SAFETY
WATCH FOR THIS SYMBOL. IT IDENTIFIES IMPORTANT SAFETY MESSAGES. WHEN YOU SEE THIS SYMBOL, READ THIS SAFETY MESSAGE
CAREFULLY.
GENERAL SAFETY
1. Never allow anyone to ride on the tractor drawbar, or on the cultivator. The person(s) riding may fall and be seriously or fatally injured.
2. Machinery should be operated ONLY by persons responsible and qualified to do so.
3. Never allow anyone to climb or play on the tractor or cultivator. They may fall and be seriously injured.
4. Follow all safety precautions in your cultivator manual.
5. Keep a First Aid Kit in the tractor at all times.
ASSEMBLY SAFETY
1. Use an aligning punch to line up holes. Keep your fingers out of these holes. Any sudden movement of heavy components will severely injure or
sever your fingers.
2. Use a hoist or adequate manpower to lift the heavy components into place. Use adequate jacks or support materials. Attempting to lift heavy
components by yourself could cause serious injury.
3. Be sure all bolts and hydraulic fittings are tight, and all cotter pins are installed in the slotted nuts and pins.
4. Support the main and wing frames securely before assembling the components. Inadequate support may result in the heavy components falling
and causing serious injury to you and person(s) nearby.
5. Be sure all wheel bolts are checked for tightness during initial transport or when first cultivating. Loose wheel bolts may result in the wheel
falling off, causing serious damage to the cultivator and may cause serious injury to the operator or person(s) nearby.
6. To fill the wing lift cylinders with hydraulic fluid, remove the pin from the shaft end of each wing lift cylinder and pump fluid into the cylinders.
Extend and contract the cylinders until they are completely filled with hydraulic fluid. The wings will free-fall if the cylinders are not completely
filled with fluid, resulting in serious damage.
7. Do not raise or lower the main or wing frames until all components are securely tightened. Loose components will cause serious damage to the
cultivator and serious injury or death to you and person(s) nearby if the main or wing frames fell.
8. Before applying pressure to the hydraulic system, be sure all connections are tight and the components are not damaged.
9. When moving, positioning or attaching the castor wheel
assemblies, use extreme care not to place any portion of your
body (such as your hands, arms or legs) between the top and
bottom links. These links could collapse, causing serious
injury.

MAINTENANCE SAFETY
1. Do not loosen or disassemble hydraulic components when there is pressure within those components. Hydraulic components under pressure
may cause parts and hydraulic fluid to fly out at a high velocity, which could cause serious injury. Always relieve the pressure in the hydraulic
system before making adjustments to the hydraulic system.
2. Check all hydraulic hoses periodically for signs of ruptures and leaks. Always use wood or cardboard as a backstop, and wear gloves and eye
protection when searching the hydraulic system for leaks. Spurting hydraulic fluid can cause injury if it penetrates the skin or the eyes. If
injured by escaping hydraulic fluid, see a medical doctor immediately.
3. Always relieve the pressure in the hydraulic system when the cultivator is not being operated.
4. Always permit parts which contain hot fluid to cool to a safe temperature before handling or disconnecting these parts.
5. Always wear safety glasses or goggles and gloves when working on the hydraulic system.
6. Be sure all hydraulic cylinders are completely filled with hydraulic fluid to avoid wing free-fall or sudden movement. If the hydraulic cylinders
are not completely filled, the wings will free-fall, resulting in serious damage to the cultivator and serious injury or death to you or those nearby.
7. Lower the cultivator to the ground when servicing. If the cultivator must be serviced in the raised position, install the full set of depth control
segments on the rockshaft cylinder. Then lower cultivator until cylinder hits stops. If the hydraulic system failed, or if the hydraulic lever was
accidentally operated, the cultivator could drop.
8. Do not service or adjust the cultivator when it is in motion. You may fall and be seriously or fatally injured.
9. Always put all tractor controls in neutral, set the park brake and shut the engine off before servicing the cultivator. If the tractor and cultivator
were to roll, you could be seriously or fatally injured.
