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
work. Refer to the Operator’s Manual
for additional information.
 Work on a level surface in a clean
dry area that is well-lit.
 Lower attachment to the ground and
follow all shutdown procedures
before leaving the operator’s seat to
perform maintenance.
 Do not work under any hydraulic
supported equipment. It can settle,
suddenly leak down, or be lowered
accidentally. If it is necessary to work
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
while it is in operation.
 Remove buildup of grease, oil, or
debris.
 Always make sure any material and
waste products from the repair and
maintenance of the attachment are
properly collected and disposed.
 Remove all tools and unused parts
from the equipment before
operation.
11/13/19
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
fringes and pull strings to avoid
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
this type of injury immediately.
Any fluid injected into the skin or
eyes must be treated
within a few hours or
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.
11/13/19
 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 can be a serious
health hazard.
 Store or dispose of unused
chemicals as specified by the
chemical manufacturer.

watch it while it is working. Not having good visibility of
your work area can cause a serious injury or death.
• Always operate skid steer while seated in the cab with seat
bar lowered when equipped and seat belt properly fastened.
The operator can be pinched, crushed, or thrown if not
properly seated in the cab or if operating loader arms from
outside the cab.
• 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.
• 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.
• A crushing hazard that can cause serious injury or death
always exists around power equipment.
• 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.
• 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:
• Never make contact with underground utilities such as
electrical power lines, gas lines, phone lines, etc. They can
cause serious injury or death from electrocution, explosion,

Use Stump Grinder for grinding tree stumps only. Do not
use as a ditcher or for any other purpose. The attachment
can come in contact with underground utilities, rock, and
other debris that can damage the cutting wheel/skid steer
and cause serious injury or death.
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.
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.
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.
Do not travel across inclines where equipment could slip or
roll-over. Consult your power machine Operator’s Manual
for acceptable inclines they are capable of crossing.
Do not use Stump Grinder to remove material other than
wood. Doing so can cause components to break, solid
objects to be thrown, and breakdowns. Any of these
problems can cause serious injury or death.
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.
Never carry riders on the attachment or power machine.
Riders can obstruct the operator’s view, interfere with
controls, be pinched by moving components, become
entangled in rotating components, struck by objects, thrown
about, fall off and be run over, etc.
Do not abuse equipment. Incorrect use of skid steer and
Stump Grinder can damage equipment structurally and
cause serious injury or death.
Check hook-up points frequently to make sure skid steer
hitch is properly positioned under the top angle bar, locking
pins are seated in their notches, handles are locked down,
and equipment is in good operating condition.
Do not carry or lift loads with the Stump Grinder.
Do not use Stump Grinder as a working platform. Using
grinder as a working platform can cause serious injury or
death.
Do not use Stump Grinder for lifting front end of skid steer
off the ground. Doing so can damage equipment and cause
injury if exceeding lift capacity of unit.

•
Do not use Stump Grinder for pulling objects out of the
ground, for digging into the ground, for prying other
objects, or for pushing and towing other equipment.
The parts on your Stump Grinder have been specially
designed and should only be replaced with genuine Kubota
parts. Altering the grinder can adversely affect its
performance and/or reliability.
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.
! CAUTION
To avoid minor or moderate injury:
• Failure to obey all safety instructions listed below can
result in injury to the operator and other personnel.
• Always lower Stump Grinder to ground level before
dismounting skid steer.
• Always store Stump Grinder in a secure position so that it
will not fall over.
• Follow all recommendations provided by the skid steer
manufacturer when adding counter weights and other
ballast.
• Follow manufacturer’s recommendations when
dismounting and parking the skid steer.
• Do not exceed Stump Grinder specifications for maximum
input power and/or cutting wheel speed. Personal injury
and/or equipment damage can occur.
Transport Safety
! 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 travel straight up and straight down inclines. Never
make turns on the incline.
• 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 roadways, travel in such a way that
other vehicles may pass you safely. Use LED 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.

