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.

Introduction
Introduction
Kubota welcomes you to the growing family of new
product owners. This Excavator Auger has been
designed with care and built by skilled workers using
quality materials. Proper assembly, maintenance, and
safe operating practices will help you get years of
satisfactory use from this attachment.
Application
IMPORTANT: A special point of information related
to the following topic. Kubota’s intention is this
information must be read & noted before continuing.
Owner Assistance
The dealer should complete the Online Warranty
Registration at the time of purchase. This information is
necessary to provide you with quality customer service.
Kubota offers a complete line of augers designed to meet
a wide range of customer needs and applications. Our
hydraulically driven EA20 auger with a planetary gearbox
can accommodate augers ranging from 6" to 36" in
diameter. They include an auger mount for attaching to a
Kubota excavator with a mechanical quick coupler on the
end of the arm (dipper stick). The EA20 features
3 motor options to accommodate hydraulic flow systems
ranging from 6 to 30 gpm.
Serial Number
This auger is designed to deliver up to 2,621 ft-lbs of
torque to meet the heavy-duty needs of nurseries,
landscapers, contractors, construction companies,
farmers, ranchers, and municipalities. No matter what
your post hole digging needs are, Kubota has a model to
meet those needs.
For quick reference and prompt service, record model
and serial number on the inside cover page and again on
the warranty page. Always provide model number and
serial number when ordering parts and in all
correspondences with your Kubota dealer. For location of
your serial number plate, see Figure 1.
The EA20 is available with different mounts making it
capable of attaching to many Kubota excavators with a
mechanical quick coupler. With this machine, you can
improve digging performance in heavy, hardened soil by
applying additional down pressure with the excavator
boom. Should the auger jam in the hole and cannot,
under normal operating conditions, be raised, you can
reverse its rotation to back the auger out of the jam.
The parts on your Excavator auger have been specially
designed by Kubota/Land Pride and should only be
replaced with genuine Kubota parts. Contact a Kubota
dealer if customer service or repair parts are required.
Your Kubota dealer has trained personnel, repair parts,
and equipment needed to service the attachment.

attachment. Do not allow anyone to stand between
attachment and power machine while approaching or
backing away from the attachment. Do not operate controls
including lift, extend, and swing while someone is near the
power machine and/or attachment.
10. Insert linchpin (#4) in alignment pin (#5) and rotate
retainer loop over end of alignment pin.
•
Make sure the attachment is properly hooked to the
excavator. An improperly connected attachment can fall or
be thrown from the excavator.
•
Ensure the interior of the quick coupler housing is free of
obstructions and debris such as mud, excess dirt, rocks and
ice. Coupler engagement and disengagement may be
impeded and could potentially create an unsafe condition if
coupler is obstructed.
To avoid serious injury or death:
• 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.
•
Never stand beneath or position any body part beneath an
attachment that is being removed or installed.
•
Never attempt to shift an attachment that is raised off the
ground. A crushing and/or pinch point hazard exists
between coupler and attachment. Keep hands and fingers
clear.

•
This attachment has a 3500 psi maximum hydraulic
pressure rating. Make sure your powered machine’s
hydraulic pressure to this attachment does not exceed 3500
psi. Exceeding this rating can result in equipment damage,
serious injury, or death.
•
Do not install a bolt that is longer than what was originally
supplied with the auger. Protruding hardware is more likely
to entangle a bystander by catching on loose clothing.
•
Make sure the attachment is properly hooked to the
excavator. The quick coupler must be secured in the
attachment’s mount and coupler lock pin must be fully
inserted and secured with the linchpin. An attachment that
is improperly hooked can fall or be thrown from the coupler.
•
Keep all persons away from the attachment while lowering
and raising the unit. A person can be hit, pinched, or
crushed by the unit.
•
Keep others away from the auger while the unit is rotating.
A person can become entangled in the auger or be hit by the
auger if it swings erratically. Anyone helping should be kept
a safe distance (a minimum of 10 feet) from the auger while
it is rotating.
•
Care should always be taken when first starting to drill a
hole. The auger, when first entering the soil, can hit a solid
object causing damage to the auger and/or auger to swing
erratically and hit a bystander.
