SAFETY RECOMMENDATIONS
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 disc. The person(s) riding may fall and be seriously or fatally injured.
2. Disc should be operated ONLY by persons responsible and qualified to do so.
3. Never allow anyone to climb or play on the tractor or disc. 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. When assembling disc, use aligning punch to line up holes. Keep fingers out of holes. Any sudden movement of heavy components
will severely injure or sever your fingers.
2. Use adequate manpower or hoist to lift the heavy components into place. 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 or person(s) nearby.
5. Be sure all wheel bolts are checked for tightness during initial transport or when first discing. Loose wheel bolts may result in the
wheel falling off, causing serious damage to the disc and may cause serious injury to the operator or person(s) nearby.
6. To fill the wing lift cylinder 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 wing will free-fall if the cylinder
is not completely filled with fluid, resulting in serious damage to machine or serious injury or death to person(s) nearby.
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 disc and serious injury or death to you and person(s) nearby if the main or wing frames fell causing serious injury or
death.
8. Hydraulic oil escaping under pressure has sufficient force to cause serious injury. Relieve pressure in all hydraulic components before
disconnecting any hydraulic components. Before applying pressure to hydraulic system, be sure all connections are tight and
components are not damaged. If injured by escaping hydraulic fluid, see a medical doctor immediately.
9. When attaching gang assemblies, wear protective gloves to prevent injury from cutting edges of blades.
10. Before applying pressure to the hydraulic system, be sure all connections are tight and the components are not damaged.
11. Wing will free fall if wing cylinder is not full of oil causing serious damage to machine or serious injury or death to person(s) nearby.
12. If hydraulic cylinder shafts are unpinned and cycled to fill the cylinders with oil, they can be seriously damaged if clevis of shaft
strikes rockshaft arm or wing cylinder lug.

Page 3
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. If injured by escaping hydraulic fluid, see a
medical doctor immediately.
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 disc 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. To fill wing lift cylinder with hydraulic oil, extend and contract cylinder within slot on wing until cylinders are completely filled with
oil. Do not fold wing until cylinder is completely filled, wing(s) will free fall if cylinders are not filled with oil, causing serious damage
to machine or serious injury or death to person(s) nearby.
7. Lower the disc to the ground when servicing or making adjustments. If the disc must be serviced in the raised position, place blocks
under frame. Do not rely on hydraulics lock up valves as a safety device. If the hydraulic system failed, or if the hydraulic lever was
accidentally operated, the disc could drop.
8. Do not lubricate disc while it is in motion. You may fall in front of disc and be seriously or fatally injured.
9. Always place all tractor controls in neutral and lock
brakes when hitching disc to tractor. Tractor could roll
backwards when hitching disc.
10. If wing lift cylinder is removed when wing is folded into transport position, always install a safety chain between 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 severely.
TRANSPORT SAFETY
1. When trailing the disc over public roads, use the SMV emblem and warning light for protection of tractor and other motor vehicle
operators. Check local laws for width and height maximums.
2. When transporting disc always place both hydraulic lock up valves in “closed” position. See Section 7 of Operating Instructions on
page 6. If hydraulic lever was accidentally operated the disc could drop or wing could fall.
3. Do not exceed 10 mph (16 km/h) when transporting the disc on smooth surfaces. Reduce speed when transporting on rough surfaces.
Excessive speed could cause loss of tractor control and damage to disc and tractor. Do not transport the disc with any other vehicle
except a tractor.
4. When transporting the disc with the wing(s) 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 disc.
5. Always attach a safety chain to the tractor drawbar and
the disc hitch before transporting the disc. Serious
damage and injury could result from the disc separating
from the tractor drawbar.

Page 4
TRANSPORT SAFETY CONTINUED:
6. Check all reflectors and visibility and cleanliness before transporting the disc. It is important that the reflectors are clean and visible,
especially during the evening hours.
7. Regulate your speed on hillsides and curves when
transporting the disc. Loss of tractor control could result
in serious damage to the disc and possible serious injury
or death to you or those nearby.
8. Never allow anyone to ride on drawbar of the tractor or on the disc. The person riding may fall and be seriously injured.
9. When transporting disc always install the complete package of depth control stops 17" (432 mm) long on shaft of main framecylinder.
If any components of hydraulic system failed disc could drop causing serious injury or death to operator or person(s) nearby.