10. If wing lift cylinder(s) is removed when wings are folded into transport position, always install a safety chain between each wing frame and
main frame to prevent wings from falling. If wings fell serious injury or death could occur to person(s) nearby and machine would be damaged
severely.
TRANSPORT SAFETY
1. Use the "SMV" emblem and warning lights for the protection of the tractor and other motor vehicle operators when transporting the cultivator.
Check local laws regarding transport regulations.
2. When transporting the cultivator, always lock the rockshaft by installing depth control segments on lift cylinder. If the hydraulic system failed, or
if the hydraulic lever was accidentally operated, the cultivator could drop, resulting in serious damage to the cultivator and serious injury or
death to you or those nearby.
3. Do not exceed 10 mph (16 km/h) when transporting the cultivator on smooth surfaces. Reduce your speed on rough surfaces. Do not transport
the cultivator with any other vehicle except a tractor.
4. When transporting the cultivator with the wings folded (UP), be sure there is sufficient clearance under all power lines and other overhead
obstructions. Serious injury or death can result from contact with electrical lines. Use care to avoid contact with electrical lines when moving or
operating the cultivator.
5. Always close hydraulic lock up valves before transporting cultivator. If hydraulic levers were accidentally operated during transport, serious
injury or death to person(s) nearby or serious damage to cultivator could result from the wings falling or machine dropping.
Page 3

TRANSPORT SAFETY CONTINUED:
6. Always attach a safety chain to the tractor drawbar and
the cultivator hitch before transporting the cultivator.
Serious damage and injury could result from the
cultivator separating from the tractor drawbar.
7. Always lock the wings in the folded position with the transport locks before transporting the cultivator. Serious damage to the cultivator and
serious injury or death could result from the wings falling during transport.
8. Check all reflectors for visibility and cleanliness before transporting the cultivator. It is important that the reflectors are clean and visible,
especially during the evening hours.
9. Regulate your speed on hillsides and curves when transporting the cultivator. Loss of tractor control could result in serious damage to the
cultivator and possible serious injury or death to you or those nearby.
OPERATION SAFETY
1. Be sure person (s) are standing clear before starting or moving the tractor and cultivator.
2. Only one (1) person (the operator) should be permitted on the tractor when the cultivator is in operation, and he/she should be familiar with
repair procedures and temporary first aid treatment.
3. Never stand between the tractor and cultivator when hitching the cultivator to the tractor, UNLESS all tractor controls are in neutral and the park
brake is set. The tractor could roll backwards, which could result in serious injury or death to you or those nearby.
4. Use extra care when operating the cultivator on hillsides. The tractor may tip over if it strikes a hole, ditch or other irregularity, resulting in
serious injury or death to the operator or those nearby.
SAFETY DECALS
1. Keep all decals clean and in good condition to provide you with a constant reminder of safe operating procedures.
2. Replace any destroyed, missing or illegible decals.
STORAGE
IMPORTANT: WINGS MAY UNFOLD DUE TO THERMAL EXPANSION OF
HYDRAULIC OIL CAUSING DAMAGE TO CULTIVATOR, PROPERTY
OR SEVERE INJURY OR DEATH TO PERSON(S) NEARBY. RELEASE
PRESSURE IN ALL CYLINDERS THEN CLOSE HYDRAULIC
LOCKUPVALVESBEFORE UNHITCHING FROM TRACTOR OR
WHEN PARKING WITH TRACTOR.
Page4
5. To avoid personal injury or death, always stay clear of the folding
wings when they are being raised, lowered or in the folded position.
If the hydraulic system failed, or if the hydraulic lever was
accidentally operated, the wings could drop, resulting in serious
injury or death to you or those nearby.
6. Always relieve the pressure in hydralic system and close both lockup
valves when the cultivator is not being operated.

1.
FIELD OPERATION
A) See Fig. 1. Open both hydraulic lock up valves located
at front of center frame. Position levers as shown. This
will allow hydraulic oil to flow to hydraulic cylinders.