Section 3: Operating Procedures
General Operating Instructions
By now you should have familiarized yourself with the
Operator’s Manual for your model SSG2524 Stump
Grinder. If you have not done so, please do so now.
We cannot overstress the importance of reading and
following the safety information and operating
procedures that are spelled out in this Manual.
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.
Proceed by getting into the seat of your skid steer and
fastening your seat belt before starting your skid steer. It
won’t take you long to learn how to use your new Kubota
Stump Grinder, but we do recommend that you take a
little time to practice securely attaching and detaching
your Stump Grinder to and from your mounting hitch
plate. It is also important to practice maneuvering,
lowering, rotating the hitch plate, tilting the cutting wheel
up and down, and articulating the cutting wheel left and
right until you have gained the confidence and skill
needed to have a good feel in what you are doing.
It is now time for you to make a running operational
check. Make certain that the skid steer’s park brake is
engaged and auxiliary hydraulics are disengaged. You
should now start the engine and lower the hitch plate until
the skid shoes are fully seated on the ground. Next,
rotate the top of the hitch plate back to lift the cutting
wheel off the ground, back off the engine rpm to
approximately one-quarter the throttle speed, and then
engage auxiliary hydraulics. Never engage auxiliary
hydraulics at full engine rpm. Damage to the Stump
Grinder can occur. As you engage the hydraulics, you
should be watching the direction the cutting wheel turns.
The bottom of the wheel should rotate away from the skid
steer. If the bottom of the cutting wheel is rotating towards
the skid steer, then you should disengage auxiliary
hydraulics and shut off the engine. You will need to switch
the quick disconnect couplings on the hydraulic hoses to
correct this situation. Once the couplings are switched,
reattach hydraulic hoses to the skid steer and return to
the skid steer seat to recheck rotational directional of the
cutting wheel. Increase throttle speed if everything is
running properly and smoothly until you have reached full
operating speed.
Next you should extend and retract the articulation
cylinder to move the cutting wheel left to right and right to
left. Also extend and retract the tilt cylinder to raise and
lower the cutting wheel. If either one of the hydraulic
cylinders are operating opposite of what is expected,
slow the engine to an idle, disengage auxiliary
hydraulics, make sure loader arms are all the way down,
and shut the engine off. You will need to switch electrical
connections at the skid steer solenoids to correct the
problem. Switch only the electrical connections that
operated the hydraulic cylinder in the opposite direction
intended. Return to the loader and recheck the cylinder
or cylinders in question.
It is now time to start removing those unwanted stumps.
If you have not already done so, have the site marked
11/13/19
with flags to indicate where underground utilities run.
Also check for overhead obstructions and place orange
warning signs under overhead electrical power lines
indicating type of danger above.
Before approaching the stump, fully retract the tilt
cylinder and move the cutting wheel left or right until it is
centered in front of the skid steer. With skid steer engine
at an idle, continue to approach the stump. You will want
to rotate the top of the hitch plate back to clear the stump
as the cutting wheel passes over it and you should stop
moving forward once the cutting wheel is positioned on
the far side of the stump. Once stopped, set park brake,
lower hitch plate down until skid shoes are firmly planted
on the ground, and then rotate top of hitch plate forward
until the cutting wheel is just above the stump. It is time to
raise the engine rpm to full operating speed, extend the
articulate cylinder to move the cutting wheel fully to the
right, and extend the tilt cylinder until the cutting teeth are
below the top of the stump.
You are now ready to begin chipping away at the stump.
Slowly retract the articulation cylinder to move the cutting
wheel to the left as it removes pieces of wood from the top
of the stump. Once the cutting wheel has passed across
the top of the stump, lower the cutting wheel again and
begin moving the cutting wheel back across the stump. At
the end of each pass across the stump, lower the cutting
wheel and make another pass back across the stump
until a layer of approximately 4" deep has been removed
and/or you are ready to back-up to a new cutting position
over the stump.
Before backing-up, you should fully retract tilt cylinder,
move cutting wheel left or right until centered over the
stump, raise loader arms up several inches, lower engine
speed to an idle, release park brake, and then back skid
steer up to a new location over the stump. After you have
stopped moving, you should lower the hitch plate down
until it is resting on its skid shoes and reset the park
brake. With park brake set, raise engine speed to full
operating speed and move cutting wheel to the right side
of the stump. Begin chipping away at the stump as before
until approximately 4 more inches have been removed
across the top of the stump. You should repeat this
process of cutting down the top of the stump and backing
up until the first layer, approximately 4" deep, has been
completely removed from far side to near side of stump.
Once the top layer has been completely removed, retract
tilt cylinder, raise hitch plate up several inches, return
engine to an idle, and move forward to the far side of the
stump to begin removing a second 4" deep layer of wood.
After the second layer has been completely removed, the
skid steer should once again be repositioned to the far
side of the stump to continue to remove another layer and
another until the stump has been completely removed
below the ground up to a maximum depth of 8".
With a little practice, you will find that you will quickly
become very adept, handy, and skillful at using your
Kubota SSB2524 Stump Grinder.

