Important Safety Information
Listed below are common practices that may or may not be applicable to the products
described in this manual.
Dig Safe - Avoid
Underground Utilities
 USA: Call 811
CAN: digsafecanada.ca
Always contact your local utility
companies (electrical, telephone,
gas, water, sewer, and others)
before digging so that they may
mark the location of any
underground services in the
area.
 Be sure to ask how close you can
work to the marks they
positioned.
2
Transport Safely
 Comply with federal, state, and local
laws.
 Use towing vehicle and trailer of
adequate size and capacity. Secure
equipment towed on a trailer with
chocks, tie downs, and chains.
 Sudden braking can cause a towed
trailer to swerve and upset. Reduce
speed if towed trailer is not equipped
with brakes.
 Avoid contact with any overhead
utility lines or electrically charged
conductors.
 Always drive with load on end of
loader arms low to the ground.
 Always drive straight up and down
steep inclines with heavy end of skid
steer on the “uphill” side.
Tire Safety
Practice Safe Maintenance
 Tire changing can be dangerous
and must be performed by
trained personnel using the
correct tools and equipment.
 Always maintain correct tire
pressure. Do not inflate tires
above recommended pressures
shown in the Operator’s Manual.
 When inflating tires, use a clip-on
chuck and extension hose long
enough to allow you to stand to
one side and NOT in front of or
over the tire assembly. Use a
safety cage if available.
 Securely support the attachment
when changing a wheel.
 When removing and installing
wheels, use wheel handling
equipment adequate for the
weight involved.
 Make sure wheel bolts have been
tightened to the specified torque.
 Understand procedure before doing

under the equipment, securely
support it with stands or suitable
blocking beforehand.
 Use properly grounded electrical
outlets and tools.
 Use correct tools and equipment for
the job that are in good condition.
 Allow equipment to cool before
working on it.
 Engage park brake when stopped on
an incline.
 Maximum transport speed for an
attached equipment is 20 mph. DO
NOT EXCEED. Never travel at a
speed which does not allow
adequate control of steering and
stopping. Some rough terrains
require a slower speed.
 As a guideline, use the following
maximum speed weight ratios for
attached equipment:
20 mph when weight of attached
equipment is less than or equal to
the weight of machine towing the
equipment.
10 mph when weight of attached
equipment exceeds weight of
machine towing equipment but not
more than double the weight.
 IMPORTANT: Do not tow a load that
is more than double the weight of the
vehicle towing the load.
 Disconnect battery ground cable (-)
before servicing or adjusting
electrical systems or before welding
on equipment.
 Inspect all parts. Make certain parts
are in good condition & installed
properly.
 Replace parts on this attachment
with genuine Kubota parts only. Do
not alter this attachment in a way
which will adversely affect its
performance.
 Do not grease or oil attachment

Important Safety Information
These are common practices that may or may not be applicable to the products described in
this manual.
Prepare for Emergencies
 Be prepared if a fire starts.
 Keep a first aid kit and fire
extinguisher handy.
 Keep emergency numbers for
doctor, ambulance, hospital, and
fire department near phone.
Wear Personal Protective
Equipment (PPE)
Avoid High
Pressure Fluids Hazard
 Wear protective clothing and
equipment appropriate for the job
such as safety shoes, safety
glasses, hard hat, and ear plugs.
 Clothing should fit snug without

entanglement with moving parts.
 Prolonged exposure to loud noise
can cause hearing impairment or
hearing loss. Wear suitable
hearing protection such as
earmuffs or earplugs.
 Operating equipment safely
requires the operator’s full
attention. Avoid wearing
headphones while operating
equipment.
 Escaping fluid under pressure
can penetrate the skin causing
serious injury.
 Relieve all residual pressure
before disconnecting hydraulic
lines or performing work on the
hydraulic system.
 Make sure all hydraulic fluid
connections are tight and all
hydraulic hoses and lines are in
good condition before applying
pressure to the system.
 Use a piece of paper or
cardboard, NOT BODY PARTS,
to check for suspected leaks.
 Wear protective gloves and
safety glasses or goggles when
working with hydraulic systems.
 DO NOT DELAY. If an accident
occurs, see a doctor familiar with