•
Do not allow anyone to manually push down on the
attachment, or put anything or anyone on the unit for the
purpose of adding weight to the unit. Objects and people
can be thrown, pinched, or entangled in the unit.
•
Protect freshly dug holes immediately after digging by
filling it with a post, covering the hole with a cover capable
of supporting a person, or place a physical boundary
around the hole to stop entry into the area.
•
Always travel with adequate clearance between ground and
auger. Hitting an object while traveling can damage
equipment and cause operator to lose control.
•
Always transport loads low to the ground to maintain
stability of the skid steer/tractor.
•
Make sure the boom and arm do not make contact with
buildings, fences, poles, trees, etc, or bystanders while
swinging the cab and/or boom from side to side. Hitting
property can damage the excavator and/or property. Hitting
bystanders can cause serious injuries or death.
•
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 to pull and/or pry fence posts,
stumps, roots, rocks, or other objects out of the ground. It is
not properly designed or guarded for this use.
•
Do not use attachment to wrap wire or any other items.
Doing so can result in bodily injury and/or damage to
equipment.
•
Never work near utilities such as gas lines, electrical lines,
or other hazards that can cause serious injury or death from
electrocution, explosion, or fire.
7/15/19
•
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,
or fire. If in doubt, call 811 (USA) before digging so that
they can mark the location of underground services in the
area. For contact information, see Dig Safe in the
“Important Safety Information” starting on page 1.
•
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:
Auger tip gets hot after digging. Allow time for the tip to cool
before touching or servicing the tip.
Dual-Angle Teeth
Refer to Figure 2-1 & Figure 2-2:
The Auger is shipped with teeth mounted at 40 degrees
(see Figure 2-1). If you are experiencing difficulty in
penetrating the soil, they can be turned over and
mounted at 50 degrees (see Figure 2-2) for a more
aggressive bite. Be sure to tighten all mounting hardware
to the proper torque when securing teeth to the Auger.
See “Torque Values Chart for Common Bolt Sizes” on
page 39 for torque ratings.

Transport With Auger Attached
! WARNING
To avoid serious injury or death:
• Swing cab to align the boom straight with direction of
travel. Should the auger hit a solid object while carrying the
auger with boom rotated left or right can damage the auger
and excavator and cause operator to lose control.
•
Cross ditches and enter inclines slowly and carefully. The
auger can come in contact with the ground causing damage
to the equipment and operator to lose control.
•
Always travel straight up and straight down inclines. Never
make turns on the incline.
•
Slow down when traveling over rough or hilly terrain that
can cause equipment to bounce, or to hit obstacles that are
close by. Either situation can cause damage and/or the
operator to lose control.
•
•
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.
Make sure the auger does not block the operator’s vision
while driving the excavator. Poor vision can cause the
operator to hit unseen objects and lose control of the
excavator.
IMPORTANT: Protect gearbox from damage while
transporting.
IMPORTANT: Transport excavator with auger curled
back and carried low to provide overhead clearances
when auger bit is bolted to the gearbox and has a
cradle for support.
IMPORTANT: Transport excavator short distances
with auger bit hanging straight down and close to the
ground when auger does not have a cradle or does
have an extension. Curling auger back in this
situation can damage the gearbox and/or auger
extension due to bouncing.
IMPORTANT: Transport excavator long distances
with auger unhooked and boom carried low when
auger does not have a cradle or does have an
extension. Curling auger back in this situation can
damage the gearbox and/or auger extension due to
shock loads caused by bouncing.
IMPORTANT: Transport with excavator on a trailer
and auger bit resting horizontally on the trailer bed.
This arrangement provides the lowest overhead
clearance and protects the gearbox from damage
due to shock loads caused by bouncing.

2. Transport with auger curled back and supported by
the optional cradle. Lower boom to carry the auger
low to the ground. If auger does not have a cradle,
carry auger hanging straight down with boom
lowered to carry auger point close to the ground.
3. Make sure your view is not blocked while traveling. If
necessary adjust boom height to improve your view.
4. Always travel straight up and straight down inclines.
Make turns only on level ground.
