INTRODUCTION
Your new ROLLING HARROW II is designed
and manufactured to give you years of dependable service. To keep it running efficiently,
read the instructions in this operator's manual.
This manual covers operation, service, assembly, and parts for your ROLLING HARROW II.
Read and study this manual completely before 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 machine are determined by standing behind the
implement and facing in the direction of forward travel.
THIS SYMBOL IDENTIFIES IMPOR-
TANT SAFETY MESSAGES. WHEN YOU SEE
IT, READ THE MESSAGE THAT FOLLOWS AND BE
ALERT TO THE POSSIBILITY OF PERSONAL INJURY.
Remember, safety instructions stated in this
manual are for your protection. Read them
carefully and follow them closely when working around or using this machine.
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!
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.
NOTE: Due to continuing improvements in the design and manufacture of UNVERFERTH products, and normal changes in the marketplace, all specifications contained herein are subject to
change without notice.

SAFETY
AVOID POSSIBLE INJURY
Always use proper safety precautions. Most
accidents are a result of failure to practice
safety. Accidents cause lost time and suffering. 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 ROLLING 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.
IF INJURED BY ESCAPING HYDRAULIC OIL,
SEE A DOCTOR AT ONCE, SERIOUS INFECTION OR REACTION CAN DEVELOP IF
PROPER TREATMENT IS NOT ADMINISTERED 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 permitted on the tractor when implement is in operation, 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 operation.
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 immediately. Escaping hydraulic fluid can be dangerous. Escaping fluid under pressure can
penetrate the skin causing serious injury.
Relieve the pressure before disconnecting hydraulic lines. Tighten all connections before
applying pressure. Keep hands and body away
from hydraulic leaks which eject fluid under
high pressure.
USING TRAIL HITCH
Be sure that the trail hitch is securely attached to the primary tillage tool frame.
Be sure that members of the primary tillage
tool frame are adequate to support the ROLLING HARROW II or other drawn equipment.
Tighten all hardware on the trail hitch after several hours of use. Also, check periodically during 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 secondary tools when hitching, severe bodily harm
may occur.

Keep hands, feet, clothing, and objects away
from moving parts.
Do not grease or oil equipment when in operation.
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.
DURING TRANSPORT
Use good judgement when transporting implements on a highway. Maintain complete control 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 using 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.
BEFORE TRANSPORTING
Secure the drawbar pin with safety lock before transporting.
Secure safety chain to implement and to drawbar before transporting.
Install transport locks before transporting. Make
sure that all safety decals, SMV emblem, and
reflectors are clean and in place on machine.

for tightness. Recheck all bolts for tightness,
after the unit has been operated for several
hours.
PINS AND RETAINING RINGS
Before going to the field, check that all pins
and retaining rings are in place and are in
good condition. Replace any worn, damaged,
or missing pins and retaining rings.
ROLLING HARROW WEAR CLIPS
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 baskets. This highly abrasive soil can cause the
basket frame end plates to wear through or
damage zerk.
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.
If operating under these conditions, be sure
the wear clips are in place, and the mounting
hardware is tight.
ATTACHING ROLLING HARROW II TO PRIMARY
TILLAGE TOOL
Before attaching the ROLLING HARROW II to
your primary tillage tool, adjust the extended
length of the hitch tube to give adequate turning 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.
FIG. 1-1
Back primary tillage tool into position, make
necessary adjustments (to align tongue and
implement hitch) and attach to the rear of

ESCAPING HYDRAULIC FLUID UNDER PRESSURE
CAN CAUSE BODILY INJURY.
IMPORTANT: If the hoses have been disconnected from the hydraulic cylinders or if the
cylinders have not been used for some time,
note the following warning.
WARNING! PURGING AIR FROM CYL-
INDERS MUST BE DONE BEFORE HYDRAULIC OPERATION MAY SAFELY BE USED. FAILURE
TO DO THIS COULD RESULT IN SERIOUS INJURY
OR DAMAGE TO IMPLEMENT.
NOTE: Refer to ASSEMBLY section (page 35
and 36) for procedures on the purging process and hydraulic system checks.
NOTE: Refer to SERVICE section (pages 18
to 20) when checking hydraulic circuit operation and function.
HYDRAULIC HOOK-UP INTO A CIRCUIT
USING REPHASE CYLINDERS: (Fig. 1-3)
When connecting the ROLLING HARROW II
hydraulic system into an existing circuit (on
the primary tillage tool) using rephase hydraulic cylinders, a "Pilot Operated Check Valve"
is required to insure the ROLLING HARROW
will remain in the transport position.
Install the pilot operated check valve (UNVERFERTH MFG. CO., INC. #91240) onto the rear
of the primary tillage tool. Connections from
the rephase system must be installed into the
ports (of the valve) that are closest together.
Connections to the ROLLING HARROW II system go into the other two ports.
Raise unit into transport position and install
cylinder transport locks (Fig. 1-4).
CAUTION! SHUT-OFF TRACTOR ENGINE
\AND WORK CONTROL LEVERS BACK AND

