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.
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.
Be Familiar with Safety Decals
Read and understand “Safety Decals” on page 6,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded, and
illegible decals.

2020-08-07 Table of Contents Index 401-705M
YP3025A Table of Contents Index Important Safety Information 2
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.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil, and
property.
Read and follow chemical manufacturer’s
instructions.
Wear protective clothing.
Handle all chemicals with care.
Avoid inhaling smoke from any type of chemical fire.
Store or dispose of unused chemicals as specified
by chemical manufacturer.
Use A Safety Chain
(Optional hydraulic hitch only. 3-Point has no chain.)
Use a safety chain to help control drawn machinery
should it separate from tractor draw-bar.
Use a chain with a strength rating equal to or greater
than the gross weight of towed machinery.
Attach chain to tractor draw-bar support or other
specified anchor location. Allow only enough slack in
chain to permit turning.
Replace chain if any links or end fittings are broken,
stretched, or damaged.
Do not use safety chain for towing.
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.

YP3025A Table of Contents Index Important Safety Information 3
2020-08-07 Table of Contents Index 401-705M
Minimize Radiation Exposure
The DICKEY-john RVS III Radar is an intentional radiator
of RF energy. Although its radiated energy level is far
below the limits set by EN 61010-1:1993
A2:1995-Chapter 12.4, it is advisable not to look directly
into the face of the unit.
The radar must radiate toward the ground and at least
8 inches (20 cm) away from a human during use to
comply with the RF human exposure limits as called out
in FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR
USE THE RADAR IN A MANNER INCONSISTENT
WITH ITS DEFINED USE.
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.
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.

2020-08-07 Table of Contents Index 401-705M
YP3025A Table of Contents Index Important Safety Information 4
Transport Machinery Safely
Maximum transport speed for implement is 20 mph
(32 km/h).
Maximum speed when turning is 13 mph (22 km/h).
Maximum speed when backing is 3 mph (5 km/h).
Some rough terrains require a slower speed.
Sudden braking can cause a towed load to swerve
and upset.
Do not transport cart in a train with material in the
tank.
Do not back the planter if PFC cart is attached.
Do not exceed 20 mph (32 km/h). Never travel at a
speed which does not allow adequate control of
steering and stopping. Reduce speed if towed load
is not equipped with brakes.
Comply with state and local laws.
Do not tow an implement that, when fully loaded,
weighs more than 1.5 times the weight of towing
vehicle.
Carry reflectors or flags to mark Planter in case of
breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting. Refer to transport
dimensions under “Tire Inflation Chart ” on
page 146.
Do not fold or unfold the Planter while the tractor is
moving
Shutdown and Storage
Lower Planter, put tractor in park, turn off engine,
and remove the key.
Secure Planter using blocks and supports provided.
Detach and store Planter in an area where children
normally do not play.

Practice Safe Maintenance
Understand procedure before doing work. Use
proper tools and equipment. Refer to this manual
for additional information.
Work in a clean, dry area.
Lower the Planter, put tractor in park, turn off
engine, and remove key before performing
maintenance.
Make sure all moving parts have stopped and all
system pressure is relieved.
Allow Planter to cool completely.
Disconnect battery ground cable (-) before
servicing or adjusting electrical systems or before
welding on Planter.
Inspect all parts. Make sure parts are in good
condition and installed properly.
Remove buildup of grease, oil or debris.
Remove all tools and unused parts from Planter
before operation.
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 Planter functions.
Operate machinery from the driver’s seat only.
Do not leave Planter unattended with tractor engine
running.
Do not stand between the tractor and Planter 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 Planter. Make sure all persons are clear of
working area.