OPERATION SAFETY
1. Be sure person(s) are standing clear before starting or moving the tractor and disc.
2. Only one (1) person (the operator) should be permitted on the tractor when the disc is in operation, and he/she should be familiar
with repair procedures and temporary first aid treatment.
3. Never stand between the tractor and disc when hitching disc 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 persons nearby.
4. When operating on hillsides, use extreme care. The tractor may tip over if it strikes a hole, ditch or other irregularity.
5. To avoid personal injury or death, always stay clear of the folding wing(s) when it is being raised, lowered or in the folded position.
If the hydraulic system failed, or if the hydraulic lever was accidentally operated, the wing could drop, resulting in serious injury or
death to you or those nearby.
6. Do not stand under wing while wing is being raised or lowered. If any components of hydraulic system should fail, or if hydraulic lever
should accidentally be operated, wing could drop causing serious injury or death.
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.

GENERAL OPERATION
1. Before operating disc, refer to Safety Precautions on pages 2 to 4. Review disc safety items applicable to road transport and field
operation of disc.
2. IMPORTANT: WHEN LOWERING WING TO FIELD POSITION, BE SURE WING LIFT CYLINDER IS FULLY EXTENDED. AFTER WING TIRES
HAVE HIT THE GROUND CONTINUE TO HOLD HYDRAULIC LEVER. THERE WILL BE A SHORT PAUSE BEFORE CYLINDERS
FULLY EXTEND. IF CYLINDER IS NOT FULLY EXTENDED, THE WING WILL HANG ON CYLINDERS AND WILL NOT FLEX
DOWN.
CAUTION: NEVER STAND BETWEEN THE TRACTOR AND DISC WHEN HITCHING DISC 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 PERSONS NEARBY.
3. For best performance, the tractor drawbar should be pinned at centre of tractor.
4. Ensure disc is level and cutting depth is properly adjusted. If further adjustments are required, see pages 10 to 15.
5. Do not make sharp turns with the disc in ground. Sharp turns put excess pressure on the gangs.
IT IS ADVISABLE TO ALWAYS LIFT MACHINERY OUT OF GROUND FOR MAKING SHARP TURNS. EXCESSIVE SIDE THRUST IS APPLIED
TO BEARINGS AND MACHINE IF DISC IS TURNED WHILE IT IS IN THE GROUND.
6. In discing conditions where extreme wing flexibility is required, remove cylinder pin from shaft end of wing lift cylinder and retract
cylinder.
7. See Fig. 1. When transporting disc, always place
hydraulic lockup valves in closed position. Lock up
valves are located at the front end of centre frame.
CAUTION: WHEN TRANSPORTING DISC ALWAYS
PLACE BOTH HYDRAULIC LOCK UP
VALVES IN “CLOSED” POSITION. IF
HYDRAULIC LEVER WAS ACCIDENTALLY
OPERATED THE DISC COULD DROP OR
WING COULD FALL.
8. See Fig. 2. When transporting disc always place the
complete depth control package 17" (432 mm) long on
shaft of 3-1/2" x 24" (88.9 mm x 610 mm) main frame
lift cylinder.
CAUTION: WHEN TRANSPORTING DISC ALWAYS
INSTALL THE COMPLETE PACKAGE OF
DEPTH CONTROL STOPS 17" (432 mm)
LONG ON SHAFT OF MAIN FRAME
CYLINDER. IF ANY COMPONENT OR
HYDRAULIC SYSTEM FAILED DISC
COULD DROP CAUSING SERIOUS
INJURY OR DEATH TO OPERATOR OR
PERSON(S) NEARBY.
9. IMPORTANT: WHEN TRANSPORTING DISC, DO NOT EXCEED SPEED OF 10 MPH (16 KM/H).
10. IMPORTANT: DO NOT DISC WITH FRONT GANGS CUTTING DEEPER THAN REAR GANGS. DISC MUST BE LEVEL. IF FRONT GANGS
ARE LOWER, EXCESSIVE STRAIN WILL BE PLACED ON BLADES, GANG BEARINGS AND FRAME HITCH, WHICH COULD
LEAD TO PREMATURE PARTS FAILURE, ESPECIALLY OUTSIDE BLADES OF FRONT GANGS.
