steep inclines with heavy end of skid
steer on the “uphill” side.
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.
Dig Safe - Avoid
Underground Utilities
USA: Call 811
CAN: digsafecanada.ca
Always contact your local utility
companies (electrical, telephone,
gas, water, sewer, and others)

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.
Wear
Protective Equipment
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.
Use Safety
Lights and Devices
Slow moving tractors, skid steers,
self-propelled machines, and
towed equipment can create a
hazard when driven on public
roads. They are difficult to see,
especially at night. Use the Slow
Moving Vehicle sign (SMV) when
on public roads.
Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
Keep Riders Off
Machinery
Never carry riders or use the
machinery to lift or transport
individuals.
There is not a safe place for a
person to ride.
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.
Use Seat Belt and ROPS
Kubota recommends the use of a
CAB or roll-over-protective-
structures (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.

Hydraulic Hose Hook-ups
!DANGER
To prevent serious injury or death:
Hydraulic fluid under high pressure will penetrate skin. 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. If hydraulic fluid
is injected into the skin or eyes, it must be treated by a doctor
familiar with this type of injury within a few hours or gangrene
may result. DO NOT DELAY.
Refer to Figure 1-6:
1. Route hydraulic hoses (#7, #8, & #9) along the most
convenient path to access your skid steer couplings
and sump.
2. Clean quick connect couplers of dirt and then connect
hoses (#7 & #8) to the skid steer couplers.
3. Make sure quick connect couplers have fully engaged.
If not, check couplers to see if they are same size and
type. Also, make sure all hydraulic pressure to the
couplers has been released.
4. Connect case drain line (#9) to sump as follows:
a. If case drain line is fitted with a coupler, connect
case drain line to the sump coupler.
b. If case drain line is not fitted with a coupler:
•Wrap Teflon tape around 3/8" MNPT threads on
end of case drain line.
•Screw any customer supplied fittings to case
drain line (#9) and to sump port until tight.
IMPORTANT: Collect and dispose all oil spills and
leaks in an environmentally safe manner.
IMPORTANT: Hose routing is the responsibility of
the owner/operator of the tiller. Pinched and/or
stretched hoses are not covered under the warranty.
IMPORTANT: Make sure all coupler fittings are
clean before connecting them together.
NOTE: If attaching to a Kubota compact track loader
or skid steer loader, route hydraulic hoses as shown
in Figure 1-7. Be sure to thread hoses through
spring hose loop (#2). Do not use Kubota’s SVL or
SSV Hose Stay.
Skid Steer Primary & Secondary
Ports
Refer to Figure 1-6:
Hydraulic flow and pressure from the skid steer primary
and secondary ports may vary. The primary port usually
delivers more power than the secondary port. This
means the bi-directional tines will have more power when
driven by the primary port. If operator prefers to mainly
turn tines in one direction, then couplings (#3 & #4)
should be attached to the hydraulic hoses so that the
primary port on the skid steer is driving the tines in that
direction. Consult your skid steer Operator’s Manual to
know which port is the primary port.

Shank Settings
The shanks can only be used with pointer on depth
indicator pointing at the 2" and 4" depths above “FULL
DEPTH”. Set shanks to dig in the ground as follows:
Shank Settings When Tilling Full Depth
Refer to Figure 2-8:
The shanks cannot be used when pointer on depth
indicator is pointing at “FULL DEPTH”. The same is true if
the pointer is pointing to 4" or 2" depths below “FULL
DEPTH”. The shanks are not long enough to penetrate
the ground at these settings.
Shanks Settings When Tilling 4" Deep
Refer to Figure 2-9:
With tiller rotated back and pointer on depth indicator
pointing at the 4" depth above “FULL DEPTH”, the
shanks will penetrate the ground 4 7/8" when set in the
first notch, 3 1/8" when set in the second notch, and
1 3/8" when set in the third notch.
The skid steer can travel forward or backward when tiller
is rotated back or forward to till 4" deep.
Shanks Settings When Tilling 2" Deep
Refer to Figure 2-10:
With tiller rotated back and pointer on depth indicator
pointing at the 2" depth above “FULL DEPTH”, the
shanks will penetrate the ground 5 3/4" when set in the
third notch, 4 1/8" when set in the second notch, and
2 3/8" when set in the first notch.
The skid steer should only travel forward when tiller is
rotated back to till 2" deep. If one was to travel backwards
while tilling, the skid shoes would dig into the ground.
NOTE: The shanks can be operated at a different
depth than noted below by raising the tiller off the
ground with the loader arms. This will also change
how deep the tiller is running. Know that the depth
indicator will not give an accurate reading with skid
