INTRODUCTION
Read and study manual completely before at-
tempting to operate this implement. Take this
manual to the eld for handy reference when op-
erating, adjusting or servicing the implement.
“Right-Hand” and “Left-Hand” sides of the
machine are determined by standing behind
the implement and facing in the direction of
forward travel.
This symbol identies important safety
messages. When you see it, read the
message that follows and be alert to the pos-
sibility of personal injury.
Remember, safety instructions stated in this
manual are for your protection. Read them
carefully before using this machine.
This manual covers operation, service, parts,
and assembly of your implement.
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!
OM-00229-A
No accident-prevention program can be successful without the wholehearted cooperation of
the person who is directly responsible for the operation of the equipment.
Accidents can be prevented only by the operator anticipating the result before the accident
is caused and doing something about it. No power-driven equipment, whether it be transportation
or processing, whether it be on the highway, in the harvest eld, or in the industrial plant, can be
safer than the person who is at the controls. If accidents are to be prevented -- and they can be
prevented -- it will be done by the operators who accept the full measure of their responsibility.
It is true that the designer, the manufacturer, the safety engineer can help; and they will help,
but their combined efforts can be wiped out by a single careless act of the operator.
It is said that, “the best kind of a safety device is a careful operator.” We, at Unverferth Mfg.
Co., Inc. ask that you be that kind of operator.

No accident-prevention program can be successful without the wholehearted cooperation of the person
who is directly responsible for the operation of the equipment.
A large number of accidents can be prevented only by the operator anticipating the result before the
accident is caused and doing something about it. No power-driven equipment, whether it be trans-
portation or processing, whether it be on the highway, in the harvest eld, or in the industrial plant,
can be safer than the person who is at the controls. If accidents are to be prevented--and they
can be prevented--it will be done by the operators who accept the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help; and they will help,
but their combined efforts can be wiped out by a single careless act of the operator.

SAFETY
• Read and understand this operator’s manual, and the towing vehicle’s operator’s
manual, before operating.
• All machinery should be operated only by trained and authorized personnel.
• To prevent machine damage, use only attachments and service parts approved by
the manufacturer.
• Always shut power unit and towing vehicle engine off and remove key before
servicing the Seed Runner.
• Avoid personal attire such as loose tting clothing, shoestrings, drawstrings, pants
cuffs, long hair, etc., that may become entangled in moving parts.
• Do not allow anyone to ride on the implement. Make sure everyone is clear before
operating.
FOLLOwING SAFETY INSTRUCTIONS
• Avoid working under the unit; however, if it becomes absolutely unavoidable, make
sure the implement is safely blocked.
• Always make certain everyone and everything is clear of the machine before
beginning operation.
• Turn engine off and remove key from ignition before servicing or adjusting
equipment.
• Verify that all safety shields are in place and secured.
• Ensure that all applicable safety decals are installed and legible.
• Explosive gas from the battery can cause res and severe acid burns. Charge the
battery only in a well ventilated area. Keep sources of ignition away.
• Explosive separation of a tire and rim can cause serious injury or death. Only properly trained
personnel should attempt to service a tire and wheel assembly.
BEFORE OPERATING OR SERVICING
(March 2013)

• Secure transport chains to Seed Runner and to towing vehicle before transporting.
DO NOT transport without chains.
• Install transport locks before transporting.
• Check that the brake controller is energized.
• Comply with state and local laws governing highway safety when moving
machinery.
• Use approved accessory lights, reectors and devices when transporting at night
and during periods of poor visibility.
SAFETY
• Regulate speed to eld conditions. Maintain complete control at all times.
• Never lubricate equipment when in operation.
• Carbon monoxide can cause severe nausea, fainting or death. Do not operate engine in
closed or conned area.
• Explosive fuel can cause res and severe burns. Stop engine before lling fuel tank.
• Hot parts can cause severe burns. Do not touch engine while operating or just after stopping.
• Seed being transported may contain seed treatment. Read and follow all requirements for
personal protective equipment and rst aid as outlined on seed tags.
• Keep away from overhead power lines. Electrical shock can cause serious injury
or death.
• Do not attempt to move any objects away from moving parts.
• Use extreme care when operating close to ditches, fences, or on hillsides.
• Do not leave towing vehicle or Seed Runner unattended with engine running.

• Relieve pressure before disconnecting hydraulic lines or servicing hydraulic system. See the
Maintenance section of this manual for the procedure to relieve pressure.
• Use a piece of cardboard or wood to detect leaks of hydraulic uid under pressure. Correct
hydraulic leaks immediately.
• High-pressure uids can penetrate the skin and cause serious injury or death.
Seek medical treatment immediately if injured by high-pressure uids.
• Never loosen or remove any hydraulic tting without rst verifying that all uid pressure has
been relieved. Failure to do so may result in unintended movement of all or a portion of the
equipment, possibly causing severe injury or death due to crushing or cutting. Injury may also
occur from contact with oil under pressure that may escape during tting removal.
• Hydraulic system must be purged of air before operating to prevent serious injury or death.
• Do not bend or strike high-pressure lines. Do not install bent or damaged tubes or hoses.
• Repair all oil leaks. Leaks can cause res, personal injury, and environmental damage.
• Route hoses and lines carefully to prevent premature failure due to kinking and rubbing against
other parts. Make sure that all clamps, guards and shields are installed correctly.
• Do not relieve hydraulic system pressure by loosening a tting.
• Tighten all connections before applying pressure. Keep hands and body away from hydraulic
leaks which eject uid under high pressure.
• Check hydraulic hoses and tubes carefully. Replace components as necessary if any of the
following conditions are found:
- End fittings damaged, displaced, or leaking.
- Outer covering chafed or cut and wire reinforcing exposed.
- Outer covering ballooning locally.
- Evidence of kinking or crushing of the flexible part of a hose.
- Armoring embedded in the outer cover.
• Use good judgment when transporting equipment on highways. Regulate speed
to road conditions and maintain complete control.
• Maximum speed of implement should never exceed 20 mph. Do not exceed 10
mph during off-highway travel.
• Slow down before making sharp turns to avoid tipping. Drive slowly over rough
ground and side slopes.
• Do not transport unit with rear compartment full and front compartment empty. The
unit may not be properly balanced, offsetting the trail ability of the Seed Runner.