11. IMPORTANT: WHEN DISC IS PARKED WITH BLADES RESTING ON FROZEN GROUND, DO NOT ATTEMPT TO LIFT DISC OUT OF FROZEN
GROUND BY LOWERING TRANSPORT WHEELS. LIFTING DISC OUT OF FROZEN GROUND WITH TRANSPORT WHEELS
MAY CAUSE SERIOUS DAMAGE TO DISC COMPONENTS. DAMAGE WILL MOST LIKELY OCCUR TO MAIN LIFT CYLINDERS
AND ROCKSHAFT CYLINDER ARMS. DO NOT PARK DISC WITH BLADES ON GROUND THAT MAY FREEZE. LEAVE DISC
PARKED ON TRANSPORT WHEELS.

Page 7
GENERAL OPERATING INSTRUCTIONS CONTINUED:
12. IMPORTANT: TO AVOID SERIOUS DAMAGE TO HITCH JACK, BE SURE JACK IS LOCKED IN HORIZONTAL POSITION AND CRANK OF
JACK IS NOT HANGING BELOW HITCH WHEN DISC IS IN MOTION. SEE PAGE 22 SECTION 17.
13. IMPORTANT: DO NOT OPERATE DISC IN FIELD WITH WING FOLDED INTRANSPORT POSITION. SEVERE DAMAGE WILL OCCUR WHEN
DISCING WITH WINGS FOLDED.
CAUTION: DO NOT STAND UNDER WING WHILE WING IS BEING RAISED OR LOWERED. IF ANY COMPONENTS SHOULD FAIL,
OR IF HYDRAULIC LEVER SHOULD ACCIDENTALLY BE OPERATED, WING COULD
14. To keep disc level transport wheels must be riding on ground gauging desired discing depth, as shown in Fig. 4.
If conditions are such that disc can not penetrate to maximum depth, do not raise transport wheels off ground as shown in Fig. 3.
Raised transport wheels may cause front of disc to drop causing front gangs to cut deeper than rear gangs.
Front of disc may drop because rockshaft and hitch levelling arm is linked. As the wheels are raised, the hitch levelling arm is pulled
back allowing hitch to float. If hitch is allowed to float it will not support front of disc allowing front gang to drop.
With front of disc lower than the rear, the front outside blades will cut much deeper than the front inside blades. This means that
more of the disc's weight is placed on the front outside blades, forcing them deeper into the ground.
Uneven and deep front gang penetration in tough conditions will place excessive strain on blades, gang bearings, frame and hitch,
and will lead to a premature failure of parts especially outside blades and bearings of front gangs.
The condition shown in Fig. 3 may also cause frame to buckle upward at frame hinge point, raising centre blades off ground. If frame
is level, as shown in Fig. 4 thrust at outside end of front gangs is greatly reduced. Side thrust is distributed evenly on all front blades,
reducing the possibility of centre rising.
IMPORTANT: OPERATING DISC WITH TRANSPORT WHEELS OFF GROUND WILL CAUSE UNEVEN DISCING JOB AND PLACE UNDUE
STRAIN ON MACHINE WHICH COULD LEAD TO PARTS FAILURE. ALWAYS OPERATE DISC WITH TRANSPORT WHEELS ON
GROUND EVEN IF SOIL CONDITIONS WILL NOT ALLOW DISC TO PENETRATE TO MAXIMUM DEPTH.

Page 8
GENERAL OPERATION CONTINUED:
15. See Fig. 5. Attach a safety chain to the tractor drawbar and to
the disc's hitch before transporting the disc. Use a chain with
strength rating greater than the gross weight of disc.
(Safety chain available as an option).
CAUTION: WHEN TRANSPORTING A DISC, BE SURE TO
ATTACH A SAFETY CHAIN TO TRACTOR DRAWBAR
AND DISC HITCH. THE SAFETY CHAIN WILL HELP
CONTROL DISC SHOULD IT ACCIDENTALLY
SEPARATE FROM THE DRAWBAR. USE A CHAIN
WITH A STRENGTH RATING GREATER THAN THE
GROSS WEIGHT OF THE TOWED MACHINE.
SERIOUS DAMAGE, INJURY OR DEATH COULD
RESULT FROM THE DISC SEPARATING FROM
THE TRACTOR DRAWBAR.
CAUTION: DO NOT STAND UNDER THE WING WHILE IT IS
BEING RAISED OR LOWERED. IF ANY COMPONENT
OF THE HYDRAULIC SYSTEM FAILED OR IF THE
HYDRAULIC LEVER WAS ACCIDENTALLY
OPERATED, WING COULD FALL CAUSING SERIOUS
INJURY OR DEATH.
