Operation & Maintenance
Your Ashland disc harrow is a durable piece of equipment and with proper care will yield
many years of trouble-free operation. However, the life of your machine can be severely
shortened by poor maintenance. You must follow consistent maintenance practices and use
superior quality grease and hydraulic oil (compatible with the power unit’s hydraulic system)
to insure the longest, most productive use from your disc harrow.
Your disc harrow should be greased at all points where grease fittings are provided.
REMOVE TRANSPORT LOCKS prior to operation. Next, extend and retract all cylinders
several times to force out any air from the hydraulic cylinders and lines. Check the oil levels
in the tractor hydraulic system and add to maintain the proper level. Care should be used
when adding oil or when disconnecting any oil line to keep all dirt out of the oil as dirt is a
major factor in the failure of hydraulic components.
When your disc harrow is placed into operation, the operator will have to “feel out” the
amount of depth of cut to obtain maximum cutting efficiency. This is usually accomplished
by taking a lesser and more uniform cut; however, some soil conditions such as loose sand
may require a “pumping action” obtained by taking successive deep cuts and lifting out of
cut as the tractor begins to lose power or traction.
After 8 hours of operation, all bolts should be checked and tightened if necessary and all
grease fittings lubricated. Check tire pressures daily. Also, check pins and cutting edges for
signs of wear.
After 50 hours work, all bolts should be rechecked and tightened if necessary. Check wheel
bearings and adjust if necessary.
Check wheel lug nut torque.
•After first 2 hours of operation.
•Recheck daily for the next 2 weeks.
•Tighten wheel lug nuts in a star pattern.
•Torque wheel lug nut (see Torque Specifications).
After 300 hours work, clean and repack wheel bearings and replace, if necessary, cutting
edges, worn pins, etc.
Failure to replace worn cutting edges may result in unnecessary wear to
the machines sides and floor.
Before starting a job, make sure Diggers Hot Line has been contacted and all underground
utilities have been properly located (electric, phone, and pipelines). Have a clear
understanding of all local, OSHA, and MSHA rules that apply to the job. Beware of your
environment and keep others a safe distance from the machine while familiarizing yourself
with the machine’s controls. The machine requires a power source with TWO 4-way (double
acting) hydraulic control valves.

Safety Guidelines
Safety Signal Words:
Please note the use of signal words such as DANGER, WARNING, and CAUTION paired with
the safety messages on your disc harrow. The appropriate signal word for each safety
message has been selected using the following guidelines:
Operator safety is a main concern in designing and developing equipment. Designers and
manufacturers include as many safety features as possible. However, every year many
accidents occur on job sites which could have been avoided by extra thought and a more
careful approach to handling equipment. The operator can avoid many accidents by
observing the precautions in this section. To avoid personal injury, study the following
precautions and insist those working with, or for you, follow them.
Replace any CAUTION, WARNING, DANGER, or instruction safety decal that is not readable
or missing.
Do not attempt to operate this equipment under the influence of drugs or alcohol.
Review the safety instructions in the operator’s manual with all users annually.
Operators should be responsible adults who are familiar with machinery
and trained in the equipment’s operations. Do not allow persons to
operate or assemble this unit until they have read this manual and the
owner’s manual and have developed a thorough understanding of the
safety precautions and machine operation.
•DANGER: Indicates an imminently hazardous situation that, if not avoided, will
result in death or significant injury. This signal word is limited to the most
extreme situations –typically for machine components which, for functional
purposed, cannot be guarded.
•WARNING: Indicates a potentially hazardous situation that, if not avoided,
could result in death or significant injury. For example, hazards that are
exposed when guards are removed. This signal word may also be used to alert
against unsafe practices.
•CAUTION: Indicates a potentially hazardous situation that, if not avoided, may
result in minor or moderate injury. This signal word may also be used to alert
against unsafe practices.

Tire Service
The task of servicing tires and wheels can be extremely dangerous and should be
performed by trained personnel only, using the correct tools and following best-
practice. Do not attempt to mount, demount, or inflate a tire if you do not have the
proper equipment and experience to perform the job. Call a qualified repair service
to inspect the assembly and make necessary repairs. Failure to heed warnings
could lead to serious injury or death.
Visually inspect tires and wheels daily. Carefully inspect any rim and tire assembly that has
been run underinflated or flat before reinflating the tire to make sure there is no damage to
either the rim or tire.
•ALWAYS wear personal protection equipment such as gloves, footwear, eye protection,
hearing protection, and head gear when servicing tire and wheel components.
•DO NOT operate with damaged rims, tire cuts or bubbles, missing lug bolts, or nuts or
damaged rims.
•ALWAYS maintain the correct tire pressure. NEVER exceed recommended tire inflation
pressure.
•INSPECT any rim and tire assembly that has been run flat or severely underinflated before
reinflating the tire. Damage to the rim and tire may have developed.
•NEVER reinflate a tire that has lost air pressure or has been run flat without determining
and correcting the problem.
•NEVER try to repair wheel, rim, or tire components parts. Parts that are cracked, worn,
pitted with corrosion, or damaged must be discarded and replaced with good parts.
•ALWAYS use approved tire and rim combinations for the model that you have and verify
that part numbers of components are correctly matched for the assembly.
•ALWAYS exhaust all air from the tire prior to demounting.
•ALWAYS place wheel and tire assemblies in restraining devices (safety cage) when inflating
tires. Use a clip-on chuck and long extension hose to allow you to stand to the side of the
tire and not in front of it.
•NEVER weld or cut on an inflated tire assembly. Welding heat can cause increased
pressure which could result in tire explosion.
•ALWAYS use proper lifting techniques and mechanized lifting aids to move heavy
components and assemblies.
•NEVER leave a tire, wheel, or assembly unsecured in a vertical position.
•ALWAYS take care when moving tires and wheels, making sure that other people in the
area are not endangered.

