Attaching the Disc to the Tractor
The disc is equipped with a heavy tongue that both
flexes and swivels to accommodate the most rugged
terrain including large rocks and tree stumps. This is
an essential design feature; however it requires extra
care when attaching the disc to a tractor.
For best results, the tractor used to pull this unit should
be equipped with a swinging drawbar with a clevis end.
The following procedure is recommended.
This procedure is best carried out with the disc
in the raised position and the transport lock
installed over the hydraulic cylinder. Use the
hitch ack to raise or lower the tongue to the
level where the tongue will lay on the drawbar.
Unpin the swinging drawbar and slide it to one
side. Back the tractor to the approximate
point where swinging the drawbar back to the
center will trap the tongue in the clevis. With
the tractor parked and the brake engaged, lift
the tongue (2) and swing the drawbar into the
center position (1).
Install the drawbar pin and its retaining
hardware. This may require moving the tractor
forward or backward slightly. An articulated
tractor or belted tractor can swing the drawbar
side to side by turning the steering wheel
slightly. This procedure may take more than
one attempt – safety takes time.
Attach the safety chain.
If the tractor is not equipped with a swinging
drawbar, it is recommended to fabricate a prop
from a length of wood to hold up the tongue
while the tractor is backed into place.
CAUTION:
Do not allow others to stand between the tractor and disc when moving the
tractor.
Do not allow someone to hold up the tongue while backing the tractor into
place.
Prevent serious in ury 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 both quick disconnects and tractor couplers before connecting. Shut
off the tractor engine and move the hydraulic levers back and forth to
relieve pressure in the hydraulic system. Connect the hydraulics hoses to
the tractor hydraulic couplers. For ease of use it is recommended the
hoses be attached in the order which lowers the disc when the hydraulic
lever is pushed forward and raises it when the lever is pulled back.
□
C UTION: Escaping fluid under pressure can penetrate the skin causing serious injury. void this
hazard by relieving the pressure before disconnecting hydraulic or other lines. Tighten all the
connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and
body from high pressure fluids.
If an accident occurs, see a doctor immediately. ny fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
□ Turn jack handle to take weight off hitch jack. Unpin jack, remove pin, swing jack up into transport (i.e.
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 make sure they are functioning properly. Make sure
the SMV sign is installed and visible from the rear of the machine.
□ Check tire pressure and adjust if necessary.
Transport Leveling Adjustment
.

13
The implement can be adjusted so the frame is level front to rear for transport and when it is raised out of
the ground to turn. This is accomplished by adjusting nuts (C) on eyebolt (A). n the lowered Work
Position, the eyebolt (A) slides out of tube (B). This allows the hitch/bridle assembly to “float” while
discing. When the implement is raised to Transport Position, the eyebolt (A) slides into tube (B) until the
tube contacts the nuts (C). At this point the hitch/bridle assembly no longer “floats” and becomes fixed
relative to the frame.
f the frame is lower at the front in the Transport Position: Lower the disc to the work position to take
pressure off the nuts (C). Turned the nuts clockwise (viewed from front of disc). Raise the disc back to
transport position and check for level. Repeat if necessary and lock the nuts together.
f the frame is higher at the front in the Transport Position: Lower the disc to the work position to take
pressure off the nuts (C). Turn the nuts counterclockwise (viewed from front of disc). Raise the disc back
to transport position and check for level. Repeat if necessary and lock the nuts together.
CAUTION: n the Work Position, the tube (B) must not be in contact with the nuts (C). The leveling
linkage may be damaged if the hitch/bridle assembly cannot “float” in the Work Position.
Install the Transport Stay
Raise the disc to its maximum height by completely
extending the hydraulic cylinder. nstall the transport stay
over the hydraulic cylinder rod with the plated end against
the head gland of the cylinder. nstall the pins provided.
Switch the tractor off and move the hydraulic lever back
and forth, releasing the pressure in the system and
allowing the weight of the disc to be taken up by the
transport stay.
MPORTANT: Never transport the disc without the
transport stay installed on the hydraulic cylinder.
Transport Safety
□ Never allow riders on the tractor or disc. Serious injury or death can result from falling in the path of
the disc 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.
□ nstall 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 disc,
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.

