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

3.12. 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.
3.13. 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.
3.14. 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.
3.15. Never rest a foot on the brake pedal. If so, the
brakes disc wear rapidly, which may lead to serious
accidents.
3.16. Travelling set with the cruise lever should be
restricted only to operations in specious, flat areas
with an unobstructed view and used with the range
shift lever always kept in the low speed position.
3.17. Never attempt to do the mowing operation without
the discharge cover in place or with the cover left
open.
3.18. Never attempt to operate without the drive shaft
cover in place.
3.19. Do not attempt to adjust the cutting height while the
engine is running.
3.20. 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.
3.21. 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.
3.22. 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.
3.23. Never allow grass or leaves to accumulate around
heated parts such as the engine and the muffler, or
this may cause a fire.
3.24. 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.

3.31. 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.
3.32. If you use the lawn mower for long time, make
sure to take rest every 2 or 3 hours.
3.33. 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.

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, Never use it
on a slope of more than “10°”. Even if using it on a slope
of less than “10°”, be sure to abide by the following
instructions.
A slope angle of 10° is specified with the front mowers
equipped with the attachments mentioned respectively .
- The front mower is not equipped with any attachments or
a cabin.
- The front mower is equipped with a standard mower
deck.
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 collector, a cabin, etc.,
never fail to ask your dealers 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: MSG83/521/GRAMMER)
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.
FIG. 12
14
SF310,370
14
4.4. Do 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. Be sure to shift the 4WD lever to the 4WD position.
4.7. Never use the cruise control during mowing operation.
4.8. Choose a low gear to prevent the need to stop or
shift gears on a slope.
4.9. Avoid sudden starting and stopping.
4.10. Mow up and down a slope; do not mow across it.
4.11. Mow a slope by moving slowly. Do not suddenly
change your speed or direction.
4.12. Do not turn on a slope unless it is necessary, and
then, turn slowly downhill, if possible.
4.13. If the tyres lose traction, disengage the cutting
unit(s) and proceed slowly, straight down the slope.
Do not apply the brake on a front mower that is sliding down a slope. Engage the clutch slowly and
always keep the front mower in gear, especially
when travelling downhill.
4.14. Do not use the grass catcher(s) while you are mow-
ing a steep slope.
4.15. Do not try to stabilize the front mower by putting
your foot on the ground.
4.16. 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
15
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 rearward 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 the attachments other than those
included in the specifications mentioned below, ask
your dealers for advice.
Specifications of the ramps
6.6. Park the truck on hard level ground. Hook the ramps
securely on the platform of the truck with the top of
the ramp level with the platform.
6.7. Drive the front mower carefully at the moment the
front mower moves from the ramps onto the platform, for it changes angles abruptly.
6.8. When the front mower is loaded on the truck, lower
the mower deck onto the truck bed, stop the engine,
apply parking brakes, and withdraw the starter key,
chock the wheels, and rope it securely to the truck.
Refrain from unnecessary abrupt starting, stopping,
and turning during transportation, or the front mower
may shift position on the truck, which is very dangerous.

SF310,370
7. WHEN FILLING WITH FUEL
DANGER : Fuel is highly flammable and explosive. T ake 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.
7.4. If you spill fuel, clean it up and do not attempt to
start the engine until the vapour has dissipated.
7.5. When fuelling under certain circumstances, a static
charge may develop and ignite the fuel.
7.6. Use only an approved fuel container to store fuel.
7.7. Do not store the front mower or the fuel container
near a source of open flame, such as a water heater.
7.8. Replace all fuel tank and container caps securely.
7.9. To prevent personal injury and property damage, do
the following:
- Always place fuel containers on the ground and
away from the vehicle before fuelling.
- Do not fill the fuel container(s) inside a vehicle or
on a truck or trailer bed.
- When practical, remove a fuel-powered the front
mower from the truck or trailer and refuel it with its
wheels on the ground.
- If it is not practical to do this, refuel the front mower
on a truck or trailer from a portable container, not
fuel dispenser nozzle.
- If you must use a fuel dispenser nozzle, keep the
nozzle in contact with the rim of the fuel tank or
fuel container opening until you have completed
fuelling.
8. MOUNTING AND DISMOUNTING OF THE MOWER
DRIVE SHAFT
The mower gear box is driven through a drive shaft with
universal joints from the front mower. When connecting or
disconnecting the shaft, follow the next instructions.
8.1. Lower the mower deck onto the ground, stop the