gangrene may
result.
Use Seat Belt and ROPS
Keep Riders Off
Machinery
911
Use Safety
Lights and Devices
 Slow moving tractors, skid steers,
and self-propelled machines can
create a hazard when driven on
public roads. They are difficult to
see, especially at night. Use the
Slow Moving Vehicle (SMV) sign
when on public roads.
 Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
4/12/19
 Kubota recommends the use of a
CAB or roll-over-protectivestructures (ROPS) and seat belt
in almost all power machines.
Combination of a CAB or ROPS
and seat belt will reduce the risk
of serious injury or death if the
power machine should be upset.
 If ROPS is in the locked-up
position, fasten seat belt snugly
and securely to help protect
against serious injury or death
from falling and machine
overturn.
 Never carry riders on skid steer
or attachment.
 Riders obstruct operator’s view
and interfere with the control of
the power machine.
 Riders can be struck by objects
or thrown from the equipment.
 Never use skid steer or
attachment to lift or transport
riders.

Important Safety Information
Listed below are common practices that may or may not be applicable to the products
described in this manual.
Avoid crystalline Silica
(quartz) Dust
Because crystalline silica is a basic
component of sand and granite,
many activities at construction sites
produce dust containing crystalline
silica. Trenching, sawing, and boring
of material containing crystalline
silica can produce dust containing
crystalline silica particles. This dust
can cause serious injury to the
lungs (silicosis).
There are guidelines which should
be followed if crystalline silica
(quartz) is present in the dust.
 Be aware of and follow OSHA
(or other local, State, or Federal)
guidelines for exposure to airborne
crystalline silica.
 Know the work operations where
exposure to crystalline silica may
occur.
 Participate in air monitoring or
training programs offered by the
employer.
 Be aware of and use optional
equipment controls such as water
sprays, local exhaust ventilation,
and enclosed cabs with positive
pressure air conditioning if the
machine has such equipment.
Otherwise respirators shall be worn.
 Where respirators are required, wear
a respirator approved for protection
against crystalline silica containing
dust. Do not alter respirator in any
way. Workers who use tight-fitting
respirators can not have beards/
mustaches which interfere with the
respirator seal to the face.
 If possible, change into disposable
or washable work clothes at the
work site; shower and change into
clean clothing before leaving the
work site.
 Do not eat, drink, use tobacco
products, or apply cosmetics in
areas where there is dust containing
crystalline silica.
 Store food, drink, and personal
belongings away from the work
area.
 Wash hands and face before eating,
drinking, smoking, or applying
cosmetics after leaving the exposure
area.
Handle
Chemicals Properly
 Protective clothing should be
worn.
 Handle all chemicals with care.
 Follow instructions on container
label.
 Agricultural chemicals can be
dangerous. Improper use can
seriously injure persons, animals,
plants, soil, and property.
 Inhaling smoke from any type of
chemical fire is a serious health
hazard.
 Store or dispose of unused
chemicals as specified by the
chemical manufacturer.

Operating Safety
! DANGER
To avoid serious injury or death:
• Never come in contact with power lines, utilities, gas lines,
or other hazards, above or below ground. They can cause
serious injury or death from electrocution, explosion, or
fire. Before digging, call dig safe 811 (USA only) so utility
companies can mark the location of underground services in
the area.
•
A crushing hazard that can cause serious injury or death
always exists around power equipment.
•
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment
supported by concrete blocks or hydraulics. Concrete can
break, hydraulic lines can burst, and/or hydraulic controls
can be actuated even when power to hydraulics is off.
•
The operator of this attachment must know how to control
the power machine with attachment and how to stop them
quickly in an emergency.
•
Do not drive up to anyone or an animal in front of a fixed
object such as a wall or bench. Never assume that the power
machine will stop in time.
•
Keep bystanders, pets, and livestock away from your work
area. Never allow anyone to go near or under the
attachment or its load. The attachment and/or load can fall.
•
Do not go near or under raised loader arms without first
securing loader arms in the raised position with an
approved lift-arm support.
•
Keep your head, arms, and legs inside the cab while
operating the power machine. Any extremity extended
outside the cab can be crushed by the loader arms and
attachment.
•
•
Never operate equipment from outside the cab.
Page 26
General Inspection
Operate hydraulic controls to verify control lever
movements function properly and equipment
movements are correct. Make necessary changes to
controls and hydraulic hook-ups before putting
equipment into service.
Use the skid steer’s alternate emergency exit when exit
passage through the front is blocked.
•
Do not use hand or foot controls for handholds or steps.
Using them for handholds or steps can activate the controls.
•
•
Keep mud, snow, ice, and debris out of foot controls.
If included, raise restraint bar and move controls until both
are locked and interlock system is activated.

