THIS SYMBOL IDENTIFIES IMPOR-
TANT SAFETY MESSAGES. WHEN YOU SEE
IT, READ THE MESSAGE THAT FOLLOWS AND BE
ALERT TO THE POSSIBILITY OF PERSONAL IN-
JURY.
Remember, safety instructions stated in this
manual are for your protection. Read them
carefully and follow them closely when work-
ing around or using this machine.
NOTE: Due to continuing improvements in the design and manufacture of UNVERFERTH prod-
ucts, and normal changes in the marketplace, all specifications contained herein are subject to
change without notice.
INTRODUCTION
Your new ROLLING HARROW II is designed
and manufactured to give you years of de-
pendable service. To keep it running efficiently,
read the instructions in this operator's manual.
This manual covers operation, service, assem-
bly, and parts for your ROLLING HARROW II.
Read and study this manual completely be-
fore attempting to operate this implement. Take
this manual to the field for handy reference
when operating, adjusting, or servicing your
machine.
"Right-Hand" and "Left-Hand" side of the ma-
chine are determined by standing behind the
implement and facing in the direction of for-
ward travel.
No accident-prevention program can be successful without the wholehearted cooperation of the
person who is directly responsible for the operation of the equipment.
To read accident reports from all over the country is to be convinced that a large number of
accidents can be prevented only by the operator anticipating the result before the accident is
caused and doing something about it. No power-driven equipment, whether it be transportation or
processing, whether it be on the highway, in the harvest field, or in the industrial plant, can be
safer than the man who is at the controls. If accidents are to be prevented--and they can be
prevented--it will be done by the operators who accept the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help; and they will
help, but their combined efforts can be wiped out by a single careless act of the operator.
It is said that, "the best kind of a safety device is a careful operator." We, at Unverferth Mfg.
Co., Inc. ask that you be that kind of operator.
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!

SAFETY
AVOID POSSIBLE INJURY
Always use proper safety precautions. Most
accidents are a result of failure to practice
safety. Accidents cause lost time and suffer-
ing. Do not operate your ROLLING HARROW
II without thoroughly reading this manual.
Follow all safety precautions as outlined in
this manual, and in tractor and primary tillage
tool operator's manuals.
All machinery should be operated only by
those who are experienced, responsible, and
have been delegated to do so.
Never install additional equipment onto ROLL-
ING HARROW II such as spray tanks, etc. -
frame or axle failure could occur.
BEFORE OPERATING
Do not stand between tractor and primary
tillage tool during hitching.
Do not stand between primary tillage tool and
ROLLING HARROW II during hitching.
To avoid possible injury, lower implements to
the ground before servicing.
Always shut tractor engine off when working
on implements.
Avoid working under an implement; however, if
it becomes absolutely unavoidable, make sure
the implement is safely blocked.
Do not wear loose fitting clothes, as they
may catch in moving parts.
If a hydraulic leak develops, correct immedi-
ately. Escaping hydraulic fluid can be danger-
ous. Escaping fluid under pressure can
penetrate the skin causing serious injury.
Relieve the pressure before disconnecting hy-
draulic lines. Tighten all connections before
applying pressure. Keep hands and body away
from hydraulic leaks which eject fluid under
high pressure.
IF INJURED BY ESCAPING HYDRAULIC OIL,
SEE A DOCTOR AT ONCE, SERIOUS IN-
FECTION OR REACTION CAN DEVELOP IF
PROPER TREATMENT IS NOT ADMINIS-
TERED IMMEDIATELY.
Use a piece of cardboard or wood to detect
leaks of hydraulic fluid under pressure.
Be sure to relive all hydraulic pressure before
disconnecting any lines or pipes between the
implement and the tractor hydraulic system.
Keep all guards and shields in place.
When working around sweeps and points, be
careful not to be cut by sharp edges.
Only one person, the operator, should be per-
mitted on the tractor when implement is in op-
eration, and he should be thoroughly familiar
with the tractor before using the implement.
Always make certain everyone and everything
is clear of the machine before beginning op-
eration.
USING TRAIL HITCH
Be sure that the trail hitch is securely at-
tached to the primary tillage tool frame.
Be sure that members of the primary tillage
tool frame are adequate to support the ROLL-
ING HARROW II or other drawn equipment.
Tighten all hardware on the trail hitch after sev-
eral hours of use. Also, check periodically dur-
ing the season for worn or broken components.
When towing on roads, secure a safety chain
from the secondary tool to the trail hitch to
prevent accidental unhitching.
Do not stand between the primary and sec-
ondary tools when hitching, severe bodily harm
may occur.