B) Remove the wing lock-up pins and lower wings to field operating position.
CAUTION: BE SURE PERSON(S) ARE STANDING CLEAR BEFORE STARTING OR MOVING THE TRACTOR AND CULTIVATOR.
IMPORTANT: ONLY ONE (1) PERSON (THE OPERATOR) SHOULD BE PERMITTED ON THE TRACTOR WHEN THE CULTIVATOR IS IN OPERATION,
AND HE/SHE SHOULD BE FAMILIAR WITH REPAIR PROCEDURES AND TEMPORARY FIRST AID TREATMENT.
C) Be sure wing lift cylinders are fully extended when wings are lowered to field position. If the cylinders are not fully extended, the wings
will hang on the cylinders, and will not flex down.
IMPORTANT: AFTER THE WING TIRES HAVE TOUCHED DOWN, CONTINUE TO HOLD DOWN THE HYDRAULIC LEVER. THERE IS A SHORT PAUSE
BEFORE THE CYLINDERS FULLY EXTEND.
D) Insure that the tractor drawbar is pinned in the center position.
E) Insure that the front and rear shovels are level, and the wings are level with the main frame. Set the cutting depth as required. See
Field Adjustments on page 11.
F) Use a tractor speed that will provide the desired cutting action.
IMPORTANT: DO NOT OPERATE THE CULTIVATOR WITH THE FRONT SHOVELS CUTTING DEEPER THAN THE REAR SHOVELS.
IMPORTANT: INSURE THE HITCH JACK IS PINNED IN THE HORIZONTAL POSITION.
WARNING: NEVER STAND BETWEEN THE TRACTOR AND CULTIVATOR WHEN HITCHING THE CULTIVATOR TO THE TRACTOR
UNLESS ALL TRACTOR CONTROLS ARE IN NEUTRAL AND THE PARK BRAKE IS SET. THE TRACTOR COULD ROLL,
WHICH COULD RESULT IN SERIOUS INJURY OR DEATH TO YOU OR THOSE NEARBY.
WARNING: USE EXTRA CARE WHEN OPERATING THE CULTIVATOR ON HILLSIDES. THE TRACTOR MAY TIP OVER IF IT STRIKES
A HOLE, DITCH OR OTHER IRREGULARITY, RESULTING IN SERIOUS INJURY OR DEATH TO THE OPERATOR AND THOSE
NEARBY.
Page 7
DANGER: TO AVOID PERSONAL INJURY OR DEATH, ALWAYS

CAUTION: USE THE "SMV" EMBLEM (NOT SUPPLIED BY EZEE-ON)
AND WARNING LIGHTS FOR THE PROTECTION OF THE
TRACTOR AND OTHER MOTOR VEHICLE OPERATORS WHEN
TRANSPORTING THE CULTIVATOR OVER PUBLIC ROADS.
CHECK LOCAL LAWS REGARDING TRANSPORT
REGULATIONS.
B) Raise cultivator out of ground then fold wings.
C) See Figure 4. After wings are folded install one transport lock pin in each
wing. Secure transport pin with (1) hair pin.
WARNING: ALWAYS LOCK THE WINGS IN THE FOLDED POSITION WITH
THE TRANSPORT LOCKS BEFORE TRANSPORTING THE
CULTIVATOR. SERIOUS DAMAGE TO THE CULTIVATOR AND
SERIOUS INJURY OR DEATH COULD RESULT FROM THE

D) See Fig 5. Close hydraulic lock-up valves located at front
of center frame. Position levers as shown. This will lock
hydraulic oil in cylinders preventing accidental operation of
hydraulic system during transport.
CAUTION: ALWAYS CLOSE HYDRAULIC LOCK UP VALVES
BEFORE TRANSPORTING CULTIVATOR. IF
HYDRAULIC LEVERS WERE ACCIDENTALLY
OPERATED, SERIOUS INJURY OR DEATH TO
PERSON(S) NEARBY OR SERIOUS DAMAGE TO
CULTIVATOR COULD RESULT FROM THE WINGS
FALLING OR MACHINE DROPPING.
