SAFETY
WATCH FOR THIS SYMBOL. IT IDENTIFIES IMPORTANT SAFETY MESSAGES. WHEN YOU SEE THIS SYMBOL, READ THE SAFETY
MESSAGE CAREFULLY.
GENERAL SAFETY
1. Never allow anyone to ride on the tractor drawbar, or on the chisel plow. The person(s) riding may fall and be seriously or fatally
injured.
2. Machinery should be operated ONLY by person(s) responsible and qualified to do so.
3. Never allow anyone to climb or play on the tractor or chisel plow. They may fall and be seriously injured.
4. Follow all safety precautions in your tractor 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 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 chisel plow and may cause serious injury to the operator or person(s) nearby.
6. 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.
7. 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.
8. Do not raise or lower the main or wing frames until all components are securely tightened. Loose components will cause serious
damage to the chisel plow and serious injury or death to you and person(s) nearby if the main or wing frames fell.
9. Before applying pressure to the hydraulic system, be sure all connections are tight and the components are not damaged.
Page 1

ASSEMBLY SAFETY CONTINUED:
10. Always wear gloves and eye protection when searching for leaks in the hydraulic system. Use a piece of wood or cardboard as a
backstop against spurting fluid. See a physician immediately if you are injured by hydraulic fluid under pressure.
11. Insure the cylinders are completely filled with oil before connecting the rod ends. If the wing cylinders are not completely filled with
hydraulic oil, the wings may free-fall, causing serious injury to personnel and damage to the chisel plow.
12. All ball joints (which fasten the linkage to the rockshafts) must be kept very tight. The linkage straps are to be drawn up tight against
the ball joints. The ball joint must be free to pivot in the socket. Lubricate the ball joints with oil before installing the linkage. If the
bolts are loose, the linkage, ball joints and bolts will wear, causing excessive slack between the rockshaft making even depth control
difficult.
MAINTENANCE SAFETY
1. Do not disassemble or loosen 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 servicing the hydraulic system.
2. Check all hydraulic hoses periodically for signs of rupture 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 chisel plow 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 chisel plow and serious injury or death to
you or those nearby.
7. Lower the chisel plow to the ground when servicing. If the chisel plow must be serviced in the raised position, engage the rockshaft
lock-up bracket. If the hydraulic system failed, or if the hydraulic lever was accidentally operated, the chisel plow could drop.
8. Do not service or adjust the chisel plow 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 or adjusting the chisel plow. If the tractor and chisel plow were to roll,
you could be seriously or fatally injured.
10. If wing lift cylinder(s) are 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
chisel plow. Check local laws regarding transport regulations.
2. When transporting the chisel plow always lock the rockshaft by installing all depth stop collars on rockshaft cylinder shaft. If the
hydraulic system failed, or if the hydraulic lever was accidentally operated, the chisel plow could drop, resulting in serious damage to
the chisel plow and serious injury or death to you or those nearby.
Page 2

Transport Safety continued:
3. Do not exceed 10 mph (16 km/h) when transporting the chisel plow on smooth surfaces. Reduce your speed on rough surfaces. Do not
transport the chisel plow with any other vehicle except a tractor.
4. When transporting the chisel plow 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 chisel plow.
5. Always attach a safety chain to the tractor drawbar and the chisel plow hitch before transporting the chisel plow. Serious damage and
injury could result from the chisel plow separating from the tractor drawbar.
6. Always lock the wings in the folded position with the transport locks before transporting the chisel plow. Serious damage to the chisel
plow and serious injury or death could result from the wings falling during transport.
7. Check all reflectors for visibility and cleanliness before transporting the chisel plow. It is important that the reflectors are clean and
visible, especially during the evening hours.
8. Regulate your speed on hillsides and curves when transporting the chisel plow. Loss of tractor control could result in serious damage to
the chisel plow and possible serious injury or death to you or those nearby.
9. Never allow anyone to ride on drawbar of the tractor or on the chisel plow. The person riding may fall and be seriously injured.
OPERATION SAFETY
1. Be sure person(s) are standing clear before starting or moving the tractor and chisel plow.
2. Only one (1) person (the operator) should be permitted on the tractor when the chisel plow is in operation, and he/she should be familiar
with repair procedures and temporary first aid treatment.
3. Never stand between the tractor and chisel plow when hitching the chisel plow 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 chisel plow 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.
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. Never allow anyone to ride on the tractor drawbar, or on the chisel plow. The person riding may fall off and be seriously or fatally
injured.
7. Machinery should be operated only by person(s) responsible and qualified to do so.
8. Never allow anyone to climb or play on the chisel plow. They may fall and be seriously injured.
SAFETY DECALS
1. Keep all safety 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.