5. Enter ditches and inclines slowly to make sure the
auger does not dig into the ground. Stop and raise
auger if needed to cross a ditch or start up an incline.
6. Reduce ground speed when turning. Leave enough
room to clear obstacles such as buildings, trees, and
fences.
7.
Keep away from electrical power lines. Place an
orange warning sign under overhead power lines
indicating type of danger above.
8. When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
9. Reduce transport speed when traveling over rough
or hilly terrain.
Operating Instructions
! WARNING
To avoid serious injury or death:
• Auger point should be on the ground before engaging
hydraulics to start drilling. An auger not resting on the
ground can swing erratically and damage equipment or hit
a bystander.
•
Care should always be taken when first starting to drill a
hole. The auger, when first entering the soil, can hit a solid
object causing damage to the auger and/or auger to swing
erratically and hit a bystander.
•
Do not accidentally or intentionally move excavator
forward or backward, or rotate boom or cab while digging.
The auger and/or excavator can be damaged. Bystanders
can be seriously injured or killed.
•
Always stop auger from rotating 1 to 2 feet before it is out
of the hole. This will keep the auger from wobbling with an
unbalanced dirt load.
•
Operate only one hydraulic function at a time. Operating
two or more functions at a time can cause damage to the
equipment and/or operator to lose control.
IMPORTANT: Do not reverse auger rotation when
raising it up. This will dump soil back into the hole.
IMPORTANT: If auger stalls while digging, raise
auger to free it. Continue normal digging operations
by lowering the auger slowly into the hole.
IMPORTANT: If auger starts to screw itself into the
soil, stop auger rotation immediately and raise auger
to free it. Continue normal digging operations by
lowering the auger slowly into the hole.
7/15/19
Table of Contents
Section 2: Operating Procedures
IMPORTANT: If the auger has become jammed in
the hole, reverse its rotation to raise it easily. After
the auger is free, continue normal digging
operations by lowering the auger slowly in the hole.
70186
IMPORTANT: If the dirt auger bit can not penetrate
an obstruction, change auger head to the optional
rock auger head, switch auger bit to the optional rock
auger bit, or dig a new hole nearby. See “Options &
Accessory” Section in this manual for optional rock
auger heads and rock auger bits.
Keep motor/gearbox housing (#1)
away from optional cradle (#2)
while auger is operating.
IMPORTANT: Some power machines have a
hydraulic relief valve to protect the equipment. This
valve will open in a stalled situation to allow oil to
bypass. Check your power machine Operator’s
Manual to see if it is equipped with a relief valve.
IMPORTANT: Be careful to keep the auger bit
vertical throughout the dig. Damage to the unit and/
or power machine can occur if bending forces are
applied to the auger while digging a hole.
1.
Extend curl cylinder and lower auger low to the
ground while traveling between drilling positions.
Operating Position of Auger Hitch
Figure 2-3
37287
2. It is best to stop the excavator on a surface that is
level side to side or on an incline facing straight up or
straight down the incline. This will greatly improve
balance and down force while digging.
3. Experiment with auger speeds before digging.
Increase excavator engine speed to increase auger
speed and decrease engine speed to reduce auger
speed. Run at higher auger speeds when digging in
soft and/or sandy soils and at lower auger speeds
when digging in hard, rocky, or frozen soils. Normal
auger speed is 85 to 100 rpm. Never exceed 110 rpm
or the equipment can be damaged.
Refer to Figure 2-3:
IMPORTANT: Before digging, curl coupler
mount (#3) slightly back as shown in Figure 2-3. This
will put distance between motor/gearbox housing
(#1) and optional cradle (#2).
4. Raise the boom and retract curl cylinder until optional
cradle (#2) is safely away from motor/gearbox
housing (#1) as shown. If optional cradle (#2) is not
included, auger can be operated with coupler
mount (#3) horizontal.
5. With the boom facing straight forward, drive forward
or backward as needed to center auger point on the
hole to be drilled.
6. Make sure auger swinging has stopped and then
lower auger point to the ground while making sure
the point is centered on the hole to be drilled.
7.
Lower dozer blade to help keep excavator from
drifting.
8. Swivel boom left or right as needed to align the auger
vertically from left to right.
