Operation on slopes
♦
Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not mow
it. The control of a ride-on machine sliding on a slope will
not be regained by the application of the brake.
Do not lift the grass container on a slope.
•
DO
(1) To avoid tip over, operate up and down slowly, not
across. Stay off hills and slopes too steep for safe
operation.
(2) Remove obstacles such as rocks, tree limbs, etc.
(3) Stay alert for holes in the terrain and other hidden
hazards. Keep away from drop-offs. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
(4) Follow KUBOTA's recommendations for wheel
weights or counterweights to improve stability.
(5) The weight of grass in the grass container may
increase the possibility of tip over. [if equipped]
(6) Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction.
(7) Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
(8) Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over or loss
of control.
(9) Use special caution when changing direction on
slopes.
(10) Shift "High - Low Gear Shift Lever" to the Low
position when mowing or operating on slopes.
DO NOT
(1) Do not turn on slopes unless necessary and then
turn slowly and gradually downhill, if possible.
(2) Do not use the machine on slopes of more than
14°.
(3) Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel
falls over the edge of a cliff or ditch, or if an edge
caves in.
(4) Do not mow on wet grass. Reduced traction could
cause sliding.
(5) Do not try to stabilize the machine by putting your
foot on the ground.
(6) Do not use the grass catcher on steep slopes. [if
equipped]
(7) Do not stop or start suddenly when going uphill or
downhill.
(8) Never "freewheel". Do not let the machine travel
downhill with speed control pedal at neutral
position.
(9) Do not use the trailer and the towing implement.
♦
Children
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are attracted to the
machine and the mowing activity. Never assume that
children will remain where you last saw them.
(1) Keep children out of the mowing area and under the
watchful care of another responsible adult.
(2) Be alert and turn the machine off if children enter
the area.
(3) Before and when backing, look behind and down for
small children.
(4) Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.
(5) Never allow children to operate the machine, even
under adult supervision. Local regulation can
restrict the age of the operator.
(6) Use extra care when approaching blind corners,
shrubs, trees, or other obstructions that might hide
children from sight.
♦
Operators, age 60 years and above
Data indicates that operators, age 60 years and above,
are involved in a large percentage of machine-related
injuries. These operators should evaluate their ability to
operate the machine safely enough to protect themselves
and others from serious injury.
♦
Stopping
(1) Make sure that the machine has come to a complete
stop before dismounting.
(2) Before dismounting, disengage the PTO, lower all
attachments, place all control levers in their neutral
positions, apply parking brake, turn off the engine,
and remove the key switch.
(3) Make sure that the machine and all attachments
have come to a complete stop before dismounting.
3. USING THE PTO
(1) Before installing or using PTO-driven equipment,
read the manufacturer's manual and review the
safety labels attached to the equipment.
(2) Wait until all moving components have completely
stopped before connecting, disconnecting,
adjusting, cleaning, or servicing any PTO-driven
equipment.

l If diesel fuel with sulfur content greater than 0.5% (5000 ppm) sulfur content is used, reduce the service interval for engine oil
and lter by 50%.
l NEVER use diesel fuel with sulfur content greater than 0.05% (500 ppm) for EXTERNAL EGR type engine.
l DO NOT use diesel fuel with sulfur content greater than 1.0% (10000 ppm).
l Diesel fuels specied to EN 590 or ASTM D975 are recommended.
l No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
uTransmission Oil:
The oil used to lubricate the transmission is also used as hydraulic uid. To insure proper operation of the hydraulic system and to
complete lubrication of the transmission, it is important that a multi-grade transmission uid is used in this system. We recommend
the use of KUBOTA UDT or SUPERUDTuid for optimum protection and performance.

Precaution at Overheating
■
Take the following actions in the event the coolant temperature
be nearly or more than the boiling point, what is called
"Overheating".
(1) Stop the machine operation in a safe place and keep the
engine unloaded idling.
(2) Don't stop the engine suddenly, but stop it after about 5
minutes of unloaded idling.
(3) Keep yourself well away from the machine for further 10
minutes or while the steam blown out.
(4) Checking that there gets no danger such as burn, get rid
of the causes of overheating according to the manual,
see "Troubleshooting" section. And then, start again the
engine.
Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Consult your local KUBOTA dealer concerning coolant for
extreme conditions.
(1) Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
(2) Before employing LLC-mixed cooling water, ll the
radiator with fresh water and empty it again. Repeat this
procedure 2 or 3 times to clean up the inside.
(3) Mixing the LLC
Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then ll into the radiator.
(4) The procedure for the mixing of water and anti-freeze
differs according to the make of the anti-freeze and the
ambient temperature. Refer to SAE J1034 standard,
more specically also to SAE J814c.
IMPORTANT:
When mixing the anti-freeze with water, the anti-freeze ●
mixing ratio is 50 %.