CHAIN WHEN TRANSPORTING IMPLEMENTS. FAILURE TO USE SAFETY CHAINS COULD
CAUSE PERSONAL INJURY OR DAMAGE IF IMPLEMENTS BECOME DISENGAGED.
ING HARROW II unfold, move the unit forward
(slowly) as the wings begin to contact the
ground. This will allow the teeth and baskets on
the unit to roll on top of the soil, preventing
them from jamming sideways into the ground,
causing possible damage to the unit.
WITH TRANSPORT
LOCKS IN PLACE
After the wing unfolding cycle is complete, reverse the flow of hydraulic oil in the system
enough to fully extend the wheel hoist cylinders
(but do not refold the wings). Remove wheel
hoist cylinder transport locks (Fig. 1-4), so unit
may be lowered to the field-working position.
Install safety chain (as shown in Fig. 1-5).
IMPORTANT: Picture shown with hook-up between tractor and primary tillage tool. Safety
chain must also be installed between primary
tillage tool and ROLLING HARROW II.
NOTE: Safety chain should have a test strength
equal to the gross weight of implement and
all attachments.
TRANSPORTING
IMPORTANT: Before unit is transported, be
sure the jackstand is in the "Transport Position" see "Jackstand" (page 38).
CAUTION! INSTALL HYDRAULIC CYL-
INDER TRANSPORT LOCKS BEFORE
TRANSPORTING (FIG. 1-4).
Comply with all state and local laws governing
highway safety and regulations when moving
machinery on public roads.
Be sure SMV Emblem is in place and clearly
visible on the rear of the implement. See
SMV Emblem (page 39).
CAUTION! USE APPROVED ACCES-
SORY LIGHTS, REFLECTORS AND DEVICES WHEN TRANSPORTING AT NIGHT AND
DURING PERIODS OF POOR VISIBILITY.
IMPORTANT: Check transport route clearance,
and refer to model specifications in primary
tillage tools operator's manual, and on ROLLING HARROW II (in front of manual) for transport dimensions of implements.
For safe transporting of these implements, the
transport speed should never exceed 10 M.P.H.
in the field or over rough terrain. Reduce transport speed to maintain full control of the implement and tractor at all times.
Reflective tapes are provided with this implement. Red reflective tape should be in place
on the back and outermost extremity of the
rear frame tube on each side. The amber
reflective tape should be in placed on the left
hand front extremity of the front frame tube.
Be sure these reflectors are in place and
clearly visible. See reflectors (page 40).

CAUTION! SERIOUS PERSONAL INJURY
CAN RESULT IF YOU ATTEMPT TO DISCONNECT HYDRAULIC HOSES UNDER PRESSURE.
SHUT OFF TRACTOR ENGINE AND WORK LEVERS
BACK AND FORTH BEFORE DISCONNECTING
HOSES.
Disconnect the hydraulic hoses. Install dust
covers over the hose plugs and outlets.
IMPORTANT: Before unhitching the primary
tillage tool, refer to the units "Operator's
Manual" for unhitching procedures.
ROLLING HARROW BASKET
The Rolling Harrow basket is designed to help
provide an excellent seed-bed when used in
conjunction with your primary tillage tool.
To obtain maximum performance from your
ROLLING HARROW II in the field, it may be
run with the transport wheels in the "Raised"
or "Float" position. This allows maximum transfer of weight to the baskets, thus providing for
better leveling and ground working action (by
allowing the unit to more closely follow the
ground contour).
Normally the ROLLING HARROW II should
run with the basket frame in the free-floating
position (allowing the unit to more closely
follow the ground contour and roll over rocks
and obstructions in the field), thus prolonging
the life of the baskets. To obtain a "FreeFloating" basket frame, remove lock-out pins
from basket frame and store in mounting arms
(Fig. 1-6).
In some conditions, it may be desirable to
limit the float of the basket frame:
LIMIT FLOAT
A. Raise ROLLING HARROW II to transport
position.
B. Remove pin from storage position and
place in desirable hole in basket frame.
NOTE: Place pin in slot for maximum lock-out.
Be sure to position pins in the same hole from
side-to-side on each basket section.
IMPORTANT: IN ROCKY CONDITIONS, the
life of the baskets may be shortened if the
unit is pinned with the front basket locked in
the down position.
NOTE: IN LIGHTER SOILS, depending on the
depth, speed, and soil condition, it may be
desirable to limit the penetration of the front
basket, by placing the lock-out pin in one of
the three holes (in basket frame) on the backside of the mounting arm.
FIG. 1-6
OM-01406
NORMAL POSITION
ROLLING HARROW II RUN WITH AGGRESSIVE BASKET POSITIONED TO THE FRONT
(FIG. 1-6) FOR MAXIMUM PENETRATION IN
NORMAL SOIL CONDITIONS.
A maximum amount of leveling and conditioning of the soil is obtained when the aggressive basket is positioned to the front (as shown
in Fig. 1-6). This position also helps provide
for thorough mixing of chemicals into the top
two to three inches of the soil, when used for
incorporation.