Table of Contents
Section 3: Operating Procedures
•
Inspect interlock control system regularly and perform
required maintenance to keep it operating properly.
•
Allow only persons to operate this attachment who have
fully read and comprehended this manual, who are properly
trained to operate the attachment safely, and who are age 16
or older. Serious injury or death can result from the failure
to read, understand, and follow instructions provided in this
manual.
•
•
Never bypass or modify a safety device.
•
Never carry riders on the attachment or power machine.
Riders can obstruct the operator’s view, interfere with
control of the equipment, be pinched by moving
components, become entangled in rotating components, be
struck by objects, be thrown or fall from the equipment, etc.
•
Use steps, grab-handles, and anti-slip surfaces on the
power machine and attachment to get on and off the power
machine. Using unapproved stepping surfaces and/or
handholds can result in a falling hazard.
•
Operate only power machines equipped with a certified
Roll-Over Protective Structure (ROPS) and seat belt. Keep
folding ROPS in the “locked up” position when
appropriate. If ROPS is in the locked up position, fasten seat
belt snugly and securely to help protect against serious
injury or death from falling and machine overturn.
•
Keep load centered, even when stopped. This will optimize
load stability and protect against load shifting.
•
Do not abuse equipment. Incorrect use of the attachment
can damage equipment structurally and cause serious
injury or death.
•
Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
Replace parts only with genuine OEM parts. Kubota parts.
•
Check hitch fit-up frequently. An improper fit-up can cause
the attachment to come loose from the loader hitch plate
and fall.
•
Always shut power machine down following the “Shutdown
Procedure” provided in this manual before leaving the
operator’s seat.
Do not chain or strap loads to the loader arms, hitch, or
attachment. Hitting solid objects with a load fastened to the
attachment or machine can cause the operator to lose
control.
•
Consult your power machine’s manual for operating
capacity, lifting capacity, and operating specifications.
Exceeding rated capacities and specifications can result in
a roll-over or other serious hazard.
Do not use attachment to lift, carry, push or tow other
equipment and objects. It is not properly designed or
guarded for this use. The operator could lose control and
cause a tipping hazard.
•
Do not use attachment for lifting front end of skid steer off
the ground. Doing so can damage attachment and cause
injury.
•
Follow recommendations in the power machine Operator’s
Manual when parking or dismounting the power machine.
•
Lightweight power machines may need weight added to the
rear to maintain steering control and prevent forward
tipping or side tipping caused by a heavy front load. Consult
your power machine Operator’s Manual to determine
proper weight requirements and maximum weight
limitations.
•
Always lower attachment to ground level and fully close the
jaw before dismounting the power machine.
Be safe, lift only loads with the loader arms that can be kept
under control and contained. An uncontrolled load can
result in a serious injury or death.
•
Make sure the machine is stopped on solid, level ground
before raising load to dump. To maintain stability, raise
load only to the height necessary to complete the dump.
•
Never dump a load around gas lines, overhead power lines,
utilities, or other hazards that can cause serious injury or
death from electrocution, explosion, or fire.
•
Make sure all objects are contained and/or secured before
lifting. Do not lift a load that cannot be contained in the
attachment as the load can shift and fall.
•
Keep load positioned forward enough to prevent accidental
spillage on operator and power machine.
•
Keep load slightly tilted back to secure its weight against
the hitch frame. Rotating top of hitch frame back too far can
cause load to shift and fall rearward onto the machine and/
or operator. Rotating top of hitch frame forward too far can
cause load to shift and fall forward.
•
Use a “spotter” when it is hard to see in the direction you
are traveling and when placing a load that obstructs your
vision. A person or animal could be nearby in a blind spot.
! WARNING
To avoid serious injury or death:
• Keep body, body extremities, loose clothing, pull strings,
etc. away from pinch points such as rotating, extending,
and/or retracting components. Secure pinch point areas to
ensure they will not move before working on or near them.
•
•
•
•
•
Backup alarm must be in good working order to warn
others. Use a backup camera or rear-view mirror that is in
good condition to help see undesirable situations behind the
unit. Drive at a slower speed to compensate for blind spots.
Operate only power machines equipped with a certified
Roll-Over Protective Structure (ROPS) and seat belt.
Fasten seat belt snugly and securely to help protect against
serious injury or death from machine overturn.
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than
hands when searching for leaks. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.