16. See Fig. 7. Install the “SMV” Emblem (not supplied by
Ezee-On) in the “SMV” bracket welded to the rear of main frame
before transporting disc.
CAUTION: USE THE “SMV” EMBLEM (NOT SUPPLIED BY
EZEE-ON) AND WARNING LIGHTS FOR THE
PROTECTION OF TRACTOR AND OTHER VEHICLE
OPERATIONS WHEN TRANSPORTING THE DISC
OVER PUBLIC ROADS. CHECK LOCAL LAWS
REGARDING TRANSPORTING REGULATIONS.
CAUTION: WHEN OPERATION ON HILLSIDES, USE EXTRA CARE. TRACTOR MAY TIP SIDEWAYS IF IT STRIKES A HOLE, DITCH
OR OTHER IRREGULARITIES.

Page 9
GENERAL OPERATION CONTINUED:
CAUTION: WHEN TRAILING THE DISC OVER PUBLIC ROADS, USE THE SMV EMBLEM AND WARNING LIGHTS FOR PROTECTION
OF TRACTOR AND OTHER MOTOR VEHICLE OPERATORS. CHECK LOCAL LAWS FOR WIDTH AND WEIGHT MAXIMUMS
AND HEIGHT MAXIMUMS.
CAUTION: DO NOT EXCEED 10 mph (16 km/h) WHEN TRANSPORTING DISC ON SMOOTH ROADS, REDUCE SPEED WHEN
TRANSPORTING ON ROUGH ROADS. EXCESSIVE SPEED COULD CAUSE LOSS OF TRACTOR CONTROL AND DAMAGE
TO DISC AND TRACTOR. DO NOT TRANSPORT DISC WITH ANY OTHER VEHICLE EXCEPT TRACTOR.
DANGER: WHEN TRANSPORTING DISC WITH WING RAISED, 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 DISC.
WARNING: WHEN TRANSPORTING DISC, ALWAYS PLACE HYDRAULIC LOCK UP VALVE IN “CLOSED” POSITION. SEE SECTION
8 OF OPERATING INSTRUCTIONS ON PAGE 6. IF THE HYDRAULIC LEVER WAS ACCIDENTALLY OPERATED, THE DISC
COULD DROP CAUSING SERIOUS INJURY TO OPERATOR.
17. REPHASING ROCKSHAFT CYLINDERS - Periodically, the hydraulic lift cylinder on wing frame will not be synchronized with main frame
cylinder. This will cause uneven cutting depth. If this happens it will be necessary to rephase the lift cylinders. Rephasing is done
by lifting disc completely out of the ground and holding the hydraulic control lever until both (2) rockshaft cylinders are fully
extended. See section 30 on page 29 for further information on the lift hydraulic system.
WARNING: NEVER ALLOW ANYONE TO RIDE ON DRAWBAR OF THE TRACTOR OR ON THE DISC. THE PERSON RIDING MAY FALL
AND BE SERIOUSLY INJURED.
WARNING: LOWER THE DISC TO THE GROUND WHEN SERVICING OR MAKING ADJUSTMENTS . IF THE DISC MUST BE SERVICED
OR ADJUSTED IN THE RAISED POSITION, PLACE BLOCK UNDER FRAME. DO NOT RELY ON HYDRAULIC LOCK UP
VALVES AS A SAFETY DEVICE. IF THE HYDRAULIC SYSTEM FAILED, OR IF THE HYDRAULIC LEVER WAS
ACCIDENTALLY OPERATED, THE DISC COULD DROP.
18. IMPORTANT: BEFORE DISCONNECTING HYDRAULIC HOSES FROM TRACTOR, RELIEVE PRESSURE IN HYDRAULIC CYLINDERS,
SERIOUS DAMAGE COULD OCCUR TO HYDRAULIC CYLINDERS IF OIL EXPANSION TAKES PLACE DUE TO WARM
WEATHER OR IF DISC IS STORED IN HEATED BUILDING.
19. IMPORTANT: IN DISCING CONDITIONS WHERE EXTREME WING FLEXIBILITY IS REQUIRED, REMOVE CYLINDER PIN FROM SHAFT
END OF WING LIFT CYLINDER AND RETRACT CYLINDERS.