E) See Fig. 6 Attach a safety chain to the tractor drawbar and
the cultivator. Use a safety chain with sufficient strength
to withstand a force greater than the gross weight of
implement’s being towed.
CAUTION: ALWAYS ATTACH A SAFETY CHAIN TO THE
TRACTOR DRAWBAR AND THE CULTIVATOR HITCH
BEFORE TRANSPORTING THE CULTIVATOR.
SERIOUS INJURY OR DEATH AND SERIOUS
DAMAGE TO THE CULTIVATOR COULD RESULT
FROM THE CULTIVATOR SEPARATING FROM THE
TRACTOR DRAWBAR.
F) See Fig. 7. Install all depth control segments [total length
of 11-1/4” (285.75mm)] on rockshaft cylinder before
transporting the cultivator.
WARNING: BEFORE TRANSPORTING THE CULTIVATOR
ALWAYS LOCK THE ROCKSHAFT BY INSTALLING
ALL THE DEPTH CONTROL SEGMENTS (11-1/4”Lg)
ON ROCKSHAFT CYLINDER. IF THE HYDRAULIC
LEVER WAS ACCIDENTLY OPERATED OR IF THE

FIXED TYPE TOW HITCH (EZEE-ON HITCH SHOWN)
APPROX. 5°
HITCH OF TOWED
EQUIPMENT * SEE
NOTE ABOVE
3. TOWING EQUIPMENT
A) See Figure 8. When towing equipment behind cultivator with fixed type tow hitch, the hitch of the towed equipment must be attached
low enough so the equipment’s hitch slopes down towards the cultivator at approximately a 5 degree angle. *(Ezee-On and Dutch Air
Seeders with 2 wheels will have its hitch slope up towards tow hitch. The hitch must also be attached low to obtain a balanced line of
draft.)
If towed equipment is attached too high it will pull rear of cultivator down causing uneven shank penetration.
If tow hitch other than Ezee-On is used, it may have to be modified so towed equipment can be hitched lower.
If you are using hitch supplied with Cereal Implement’s Chinook Air Seeder, Ezee-On has a lowering kit available.
NOTE: A fixed tow hitch is used to tow the Model 135 or 160 Ezee-On Air Carts or Chemical Tanks.
CAUTION: DO NOT EXCEED 10 mph (16 km/h) WHEN TRANSPORTING THE CULTIVATOR ON SMOOTH SURFACES. REDUCE YOUR SPEED
ON ROUGH SURFACES. DO NOT TRANSPORT THE CULTIVATOR WITH ANY OTHER VEHICLE EXCEPT A TRACTOR.
DANGER: WHEN TRANSPORTING THE CULTIVATOR WITH THE WINGS FOLDED (UP) BE SURE THERE IS SUFFICIENT CLEARANCE UNDER
ALL POWER LINES AND OTHER OVERHEAD OBSTRUCTIONS. SERIOUS INJURY OR DEATH CAN RESULT FROM CONTACT WITH
ELECTRICAL LINES. USE CARE TO AVOID CONTACT WITH ELECTRICAL LINES WHEN MOVING OR TRANSPORTING THE
CULTIVATOR.
WARNING: REGULATE YOUR SPEED ON HILLSIDES AND CURVES WHEN TRANSPORTING THE CULTIVATOR. LOSS OF TRACTOR CONTROL
COULD RESULT IN SERIOUS DAMAGE TO THE CULTIVATOR AND POSSIBLE SERIOUS INJURY OR DEATH TO YOU OR THOSE
NEARBY.
IMPORTANT: CHECK ALL REFLECTORS FOR VISIBILITY AND CLEANLINESS BEFORE TRANSPORTING THE CULTIVATOR. IT IS IMPORTANT THAT
THE REFLECTORS ARE CLEAN AND VISIBLE, ESPECIALLY DURING THE EVENING HOURS.
Page 10

OPERATION CONTINUED:
4. FIELD ADJUSTMENTS - Levelling Cultivator
A) See Fig 9. To level wing frames with center section,
raise or lower each wing with a quick leveler, arrow 1.