7/15/19
Vertical Indicator
Figure 2-4
9. Refer to Figure 2-4: Adjust arm in or out until vertical
indicator arrow (#1) points to the “Vertical Line”. This
aligns the auger vertically from front to back.
10. With engine running at a slow speed, start auger
turning clockwise. Increase engine speed to desired
digging speed.
11. Lower boom as auger penetrates into the ground.
Apply down pressure with the boom to assist ground
penetration. Excessive down pressure can cause the
hydraulic system to overheat and stall the auger. If
auger speed slows or stops, reduce down pressure.

Table of Contents
Section 2: Operating Procedures
12. Swivel boom left or right and arm forward or
backward as needed to keep the auger vertical while
digging.
Do not operate the auger with auger bit off the ground.
The auger could swing erratically causing injury to
operator, bystanders, and damage to equipment.
13. After penetrating the ground approximately 24", stop
auger rotation and raise it up to remove soil and
debris from the hole. Lower auger back into the hole
to continue digging. Dig another 24" down except this
time raise auger up with it still turning to lessen the
strain on the equipment. Stop raising auger within
1 to 2 feet of being out of the hole and lower it back
into the hole to continue digging. Repeat this
procedure until hole is at its final depth.
With engine at an idle, engage hydraulic drive circuit and
raise engine rpm to operate the auger at its rated
hydraulic flow. Auger should be turning clockwise at an
approximate speed of 85 to 100 rpm. Do not operate
auger above 110 rpm or damage to the auger and
excavator could result. Use the excavator boom to assist
driving the auger into the ground and to align the auger
vertically left to right while digging. Use the excavator arm
to align the auger vertically front to back while digging.
14. Allow auger to turn several revolutions at final depth.
With auger still turning, raise auger up to within 1 to 2
feet of being out of the hole. Stop auger rotation and
continue to raise auger out of the hole.
After penetrating the ground approximately 24", stop
auger rotation and raise auger up to remove soil and
debris from the hole. Lower auger back into the hole and
continue digging. Dig approximately another 24" down
except this time raise auger up with it turning to lessen
the strain on the equipment. Stop raising auger when
within 1 to 2 feet of being out of the hole and lower auger
back into the hole to continue digging. Repeat this
procedure until the hole is at its final depth. Allow auger to
turn several more revolutions at final depth. With auger
still turning, raise auger up to within 1 to 2 feet of being
out of the hole. Stop auger rotation and continue to raise
auger until it is out of the hole.
15. Curl auger back to carry auger low when transporting
from one digging site to the next. Be careful to watch
out for people, obstructions, and uneven terrain.
General Operation
By now you should have thoroughly read your Operator’s
Manual, properly attached your auger to your machine,
verified auger rotates clockwise when engaged, and
gone over the “Operating Checklist” on page 22. Be
sure to 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. If you have not done all of the things
just described above, please stop and do them now. This
is a must for your safety and the safety of others.
Now that you are properly briefed, your EA20 auger is
properly installed, and you have the proper digging
authorization from the utility companies; it is time for you
to transport to the work site. Make sure that the auger is
in its carrying position and does not make contact with
the ground. Select a safe traveling speed and transport
to your site in such a manner that faster moving vehicles
can pass you safely. If you are using a public road or
right-of-way, install a slow moving vehicle sign where it is
visible from the back. If towing the excavator on a trailer,
the sign should be covered or removed.
Once you have safely arrived at your digging site, you
should position your excavator so that the auger is
directly over the spot where you want to dig a hole.
Retract curl cylinder until optional cradle is safely away
from the motor/gearbox housing. If cradle is not included,
retract curl cylinder until coupler is approximately level.
Lowering auger until auger point is resting on the ground
centered over the planned hole. Lower dozer blade to
keep excavator from moving. Swivel boom left or right to
align the auger vertically from left to right, and rotate arm
forward or backward to align the auger vertically from
front to back.
26
AP-EA20 Excavator Auger 317-252MK
Periodically adjust boom and arm positions to keep auger
vertical while digging the hole. Use vertical indicator on
the gearbox to maintain vertical alignment from front to
back. Be careful not to damage the gearbox or auger.
