SAFE OPERATION
Careful operation is your best insurance against an
accident. Read this section carefully before operating the
mower. All operators, no matter how much experience
they may have had, should read this manual, tractor
manual and other related manuals before operating
mower. It is the owner's obligation to instruct all operators
in safe operation.
B Before operation (Pre-operation)
A Operator
1. Do not operate the machine while under the influence
of alcohol, medication, other substances or while
fatigued.
2. Be thoroughly familiar with the controls and learn how
to stop quickly in an emergency. Know your equipment
and its limitations.
3. Do not wear loose, torn, or bulky clothing around
machine. The clothing may catch on moving parts or
controls, leading to the risk of accident.
Wear and use any additional safety items such as hard
hat, safety boots or shoes, eye and hearing protection,
gloves, etc., as appropriate or required.
4. Never allow children to operate the mower, even
under adult supervision.
5. Read and understand this manual and the tractor
operator's manual before operating mower. Allow only
a properly trained person to operate the tractor.
A Machine, blades and equipment
1. Never operate the mower without proper guards,
shields, and the grass catcher bag or discharge
deflector in place.
2. The mower is equipped with many safety devices.
Do not alter or remove any part of safety system for
your safety.
3. Keep all nuts, bolts and screws tight to be sure the
mower is in safe working condition.
4. Check the blade bolts at frequent intervals for proper
tightness.
5. Inspect the blades for wear and damage. A dull blade
can be sharpened, but a blade that is worn out, bent,
cracked, or otherwise damaged must be replaced.
6. KUBOTA recommends the use of ROPS and seat belt
in almost all applications.
Always use seat belt when the tractor is equipped with
a ROPS.
Never use the seat belt when the tractor is not
equipped with a ROPS.
7. When using the mower, detach the backhoe
beforehand. Otherwise the machine may get damaged
during operation.
8. Replace damaged or illegible safety decals.
See next page for required labels.
A Working area
1. Thoroughly inspect the area where the mower is to be
used.
Remove all stones, sticks, wires, bones and other
objects that could be thrown at high speed.
2. Keep the area of operation clear of all persons,
particularly small children, and pets.
All people and pets should be kept at a safe distance
from the work area.
B Operation
A Starting
1. Never start engine or operate levers from anywhere
other than the seat.
2. Before starting the engine, make sure that all levers
(including auxiliary control levers) are in their
"NEUTRAL" positions, that the parking brake is
engaged, and that both the PTO clutch lever and the
range gear shift lever (Hi-Lo) are disengaged.
A Operation
1. Keep bystanders at a safe distance from the machine
during mowing operations.
2. Do not stand on the mower.
3. While making turns in rough terrain, reduce tractor
speed.
4. Do not mow while in reverse unless absolutely
necessary and then only after inspecting of the entire
area behind the mower.
Be extra careful of children.
5. Upon striking a foreign object, stop and inspect the
tractor and the mower for damage. Repair the damage
before resuming operation.
6. If the mower discharge deflector becomes clogged,
stop the tractor; disengage the mower drive; shut off
the engine and remove the key, and clean out the
deflector before continuing.

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 clippings 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 clippings are
dispersed onto the previously cut area.
3. Always keep the left 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 to 80 mm 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 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 80 mm, then cut off only the top growth.
5. On thick or springy grass or soft ground, the mower
rollers may sink into the ground, resulting in the cut
being too low.
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.
CUTTING HEIGHT
To avoid serious injury or death:
A Never operate the mower in transport position.
1. To set the cutting height, move the hydraulic control
lever rearward to raise the mower to the highest
position. Turn the cutting height control dial to adjust
height.
2. Set the anti-scalp rollers' height as shown to keep
clearance between rollers and ground from 6 to 13
mm.
3. Lower the mower deck by moving the hydraulic control
lever forward.
4. Use the higher settings for mowing in a rough area or
when mowing tall grass. Lower settings should be
used only for smooth lawns where short grass is
desired.

MAINTENANCE
BLADE REPLACEMENT
To avoid personal injury:
A Wear heavy gloves or wrap end of blade with a
rag when you handle blades.
1. Remove the mower from the tractor (See "REMOVING
THE MOWER DECK" in "OPERATION" section.) and
turn it over to expose the blades.
2. Wedge a block of wood between the blade and mower
housing or use a box wrench over the pulley nut to
prevent the spindle from rotating while removing the
blade bolts; loosen the blade bolt as illustrated.
A The blade bolts have Right hand threads. Turn them
counterclockwise to loosen.
A To prolong the service life of the blades, reposition
them as shown in the figure below periodically.
(1) Block
(A) "LOOSEN"
A Use the proper metric size box or socket wrench to
tighten or loosen the blade mounting bolt.
(1) LH blade
(2) Center blade
(3) RH blade
The blade cutting edges should be kept sharp at all times.
Sharpen the cutting edges, if they resemble the blade in
figure (B). Replace the blades if they appear similar to the
blade as shown in figure (C).
3. To sharpen the blades, clamp the blades one at a time
securely in a vise.
Use a large mill file and file along the original bevel
until sharp.
4. To check the blade for balance, place a small rod
through the center hole. The blade should balance on
this rod. If the blade is not balanced, file the heavy side
of the blade until balance is achieved.
5. [RCK60B-23BX, RCK54-23BX]
Install the blade in position together with the lock
washer and two cup washers. Tighten them up with
the bolts.
A Make sure that the cup washers are not flattened out
or worn; this cause blade to slip excessively. Replace
two cup washers if either is damaged.
A Tighten the three blade bolts 98 to 117.6 N-m (10 to 12
kgf-m, 72 to 87 ft-lbs.) of torque.
(A) New blade
(B) Worn blade
(C) Cracked blade

4. Remove the belt from the tension pulley.
5. Remove the right hand bracket which mounts the gear
box to the mower deck and slip the belt over the top of
the gear box.
6. To install a new belt, reverse the above procedure.
A Tighten bracket bolts securely 77.6 to 90.2 N-m (8.0 to
9.2 kgf-m, 57.1 to 66.5 ft-lbs) of torque.