•
•
Wear appropriate personal protective gear, including eye
protection when appropriate, when operating a power
machine without an enclosure or protective shield. Dust and
debris can get into the eyes.
Avoid exposure to dust containing crystalline silica
particles. This dust can cause serious injury to the lungs
(silicosis). Because crystalline silica is a basic component
of sand and granite, many activities at construction sites
produce dust containing crystalline silica. Trenching,
sawing, and boring of material containing crystalline silica
can produce dust containing crystalline silica.
Transport Safety
! DANGER
To avoid serious injury or death:
Keep attachment, loader arms, and/or load away from
overhead electrical power lines. Place an orange warning
sign under overhead lines indicating type of danger above.
! WARNING
To avoid serious injury or death:
• Follow all safety precautions when transporting a load. Not
using safe transporting methods can damage the equipment
and cause serious injury or death.
•
Always transport loads as close to the ground as possible
without hitting objects. A load carried high could shift
causing the load to fall, tipping of the machine, and/or loss
of control.
•
Always transport over ramps and inclines with the heavy
end of the power machine on the “uphill” side. This may
require one to drive up and back down inclines.
•
Always travel straight up and straight down inclines. Make
turns only on level ground.
•
Transporting loads across inclines, over ramps, on bumpy,
soft, or slippery surfaces reduces machine stability and lift
capacity. Transporting and lifting loads under these
conditions is extremely dangerous. Follow all transport
instructions in your power machine Operator’s Manual.
•
When traveling on public roadways, travel in such a way
that faster moving vehicles may pass safely. Use accessory
lights, clean reflectors, and a slow moving vehicle sign that
is visible from the back to warn operators in other vehicles
of your presence. Always comply with all federal, state, and
local laws.
Combination Bucket Operation
! WARNING
To avoid serious injury or death:
• Keep bystanders at a safe distance when entering and
picking up a load. Objects can shift or be thrown suddenly
as the bucket makes contact with the load causing serious
injury or death.
•
Enter the pick-up zone carefully making sure no objects will
come back into the operator’s space causing serious injury
or death.
16
•
Read and understand all safety alerts under “Operating
Safety” on page 14.
IMPORTANT: Do not ram bucket into a pile or hook
a chain to the bucket to secure a load. Doing so can
damage the bucket.
Operating Tips
1.
Go slowly when first learning how to operate the
bucket and loader.
2. Keep the work area small and travel distance short to
make the job more efficient.
3. When setting up a work site, choose a site that is
level, clear of low hanging electrical lines, and free of
obstructions such as trees, fences, and buildings.
4. When possible, save cycle time by making “skid”
turns going forward instead of backing up.
5. Reduce number of cycles by filling the bucket to rated
capacity.
6. Keep loaded bucket low to ground when transporting.
Always drive up and down slopes with load on the
uphill side. This will require backing down a slope to
keep load on the uphill side.
7.
To keep material from spilling over the back, tilt top of
bucket forward to maintain bucket levelness while
raising loader arms or traveling up a slope.
8. To keep material from spilling over the front, tilt top of
bucket back to maintain bucket levelness while
lowering loader arms or traveling down a slope.
Digging With The Bucket
The bucket can be used for digging in the ground or into
piles of dirt, sand, and other similar materials.
1.
Make sure load does not exceed rated lift capacity of
the skid steer.
2. Center skid steer on the material to be picked up.
3. Do not ram bucket into the ground or pile. Make a
complete stop in front of the material to position
bucket at the proper height and angle for digging.
If digging into the ground:
a. Lower loader arms until bucket is on the ground.
b. Tilt front of bucket down until cutting edge is on the
ground.
c. Start driving forward slowly while continuing to tilt
the edge down until bucket starts to dig.
d. Once the bucket starts digging, the front cutting
edge can be tilted up slightly to increase skid steer
traction and achieve even digging depth.
e. When digging hard ground, slowly raise and lower
the cutting edge while slowly traveling forward.
If digging into a pile:
a. Lower loader arms until bucket is on the ground.
b. Tilt front of bucket down until cutting edge is on the
ground.

