8325 ROWCROP CULTIVATOR
The Orthman 8325 rowcrop cultivator is a versatile implement providing
producers with the benefit of performing numerous tasks with each field
pass. Introduced in 1999, the 8325 is designed around the time tested
8300 series cultivators. Integrating 8325 row units with a time tested
Orthman toolbar provides today’s producer with an industry leading cultivator.
Introduction
The 8325 row unit features a wraparound mount, parallel linkage, and
adjustable down pressure springs to provide uniform down pressure to
each row unit while allowing row units to work independent of the toolbar
to follow terrain contours. An adjusting hand crank and depth indicators,
for gauge wheel and center coulter depth adjustment, provide operators
with accurate and timely depth manipulation. Self storing, forward swept,
barring off discs allow for near crop tillage and optimum residue capacity
with simple adjustment and storage. These features equate to the benefit
of less time adjusting the implement and more time cultivating.
The 8325 provides a vast number of options in order to maximize each
field pass. Three sweep and ridging wing options provide precise control of
bed size and shape in conjunction with the cultivation. Optional fertilizer
tubes or a single fertilizer knife can be utilized to apply fertilizer with the
cultivation. An adjustable closed top fender is also available to protect a
young crop while maintaining desired ground speed.

The SAFETY ALERT SYMBOL warns of potential hazards to personal
safety and that extra precautions must be taken. When you see this
symbol, carefully read the message(s) that follow. Follow all recommended
precautions and safe operating practices in this manual.
(Hazard control and accident prevention are dependent upon safety awareness
and proper training of personnel involved in the operation of this equipment.)
BE AWARE OF SIGNAL WORDS
Signal words designate a degree or level of hazard seriousness.
These signal words include:
DANGER! WARNING! CAUTION!
DANGER indicates a hazardous situation that, if not avoided, will result in
death or serious injury. DANGER is limited to extreme situations, typically
for machine components which, for functional purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation that, if not avoided,
could result in death or serious injury. WARNING includes hazards that are
exposed when safety guards are removed. WARNING 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. CAUTION may also be used to alert
against unsafe practices.
SHUTDOWN AND STORAGE
AVOID CRUSHING. Lower implement to the ground, place tractor in park,
turn off engine, and remove key. Store implement on a clean, dry, and level
surface. An uneven surface could cause implement to shift or fall, resulting
in personal injury or death, as well as implement damage.

Orthman integrates as many safety features into the implement as
possible. You can avoid many hazards and possible accidents by
observing precautions in this safety section.
Insist that yourself, and others working with and around you, follow all
safety precautions. Be cautious working on and around implement to
avoid injury.

WARNING AND SAFETY LIGHTS
Slow moving vehicles and oversized implements create a hazard on public
roads. They are difficult to see, especially at night.
Make sure all warning, safety lights, and turning signals are working and
clean. Use safety lighting when using public roads day and night.
Replace missing or damaged lights immediately. Comply with state
and local laws governing implement safety lighting.
A safety lighting package, conforming to lighting standard
ANSI/ASAE S279.12, is available for addition to all 8325 cultivators.
Contact your Orthman dealer for safety lighting package information.
Refer to toolbar operator’s manual for safety lighting package instruction.
Important Safety Information
SAFE TRANSPORT
•Engage transport locking devices prior to transport.
•Plan your route to avoid traffic. Yield to traffic in all situations.
•Maximum transport speed is 20 mph (32 kph). Some conditions will
require reduced speeds. Travel at speeds that allow for adequate control
of stopping and steering.
•Operate implement from a position to provide maximum visibility. Know
transport height and gross weight of implement. Be aware of overhead
obstructions. Do not use bridges rated lower than your gross weight.
•Make sure a slow moving vehicle (SMV) placard is mounted to the
implement and visible to other motorists. All Orthman implements
are equipped with a SMV placard.
•Make allowances for increased implement size when transporting. Sudden
braking can cause a towed load to swerve and/or rollover. Never use
independent braking with implement in tow as loss of control and/or rollover
can result. Reduce speed if towed implement is not equipped with brakes.
•Do not coast. Always keep tractor or towing vehicle in gear to provide
engine braking when traveling downhill.
•Comply with state and local laws governing implement transport.

• READ AND UNDERSTAND THIS MANUAL BEFORE OPERATING OR
SERVICING IMPLEMENT.
Implement is to be operated by qualified
personnel only. Never let children operate implement. A complete
understanding of safety precautions, operation, and maintenance is
mandatory before implement use.
•
AVOID CRUSHING.
Make sure all persons are clear of implement at all
times implement is in use. Be aware of obstructions above below, and
around implement while in operation or transport. Serious injury or death
can result from being struck by implement.
•
AVOID ROLLOVER.
Do not fold or unfold implement and avoid sharp turns
when on a hillside, as shift of weight could cause rollover. Operate
implement at a safe distance from terrain irregularities and other
obstructions that could cause rollover.
•AVOID ELECTROCUTION.
Be aware of overhead power lines. Contact
or close proximity to power lines can result in serious injury or death.
Use extreme care when operating implement near power lines.

not in front or rear of the wheel assembly. Only mount or dismount tires if
you possess proper equipment, otherwise contact a trained professional.
Always maintain correct tire pressure. Inspect tires and wheels daily. Do not
operate tires with low pressure, cuts, visible damage, or missing hardware.
• Make sure there is adequate ventilation. Never operate a combustion
engine in an enclosed area. Exhaust fumes can cause asphyxiation.

Preparation and Setup
PREPARING THE CULTIVATOR
The majority of the 8325 cultivator is assembled at Orthman Mfg., Inc.
To ensure safe and efficient transport from the manufacturer,
various tooling options may need to be installed upon delivery.
•All tooling options available to complement 8325 row units are illustrated
and explained in the tooling options and installation section of this
manual. All tooling field adjustments are illustrated and explained in the
field settings section of this manual.
•If an Orthman toolbar is used in conjunction with 8325 row units, be sure
to consult the toolbar operator’s manual before attempting to operate the
implement. Read and understand manuals for all machinery used in
conjunction with the 8325 cultivator.
•Before each use, check hardware for wear and proper torque. Replace
damaged or missing hardware with hardware of an identical grade to
restore implement to original specifications.
IMPLEMENT TO TRACTOR CONNECTION
3 - 1
•AVOID CRUSHING. Do not stand between tractor and implement when
connecting or disconnecting implement. Serious injury or death can
result from being trapped between the tractor and implement.
•Once implement is securely connected to the tractor, tooling may need
to be installed prior to proceeding with field setting adjustments. Lower
implement to the ground, place tractor in park, turn off engine, and
remove key. Park implement on a clean, dry, and level surface. An
uneven working surface could cause implement to shift or fall, resulting
in personal injury or death, as well as implement damage.
•USE BAR STANDS TO SUPPORT THE IMPLEMENT. Securely support all
implement components that must be raised.

desired tillage depth and desired amount of residue flow. Generally, deeper
discs generate more residue flow. Width adjustments allow for variations

could cause implement to shift or fall, resulting in personal injury or death, as well as
implement damage.

components that must be raised. Remove any buildup of grease, oil, or debris prior to
installing barring off discs.