These quick levellers are located between wing rockshaft
and intermediate rockshaft. To adjust quick levellers,
loosen locknut, then adjust center body of leveller as
required. After adjustments are complete, tighten lock
nut.
B) See Fig 10. To level cultivator from front to rear, raise or
lower front of cultivator by adjusting length of castor
wheel links, arrow 1. When levelling cultivator from
front to rear, the wing castor wheels should be adjusted
first. Then adjust center section caster wheel so it is at
same height as wing castor wheels. The two (2) wing
frame castor wheel assemblies usually carry the front of
cultivator when cultivating. The center castor wheel will
not carry a great amount of weight. Center castor wheel
will only carry load when center section goes over a
ridge or when cultivator is placed in transport position.
C) Use the following procedures to check if cultivator is
level:
(C1) Lower cultivator completely to ground. The tires
should not be carrying any weight.
(C2) Raise cultivator so front center section shovels
are approximately 1" (25.4mm) off ground.
(C3) Check height of shovels’on front and rear rank
of each wing and center section.
(C4) If front and rear shovels are not at same height,
adjust linkage as described in section A and B
and repeat Section C.
D) Further adjustments may be required in the field
depending on field conditions. If wings are cutting too
deep or not deep enough, simply correct with quick
leveller on wings.

OPERATION CONTINUED:
E) See Fig. 11. The cutting depth is controlled by
installing segment collars on the rockshaft cylinder
shaft. Five (5) segments vary in length from 5/8" to
2" (16mm x 50.8mm). Table III on page 13 shows
the segment combination required to obtain a
desired stroke combination.
F) See Fig. 12. The springs on the shank trip
assemblies are tightened as follows after spring I-
Bolts become snug:
(8) turns for Model 3550 Cultivator (350 lb. trip);
(10) turns for Model 5550 Cultivator (550 lb. trip). If
shank is not holding ground tool in desired position
due to soil conditions. Springs can be tightened to
obtain more pressure.
IMPORTANT: BE SURE ALL BOLTS ARE CHECKED
PERIODICALLY FOR TIGHTNESS.
SPECIAL ATTENTION SHOULD BE GIVEN
TO 3/4" (19.0mm) PIVOT BOLTS ON THE
SHANK TRIP ASSEMBLIES. IF THE BOLTS
COME LOOSE, THE TRIP MOUNT
BRACKETS COULD BE DAMAGED.

Page 14

LUBRICATION CONTINUED: (SECTION 1)
C) See Fig. 14. Lubricate the rockshaft cylinder pins with oil once
every 40 hours of operation. Be sure to coat the pin holes of
shaft end clevis and pin hole in rockshaft arm.
2. MAINTENANCE
A) All bolts and nuts should be checked periodically to make sure
they are tight. Special attention should be given to the 3/4"
(19.0mm) pivot bolt on the shank trip assembly. If this pivot
bolt comes loose, the trip mount bracket could be
damaged.
Also give special attention to all ball joint linkage bolts on rockshaft system. These bolts must be tightened to 840 foot pounds (1137 N.m). If the
ball joint bolts are loose, the ball joints and bolts will wear causing excessive slack between the rockshafts, making even depth control difficult.
Tighten as follows:
-Shank U-Bolt 5/8” (15.7mm) diameter – 150 ft. lbs. (203 N.m)
-Shank pivot bolt ¾” (19.0mm) diameter – 265 ft. lbs. (359 N.m)
-Wheel bolts 9/16” (14.3mm) diameter – 130 ft. lbs. (176.3 N.m)
-Rockshaft linkage bolt 1-1/4” (31.7mm) diameter – 840 ft. lbs. (1139 N.m)
-Stub extension U-Bolt 5/8” (15.7mm) diameter – 150 ft. lbs. (203 N.m)
B) Check the tire pressure in all tires every one hundred (100) hours. Maintain equal pressure in all tires. Refer to specifications on page 5 for tire
pressure. Check the tire tread periodically for nicks, cuts or abrasions.