Section 3: Operating Procedures
c. Start driving slowly into the pile. As the bucket
begins to fill, slowly raise loader arms until bucket
if filled to rated capacity.
4. With bucket filled, stop and raise the bucket out of the
pile. At the same time, tilt top of bucket back to keep
from spilling material out of the bucket.
5. Make sure bucket and load clears all obstacles when
making a “skid” turn or backing away.
6. Position load at a safe, low height and top of bucket
tilted slightly back to transport to the dump site.
Picking Up A Load With The Jaws/Clamshell
1.
Make sure load does not exceed rated lift capacity of
the skid steer being used to lift the load.
2. Center skid steer on the material to be picked up.
3. Make a complete stop in front of the material and
position bucket at the proper height.
4. Fully open the jaw and drive forward until the bucket
is above the pile. Do not ram bucket into the pile.
5. Lower bucket onto the pile and close the jaw to
secure the load.
6. Lift load a few inches to make sure you have good
control of the load. If load is not secure, release and
recapture load in a more secure location.
7.
12. Transport on public roadways without a load and
transport in such a way that faster moving vehicles
may pass you safely.
13. Plan your route to avoid heavy traffic.
Releasing A Load
1.
Stop in front of desired location and slowly raise load
to the required height for dumping.
2. Move slowly forward while checking to make sure
bucket and load clears all obstacles.
3. Stop forward movement when load is positioned over
its release location.
4. Releasing the load requires a combination of tilting
the front of bucket down or opening the jaw, and
raising the loader arms. The order in which the load
is released will vary depending on type of material
being released. The most important objective is to
have the load under control throughout the release.
5. Once the load has settled onto the pile, tilt bucket
level and close the jaw if opened.
6. Slowly back up making sure the bucket clears all
objects and no pedestrians or other traffic are behind
or on either side of skid steer.
7.
Lift load above the pile and then back load out of the
pile slowly, making sure load clears all obstacles.
As you back away, leave enough clearance when
turning and/or lowering the bucket so that it does not
make contact with obstacles such as vehicles,
buildings, trees, fences, etc.
8. Not always will the load be secured properly in the
bucket when pulled free from a pile. Before traveling
with a loose load, lower load to ground, release load,
and re-clamp load to make it more secure.
8. When clear of the pile, stop and lower bucket to