8.3. Make sure that the PTO shaft and mower blades
stop completely.
8.4. The drive shaft should be mounted or dismounted at
the front mower side. Never leave the shaft connected only at the mower side. If the PTO shaft be driven unexpectedly, the shaft will be swung around and
damage the front mower or cause serious accidents.
9. INSPECTION AND MAINTENANCE
9.1. Never start the engine in a closed place. Exhaust
fumes contain poisonous carbon monoxide, so sufficient ventilation should be provided when starting
the engine indoors.
9.2. Be sure to wear safety glasses and gloves when
servicing the front mower.
9.3. When servicing the front mower or mounting or dismounting the mower deck, place the front mower on
level, hard ground.
9.4. Service the front mower in a place sufficiently illuminated, or darkness may cause unexpected accidents.
9.5. Do not adjust or repair the front mower while the
engine is running.
9.6. When servicing the front mower or mounting or dismounting the mower deck, stop the engine and
Remove the key (if applicable) to prevent someone
from accidentally starting the engine and apply the
parking brakes
9.7. The engine, muffler, radiator, etc. are very hot just
after operation, so wait until those heated parts cool
down sufficiently to avoid burns.
9.8. Never remove the radiator cap while the engine is
hot or running. Wait until the engine cools down and
then relieve the radiator pressure by releasing the
radiator cap. Carelessly pouring cooling water into
the heated radiator can cause serious damage to
the radiator and the engine. Careless removal of the
radiator cap can cause serious injury because of
superheated water vapor.
9.9. Before servicing the front mower, be sure to turn the
PTO switch to the OFF position (
) and make sure
that the mower blades have stopped completely.
Rotating blades may cause serious accidents.
9.10. While adjusting the front mower, keep your fingers
away from all pinch points.

9.11. When servicing the front mower, use proper tools.
Using makeshift tools may lead to injuries or poor
service, which may result in unexpected accidents
during operation.
9.12. When removing a tire, chock other tires and support
the front mower securely. When installing tires, be
sure to tighten the wheel nuts to the specified
torque. Loose nuts may cause serious accidents.
9.13. When raising up the mower deck for service, raise
up it fully and apply the lift lock of hydraulic cylinder
to avoid lowering.
9.14. The cutting means(s) are sharp and can cut you.
Wrap the cutting means(s) or wear leather gloves
when you service them. On the front mower with two
or more cutting means, rotating one cutting means
may cause the other cutting means(s) to rotate.
9.15. Never step on the mower deck, or the mower deck
may be damaged or deformed, which may lead to
breakdown or accidents.
9.16. A first aid kit and a fire extinguisher should be kept
in a place always in instant access.
9.17. On the front mowers with hydraulic devices, hydraulic fluid escaping under pressure can penetrate and
seriously damage the skin, requiring immediate
medical assistance. Do not use your hand to check
for a hydraulic leak; use a piece of cardboard. Be
sure to consult your dealer about the hydraulic and
fuel injection system troubles.
9.18. If any hydraulic fluid is injected accidentally into the
skin, it must be removed within a few hours by a
doctor familiar with this type of injury.
9.19. Never allow grass or leaves to accumulate around
heated parts such as the engine and the muffler, or
this may cause a fire.
9.20. Replace any worn or damaged parts with the manufacturer’s recommended parts.
9.21. To reduce the fire hazard, keep the engine, muffler
(silencer), battery area, and fuel storage area free of
debris.
9.22. If fuel has to be drained, this should be done outdoors.
9.23. Check the brake(s) on the front mower frequently
and adjust and service the brake(s) as required.
9.24. Replace faulty mufflers (silencers).

9.25. Do not change the engine governor settings or overspeed the engine. Operating an engine at an excessive speed can increase the risk of personal injury.
9.26. The grass catcher components are subject to wear
and damage, exposing you to moving parts or
thrown objects. Frequently check and replace them
with the manufacturer’s recommended parts when
necessary.
9.27. Be sure to reinstall the removed parts in place.
Never attempt to start the engine with any parts
removed.
9.28. Never attempt unauthorized modification of the front
mower as this could be very hazardous. Damaged
or worn parts should be replaced with ISEKI genuine spare parts. Unauthorized parts may cause
breakdown of the front mower, accidents, and ISEKI
warranty to expire.
9.29. Keep all fasteners tight, especially those that hold
the cutting means(s).
9.30. Check that all safety devices are in place and operating properly.

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 dis-
connect the earth battery cable (-), or you may get
an electric shock or be injured by sparks.
(3) Loose 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, muf-
fler 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 gases 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 fol-
lowing 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
engines. 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.

11. TIRES AND WHEELS
11.1. Be sure to keep tire pressures at the levels specified
in this manual. Excessively high tire pressure
may result in explosion, which may lead to physical
accidents.
11.2. If a cut is found in a tire and the cut reaches the cords,
do not use it. Such a tire may explode.
11.3. Before replacing or repairing tires, tubes, or rims,
consult your dealers ahead of time. Such operation
should be performed by trained mechanics.
12. BEFORE STORING THE FRONT MOWER
12.1. After operation, be sure to close the fuel cock to prevent fuel from spilling, as spilled fuel may catch fire.
12.2. Never allow grass or leaves to accumulate around
heated parts such as the engine and the muffler, or
this may cause a fire.
12.3. Be sure to remove the ignition key to prevent unexpected accidents caused by engine starting by
untrained persons or children.
12.4. When storing the front mower with the mower deck
attached, be sure to lower the mower deck on the
ground. Otherwise manipulation of the lift lever by
untrained person or children may cause unexpected
accidents.
12.5. Store the front mower in a place provided with sufficient illumination. Inspection and moving of the front
mower in a dark place may lead to unexpected
accidents.
12.6. When the front mower is to be stored in a closed
place like a garage or a barn, provide sufficient ventilation for exhaust gases. Exhaust fumes can be lethal.
12.7. To avoid fire hazard, keep the engine, muffler, battery, and fuel storage area free of grass, leaves, or
excessive grease.
12.8. Never cover a hot front mower just after operation
with a tarpaulin or the like, or the heated engine and
related parts may cause a fire.