OPERATION & FIELD ADJUSTMENTS
OPERATION
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 CHISEL PLOW.
IMPORTANT: ONLY ONE (1) PERSON (THE OPERATOR) SHOULD BE PERMITTED ON THE TRACTOR WHEN THE CHISEL PLOW 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 6.
F) Use a tractor speed that will provide the desired cutting action.
IMPORTANT: DO NOT OPERATE THE CHISEL PLOW 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 CHISEL PLOW WHEN HITCHING THE CHISEL PLOW 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 CHISEL PLOW 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 5
DANGER: TO AVOID PERSONAL INJURY OR DEATH,
ALWAYS STAY CLEAR OF THE FOLDING WINGS
WHEN THEY ARE BEING RAISED, LOWERED OR
IN THE FOLDED (UP) POSITION. IF THE
HYDRAULIC SYSTEM FAILED, OR IF THE
HYDRAULIC LEVER WAS ACCIDENTLY
OPERATED, THE WINGS COULD DROP,
RESULTING IN SERIOUS INJURY TO YOU AND
THOSE NEARBY.

2. FIELD ADJUSTMENTS:
A) See Fig. 2. To level chisel plow from front to rear, raise or lower front of chisel plow by adjusting length of castor wheel links, Arrow 2.
In general, when levelling chisel plow from front to rear the wing castor wheels should be adjusted first. Then adjust center section
castor wheel so it is at same height as wing castor wheels. The two (2) wing frame castor wheel assemblies usually carry the front of
chisel plow 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 chisel plow is placed in transport position.
B) When initial levelling adjustments are made, perform the following procedures to check if further adjustments are required:
(C1) Lower chisel plow to ground, close rockshaft cylinder completely raising wheels off ground.
(C2) Raise chisel plow so front center section shovels are approximately 1" off ground.
(C3) Check height of shovels at rear of center section and each wing.
(C4) Adjust linkage as required and repeat section 3.
C) 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 levelling adjusters on wings.
NOTE: Levelling adjusters will be easier to adjust if there is no load on wheels. After adjustments are done be sure to
engage lock adjuster from changing. Levelling adjuster are locked by tightening nut against body of levelling
adjuster.
CAUTION: NEVER STAND BETWEEN THE TRACTOR AND CHISEL PLOW WHEN HITCHING CHISEL PLOW 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.

FIELD ADJUSTMENTS CONTINUED:
E) See Fig. 3. The cutting depth is controlled by installing
segment collars on the rockshaft cylinder shaft. Five
(5) segments varying in length from 1" to 4-1/4" (25.4
to 107.9mm). Install these segments as required.
F) The springs on the shank trip assembly are tightened
seven (7) turns on the eye-bolts after the springs
become snug. If the shank is disassembled, the spring
should be retightened seven (7) turns when
reassembling.
IMPORTANT: BE SURE ALL BOLTS ARE CHECKED PERIODICALLY FOR TIGHTNESS. SPECIAL ATTENTION SHOULD BE GIVEN TO THE 1"
PIVOT BOLTS ON THE SHANK TRIP ASSEMBLIES. IF THE BOLTS COME LOOSE, THE TRIP MOUNT BRACKETS COULD BE
DAMAGED
DANGER: DO NOT STAND UNDER WING WHILE WING IS BEING RAISED OR LOWERED. IF ANY COMPONENTS OF THE
HYDRAULIC SYSTEM SHOULD FAIL, OR IF THE HYDRAULIC LEVER SHOULD ACCIDENTLY BE OPERATED, WING
COULD DROP.

FIELD ADJUSTMENTS CONTINUED:
G) See Fig. 4. Install the "SMV" emblem (not supplied by
Ezee-On) in the "SMV" bracket bolted to the rear
rockshaft bearing on center frame before transporting the
chisel plow.
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
CHISEL PLOW OVER PUBLIC ROADS.
CHECK LOCAL LAWS REGARDING
TRANSPORT REGULATIONS.
H) See Fig. 5. Install the transport lock pins to lock the
wings in the folded position before transporting the chisel
plow. See the illustration at the right.
CAUTION: ALWAYS LOCK THE WINGS IN THE
FOLDED POSITION WITH THE
TRANSPORT LOCKS BEFORE
TRANSPORTING THE CHISEL PLOW.
SERIOUS DAMAGE TO THE CHISEL PLOW
AND SERIOUS INJURY OR DEATH COULD
RESULT FROM THE WINGS FALLING
DURING TRANSPORT.
I) See Fig. 6. Attach a safety chain (with a strength rating
greater than the gross weight of the towed chisel plow) to
the tractor drawbar and the chisel plow hitch before
transporting the chisel plow. See the illustration at the
right.
CAUTION: ALWAYS ATTACH A SAFETY CHAIN TO
THE TRACTOR DRAWBAR AND THE
CHISEL PLOW HITCH BEFORE
TRANSPORTING THE CHISEL PLOW.
SERIOUS DAMAGE TO THE CHISEL PLOW
AND SERIOUS INJURY OR DEATH COULD
RESULT FROM THE CHISEL PLOW
SEPARATING FROM THE TRACTOR
DRAWBAR.

