Attaching the Disc to the Tractor
The disc is equipped with a fixed tongue
attached to the disc hitch with two 1” grade 8
bolts. The tongue is designed to be
attached to a clevis type tractor drawbar.
Though not essential, for best results, the
tractor used to pull this unit should be
equipped with a swinging drawbar.
The following procedure is recommended to
attach the tractor to the disc. This procedure
is best carried out with the disc in the raised
position and the transport lock installed over
the hydraulic cylinder. se the hitch jack (A)
to raise or lower the tongue to the level
where it will fit into the tractor drawbar clevis.
Back the tractor to the drawbar tongue and
install the drawbar pin (B) and its retaining
hardware. This procedure may take more
than one attempt – safety takes time.
Install the safety chain (C).
CAUTION:
Do not allow others to stand between the tractor and disc when moving the tractor.
Do not allow others to position themselves to install the drawbar pin while operating the
tractor.
Prevent serious injury or death to you or others caused by unexpected movement of the machine.
Engage the parking brake and/or place transmission in PARK, shut off engine and remove key
before working around hitch.
Transporting the Disc
Clean the quick disconnects and tractor couplers before connecting. Shut off the tractor and move
the hydraulic levers back and forth to relieve pressure in open-center hydraulic systems. Connect
the hydraulic hoses to the tractor couplers. For ease of use, attach hoses in the corresponding
couplers which lower the disc when the hydraulic lever is moved forward and raises it when the
lever is moved backwards.
CAUTION:
Escaping fluid under pressure can penetrate skin causing serious injury. Avoid this
hazard by relieving pressure before disconnecting hydraulic lines. Tighten all
connections before applying pressure. Search for leaks with a piece of cardboard.
Protect your hands and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
Turn the jack handle to take weight off hitch jack. npin jack, remove pin, swing jack up into
transport (horizontal) position and re-pin.
If the tractor is equipped with a swinging drawbar, make sure the drawbar is locked in the center
position.
Connect warning lights to the tractor outlet and test they are operating properly. Make sure the
SMV sign is installed and visible from the rear of the disc.
Check tire pressure and wheel bolts – adjust and tighten if necessary.
10

Adjusting the Transport Levelling Control Arm
With the disc attached to the tractor, the hydraulics
connected and with the transport stay removed from
the hydraulic cylinder; the disc can be adjusted to
transport level as in illustration A. The adjustment is
carried out by turning the nuts indicated in the
illustration. When the disc is raised out of the ground
in the transport position, there is pressure against
these nuts. Therefore, to make adjustment easier,
lower the disc to the ground to take pressure off the
nut. The nut can then be turned easily by hand or
wrench. To lower the front of the disc as in illustration B, turn the nuts in the direction indicated as B.
To raise the front of the disc as in illustration , turn the nuts in the direction indicated as . It may be
necessary to raise and lower the disk a number of times to attain the desired result. Once the disc is
level, lock the nuts together on the eyebolt shaft. This adjustment remains unchanged as long as there
is no change in the tractor hitch height.
WARNING: To avoid serious injury to self or others, do not allow anybody on or near the disc
when it is being raised or lowered. In particular, if someone other than the tractor operator is
making adjustments to the disc, the tractor should be switched off while adjustments are
being made and only restarted when that person is well clear of the disc.
Transporting the Disc
Raise the disc to its maximum height by completely extending the
hydraulic cylinder. Install the transport stay over the hydraulic
cylinder rod with the plated end against the head gland of the
cylinder. Install the retaining pin. On tractors with open centered
hydraulics, switch the tractor off and relieve the hydraulic pressure
by moving the hydraulic spool lever back and forth. With closed
center systems, carefully use the hydraulics to take the pressure
off the hydraulics and allow the weight of the disc to be taken up by
the transport stay.
To prevent the wing sections from being accidentally
unfolded during transport, turn the shut-off handle fully
clockwise after folding the wings.
11