WHEN REATTACHING SHAFT END OF WING LIFT CYLINDER TO WING FRAME, BE SURE CYLINDER SHAFT DOES NOT
STRIKE CYLINDER LUG ON WING FRAME. SERIOUS DAMAGE MAY OCCUR TO CYLINDER IF CYLINDER SHAFTSTRIKES
CYLINDER LUG. BEFORE EXTENDING CYLINDER SHAFT BLOCK UP CYLINDER SO THAT CYLINDER SHAFT PASSES
OVER CYLINDER LUGS.

ADJUSTMENTS
1. SETTING ANGLE OF FRONT AND REAR GANGS - See Fig. 8
NOTE: Gang angle adjustments are made on outside of frame.
a) The angle the gangs are set at is determined by the soil conditions. A field with hard soil will require more cutting angle to penetrate
soil than a field with soft soil. In soft soil conditions, disc will push dirt or ridge at outside if there is too much cutting angle. To start,
the minium angle is recommended.
IMPORTANT: EXCESSIVE GANG ANGLE WILL PUT ADDED PRESSURE ON THE GANGS AND WILL DECREASE THE LIFE OF
BEARINGS, BLADES, ETC. WHEN GANGS ARE SET AT AN EXTREME ANGLE, MORE HORSEPOWER IS REQUIRED TO
PULL DISC.
IMPORTANT: WHEN SETTING GANG ANGLE BE SURE TO SET THE FRONT WING GANG AT SAME ANGLE AS THE FRONT MAIN
FRAME GANG. THE REAR WING GANG MUST BE SET AT SAME ANGLE AS REAR MAIN FRAME GANG. FOR
EXAMPLE, IF FRONT WING GANG IS AT THIRD HOLE FROM FRONT, THEN SET FRONT MAIN GANG AT THIRD HOLE
FRONT.
CAUTION: WHEN OPERATING ON HILLSIDES USE EXTREME CARE. TRACTOR MAY TIP SIDEWAYS IF IT STRIKES HOLE,
DITCH OR OTHER IRREGULARITY.

Page 11
ADJUSTMENTS CONTINUED:
b) ADJUSTING FRONT GANG ANGLE - See Fig. 8. Loosen inner clamp plate, arrow 3, which fastens gang beam to inner bracket, arrow
2. Remove outer clamp plate, arrow 4, which fastens gang beam to outer bracket, arrow 1. The gang angle is set by fastening rear
bolt of clamp plate, arrow 4, to holes “A” or “B” of outer bracket. If minimum angle is desired, select hole “A” and if maximum angle
is desired, select hole “B”, see Table y. After choosing gang angle, install clamp plate to outer bracket, arrow 2, with (2) 1-1/4" x
7-1/2" (31.75 mm x 190.5 mm) hex bolts c/w nuts and washers.
c) ADJUSTING REAR GANG ANGLE - See Fig. 8. Loosen inner clamp plate, arrow 6, which fastening gang beam to inner bracket, arrow
7. Remove outer clamp plate, arrow 5, which fastens gang beam to outer bracket, arrow 8. The gang angle is set by fastening rear
bolt of clamp plate, arrow 5, to hole “C” or “D” of outer bracket. If minimum angle is desired, select hole “D” and if maximum angle
is required select hole “C”, see Table y. After choosing gang angle, install clamp plate to outer bracket, arrow 8, with (2)
1-1/4" x 7-1/2" ( 31.75 mm x 190.5 mm) hex bolts c/w nuts and washers.
NOTE: Above instructions along with Fig. 8 describes how to adjust gang angle of main frame gangs. Adjust wing gangs
using the same method. Main frame gangs and wing gangs must be set at same angle.
2. LATERAL ADJUSTMENT OF THE FRONT AND REAR GANGS
A) FRONT GANGS - See Fig. 8. Loosen gang beam clamp plates, arrow 3 and 4. Next, adjust front gangs so that leading edge
of inside blades, arrow 3, are approximately 2-1/2" (63.5 mm) past centre of disc. The centre of disc is shown in Fig. 8. If
the above adjustment is made correctly, the front gangs will not leave any unbroken ground at centre of disc.
B) REAR GANGS - See Fig. 8. Loosen beam clamps, arrow 5 and 6. The opening between the rear gangs, dimensions "D", must
be set at a distance that will allow furrow left by the front gangs to be filled evenly. The distance the rear gangs are set apart
is determined by the discing speed, discing depth, gang angle and soil conditions. If the rear gangs are set too close together,
the rear gangs will leave a ridge at centre. If rear gangs are set too far apart, the furrow at centre left by the front gangs will
not be filled. Take note of the amount of soil the rear inside blades are picking up. It may be necessary to increase distance
between rear gangs in order to collect enough soil to fill furrow.
