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

 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

4/4/19
 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.

Introduction
Introduction
Kubota welcomes you to the growing family of new
product owners. This Tree/Post Puller 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 product.
The parts on your Tree/Post Puller have been specially

dealer if customer service or repair parts are required.
Your Kubota dealer has trained personnel, repair parts,
and equipment needed to service the attachment.
Application
Serial Number
The Kubota STP15 Tree/Post Puller is designed and built
by Kubota to remove shrubs, saplings, and small trees;
pulling them from the ground, roots and all. The serrated
teeth also make this an ideal tool for removing steel and
wood fence posts. It has uses and applications in
farming, ranching, construction sites, nurseries,
orchards, landscaping, and fence building.
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.
37770
The 10" jaw opening allows you to grasp and pull a wide
range of trees and posts with the added benefit of
minimal ground disturbance. Because the roots are
removed with the tree, chances for regrowth are also
eliminated without the use of chemicals. When the jaws
are closed, the ends form a spade point for digging into
the ground to loosen the tree roots. Fittings and hydraulic
hoses are protected at the hydraulic cylinder with a
durable steel guard around the hydraulic cylinder.
See “Specifications & Capacities” on page 18 and
“Features & Benefits” on page 19 for additional
information and performance enhancing options.

Section 2: Operating Procedures
Operating Safety
•
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.
•
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.
•
Always use a skid steer with a polycarbonate cab door
when pulling, transporting, and releasing trees. Roots and
tree limbs can come into the cab.
•
Always position the jaws of the Tree/Post Puller near the
ground when grabbing on to a tree or post. Lift straight up
and don’t tilt backwards or forwards. This will help prevent
the tree or post from hitting the operators cab.
•
Check hitch fit-up frequently. An improper fit-up can cause
the attachment to come loose from the loader hitch plate
and fall.
•
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.
•
Do not use attachment as a lifting device for people or as a
work platform. It is not properly designed or guarded for
this use.
•
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 objects out of the
ground or for digging into the ground. It is not properly
designed or guarded for this use.
•
Do not use attachment to lift the front or back of the power
machine off the ground. Doing so can damage the
attachment, power machine, and/or cause serious injury or
death.
•
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.
! DANGER
To avoid serious injury or death:
• A Crushing hazards always exist around attachments. A
person can become pinched or crushed as the attachment is
rotated, raised, and/or lowered. Objects in the attachment
can shift and fall.
•
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.
•
Always reduce pulling forces once a tree or post starts to
pull loose from the ground. Large trees can require high
pulling forces that can cause the skid steer to quickly rock
back when the tree suddenly breaks loose from the ground
or if the jaws slip instantaneously on the tree or post.
•
Always be aware of a falling tree hazard. Any tree can fall
that has lost a part of its root support. Be especially
cautious of falling trees when pulling large trees.
•
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.
•
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 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.
•
Maximum lift capacity should never exceed the power
machine’s rated lift capacity. Exceeding rated capacity can
result in equipment damage or a roll over that can cause
injury or death.
! WARNING
To avoid serious injury or death:
• Allow only persons to operate this implement who have
fully read and comprehended this manual, who have been
properly trained in the safe operation of this implement, and
who are age 16 or older. Serious injury or death can result
from the inability to read, understand, and follow
instructions provided in this manual.
•
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.
•
Do not abuse equipment. Incorrect use of the attachment
can damage equipment structurally and cause serious
injury or death.
•
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.

Section 2: Operating Procedures
•
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.
•
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.
•
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.
IMPORTANT: Always close jaws against each other
before digging into the soil. Digging with jaws spread
apart can damage the frame, pivoting jaw, hydraulic
cylinder, and pivot pins.

AP-STP15 Tree/Post Puller 328-222MK
Transport Safety
! DANGER
To avoid serious injury or death:
• The operator of this attachment must know how to control
the power machine with attachment and how to stop them
quickly in an emergency.
•
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:
• 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.
•
Transport with load upright to help keep it from falling.
Never tilt load toward the operator.
•
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.
•
•
Never transport a load on roadways.
When traveling on public roads, use LED lights, slow
moving vehicle sign, clean reflectors, and other adequate
devices to warn operators in other vehicles of your
presence. If implement blocks visibility of slow moving
vehicle sign, relocate sign so it is visible from the back at all
times. Always comply with all federal, state, and local laws.

