Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Use Adequate Lifting Means
The frame sections and gangs of this machine are
extremely heavy. If using multiple lifters, make sure each
is rated for at least its share of the load.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.

9322-9756PP Table of Contents Index Important Safety Information
Be Familiar with Safety Decals
Read and understand the “Safety Decals” section of the
Operators Manual.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.
Wear Protective Equipment
Wear protective clothing and equipment.
Wear clothing and equipment appropriate for the job.
Avoid loose-fitting clothing.
Because prolonged exposure to loud noise can cause
hearing impairment or hearing loss, wear suitable
hearing protection such as earmuffs or earplugs.
Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
operating machinery.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
If an accident occurs, seek immediate medical assistance
from a physician familiar with this type of injury.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can create
a hazard when driven on public roads. They are difficult
to see, especially at night.
Use flashing warning lights and turn signals whenever
driving on public roads.
Use lights and devices provided with implement
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
Never allow children to operate equipment.
Keep all bystanders away from machine during operation.
Shutdown and Storage
Lower implement, put tractor in park, turn off engine, and
remove the key.
Secure Plains Plow using blocks and supports provided.
Detach and store Plains Plow in an area where children
normally do not play.

Tire Safety
Tire changing can be dangerous and should be
performed by trained personnel using correct tools and
equipment.
When inflating tires, use a clip-on chuck and extension
hose long enough for you to stand to one side–not in front
of or over tire assembly. Use a safety cage if available.
When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
Be familiar with all machine functions.
Operate machinery from the driver’s seat only.
Do not leave machine unattended with tractor engine
running.
Do not stand between the tractor and machine during
hitching.
Keep hands, feet and clothing away from power-driven
parts.
Wear snug-fitting clothing to avoid entanglement with
moving parts.
Watch out for wires, trees, etc., when folding and raising
machine. Make sure all persons are clear of working area.

you hookup hoses to your tractor outlets. Hoses that
go to the same remote valve are marked with the
same color.
Refer to Figure 10

38. To distinguish hoses on the same hydraulic circuit,
refer to hose handles. The hose under an extended-
cylinder symbol feeds a cylinder base end. The hose
under a retracted-cylinder symbol feeds a cylinder

High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when

58x3 132 x4 12u-bolt (4), secure with 58lock
washers and 58nuts.
51. Tighten all bolts to specs, See “Torque Values
Chart” on page 16.
A-Frame Hitch
Refer to Figure 13
52. Attach a-frame hitch (1) to rear of center frame with
58x 3132 x 512u-bolts (2), 58lock washers and
58nuts.
53. Hitch will have either the flex slide assembly (3) or
the rigid slide assembly (4). There will be a
34x1 12hex bolt (5) and 34jam nut in front hole of
assembly to keep the slide assembly from sliding
clear out.
54. Tighten all bolts to specs, See “Torque Values
Chart” on page 16.

machine as possible with 58x 4 x 512u-bolts (2),
58lock washers and 58nuts.
56. Slide the rear stand (3) through the rear stand
bracket (1), secure with the 34x 412pin rear stand
bracket (4) and retainer.
57. Once the options are installed, fold the Plains Plow
to check for clearance and interferences, also watch
that hoses do not get pinched.
Double check that all bolts are tightened to specs,
See “Torque Values Chart” on page 16.Consult the
“Operator’s Manual”, for the first time field
adjustments before going to the field.