Transport Safety
□ Never allow riders on the tractor or disc. Serious injury or death can result from falling in the path
of the disk while in operation or transport.
□ Observe laws and regulations while transporting disc. Never transport disc at speeds greater
than 20 mph 32 km/h). Reduce speed and exercise caution on turns, bridges, rough roads,
steep grades and other adverse conditions.
□ Install all locking devices before transporting disc. Without these devices installed, the disc could
fall during transport and cause injury or death to the operator or bystanders and/or damage to the
disk, tractor and property.
□ Always used safety chains to secure the disc to the tractor during transport. Provide only enough
slack in chain to permit turning. A safety chain will help control drawn equipment should it
accidentally separate from the drawbar.
□ Ensure the load does not exceed the recommended specifications of the tractor. The tractor must
be heavy and powerful enough with adequate braking power for the towed load.
□ Keep the SMV emblem and side and rear reflectors clean and visible.
□ Use headlights, flashing warning lights and turn signals day and night. Follow local regulations for
equipment lighting and marking. Keep lighting and marking visible and in good working order.
Replace or repair lighting or marking that has been damaged or lost.
□ Use the proper size and grade of pin to attach the disc to the tractor.
□ If the tractor is equipped with a swinging drawbar, be sure to pin it in the center position before
transporting the disc.
□ Check wheel lug nuts for tightness and ensure tires are properly inflated and free of damaging
cuts and abrasions. The failure of either of these components can cause the disc to swing
uncontrollably and make it difficult to control the tractor.
□ Remove debris and loose soil from the disc before traveling on public roads. Falling debris and
soil can be a hazard to following and approaching traffic.
□ Do not tow another implement behind the disc unless proper modifications have been made and it
is permitted by local ordinances.
Operating Safety
□ Become familiar with the disc and its operation before using the unit. Read this manual carefully
and contact your dealer if you have any questions.
□ Never allow riders on the tractor or disc. Serious injury or death could result from falling in the
path of the disc while in operation or transport.
□ Be sure bystanders are clear of the disc before raising or lowering the disk. Accidental movement
of the controls or hydraulic failure could cause the disk to suddenly fall.
□ Be sure bystanders are clear of the disc before operating the disc. Before entering the tractor,
walk around the disc making sure no one is on, under or in front of the disc. Moving the disc
while someone is between or in front of the gang assemblies could result in serious injuries or
death.
□ Never work under a raised disc. Always lower the disc to the ground before inspecting or
servicing. Never rely on the hydraulic system to hold up the disc.
□ Use extreme caution when working around disc blades. The blades are sharp and could cut
hands, legs, etc. Wear gloves to handle disc blades or gang assemblies.
□ Do not operate close to ditches, deep bodies of water or on excessively steep slopes.
□ Before dismounting from the tractor to service or make adjustments, always
1. Lower the disc to the ground.
2. Shut the tractor off.
3. Engage the tractor’s parking brake or place transmission in park.
4. Relieve the hydraulics by moving the control back and forth.
5. Remove the key.
□ Unanticipated movement of the disc while working around the disk gangs could result in serious
personal injury or death.
12

Operating the Disc
GENERAL OPERATING GUIDELINES
□ Use the recommended size tractor.
□ Alwa s raise the disc out of the ground before turning. If pulling a harrow, roller or other toolbar
behind the disc, raise the disc just clear of the ground before turning.
□ In the field do not back-up with the disc in the full raised position. Raise the disc just clear of the
ground to prevent the disc from overbalancing to the rear which ma damage the control arms.
□ Speed, depth and soil t pe and condition all determine how level the ground left behind the disc.
To minimize ridging or gouging, limit the discing speed to 4-6 mph.
□ On tractors equipped with a swinging drawbar, allow the drawbar some movement when working
in level or gentl rolling fields. In severel rock conditions, heav cla or tree stumps allow more
swing in the drawbar. In all other conditions, lock the drawbar in the center position.
□ Pulling a drag or heav harrow behind the disc can reduce side draft and aid in levelling the soil.
ADJUST THE LEVELING CONTROL ARM
The leveling control arm is used to transfer pressure to the rear of the disc in order to increase
penetration of the rear disc blades. Pressure is increased b tightening the adjustment nut against
the spring. This adjustment is easiest to make when the disc is in the raised transport position and
there is no pressure on the nut. Once the desired setting is made, lock the first nut with the second
nut on the e ebolt. When the disc is lowered to the operating position, take care the spring is never
full compressed. Increasing pressure against the spring will put more down pressure on the rear
blades. Carr ing the disc slightl with the wheels while operating will allow the disc to pivot on the
wheels and result in more even blade penetration front to rear. If the disc is operated with the wheels
full raised, little or no pressure should be placed on the spring. If discing through a sharp
depression or ditch, raise the disc slightl to prevent excessive pressure on the spring and levelling
arm.
NOTE: Be sure to adjust both Levelling Control Arms identically to avoid stressing the
frames
13