(5) Adding the LLC
1. Add only water if the mixture reduces in amount by
evaporation.
2. If there is a mixture leak, add the LLC of the
same manufacturer and type in the same mixture
percentage.
*Never add any long-life coolant of different
manufacturer. (Different brands may have different
additive components, and the engine may fail to
perform as specied.)
(6) When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anti-corrosive agent.
If mixed with the cleaning agent, sludge may build up,
adversely affecting the engine parts.
(7) KUBOTA's genuine long-life coolant has a service life
of 2 years. Be sure to change the coolant every 2000
hours or every 2 years whichever comes faster.
NOTE:
The above data represent industry standards that ●
necessitate a minimum glycol content in the concentrated
anti-freeze.
Checking and Cleaning Radiator to
■
Prevent Overheating
Daily or after every 5 hours of operation, check to be sure
the radiator screen and radiator core are clean. Dirt or chaff
on the radiator screen or radiator core decrease cooling
performance.
(1) Remove the radiator screen and panel screen, and
remove all foreign material.
(2) Remove the dust from between the ns and the tube.
(3) Tighten the fan drive belt as necessary. For this, refer to
page 38.

5. OPERATION
5.1 MAKING THE MOST OF YOUR
MOWER
(1) When using your mower for the rst 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 over 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 of the mower toward trees,
posts or other obstacles on the rst trip around the
obstacle.
(4) Most lawns should be mowed to keep the grass
approximately 50 to 80 mm (2 to 3 in.) high. Best results
are obtained by cutting often and not too short. To keep
a green lawn, never mow more than one third of the
height of the grass or a maximum of 25 mm (1 in.) in one
mowing.
For extremely tall grass, set the cutting height at
maximum height for the rst mowing, then reset to the
desired height and mow again. Allow the grass to grow
to 8 cm (3 in.), then cut off only the top inch.
(5) On thick, springy grass or soft ground, the mower rollers
may sink into ground giving too low a cut.
Adjust the cutting height to get the desired height of
cut.
(6) For best appearance, grass should be cut in the
afternoon or evening when it is free of moisture.
5.2 CUTTING HEIGHT
DANGER
To avoid serious injury or death:
Never operate mower in transport position. ●
(1) Check the both front gauge wheel pressures daily and
inate as necessary to prevent uneven cutting height.
(See page 13)
(2) To set the cutting height, adjust the front gauge wheels,
lift rods. Cutting height can be adjusted from 25 to 102
mm (1.0 to 4 in.).
NOTE:
For easy adjusting of the lift rods, place a wooden block ●
under the rear end of the mower deck before lowering the
mower deck.
Cutting height will change because of the ground ●
condition.
(3) Lower the mower deck by pushing the hydraulic control
lever forward. This lowers the mower deck from the
transport position to the operating position.
(4) Use the higher setting for mowing in a rough area or
when mowing high grass. Lower setting should be used
only for smooth lawns where short grass is desired.
Page 61
5.3 OPERATING MOWER
DANGER
To avoid serious injury or death:
Do not operate the mower without discharge ●
deectorproperlyboltedinplace.
WARNING
To avoid serious injury or death:
Clear the work area of objects which might be ●
picked up and thrown.
Do not direct the opening of the deector at●
bystanders or animals. Ejected objects may
cause injury. Plan your mowing carefully before
starting operations.
Keep bystanders and animals away from the ●
mowing area.
Be sure to disengage the front PTO clutch of ●
the mower before starting the engine.
9
(1) Keep the engine running at full throttle for best results.
Control travel speed by speed control pedal.
(2) During heavy duty use, operate the machine at a slower
ground speed or go over the area twice.
(3) Keep the mower deck and gauge wheels in the raised
position when the mower is not being used.
(4) The mower will not cut cleanly if the ground speed is too
high or if the blade speed drops due to an overload.
NOTE:
To prevent the engine from overheating, keep the ●radiator
and radiator net clean.