Hub Service
Maintenance Schedule
•Daily visual inspection
•Thorough inspection for leaks or damage every
300 hours of operation
•5 pumps of grease every 300 hours of operation
•Thorough cleaning, inspection, and repacking
every 1,500 hours of operation
The bearings within the hubs of the disc harrow are fully greased with a Mobilith SHC™ 460
grease at the factory. Ashland uses a special bearing grease packer to ensure the bearing is
effectively and evenly lubricated. Generous amounts of additional grease are added on both
sides of the bearing prior to install within the hub.
Mobilith SHC™ 460
Mobilith SHC™ Series high-performance, lithium complex synthetic greases are developed to protect
equipment in severe applications operating at extreme temperatures. Their excellent adhesion,
structural stability, and resistance to water conditions found in wet environments make them
suitable for use in a wide variety of machinery and components. This grease exhibits excellent wear,
rust, and corrosion protection, to help with mechanical efficiency, enhance bearing and equipment
life, and extended grease life. Resulting in reduced maintenance costs, energy consumption,
starting torque, and provided protection at high and low temperatures.
Reinstalling Hubs
Before installing or re-installing the hub, follow this procedure to ensure spindle machined surfaces
are clean and undamaged.
•Remove old lubricant and thoroughly clean spindle.
•Inspect machined spindle seal surface for nicks, scratches, burrs or marks. If needed, use crocus
cloth or emery cloth to repair damaged areas.
•Clean spindle threads thoroughly with a wire brush to avoid false bearing adjustments and to
avoid introduction of contaminates into the hub.
•Thoroughly clean spindle machined surfaces of rust, dirt, grease, or other contaminants that
could damage the hub seal and cause it to leak.
Caution
Too much grease volume (over-greasing) in a bearing cavity will cause the rotating bearing elements
to begin churning the grease, pushing it out of the way, resulting an increase of bearing component
temperatures. This leads to rapid oxidation (chemical degradation) of the grease as well as an
accelerated rate of oil bleed, which is a separation of the oil from the thickener. The heat that has
been generated over time along with the oil bleed eventually will cook the grease thickener into a
hard, crusty build-up that can impair proper lubrication and even block new grease from reaching
the core of the bearing. This can result in accelerated wear of the rolling elements and then
component failure.

Warranty Statement
The Purpose of Warranty
Ashland Industries, Inc. warrants each new product to be free from defects in material and
workmanship. This warranty is applicable only for the normal service life expectancy of the product
or components, not to exceed one year from the date of delivery of the new Ashland Industries
product to the original purchaser, or the date the product is first put into service via a rental
agreement or other means, whichever occurs first.
Dealers Responsibilities
The following responsibilities are to be performed when the dealer delivers a product to the
purchaser or otherwise places it into warranty service:
•Complete the Warranty Registration Form and forward it to Ashland Industries within 30 days of
the sale, rental or other use of the product. Warranty reimbursement is contingent upon product
registration.
•Review the warranty statement and operator’s manual with purchaser to assure understanding of
purchaser’s responsibilities as related to warranty, service, and the proper and safe operation of
the product. Purchasers/Renters should be advised to have failed parts repaired or replaced
immediately upon failure, as continued use will result in additional damage, excessive wear, and
may result in personal injury.
•Contact Ashland Industries prior to beginning repair or replacement of failed parts to make
certain that the cost of repairs are consistent with the value of the product being sold.
•Warranty requests for units in dealer’s inventory may be submitted to Ashland Industries when
defects are noted in products prior to the retail sale or rental of that unit.
•Provide warranty and service repairs as directed by Ashland Industries’ “Service Repairs Bulletins”
or other instructions.
•All warranty work must be completed within 30 days of failure. Notify Ashland Industries’
warranty department if repairs will require more than 30 days after failure for an extension. No
claim will be accepted for warranties that exceed this 30 day period.
•No warranty will be allowed on units delivered to the retail customer prior to the full payment of
that unit to the manufacturer by the dealer.
•If diagnostic time is required, contact Ashland Industries prior to beginning the warranty repair
for approval. Ashland Industries must approve travel time reimbursement prior to beginning the
warranty repair.
Ashland Industries Responsibilities
•Reimbursement for parts used in warranty repair will be credited only when the parts are
purchased from Ashland Industries Inc. Parts will be credited at dealer’s net cost. No warranty
will be allowed on parts that are past due.
•Dealer should use parts from their parts inventory first. In the event that parts must be shipped
from Ashland Industries Inc., freight will be paid by Ashland Industries and will be shipped by the
most economical means to arrive in the shortest possible time. Air, Next Day Air, Priority and
other special shipment methods requested by the dealer will be at the customer’s expense.