“Features & Benefits” on page 20 of your Operator’s

Maintenance
Skid Steer Maintenance
Proper servicing and adjustment are key to the long life of
any attachment. 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 skid steer
reservoir remains free of dirt and contamination.
Check all bolts and pins after using the grinder 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 fit-up, hydraulic hoses, hydraulic fittings, and
wiring harness on a regular basis to ensure trash or other
objects have not loosened hitch connection or damaged
hydraulic hoses, fittings, and wiring harness.
Replace worn, damaged, or missing Stump Grinder parts
only with genuine Kubota parts.
Replace illegible or missing safety labels by obtaining
new labels from your Kubota dealer.
! DANGER
To avoid serious injury or death:
• Do not go near or under raised loader arms without first
securing loader arms in the raised position with an
approved lift-arm support.
• 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:
• Always shut power machine down using the “Shutdown
Procedure” provided in this manual before servicing,
adjusting, cleaning, or maintaining the attachment.
• Check hitch fit-up frequently. An improper fit-up can cause
the attachment to come loose from the loader hitch plate
and fall.
• Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting the
implement back into service.
• Do not alter attachment or replace parts on the attachment
with other brands. Other brands may not fit properly or
meet OEM specifications. They can weaken the integrity
and impair the safety, function, performance, and life of the
attachment. Replace parts only with genuine OEM parts.
• 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.

Cutting Wheel Maintenance
NOTE: “Right-hand” and “left-hand” designation for
the carbide teeth are determined by standing in front
of the Stump Grinder while facing the skid steer.
IMPORTANT: Make certain the teeth are mounted
with carbide cutting tip leading in rotation. Mounting
a tooth backwards can cause the carbide tip to pull
loose and damage the tooth.
Refer to Figure 5-1 on page 32:
The cutting wheel has 32 carbide cutting teeth. Eight are
straight teeth (#4), twelve are left-hand bent teeth (#2),
and twelve are right-hand bent teeth (#3).
IMPORTANT:
Carbide Cutting Edge Must Lead In Rotation.
Straight teeth (#4) are attached only to the outer bolt
circle diameter. Always attach one straight tooth and
one bent tooth in pairs. Alternate straight teeth from
side to side when attaching them.
The right-hand teeth (#2) are attached to the cutting
wheel on the far side (FS) in series of three between
the straight teeth.
The left-hand teeth (#3) are attached to the cutting
wheel on the near side (NS) in series of three
between the straight teeth.
Refer to Figure 5-3 on page 32:
1. Remove hex flange locknuts (#3) and shroud (#2)
from cutting wheel (#1).
Refer to Figure 5-2 on page 32:
2. Hold tapped block (#6) against cutting wheel (#1)
while loosening the two hex socket cap screws (#7)
until right-hand tooth (#2) can be removed.
3. Remove and replace right-hand tooth (#2) with a new
or resharpened right-hand tooth.
4. Hold counterbore block (#5) against cutting
wheel (#1) and remove left-hand tooth (#3).
5. Replace left-hand tooth (#3) with a new or
resharpened left-hand tooth.
6. Tighten hex socket cap screws (#7) to the torque
value provided under “Additional Torque Values” on
page 37.
7. Repeat steps 2 to 6 to replace the remaining
right-hand, left-hand, and straight teeth.

Long-Term Storage
Clean, inspect, service, and make necessary repairs to
the implement when storing it for long periods and at the
end of the season. This will help ensure the unit is ready
for field use the next time you hook-up to it.
1.
Clean off any dirt and grease that may have
accumulated on the Stump Grinder. Scrape off
compacted dirt and then wash its surface thoroughly
with a garden hose.
2. Inspect Stump Grinder for loose, damaged, or worn
parts and adjust or replace when needed.
3. Repaint parts where paint is worn or scratched to
prevent rust. Ask your Kubota dealer for touch-up
paint. Paint is available in aerosol can, quarts, and
gallon sizes. See chart below.