To start with this distance should be set at 2" (51 mm) less than diameter of blades. For example, if your machine is
equipped with 24" blades, then the opening (Dimension “D”) should be 22" (559 mm).
An increase in discing speed may required rear gangs to be set further apart. A decrease in discing speed may require rear
gangs to be set closer together.
3. IMPORTANT: See Fig. 8. When gang adjustments are complete, tighten all gang beam clamp plates, arrows 3, 4, 5 and 6 to
840 ft. lbs. (116 m. kgs.)
4. LEVELLING DISC - Front to Rear - See Fig. 9
When discing the front and rear gangs should be cutting at same
depth, the levelling crank, arrow 1, is used to level disc.
To Lower Front Gangs - turn crank, arrow 1, “IN” (clockwise)
To Raise Front Gangs - turn crank, arrow 1, “OUT” (counter
clockwise)
VERY IMPORTANT: Always keep disc level from front to rear.
Discing with front gangs lower than rear
gangs will cause ridging at outside and may
cause damage to disc components.

Page 12
ADJUSTMENTS CONTINUED:
5. SETTING DISCING DEPTH - See Fig. 9.
To set discing depth, install depth control segments, arrow 2, on shaft of main frame cylinder, arrow 3. Install segments as required
to obtain desired discing depth.
6. LEVELLING WING FRAME - See Fig. 10
For even blade penetration, outside of wing frame must
be level with main frame or even 1/2" (12.7 mm) higher
than main frame.
To level wing frame with main frame, adjust wing
rockshaft cylinder I-bolt, arrow 1. If outside of wing
frame needs to be raised, loosen rear nut of y-bolt and
tighten front nut. This will lower the wheels raising
outside of wing. If outside of wing frame needs to be
lowered, loosen front nut of y-bolt and tighten rear nut.
This will raise the wheels allowing outside of wing to
lower.
Before this adjustment is made, be sure centre frame is
level from front to rear. After adjustments are complete
tighten nuts on cylinder y-bolt.
IMPORTANT: BE SURE BARREL OF CLEVIS PIN IS HORIZONTAL WITH CYLINDER PORTS ARE FACING UP. IF CLEVIS PIN IS NOT
HORIZONTAL, CYLINDER WILL NOT BE FREE TO PIVOT UP AND DOWN WHEN IT IS EXTENDED OR CONTRACTED
CAUSING SERIOUS DAMAGE.
7. REMOVE RIDGE AT CENTRE OF DISC - Make one or more of the following adjustments:
a) Level disc from front to rear using levelling crank, see section 4 of adjustments.
b) Reducing discing speeds.
c) Increasing distance between rear gangs, see section 2 of adjustments.
8. REMOVE FURROW AT CENTRE OF DISC - Make one or more of the following adjustments:
a) Level disc from front to rear using levelling crank, see section 4 of adjustments.
b) Increase discing speed.
c) Decrease distance between rear gangs, see section 2 of adjustments.
9. REMOVE UNBROKEN GROUND LEFT BY FRONT GANGS - Make the following adjustment:
a) Adjust leading edge of inside blade of each front gang so it is 2-1/2" (63.5 mm) past centre of disc, see section 2 of adjustments.

Page 13
ADJUSTMENTS CONTINUED:
10. REDUCE SIDE DRAFTING TO ONE SIDE - Check Following Setting:
a) Gang angle setting for right hand gangs must be set same as left hand gangs.
11. REDUCE GANG PLUGGING - Make one or more of the following adjustments:
a) Adjust scrapers so they contact blades.
b) Reduce gang angle if soil conditions are loose causing disc to push soil.
IMPORTANT: DO NOT LOWER FRONT GANGS SO THAT DISC WILL CUT INTO TOUGH CONDITIONS. IF FRONT GANGS ARE
LOWERED, EXCESSIVE STRAIN WILL BE PLACE ON FRONT GANGS, FRAME, AND HITCH, WHICH COULD LEAD TO
PREMATURE PARTS FAILURE, ESPECIALLY OUTSIDE BLADES OF FRONT GANGS.