CAUTION: ALWAYS RELIEVE THE PRESSURE IN THE HYDRAULIC SYSTEM WHEN THE CULTIVATOR IS NOT BEING OPERATED.
CAUTION: CHECK ALL HYDRAULIC HOSES PERIODICALLY FOR SIGNS OF RUPTURES AND LEAKS. ALWAYS USE WOOD OR CARDBOARD AS
A BACKSTOP, AND WEAR GLOVES AND EYE PROTECTION WHEN SEARCHING THE HYDRAULIC SYSTEM FOR LEAKS. SPURTING
HYDRAULIC FLUID CAN CAUSE INJURY IF IT PENETRATES THE SKIN OR THE EYES. IF INJURED BY ESCAPING HYDRAULIC
FLUID, SEE A MEDICAL IMMEDIATELY.
CAUTION: BE SURE ALL HYDRAULIC CYLINDERS ARE COMPLETELY FILLED WITH HYDRAULIC FLUID TO AVOID WING FREE-FALL OR
SUDDEN MOVEMENT. IF THE HYDRAULIC CYLINDERS ARE NOT COMPLETELY FILLED, THE WING WILL FREE-FALL, RESULTING
IN SERIOUS INJURY OR DEATH TO YOU OR THOSE NEARBY.
C) Keep all decals clean and in good condition to provide you with a constant reminder of safe operating procedures.
D) Replace any destroyed, missing or illegible decals and reflectors.
CAUTION: DO NOT LOOSEN OR DISASSEMBLE HYDRAULIC COMPONENTS WHEN THERE IS PRESSURE WITHIN THOSE COMPONENTS.
ESCAPING HYDRAULIC FLUID UNDER PRESSURE HAS SUFFICIENT FORCE TO PENETRATE SKIN. ALWAYS RELIEVE THE
PRESSURE IN THE HYDRAULIC SYSTEM BEFORE MAKING ADJUSTMENTS TO THE HYDRAULIC SYSTEM.
CAUTION: ALWAYS PERMIT PARTS WHICH CONTAIN HOT FLUID TO COOL TO A SAFE TEMPERATURE BEFORE HANDLING OR
DISCONNECTING THESE PARTS.
CAUTION: ALWAYS WEAR SAFETY GLASSES OR GOGGLES AND GLOVES WHEN WORKING ON THE HYDRAULIC SYSTEM.
CAUTION: ALWAYS PUT ALL TRACTOR CONTROLS IN NEUTRAL, SET THE PARK BRAKE AND SHUT ENGINE OFF BEFORE SERVICING THE
CULTIVATOR. IF THE TRACTOR AND CULTIVATOR WERE TO ROLL, YOU COULD BE SERIOUSLY INJURED.

MAINTENANCE CONTINUED: (SECTION 2)
E) Replacing Walking Beam Bearings - See Fig. 15, 16, 17 and 18.
E1) Remove old bearing cups from walking beam bearing tube then
install two (2) new cups (#48510).
E2) Place two (2) new cone bearings (#48548LA) in walking
beam bearing tube.
E3) Before installing walking beam assembly c/w new bearings
between wheel leg plates, check the width of these plates.
They must be wider at the bottom than at the top as shown in
Fig. 16. They must not be narrower at the bottom as shown in
Fig. 17.
E4) If wheel leg plates are spaced narrower at the bottom as
shown in Fig. 17, they must be spread apart. To do this,
place a 3/4" x 4" N.C. (19.0mm x 101.6mm) hex bolt c/w nut
between plates as shown in Fig. 15. To force wheel leg plates
apart, unscrew the bolt and nut assembly. Adjust plates so
they are approximately 1/16" (1.5mm) wider at bottom as
shown in Fig. 16.