General Operating Instructions
Combination Bucket. If you haven’t, please do so now.
We cannot overstress the importance of following the
safety information and operating procedures that are
spelled out in this Operator’s Manual.
Proceed by getting onto the seat of your skid steer and
starting it up. It isn’t going to take you long to learn how to
use your new Kubota 4-in-1 Combination Bucket, but we
do recommend that you take a little time to practice
securely attaching and detaching your bucket to and from
your mounting plate. It is also important to practice lifting,
lowering, tilting, maneuvering, and releasing a load until
you gain the confidence and skill needed to have a good
feel in what you are doing.
If attachment is to be operated in reverse, make sure
visibility to the rear of the power unit is appropriate for the
attachment. Backup camera or mirror is recommended.
Maintain cleanliness of lens or mirror.
The 4-in-1 Combination Bucket’s primary purposes are
digging, loading, dumping, scraping, leveling, gripping,
and dozing. The following are some basic general
operating instructions. For detailed instructions, see
“Combination Bucket Operation” on page 16.
Start digging by lowering the bucket to the ground and
tilting the front cutting edge down to dig into the ground.
Start traveling forward making adjustments to the bucket
tilt and loader arm height to achieve desired results.
To dig while backing up, open the jaw, tilt the top of the
hitch plate forward, and lower the loader arms down until
the jaw’s cutting edge is on the ground. Start traveling
backward to fill the jaw with material and close the jaw to
capture the material in the bucket.
With bucket full, transport to your unloading site while
carrying the load low. Carefully place the load over the
dump site and dump the load by tilting the front bucket
down or by opening the jaw to release the load out the
bottom of the clamshell.
To scrape a surface clean and level, open the jaw, tilt the
top of the hitch plate forward, and lower loader arms until
the jaw’s cutting edge is on the ground. Begin backing up
and adjusting hitch plate tilt to achieve desired scraping
action. Lower or raise loader arms to achieve desired
cutting depth. You can close the jaw when you want to
capture and remove unwanted scraped material.
To pick up unwanted bulky material, open jaw, tilt top of
the hitch plate forward, and lower clamshell opening over
the material. Close jaw and pick-up load. Carry load low
to your discharge site. Carefully place load over the site
and dump load by opening the jaw.
To use the dozer blade, open the jaw, lower the dozer
blade to ground, and tilt top of hitch plate to angle the
blade for digging. Start traveling forward pushing the
material. Raise or lower the loader arms to adjust depth
of cut and adjust hitch plate tilt as needed to achieve
desired cutting action. You can close the jaw when you
want to capture and remove unwanted material.
With a little practice you should become very good at
consistently achieving the desired results you expect with
your Kubota 4-in-1 Combination Bucket.
See “Specifications & Capacities” on page 23 and
“Features & Benefits” on page 24 of your Operator’s
Manual for additional information.
By now you should have familiarized yourself with the
Operator’s Manual for your CB25 Series 4-in-1

Maintenance
Skid Steer Maintenance
Proper servicing and adjustment are key to the long life of
any equipment. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
One of the most important things you can do to prevent
hydraulic system problems is to ensure your hydraulic
reservoir remains free of dirt and contamination.
Check all bolts and pins after using the bucket for several
hours and on a regular basis thereafter to ensure they are
tight and secured.
Use a clean cloth to wipe hose ends before attaching
them to your skid steer. Replace your skid steer’s
hydraulic filter element at the prescribed intervals. These
simple maintenances will go a long way to prevent
occurrence of control valve and hydraulic cylinder
problems.
Check hitch plate fit-up, hydraulic hoses, and hydraulic
fittings on a regular basis to ensure trash or other objects
have not loosened hitch connection points and/or
damaged hydraulic hoses and fittings.
Replace worn, damaged, or missing bucket parts only
with genuine Kubota parts. Replace safety labels by
obtaining new labels from your Kubota dealer.
! DANGER
To avoid serious injury or death:
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment supported
by concrete blocks or hydraulics. Concrete can break,
hydraulic lines can burst, and/or hydraulic controls can be
actuated even when power to hydraulics is off.
! WARNING
To avoid serious injury or death:
• Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
Replace parts only with genuine OEM parts.
•
Check hitch fit-up frequently. An improper fit-up can cause
the attachment to come loose from the loader hitch plate
and fall.
•
Allow only persons to perform maintenance on this
attachment who have been properly trained in its safe
operation.
•
Check hydraulic hoses and fittings frequently for leaks or
damage. Fluid escaping under pressure can penetrate skin.
Large leaks can dump a load prematurely.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service.
•
Keep body, body extremities, loose clothing, pull strings,
etc. away from pinch points such as rotating, extending,
and/or retracting components. Secure pinch point areas to
ensure they will not move before working on or near them.