is positioned at the rear (as shown in Fig. 1-7).
FIG. 1-7
NOTE: To reverse Rolling Harrow baskets,
remove mounting pin (82381) and spiral pin
(91144-186) (Fig. 1-7) connecting basket frame
to spring arm, rotate basket frame and reinstall mounting pins and spiral pins.
NOTE: Notice position of wear clips. Refer to
page 10 for installation of "Wear Clips".
ONE-BAR/LEVELER
The one-bar is designed to improve the soil
leveling capabilities of your ROLLING HARROW II. The one-bar spring pressure can be
increased to improve ground leveling by tightening the adjusting screw or decreasing to
improve trash flow by loosening the adjusting
screw. This adjustment is especially important
in heavy soils or trashy conditions, by improving soil leveling and/or trash flow.
TO ADJUST SPRING PRESSURE:
(Fig. 1-8A & Fig. 1-8B).
A. Loosen locknut.
B. TO INCREASE SPRING PRESSURE, turn
adjusting screw in (Fig. 1-8A & 1-8B).
TO DECREASE SPRING PRESSURE, turn
adjusting screw out (Fig. 1-8A & 1-8B).
*
NOTE: Depending on which adjustment screw
you have, the Initial spring pressure adjustment screw should be set at 3/4" minimum
for 1/2-13 x 1 1/2" lg. screw (9390-101) and
1 3/4" minimum for 1/2-13 x 2 1/2" lg. screw

LUBRICATION
ROLLING HARROW BEARINGS
Lubricate with an SAE multi-purpose grease.
All fittings must be free from dirt and paint to
insure entry of lubricant inside bearing.
Lubricate these bearing every 100 hours of
operation and at the end of each season,
before storage. Use only one stroke of grease
per bearing.
CAUTION! DO NOT USE A HIGH-
PRESSURE GREASE GUN TO LUBRICATE
THESE BEARINGS, AS DAMAGE TO BEARING SEAL
COULD OCCUR.
NOTE: Excessive lubrication of these bearings will result in premature failure.
WHEEL BEARINGS
The wheel bearings should be cleaned, repacked, and adjusted once per season. Use a
number 2 wheel bearing grease to repack the
bearings to a free rolling fit with no end play.
STORAGE
Your implement is an important investment.
Spend a little time to protect it from destructive rust and corrosion. You will be repaid in
longer service life and better performance.
Do the following before placing the implement
in storage:
1. Remove dirt and trash which could cause
rusting.
2. Repaint any chipped or scraped areas.
3. Coat all earth moving surfaces with grease
or suitable rust preventative.
4. Inspect for damage or worn parts, replace before next season.
5. Store implement inside, away from livestock.
6. Use blocking to keep implement tires and
points up off bare ground.
INSTALLING RETAINING RINGS
1. USE PROPER TOOLS for assembling
rings onto pins (for plain external retain-
ing rings use a flat-blade retaining ring
pliers).
2. Before inserting pins, be sure the
GROOVE IS FREE FROM ALL FOREIGN
MATERIAL (paint, dirt, etc.), to ensure a
proper seating.
3. DO NOT OVERSTRETCH RING during
assembly. Install ring into groove so that
it is securely seated and will not rotate
around the pin.
BASIC EXTERNAL RETAINING RINGS
4. BASIC EXTERNAL RETAINING RINGS
On "D" shaped pins, the retaining ring
OPENING SHOULD BE APPROXIMATELY
180o FROM THE FLAT of the pin (Fig. 2-1).
PLAIN EXTERNAL RETAINING RINGS
On "D" shaped pins, the retaining ring
OPENING SHOULD BE OVER THE FLAT
of the pin (Fig. 2-2).
NOTE: The retaining rings should fit tightly
once released and should not rotate freely.

