-1SAFE OPERATION
ENGLISH
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, the machine
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 machine
operator's manual before operating the mower. Allow
only a properly trained person to operate the machine.
A Machine, blades and equipment
1. Keep all nuts, bolts and screws tight to be sure the
mower is in safe working condition.
2. KUBOTA recommends the use of ROPS and seat belt
in almost all applications.
Always use the seat belt when the machine is
equipped with a ROPS.
Never use the seat belt when the machine is not
equipped with a ROPS.
3. Replace damaged or illegible safety decals.
See the following pages for required labels.
4. Do not operate the mower without all shields, guards
and ROPS in place.
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 the engine or operate levers from
anywhere other than in the seated position.
2. Before starting the engine, disengage the FRONT
PTO and shift the machine transmission into neutral.
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 machine
speed.
4. Upon striking a foreign object, stop and inspect the
machine and the mower for damage. Repair the
damage before resuming operation.
5. If the mower discharge deflector becomes clogged,
stop the machine; disengage the mower drive; shut off
the engine; set the parking brake and remove the key,
and clean out the deflector before continuing. (For side
discharge mower)
6. Slopes are a major factor related to loss-of-control and
tipover 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.
7. When mowing in rough terrain or in high grass, set the
mower at the highest cutting level to reduce the
possibility of the mower striking debris or hidden
objects.
8. Know what is behind you before backing up. Look to
the rear before and while backing up. Do not mow
while in reverse unless absolutely necessary and
make sure the area immediately behind you is clear of
obstructions or holes and small children. Use extra
caution when the machine is equipped with the grass
catcher. Your view to the rear is restricted.

MOWER MOUNTING
MOUNTING THE MOWER
To avoid personal injury:
A Before mounting the mower deck, read and
understand the use of the lift link lowering
speed control knob.
(See "Lift Link Lowering Speed Control Knob"
in "OPERATING THE MACHINE" section in the
operator's manual of the machine.)
A Place the PTO lever in the "DISENGAGE"
position.
A Place the High-Low gear shift lever in the
"NEUTRAL" position.
A The mower links (left hand, right hand) are
spring-loaded. Have an assistant hold the arm
in position when mounting the mower deck.
1. Move the mower deck under the mower links and
place the hydraulic lift lever in the "DOWN" position.
2. Attach the front end of the mower links to the mower
deck with clevis pins and set pins.
3. Start the engine, raise the mower deck, lock the lift link
lowering speed control knob, make sure the PTO is
"OFF" and shut off the engine.
4. Install the lift rods to the mower deck with the lock pins
and lower the mower deck on the ground.
[RCK72P-F39]
5. Attach the gas spring to the mower link with the clevis
pin and the rue ring cotter.
A When operating the mower, make sure the tilt lever is
unlocked.
A For tilting up the mower, see "MOWER TILT UP"
section in the operator's manual of the mower.
6. Pull back the coupler of the universal joint.
Push the universal joint onto the PTO shaft until the
coupler locks.
Slide the universal joint backward and forward to
check that the universal joint is locked securely.
A Finally pull the universal joint to see if it is locked tight
in position.
After mounting the mower deck, adjust the lift link lowering
speed.

9MOWER MOUNTING
ENGLISH
DISMOUNTING THE MOWER DECK
For dismounting the mower deck, reverse the above
procedures.
To avoid personal injury:
A The mower links (left hand, right hand) are
spring-loaded. Have an assistant hold the arm
in position when mounting the mower deck.
10 OPERATING THE MOWER
ENGLISH
OPERATING THE MOWER
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. (For side
discharge mower)
3. Always keep the left side of the mower toward trees,
posts or other obstacles on the first trip around the
obstacle. (For side discharge mower)
4. Most lawns should be mowed to keep the grass
approximately 50 to 80mm (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 25mm (1
in.) in 1 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 80mm (3 in.), 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 engage the PTO and blades in transport
position.
1. Check both the front gauge wheel pressures daily and
inflate as necessary to prevent uneven cutting height.
(See "FRONT GAUGE WHEEL" in "MAINTENANCE"
section.)
2. Cutting height can be adjusted from 25 to 129 mm (1.0
to 5 in.). To set the cutting height, adjust the front
gauge wheels and lift rods.
3. Adjust the anti-scalp roller as shown in the figure.

(2) Lift rod
(3) Front roller
(4) Anti-scalp roller
11OPERATING THE MOWER
ENGLISH
[2WD]
C For adjusting the lift rod tension
To adjust the tension, insert the set pin from A, B, C or D
as shown in the figure.
A If all the spacers are difficult to insert to the lift rod,
remove 1 or 2 spacers. Restore the removed spacer to
the right mower link with a clevis pin and a snap pin.
A For easy adjusting of the lift rods, place a wooden
block under the rear end of the mower deck before
lowering the mower deck.
A Cutting height will change because of the ground
condition.
4. Use higher settings for mowing in a rough area or
when mowing high grass. Lower settings should be
used only for smooth lawns where short grass is
desired.
5. Lower the mower deck by pushing the hydraulic
control lever forward. This lowers the mower deck
from the transport position to the operating position.