SAFETY
DURING OPERATION
Do not allow anyone to ride on the equip-
ment. Make sure everyone is clear before
operating machine or tractor.
Regulate speed to field conditions. Maintain
complete control at all times.
Do not attempt to move any objects away
from moving parts.
Keep hands, feet, clothing, and objects away
from moving parts.
Do not grease or oil equipment when in op-
eration.
Use extreme care when operating close to
ditches, fences, or on hillsides.
Do not leave tractor or implement unattended
with engine running.
Never attempt to operate implement unless
you are in the driver's seat.
BEFORE TRANSPORTING
Secure the drawbar pin with safety lock be-
fore transporting.
Secure safety chain to implement and to draw-
bar before transporting.
Install transport locks before transporting. Make
sure that all safety decals, SMV emblem, and
reflectors are clean and in place on machine.
Latch tractor brake pedals together before
transporting.
Comply with state and local laws governing
highway safety when moving machinery.
Use accessory lighting or warning lights when
transporting at night to adequately warn op-
erators of other vehicles.
DURING TRANSPORT
Use good judgement when transporting imple-
ments on a highway. Maintain complete con-
trol at all times. Regulate speed to road
conditions. Maximum speed of a vehicle with
an implement should never exceed 20 m.p.h.,
and then only under ideal road and traffic
conditions.
Drive at speeds slow enough to insure your
safety as well as others.
Regulate speed during off highway travel. Do
not travel faster than 10 m.p.h.
Slow down before making sharp turns or us-
ing the brakes. Drive slowly over rough ground,
hillsides, and around curves to avoid tipping.
Due to the width of the implement, use extra
caution on highways, farm lanes, and when
approaching gates.

length of the hitch tube to give adequate turn-
ing clearance (between the two implements)
when turning on the ends.
NOTE: It may be necessary to reposition the
rear hose holder when adjusting the hitch tube
length.
Adjust the hitch tube length (as required) by
removing the two klik-pins (9951) and 1" dia.
pins (91363) in the front of the hitch frame.
Position as required and reinstall pins as before.
Back primary tillage tool into position, make
necessary adjustments (to align tongue and
implement hitch) and attach to the rear of
implement. Use a 1" dia. hitch pin and lock
in place.
NOTE: If unit is parked in the raised position,
turn handle on jackstand to remove pressure
and rotate jackstand into "Transport Position",
see "Jackstand" page 38).
OPERATIONS
HYDRAULICS
Check routing of all hydraulic hoses. Hoses
should not be kinked, twisted, or rubbing
against sharp edges. Hoses should be secure
with tie straps.
Check hoses and fittings for hydraulic leaks.
Tighten and/or repair or replace as required.
Refer to "Torque Chart" in SERVICE section.
LUBRICATIONS
Lubricate ROLLING HARROW II as out-lined
in SERVICE section.
TIRE PRESSURE
Check tire pressure. The recommended air
pressure for the transport tires is 40 PSI. Be
sure tire pressure is equal on all tires.
PREPARING ROLLING HARROW II
OM01408
Wear clips (Fig. 1-1) are provided on the ends
of each rolling harrow frame (two on the front
aggressive basket and one on the rear). They
are especially important when your ROLLING
HARROW II is used in wet sandy soils which
tends to build-up on end wheels of the bas-
kets. This highly abrasive soil can cause the
basket frame end plates to wear through or
damage zerk.
If operating under these conditions, be sure
the wear clips are in place, and the mounting
hardware is tight.