14
□ 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.
□ eep 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. eep 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 the Disc
General Operating Guidelines
□ Use the recommended size tractor. Weight is as important as horsepower. Too light a tractor will be
overpowered by the plowing action of the disc and its front end will be swung to the left, requiring
constant steering corrections.
□ Always 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 fully raised position. This will prevent the disc from
overbalancing to the rear which may damage the control arms.
□ Speed, depth and soil type 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 gently rolling fields. In severely rocky conditions, heavy clay or tree stumps allow more swing
in the drawbar. In all other conditions, lock the drawbar in the center position.
□ Pulling a drag or heavy harrow behind the disc can reduce side draft and aid in levelling the soil.
Disc Adjustments
All single offset discs have a single characteristic in common. Because the front gang of disc blades are
set at an angle to their direction of movement and because these blades are working in “new” ground
compared to the rear discs which are working in ground already partially tilled by the front blades, a single
offset disc tries to rotate clockwise as it is pulled forward through the field. To perform optimally and to
reduce stress and premature wear on components, it is desirable that the machine draft in a straight line
behind the tractor. As well, the concavity of the disc blades is such that in the center angle setting the
blades will accomplish the most tillage with the least horsepower and minimum wear to the blades. When
the disc drafts to one side (i.e. “dog tracking” or “crabbing”) the gang angles are changed and the quality
of the tillage suffers.

15
Hitch Assembly Adjustments
The draft of the disc can be changed by moving the hitch assembly to one of four positions. Position B is
considered the center position and suitable for most conditions. Sliding the hitch to Position A will cause
the rear of the disc to move to the left when viewed from the rear looking forward. lipping the hitch over
and attaching in either Position C or D will cause the rear of the disc to move progressively to the right
when viewed from the rear looking forward.
NOTE: Towing another tool behind the disc will affect its draft.
The Model 800 is designed with a parallel lift undercarriage. The undercarriage is positioned such that
the weight of the unit is balanced between the front and rear of the disc. Lifting and lowering the disc
does not significantly change this distribution. or this reason the disc does not require a leveling control
assembly for field operations.

16
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 in ury 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 disc. Accidental movement of
the controls or hydraulic failure could cause the disc to suddenly fall.
□ Be sure bystanders are clear of the disk 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 in uries 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 ad ustments, 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 disc gangs could result in serious
personal in ury or death.

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
p.s.i. 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.

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 dail or after ever 10 hours of operation.
□ Use a pressure lubrication gun and appl a sufficient amount of No. 2 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.

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 disc blades stop turning when discing or turn at a
different speed than other discs 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
(i.e. 4 to 5 foot length of 2” pipe) or a
sledge hammer to tighten the axle nut on
the opposite end of the axle. Tighten the
nut to approximately 2000-2200 ft/lbs.
Retighten the bearing bolts. If the gang is
excessively loose it may be necessary to completely disassemble the entire assembly and clean the
mating surfaces between the spools, bearings, end washers and disc blades.
□ If it is necessary to remove and disassemble the gang assembly, use suitable lifting devices and
supports to prevent injury.
With the disc lowered to the ground, first remove the scrapers and then unbolt the bearings from
the bearing standards. There are four 1-1/4” x 5” bolts holding each gang assembly to the gang
bar. Once the bolts are removed, raise the disc high enough to either roll or pull the assembly
from under the disc. Block the gang to prevent it from rolling. Remove the nut locks from both
ends of the assembly. Use one wrench to keep the gang from turning while using the other
wrench to tighten the nut at the opposite end of the assembly.
It may not be possible to properly tighten the gang if dirt, grit or debris has built-up between the
components. In this case remove a nut from one end of the axle, slide off the end washers,
bearings, spools and disc blades. Thoroughly clean the mating surfaces between the
components and reassemble on the disc gang (see assembly section). Clean the threads on the
axle and in the axle nut. Apply an anti-seize compound to the axle threads and reinstall the nut.
Tighten the nut and reinstall the nut locks. Place the assembly under the disc and bolt to the
gang bar bearing standards. Occasionally turn the gang while tightening the bolts to check the
gang turns freely. Retighten the bearing bolts after the first 10-12 hours of operation.