Service and Maintenance Safety
□ Before servicing the disc, always:
1. Lower the disc to the ground.
2. Shut the tractor engine off.
3. Engage the tractors par ing bra e and/or place transmission in par .
4. Relieve the hydraulics by moving the control lever bac and forth.
5. Remove the ignition ey.
□ Never wor under a raised disc. The disc could fall suddenly causing serious personal injury.
Never rely on the hydraulic system to hold the disc up.
□ Periodically visually inspect the entire disc. Hydraulic fluid lea s and bro en, missing or faulty
parts can create a hazard. Ma e necessary repairs.
□ Use caution when inflating tires. Use a clip-on air chuc , extension hose with gauge, and stand to
one side away from the tire when inflating to avoid the possibility of personal injury due to blow-
offs, etc. Maintain proper air pressure in the tires. Never exceed the manufacturer’s maximum
pressure displayed on the sidewall of the tire.
□ Before disconnecting any hydraulic line relieve the pressure. Escaping hydraulic oil under
pressure can have sufficient force to penetrate the s in causing serious personal injury. If injured
by escaping hydraulic fluid, obtain medical treatment immediately.
□ Handle the gang assemblies with care. The disc blades are sharp and can cut or slice s in. Use
choc bloc s to prevent the gang assemblies from rolling during servicing. Wear gloves when
handling the disc blades or gang assemblies.
□ After wor ing on the hydraulic cylinder or any other components of the hydraulic system, carefully
cycle the hydraulic cylinder several times to purge air from the system and chec all components
for lea s. Always be sure the hydraulic lines are free of air and do not lea . ORB fittings may not
lea even though they are only finger tight – tighten with a wrench. Chec hydraulic hoses for
cuts or abrasions and replace if necessary.
□ Securely support any machine elements that must be raised for service wor . Use suitable lifting
devices and support stands where required. If using chains or straps ma e sure they are of
sufficient strength for the load and are in good repair.
□ To avoid injury wear gloves, steel-toe boots, safety glasses, hearing protection, safety helmet and
other safety equipment where warranted.
□ Understand the service procedure before doing the required wor . Keep the wor area clean and
dry.
14

Lubricate the Disc
□ The following illustrations highlight those areas of the disc subject to stress and wear. Unless
indicated otherwise, these fittings should be greased daily or after every 10 hours of operation.
□ Use a pressure lubrication gun and apply a sufficient amount of No. multi-purpose lithium
grease or equivalent to flush out the old grease. Wipe the grease fitting clean before greasing.
□ Grease all fittings before first use of the season and before storage at the end of the season.
□ Grease wheel bearings (F) sparingly – 6 ‘shots’ every 100 hrs.

