precautions.
7.1. Do not add or drain fuel indoors, while smoking,
or near a source of flame.
7.2. Do not remove the fuel tank cap or add fuel to the
tank while the engine is running or hot. Wait until
the engine cools down sufficiently.
7.3. Do not completely fill the fuel tank. Add fuel to the
tank until the level inside the tank is just below
the bottom of the filler neck. The empty space
allows the fuel to expand.

10. MAINTENANCE OF THE ELECTRIC SYSTEM
10.1. TO MAINTAIN ELECTRIC WIRING
(1) When servicing the electric wiring, stop the
engine without fail. Otherwise your hands or
clothes may be caught in or sandwiched between
rotating parts.
(2) Before manipulating electric parts, be sure to
disconnect the earth battery cable (-), or you may
get an electric shock or be injured by sparks.
(3) Loosen electric terminals or connectors may not
only lower electrical performance but also cause
short circuit or leakage of electricity, which may
lead to a fire. Promptly repair or replace damaged
wiring.
(4) Remove chaff or dust from the battery, wiring,
muffler or engine. Otherwise it could result a fire.
10.2. TO HANDLE THE BATTERY
(1) When working around the battery, avoid smoking.
The battery generates explosive hydrogen and
oxygen gasses when it is being charged. Keep
the battery away from sparks or open flames.
(2) The battery should be inspected before starting
the engine. Be careful not to touch the electrolyte
makes contact with the skin or clothing, wash it off
immediately with water and then consult a doctor.
(3) When replacing or inspection the battery stop the
engine and turn the main switch off, or electrical
parts may be damaged or unexpected accident
may occur.
(4) When disconnecting the battery cables, disconnect
the earth cable (-) first without fail. When
connecting the battery cables, connect the positive
cable (+) first. Disconnecting or connecting in
wrong order may lead to a short circuit or sparks.
10.3. TO HANDLE BOOSTER CABLES
When using booster cables, pay attention to the
following items for safe operation:
(1) Before connecting cables, remove the vent plugs.
This will lower the force in case of explosion.
(2) Before connecting cables, be sure to stop the
engine. Otherwise unexpected accidents may
occur.
(3) Use booster cables with sufficient electrical
capacity. A cable of inadequate capacity will cause
generation of heat, which may lead to a fire. (1) Negative cord (2) Positive cord