REPLACING ROLLING HARROW BASKET BEARINGS
IMPORTANT! SAFETY GLASSES MUST BE
WORN WHILE REPLACING A BEARING.
1. Lower baskets of the ROLLING HARROW
to the ground and block the tires.
2. Remove pins (82381 and 91523) from the
basket with the worn bearing. Raise the
complete ROLLING HARROW into transport position.
3. Slide the two baskets and the frame away
from the others so it can be worked on.
4. Remove the three 5/16-18 capscrews/carriage bolts and the clip(s) which hold the
bearing on and note the placement of
the clip(s) and the longer 5/16-18
capscrew(s)/carriage bolt(s).
5. Use a crowbar to pry the end of the
basket from out of the basket frame slot.
6. Loosen the set screw in the lock collar.
Loosen lock collar by turning with punch
in direction of basket travel.
7. Place a punch through the hole in the
end plate on the basket and use a hammer to remove the bearing. If the bearing
is on too tight, use a bearing puller to
remove the bearing.
8. File off any burrs left on the shaft. Finish
with a strip of emery cloth. Make sure
bearing will slide on the shaft.
9. BEARING (9808) FIG. 2-1
Slide a new flangette with lube fitting
(92282) and lock collar/bearing (9808) toward the basket on the end of the shaft.
BEARING (96563) FIG. 2-2
Slide a new bearing (96563) on the shaft
so the lock collar will be on the outside.
10. BEARING (9808) FIG. 2-1
Place the other flangette (92281) against
the bearing and pry the end of the basket into the slot of the frame.
BEARING (96563) FIG. 2-2
Pry the end of the basket into the slot of
the frame.
11. BEARING (9808) FIG. 2-1
Assemble 5/16-18 capscrews through both
flangettes, the clip(s) and the frame.
BEARING (96563) FIG. 2-2
Assemble the 5/16-18 carriage bolts
through the holes in the bearing housing,
the clip(s), and the frame.
NOTE: Use the other side of the basket as
a sample of how the capscrews should be
assembled.
IMPORTANT: Tighten 5/16-18 capscrews before you tighten the setscrew in the lock
collar. Turn lock collar in the opposite di-
rection of travel. Tighten capscrew according
to "Torque Chart" page 21.
12. Reassemble the basket assembly to the
frame with pins (82381 and 91523).

NOTE: For plumbing diagram, refer to "Hydraulic Diagram 1". Refer to PARTS section
(pages 58 to 59) for hydraulic components
detail listing.
HYDRAULIC DIAGRAM #1
OPERATION (HOW IT WORKS)
All cylinders on the ROLLING HARROW II are
double action cylinders. They are all teed
together into one circuit. Because of orifices
placed in the wing-fold segment of the circuit,
the wheel axle cylinders will extend first, followed by retracting of the wing-fold cylinders.
When hydraulic oil is directed in the opposite
direction, the wheel axle cylinders will retract
first, followed by extending of the wing fold
cylinders.

NOTE: For plumbing diagram, refer to "Hydraulics Diagram 2". Refer to parts section (pages
60 to 63) for hydraulic component detail listing.
OPERATION (HOW IT WORKS)
All cylinders on the ROLLING HARROW II are
double acting cylinders. They are all teed
together into one circuit. Because of orifices
placed in the wing-fold segment of the circuit,
the wheel axle cylinders will extend first, followed by retracting of the wing-fold cylinders.
IMPORTANT: Refer to page 28-29 for proper
wing and valve combination of your machine.
HYDRAULIC DIAGRAM #2
The stack fold valve is a pilot operated, double
bi-pass valve. This valve allows oil to flow to
one outlet port or the other in one direction,
and free-flow (from both ports) in the opposite
direction.
The stack fold valve allows the L.H. wing to
fold first, until the wing contacts the valve
(shifting the spool of the valve), followed by
the folding of the R.H. wing.
When hydraulic oil is directed in the opposite
direction, the wheel axle cylinders will retract
first, followed by (because of difference in the
wing position from right-to-left) extending the
R.H. wing fold cylinder.
