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.

2016-11-16 Table of Contents Index 401-406M
YP2425 and YP2425F 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.
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 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.

YP2425 and YP2425F Table of Contents Index Important Safety Information 3
2016-11-16 Table of Contents Index 401-406M
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.

Preparation and Setup
This section helps you prepare your tractor and YP24 for
use, and covers tasks that need to be done seasonally,
or when the tractor/planter configuration changes.
Before using the YP24 in the field, you must hitch the
planter to a suitable tractor, inspect systems, level the
planter. Before using the planter for the first time, and
periodically thereafter, certain adjustments and
calibrations are required.
Post-Delivery/Seasonal Setup
On initial delivery, use with a new tractor, and seasonally,
check and as necessary, complete these items before
continuing to the routine setup items:
•Install seed monitor console in tractor (page 142).
•Bleed hydraulic system (page 91).
•Wing leveling and alignment (page 93).
•Marker setup (page 54).
•Radar calibration (page 142).
•De-grease exposed cylinder rods if so protected at
last storage.
Pre-Planting Setup
Complete this checklist before routine setup:
Read and understand “Important Safety
Information” on page 1.
Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
Check that all grease fittings are in place and
lubricated. See “Lubrication and Scheduled
Maintenance” on page 102.
Check that all safety decals and reflectors are
correctly located and legible. Replace if damaged.
See “Safety Decals” on page 6.
Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 125.

2016-11-16 Table of Contents Index 401-406M
Hitching Tractor to Planter
Crushing Hazard:
Do not stand or place any part of your body between planter
and moving tractor. You may be severely injured or killed by
being crushed between the tractor and planter. Stop tractor
engine and set parking brake before attaching cables and
hoses.
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin
causing serious injury. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
If Weight Transfer is Installed
If the optional weight transfer system is not installed, or a
PTO pump is installed, continue at “Current Style Color
Coded Hose Handles” on page 18.
The weight transfer cylinders must be free to flex during
all planter movements where the system is not in active
use.
To allow cylinder flex:
•connect at least the fan case drain and fan return
lines to suitable receptacles, or
•install the shipping links (see page 143).
Machine Damage Risk:
Do not move the planter with a hydraulically locked weight
transfer system. Relieve the system or install shipping links.
If the cylinders are not free to flex, oil loss will result from even
minor movement flexing.

Hitching with 3-Point
Refer to Figure 4
1. Connect your tractor 3-point to the planter 3-point
hitch. If using quick hitch be sure planter locks into
hitch securely.
2. Raise tractor 3-point just enough to relieve pressure
from parking stands.
3. Swing up and pin up 3-point stands. See “Storing
3-Point Parking Stands” on page 21.
Load Sway Risk:
Adjust 3-point hitch arms and sway blocks to minimize any
side-to-side sway to assure proper tracking in the field and
safe road travel.
4. Connect hydraulic hoses to tractor remotes. See
“Hydraulic Hose Hookup” on page 17.
5. Connect electrical cables. See “Electrical Hookup”
on page 20.
6. Remove and store main tongue parking stand. See
“Store Main Parking Stand” on page 20.
Hitching with Hydraulic Tongue (Option)
Refer to Figure 5
1. Move the tractor to near hitching position.
2. Connect the hydraulic hoses for the tongue circuit.
This needs to be done before hitching in order to
raise and lower the tongue. See “Hydraulic Hose
Hookup” on page 17. Allow slack for hitch
movements. Close the tongue cylinder bypass valve.
3. Make electrical connections for at least the planter
control circuit (necessary to control planter hydraulic
systems). See page 20.
4. Check that hitch local bypass valve is closed.
Refer to Figure 6
5. Set the cab Clutch Folding Module Lift/Hitch
switch to Hitch.
6. Retract the Hitch/Lift circuit to set the tongue height
to clear the draw-bar. Back the tractor into alignment
and pin the draw-bar.
7. Connect safety chain to a suitable anchor point on
the tractor.