Check the Oil-Bath Bearings
Visually check the oil-bath bearings daily. Oil-bath bearing assemblies can leak oil from three
locations and attention should be paid to these areas. A - Oil can seep from between the bearing
housing and the end cap or from around the bolts that hold the end cap to the housing. This condition
is caused by loose bolts or damaged gaskets. Gaskets are placed between the end cap and the
housing to preload the taper bearings in the housing. The solution is to tighten the bolts (30 ft lbs) or
replace the gaskets. B – Oil can seep past the check plugs. Plugs may use a pipe thread. Remove,
clean the threads, apply “pipe dope” or Teflon tape and reinstall. C – Oil may seep by the metallic
duo-cone seals. This may be caused by worn seals, loose gang axles or extreme temperature
fluctuations. Worn seals should be replaced immediately to prevent catastrophic bearing failure.
Such a failure will ruin all the other components of the bearing. Loose gang axles can allow the
bearing flanges to move outwards and thereby allow the seals to separate. Be sure to keep gang
axles tight. Because the seals are made of metal, they can expand and contract with extreme
temperature fluctuations. When they contract the sealing surfaces separate and small amounts of oil
can escape. This will normally occur when the disc is in storage. Putting the disc to use will normally
allow the seals to re-seat themselves. Check the oil and add 90W gear oil if necessary.
Adjusting the Scrapers
Adjust the scrapers as close to the disc
blades as possible without touching the
blades. To move a scraper, first loosen the
u-bolts (A) holding it to the scraper bar. Use
a hammer to alternatively tap the top side of
the u-bolts and the scraper itself in the
required direction. Once in position tighten
the u-bolts equally. Turn the blades
occasionally while tightening the u-bolts to
ensure the scraper is not contacting the disc
blade.
In some conditions (e.g. heavy trash or virgin
ground) plugging can occur at the bearings.
Removing the scrapers (B) at these locations
can alleviate the problem.
16

Repack and Pre-Load Wheel Hub Bearings
The wheel bearing pre-load should be set periodically or more often if transported frequently. Raise
the tire so it can rotate and:
1. Remove the dust cap from hub.
2. Remove cotter pin from nut and spindle.
3. hile turning the tire, tighten the castellated nut until there is a slight but noticeable drag on
the bearing. Do not back the nut off. Place the cotter pin in the nearest hole to secure the
nut. Replace the dust cap and gasket.
Repack the wheel hub bearings yearly by:
1. Remove the tire from the hub.
2. Remove the dust cap and gasket.
3. Remove the cotter pin and remove the castellated nut from the end of the spindle.
4. Slide the hub off the spindle taking care not to damage the seal..
5. Clean bearing cones, dust cap and nut with kerosene or other appropriate solvent.
6. Clean the inside of the hub and inspect the bearing cups and the seal. If they show
excessive wear or are damaged, replace both the cups and cones and seal. Though it is not
always necessary, it is advisable to replace the seal whenever repacking the hubs.
7. Pack the bearing cones and inside cavity of the hub with No. 2 multi-purpose lithium grease
or equivalent. Make sure no foreign material contaminates the lubricant.
8. Place the rear bearing cone into the back of the hub and press the seal into the hub. Place a
light film of grease on the seal surface and carefully slide the hub onto the spindle taking
care not to damage the seal.
9. Place the outside bearing cone over the spindle and into the hub.
10. Install the castellated nut and follow the procedure for setting the pre-load.
11. Reinstall the dust cap and tire.
Check the wheel lug nuts and wheel bearing pre-load after the next week of operation.

Keep Gang Assemblies Tight
□ To ensure proper function and maximum durability, the axle nuts should be checked and
tightened daily during the first (7) days of operation when the disc is new or after replacing any of
the gang components.
□ Loose axles may bend or break or cause damage to other components of the gang assembly.
aintaining tight gangs is necessary to ensure maximum bearing life.
□ A loose gang assembly is evident when some disk blades stop turning when discing or turn at a
different speed than other disks on the same assembly.
□ To tighten the axle without removing the gang assembly from the disc:
To minimize the possibility of thread damage, clean out the cavity between the inside of the nut
and the flat milled surface at the end of the axle. After using compressed air or a pressure
washer to remove as much material as possible, pour or spray a light oil or penetrating fluid into
the cavity.
Unbolt and remove the nut locks from the end washers on both ends of the axle.
Loosen but do not remove the bolts holding the bearings to the bearing standards.
Place one wrench on an axle nut to prevent the axle from turning.
Use the other wrench and an extension or a sledge hammer to tighten the axle nut on the opposite
end of the axle. Tighten the nut on 1-5/8” axle to 800-1000 ft/lbs and on a 2-1/8” axle to 1000-2000
ft/lbs.
Retighten the bearing bolts.