12. STOP DISC FROM BUCKLING UP CAUSING CENTRE BLADES TO RISE OUT OF GROUND - Make one or more of the following
adjustments:
a) If front gangs are cutting deeper at outside - raise front of disc with levelling crank.
b) Check if transport wheels are raised off ground causing front of disc to drop. If so lower wheel so they ride on ground when
discing, see section 14 on page 7.
c) Check if outer blades on wing are cutting deeper then outer blades of main frame. If so, raise outside of wing by adjusting
anchor bolt fro wing rockshaft cylinder, see section 6 on page 12.
NOTE: The condition described in section 12 may occur if front gangs are lowered so disc will cut into tough
conditions.

MAINTENANCE
1. LUBRICATION See Fig. 11- Grease all lubricating points on disc are marked with arrow G. The oil lubrication points are marked with arrow O.
G1) GANG BEARINGS - for 211 or 410 Series - Lubricate every 20 hours of operation with a minimum amount of grease. Excess lubrication
may damage seals. Use a high quality SAE multipurpose grease.
- for T2-215 Series - Lubricate every 20 hours of operation. Lubricate until grease comes out around seal, excess
lubrication will not damage seal. Use high quality SAE multipurpose grease.
CAUTION: FOR 211 OR 410 SERIES BEARINGS - IF GANG BEARINGS ARE OVER LUBRICATED, THERE IS A POSSIBILITY THAT THE SEALS
CAN BE PUSHED OUT. THIS IS MORE LIKELY TO HAPPEN WHEN BEARINGS ARE NEW.
NOTE: When you receive your new disc, grease all lubricating points before starting to disc. However, use caution when
lubricating 211 or 410 series gang bearings. These gang bearings are filled with grease at factory and seals may be
damaged if over lubricated.
G2) Lubricate wing pivot points with grease every 50 hours of operation.
G3) Lubricate levelling crank with grease every 100 hours of operation.
G4) Lubricate wheels with grease every 50 hours of operation.
G5) Lubricate top and bottom half of each rockshaft bearing every 20 hours of operation. If rockshaft bearings are not lubricated, there will be
excessive wearing of rockshaft and rockshaft bearings.
O1) Lubricate levelling crank ball joints (with oil) at the end and beginning of each season.
O2) Lubricate rockshaft cylinder pins (with oil) every 50 hours of operation.
2. All bolts and nuts should be checked periodically to make sure they are tight. Special attention should be given to gang bolts, bearing bolts
and bearing hanger U-bolts, and wheel bolts. If gang bolts come loose, they must be tightened to 3200 ft. lbs.
They should be tightened as follows:
SGang bolts - 1-15/16" (49 mm) Diameter - 3200 ft. lbs (4336 N.m) torque
SGang beam bolts - 1-1/4" (31.7 mm) Diameter - 840 ft. lbs (1138.2 N.m) torque (minimum/maximum)
SLevelling crank bolt - 1-1/4" (31.7 mm) Diameter - 840 ft. lbs (1138.2 N.m) torque(minimum/maximum)
SWheel bolts - 9/16" (14.2 mm) Diameter - 130 ft. lbs (176.2 N.m) torque
SBearing hanger U-bolts - 3/4" (19 mm) Diameter - 260 ft. lbs (352.3 N.m) torque (Model 4290 only with stone flex hangers)
SBearing hanger U-bolts 5/8" (15.7 mm) Diameter - 150 ft. lbs (203.25 N.m) torque (Model 4290 only with solid hangers)
SBearing hanger U-bolts 7/8" (22 mm) Diameter - 430 ft. lbs (582.65 N.m) torque (Model 4300 only)
Note: Gangs bolts should be re-tightened after 2 hrs of operation.
IMPORTANT!!!
SEVERE DAMAGE WILL OCCUR IF GANG BOLTS ARE LOOSE.
3. When storing disc for a long period of time, grease all lubricating points.
4. Ensure tires are properly inflated. See specifications on page 5 for tire pressures.
5. IMPORTANT: SEE FIG. 12. FOR DISCS EQUIPPED WITH T2-215 BEARINGS. IF T2-215 BEARING IS DISMANTLED, DOUBLE SET SCREWS MUST
BE REMOVED FROM BOTTOM OF HOUSING TO REMOVE CAP.
CAUTION: DO NOT SERVICE DISC WHILE IT IS IN MOTION. YOU MAY FALL IN FRONT OF DISC AND BE SERIOUSLY INJURED.