E5) See Fig. 18. Place bearing tube of walking beam assembly
between wheel leg plates. Place one .135” (3.4mm) machinery
bushing plus one .075” (1.9mm) machinery bushing over each
bearing. Install 1-3/8" (35.0mm) bolt through wheel leg plates
and walking beam bearing tube. Install 1-3/8" (35.0mm)
slotted nut and tighten bolt so the two (2) wheel leg plates are
drawn in so they are parallel 4-1/4” (109.5mm) apart. Do not
draw in plates so they are tipped in at bottom as shown in
ILL. 17.
Next oscillate walking beam up and down and pull side to side.
There should not be any side to side movement. There should
be enough preload on bearing to require approximately 5 lbs of
pressure to oscillate walking axle. If walking beam has side to
side movement or does not have enough preload, remove bolt
and add necessary .045” (1.14mm) machinery bushing(s) to
complete the adjustment.
IMPORTANT: PREMATURE BEARING FAILURE WILL OCCUR IF
WHEEL LEG PLATES ARE NOT PRESSING EVENLY
ALL AROUND BEARINGS.
E6) After adjustments are complete, install cotter pin in slotted
nut.

MAINTENANCE CONTINUED:
CAUTION: LOWER THE CULTIVATOR COMPLETELY TO THE GROUND WHEN SERVICING. IF THE CULTIVATOR MUST BE SERVICED
IN THE RAISED POSITION, INSTALL THE FULL SET OF DEPTH CONTROL SEGMENTS ON THE ROCKSHAFT CYLINDER.
IF THE HYDRAULIC SYSTEM FAILED, OR IF THE HYDRAULIC LEVER WAS ACCIDENTALLY OPERATED, THE AIR DRILL
COULD DROP.
F. Replace any destroyed, missing or illegible decals and
reflectors.
G. See Fig. 19. If center frame castor wheel oscillates (fishtails)
uncontrollably when transporting Air Drill, the spring washers must be
tightened to increase brake pressure. Do this as follows:
g1) Loosen top 1” (25.4mm) jam nut
g2) Tighten bottom 1” (25.4mm) nut until spring washers are fully
compressed.
g3) Loosen bottom 1” (25.4mm) nut 1/6 of a revolution.
g4) Lock bottom nut by tightening top jam nut. It will be necessary
to hold bottom nut while tightening top nut.
H. See Fig. 20. If shank and holder assembly becomes loose so there is
excess side movement, the ¾” I.D. x 3-1/2” (19.0mm x 88.9mm)
long nylon bushing must be replaced. Do this as follows:
h1) Remove ¾” x 5-3/4” (19.0mm x 146.0mm) hex pivot bolt
h2) Using a punch and hammer remove ¾” x 3-1/2” (19.0mm x
88.9mm) long nylon bushing.
h3) Install new nylon bushing into shank holder. Tap in with
hammer.
h4) Re-assemble shank and holder assembly to tower. Install bolt,
lockwashers and nut as shown. Tighten bolt.
h5) Install shank springs and tighten springs as follows after spring
and I-Bolt become snug: (8) turns for Model 3550 Cultivator
(350 lb. trip); (10) turns for Model 5550 Cultivator (550 lb. trip).
I. Wing Lift Cylinder Removal - 4” x 36” (101.6mm x 914.4mm) or 5” x
36” (127.0mm x 914.4mm) cylinder(s) for inner wings. See Fig. 21.
If possible lower wings to field position if wing lift cylinder(s) must be
removed for repair or replacement. If wing lift cylinder(s) must be
removed with wings in folded position, install a safety chain between
each wing frame and main frame to prevent wings from falling down.
Always install a chain on both wings even if only one cylinder is
removed.
CAUTION: IF WING LIFT CYLINDER(S) IS REMOVED WHEN
WINGS ARE FOLDED INTO TRANSPORT POSITION,
ALWAYS INSTALL A SAFETY CHAIN BETWEEN EACH
WING FRAME AND MAIN FRAME TO PREVENT
WING(S) FROM FALLING. IF WING(S) FELL SERIOUS
INJURY OR DEATH COULD OCCUR TO PERSON(S)
NEARBY AND MACHINE WOULD BE DAMAGED SEVERLY.