Section 2: Operating Procedures
General Operation
By now you should have familiarized yourself with the
Operator’s Manual for your STP15 Tree/Post Puller. 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.
The skid steer should have a door on its cab to operate
the Tree/Post Puller safely. It will help stop tree limbs and
roots from coming into the cab.
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
Tree/Post Puller, but we do recommend that you take a
little time to practice securely attaching and detaching
your Tree/Post Puller to and from your skid steer
mounting hitch plate. It is also important to practice
maneuvering the Tree/Post Puller by raising and lowering
the puller and tilting the hitch forward and backward until
you have gained the confidence and skill needed to have
a good feel in what you are doing.
If you have not already done so, have the site marked
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.
against this, ease off on the lift cylinders once the tree or
post starts to pull loose from the ground. At this time,
exert only enough force to slowly raise the post or tree
from the ground.
Some trees may require the roots to be excavated. Use
the spade points on the end of the jaws to do this. Always
close jaws tight against each other before digging into the
soil. Rotate top of skid steer hitch plate forward to angle
spades into the soil. Dig under the roots and rotate top of
skid steer hitch back and raise skid steer loader arms up
to rip individual roots from the ground. Continue to dig
around the base of the tree in this fashion until all major
roots have been ripped from the soil or broken into.
As conditions allow, several smaller trees can be
accumulated inside the jaws of the Tree/Post Puller
before disposing of them on a tree pile. Simple carry the
first tree pulled to the next tree, lower the Tree/Post Puller
down, and open its jaws to capture the next tree while
keeping the first tree still inside the jaws. Close jaws
around both trees and pull. Continue to capture other
small trees using this method until the jaws have exceed
their ability to hold more trees.
When ready, transport post(s) and/or tree(s) upright in
the jaws to the pile. At the pile, rotate top of skid steer
hitch plate forward to place the tree(s) or post(s) onto the
pile. Release the grip the jaws have on the post(s) or
tree(s).
It is now time to start removing those unwanted trees
and/or posts. The maximum size of tree or post that can
be pulled will vary depending on condition of the soil,
diameter and species of the tree, and size of the skid
steer pulling the tree or post. Pull only trees and posts
that are 10" and under in diameter.
Start by opening the jaws and lowering the puller close to
the ground. Move slowly forward to capture the tree
inside and to the back of the jaws. Close jaws against the
tree to drive the teeth into the tree. Be careful not to close
the jaws so tight as to shear off the tree or post.
Raise skid steer loader arms up to pull a post or tree out
of the ground. If assistance is needed, move forward and
backward while pulling. Some side to side movement
may also be applied to assist pulling.
Larger trees and posts that require higher forces can
suddenly break loose from the ground resulting in a
sudden uplift at the front of the skid steer. To guard

Maintenance
Skid Steer Maintenance
Proper servicing and adjustment are 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
hydraulic system remains free of dirt and contamination.
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 all bolts and pins after using the puller for several
hours and on a regular basis thereafter to ensure they are
tight and secured.
Check hitch fit-up, hydraulic hoses, and fittings on a
regular basis to ensure trash or other objects have not
loosened the hitch connection or damaged hydraulic
hoses and fittings.
Replace worn, damaged, or missing parts only with
genuine Kubota parts.
Replace illegible or missing safety labels by obtaining
new labels from your Kubota dealer.
Long-Term Storage
Clean, inspect, service, and make necessary repairs to
the attachment when storing it for long periods and at the
end of the season. This will help to ensure the unit is
ready for field use the next time you hook-up to it.
1.
! 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:
• Allow only persons to perform maintenance on this
attachment who have been properly trained in its safe
operation.
•
Check hitch fit-up frequently. An improper fit-up can cause
the attachment to come loose from the loader hitch plate
and fall.