CAUTION: LOWER THE DISC TO THE GROUND WHEN SERVICING OR MAKING ADJUSTMENTS. IF THE DISC MUST BE SERVICED OR
ADJUSTED IN THE RAISED POSITION, PLACE BLOCKS UNDER FRAME. DO NOT RELY ON HYDRAULIC LOCK UP VALVES AS A
SAFETY DEVICE. IF THE HYDRAULIC SYSTEM FAILED, THE DISC WOULD DROP.
6. See ILL. 12. When reinstalling bearing hanger on T2-215 Bearing (if gangs are dismantled) do not over tighten the 5/8" x 10" (15.7 mm x 254
mm) bolts which fastens hanger to bearing. Secure nut by using a jam nut.

MAINTENANCE CONTINUED:
7. WING LIFT CYLINDER REMOVAL - See Fig. 13. If possible lower
wing to field position if wing lift cylinder must be removed for
repair or replacement. This machine uses a hydraulic lock out
valve as a safety device to lock wing in transport position.
Removing wing lift cylinder leaves machine without a safety
lock. If wing lift cylinder must be removed with wing in folded
position, install a safety chain between wing frame and main
frame to prevent wing from falling down.
Fig. 13
CAUTION: IF WING LIFT CYLINDER IS REMOVED WHEN WING IS FOLDED INTO TRANSPORT POSITION, ALWAYS INSTALL A SAFETY CHAIN
BETWEEN WING FRAME AND MAIN FRAME TO PREVENT WING FROM FALLING. IF WING FELL SERIOUS INJURY OR DEATH
COULD OCCUR TO PERSON(S) NEARBY AND MACHINE WOULD BE DAMAGED SEVERELY.
8. Keep all safety decals clean and in good condition to provide a constant reminder of safe operating procedures.
9. Replace any destroyed, missing or illegible decals and deflectors.
IMPORTANT: WHEN STORING DISC FOR WINTER, DO NOT LEAVE CYLINDERS UNDER HYDRAULIC PRESSURE, ESPECIALLY IF CYLINDERS ARE
ACTIVATED DURING COLD WEATHER. THE EXPANSION OF OIL WHICH TAKES PLACE WHEN WARM OR HOT WEATHER RETURN
MAY CAUSE SERIOUS DAMAGE TO CYLINDER, LINES OR HOSES.
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 AND CLOSE HYDRAULIC
LOCKUP VALVES BEFORE UNHITCHING

TROUBLE SHOOTING
PROBLEM POSSIBLE CAUSE REMEDY
OUTSIDE BLADES OF FRONT
GANGS ARE CUTTING TOO DEEP
CAUSING DISC TO RIDGE AT
OUTSIDE
- wheels raised off ground causing front of
disc to drop
- tire pressure is low on outer wheels
causing disc to cut deep at outside
- disc is lower at front than rear
- if above solutions do not solve problem,
outer blades may need to be raised
- lower wheels to ground so they gauge discing
depth, see Fig. 4 on page 7
- inflate tire, see tire pressures on page 5
- using levelling crank raise front of disc - see
Fig. 9 on page 11
- raise outer blades by placing a shim(s) between
front gang beam and inner mount bracket. See
detail “A” and “B” of Fig. 14. Shim(s) must be
ordered from parts
OUTSIDE BLADES OF BOTH
FRONT GANGS ARE NOT
CUTTING DEEP ENOUGH
- disc is higher at front than at rear - using levelling crank raise front of disc - see Fig. 9
on page 11.
OUTSIDE BLADE ON WING IS
CUTTING TOO DEEP - outside of wing frame is lower than main frame
- wing rockshaft cylinder is not synchronized
with main frame rochshaft cylinder
- raise outside of wing with wing rockshaft cylinder
anchor bolt see section 6 on page 12
- rephrase rockshaft cylinder, see section 17 on

with main frame rochshaft cylinder
- lower outside of wing with wing rockshaft cylinder
anchor bolt, see section 6 on page 12
- rephrase rockshaft cylinder, see section 17
on page 9
DISC IS LEAVING A RIDGE AT
CENTRE OF DISCING - rear gangs are cutting deeper than front gangs
- a high discing speed is causing disc to
throw dirt further resulting in a pile at centre
- gang angle too extreme
- rear gangs are too close together
- level disc using levelling crank - see Fig. 9 on
page 11
- reduce discing speed
- reduce gang angle if reduced gang will give desired
discing depth
- increase distance between rear gangs see section
1, paragraph C on page 11