FIELD ADJUSTMENTS CONTINUED:
J) Fig. 7. Install all depth control segment (11-1/4" Lg) on cylinder
shaft before transporting the chisel plow. See the illustration at
the right.
CAUTION:BEFORE TRANSPORTING THE CHISEL PLOW
ALWAYS LOCK THE ROCKSHAFT BY IN STALLING
ALL THE DEPTH CONTROL SEGMENT (11-1/4"
LG). IF THE HYDRAULIC SYSTEM FAILED, OR IF
THE HYDRAULIC LEVER WAS ACCIDENTLY
OPERATED THE CHISEL PLOW COULD DROP,
CAUSING SERIOUS INJURY OR DEATH TO YOU OR
THOSE NEARBY.
K) See Fig. 8. If cultivating conditions are extreme and wing
flexibility is necessary, remove the pins from the rod ends of the
wing lift cylinders and retract the cylinders (shown in dashed lines
at the right). Lay the retracted cylinders on the frame.
When reattaching the wing lift cylinders to the cylinder lugs on the
wing frames, be sure to block up the cylinder to allow the shaft
end to pass over the cylinder lug.
IMPORTANT: IF THE CYLINDER IS NOT BLOCKED UP, THE SHAFT
END MAY STRIKE THE CYLINDER LUG, CAUSING
SERIOUS DAMAGE TO THE CYLINDER.
CAUTION: USE EXTRA CARE WHEN OPERATING THE CHISEL PLOW 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.
CAUTION: NEVER ALLOW ANYONE TO RIDE ON THE TRACTOR DRAWBAR, OR ON THE CHISEL PLOW. THE PERSON RIDING MAY
FALL OFF AND BE SERIOUSLY OR FATALLY INJURED.
CAUTION: MACHINERY SHOULD BE OPERATED ONLY BY PERSON(S) RESPONSIBLE AND QUALIFIED TO DO.
CAUTION: NEVER ALLOW ANYONE TO CLIMB OR PLAY ON THE CHISEL PLOW. THEY MAY FALL AND BE SERIOUSLY INJURED.

FIELD OPERATIONS CONTINUED:
Rear Tow Hitch Adjustment – Tow Hitch is available as an Option
L1) See Fig. 9. When towing equipment such as Model 160 2 wheel air seeder behind Model 7450 Chisel Plow, the air seeder
hitch must be attached low enough so the air seeder hitch slopes down towards the chisel plow at about a 5 degree angle.
*(Ezee-On and Dutch Air Seeders with 2 wheels will have hitch sloped up towards tow hitch, however the hitch must still be
attached low to obtain a balanced line of draft).
L2) If an air seeder hitch is attached too high it will pull rear of chisel plow down causing uneven shank penetration.
L3) If tow hitch other than Ezee-On is used, it may have to be modified so towed equipment can be hitched lower.
CAUTION: DO NOT EXCEED 10 MPH (16 KM/H) WHEN TRANSPORTING THE CHISEL PLOW ON SMOOTH SURFACES. REDUCE
YOUR SPEED ON ROUGH SURFACES. DO NOT TRANSPORT THE CHISEL PLOW WITH ANY OTHER VEHICLE EXCEPT
A TRACTOR.
DANGER: WHEN TRANSPORTING THE CHISEL PLOW 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 CHISEL PLOW.

PINS: operation.
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
ROCKSHAFT CYLINDER SHAFT. THEN LOWER CULTIVATOR UNTIL CYLINDER HITS DEPTH SEGMENTS. IF
THE HYDRAULIC SYSTEM FAILED, OR IF THE HYDRAULIC LEVER WAS ACCIDENTLY OPERATED, THE
CULTIVATOR COULD DROP.
CAUTION: DO NOT LUBRICATE THE CULTIVATOR WHEN IT IS IN MOTION. YOU MAY FALL AND BE SERIOUSLY OR
FATALLY INJURED.
Page 12

LUBRICATION CONTINUED: (SECTION 1)
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 – 150 ft. lbs. (203 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 4 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. 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.
Page 13
C) See Fig. 11. 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.
4. MAINTENANCE
A) All bolts and nuts should be checked periodically to make sure they
are tight. Special attention should be given to the 1" (25.4mm) pivot
bolt on the shank trip assembly. If this pivot bolt comes loose, the
trip mount bracket could be damaged.

MAINTENANCE CONTINUED: (SECTION 2)
E) Replacing Walking Beam Bearings - See Fig. 12, 13, 14 and 15.
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. 13. They must not be narrower at the bottom as shown in
Fig. 14.
E4) If wheel leg plates are spaced narrower at the bottom as
shown in Fig. 18, 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. 16. 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. 13.
E5) See Fig. 15. 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. 14.
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.

FIG. 17
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. 16. 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. 17. 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 1” x 7-1/2” (25.4mm x 190.5mm) hex pivot bolt
h2) Using a punch and hammer remove 1” x 5” (25.4mm x
127mm) 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.
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.
22. 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.