Apply down pressure with the boom to assist ground
penetration. If auger speed slows or stops, reduce down
pressure. Excessive down pressure can over heat
hydraulics and stall the auger. Stop auger rotation
immediately if an obstacle is encountered that stalls the
auger. Reverse auger rotation and lift up to clear the
obstacle.
Once the hole is completed, disengage hydraulic drive,
raise and curl auger back until it is approximately 12" off
the ground, raise dozer blade and move away from the
hole.
You should park on a solid, flat, and level surface, lower
the boom until the auger mount is resting on the ground,
lower dozer blade to the ground, reduce engine speed,
remove switch key, and lock control levers before
dismounting the excavator.
With a little practice and experience you should become
very good at operating your Kubota EA20 Excavator
Auger.

Section 4: Maintenance & Lubrication
Maintenance
Daily Inspections
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.
1.
Read and obey all safety labels on the auger. Securely
block raised equipment before working under or around
it. Do not allow anyone to operate or perform
maintenance on this attachment who has not been
properly trained in its safe operation. Do not alter
equipment in a way which will adversely affect its
performance or reliability, or for a purpose the product is
not designed.
2. Inspect auger flighting for wear, bend, and cracks.
! DANGER
To avoid serious injury or death:
• Always shut excavator down using “Excavator Shutdown
Procedure” on page 10 before dismounting the power
excavator and/or allowing anyone to come near the
excavator and attachment.
•
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.
•
All guards and shields must be installed and in good
working condition while operating the attachment.
! WARNING
To avoid serious injury or death:
• The hydraulic flow must be disengaged and engine shut off
before anyone is allowed to clean or service the attachment.
A person can become entangled or pinched in the rotating
auger.
•
•
Keep all persons away from the attachment while lowering
and raising the unit. A person can be hit, pinched, or
crushed by the unit.
Allow only persons to perform maintenance on this
attachment who have been properly trained in its safe
operation.
•
Always lower attachment and dozer blade to the ground,
shut engine off, remove switch key, and lock control levers
before dismounting the excavator.
•
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.
•
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service.
Make sure safety labels are installed in their proper
location and are in good condition before operating the
attachment. Read and obey all instructions on the labels.
7/15/19
Inspect auger point and teeth for wear and loose fit.
Keep cutting edges sharp. Sharp cutting edges dig
easier and better.
3. Inspect auger mounting hardware for wear, bend,
and loose fit.
4. Inspect all connecting pins and hardware for wear,
bend, and loose fit.
5. Inspect output shaft for bend and wear.
6. Check gearbox fluid level periodically. Refer to “Gear
Lube Fluid Level” on page 33 for detailed
instructions.
7.
Replace all worn, damaged, or illegible safety labels
by obtaining new labels from your Kubota dealer.
Long-Term Storage
Clean, inspect, service, and make necessary repairs to
the auger when storing it for long periods and when
storing it at the end of a working season. This will help
ensure the auger is ready for field use the next time you
hook-up to it.
1.
Clean dirt and grease that may have accumulated on
the unit. Scrape off compacted dirt and then wash
thoroughly with a garden hose.
2. Check auger flighting for wear, bend, and cracks and
repair or replace as needed.
3. Inspect auger for loose, damaged, or worn
components and adjust or replace as needed.
4. 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.

the hole.
1. Dozer blade was not lowered. Lower dozer
blade to help stop movement.
2. Brace crawlers with chocks to stop movement.
Excavator is sideways on an incline causing the
boom and arm to be at an angle to the hole.
1. Line excavator straight up or down an incline to
keep boom and arm in line with the hole.
2. Swivel boom left or right to keep auger aligned
vertical while digging.
Auger is not vertical with auger point resting on
the ground.
1. Extend or retract arm cylinder to align auger
vertical from front to back.
2. Swivel boom left or right to align auger vertical
from left to right.
Auger starts to angle as it digs deeper.
1. Extend or retract arm cylinder as needed to
keep auger aligned vertical from front to back.
2. Swivel boom left or right to keep auger aligned
vertical from left to right.
Auger is encountering rocks, roots, or other
obstructions.
