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 5,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
2014-07-21 Table of Contents Index 591-049M
2 LC40 Table of Contents Index Great Plains Manufacturing, Inc.
Wear Protective Equipment
▲ Wear clothing and equipment appropriate for the job.
▲ Prolonged exposure to loud noise can cause hearing
impairment or loss. Wear suitable hearing protection such
as earmuffs or earplugs.
▲ Avoid wearing entertainment headphones while operating
machinery. Operating equipment safely requires the full
attention of the operator.
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.
591-049M Table of Contents Index 2014-07-21
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Transport Machinery Safely
Maximum transport speed for implement is 20 mph
(32 km/h). Some rough terrains require a slower speed.
Sudden braking can cause a towed load to swerve and
upset.
▲ 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 unless the towing vehicle is rated
for, and ballasted for, the weight of the implement.
▲ Carry reflectors or flags to mark implement in case of
breakdown on the road.
▲ Do not fold or unfold the implement while the tractor is
moving.
Check for Overhead Lines
The implement requires at least 14 feet (4.3 m) vertical
clearance in transport. Contacting overhead electrical
lines can introduce lethal voltage levels on implement
and tractor frames. A person touching almost any metal
part can complete the circuit to ground, resulting in
serious injury or death. At higher voltages, electrocution
can occur without direct line or body contact.
▲ Avoid overhead lines during folding, unfolding, transport
and parking.
Shutdown and Storage
▲ Lower implement, put tractor in park, turn off engine, and
remove the key.
▲ Secure implement using blocks and supports provided.
▲ Detach and store implement 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 implement, put tractor in park, turn off engine,
and remove key before performing maintenance.
▲ Make sure all system pressure is relieved.
▲ Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on
implement.
▲ 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 implement 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 implement functions.
▲ Operate machinery from the driver’s seat only.
▲ Do not leave implement unattended with tractor engine
running.
▲ Do not dismount a moving tractor. Dismounting a moving
tractor could cause serious injury or death.
▲ Do not stand between the tractor and implement during
hitching.
▲ Keep hands, feet and clothing away from moving parts.
▲ Watch out for wires, trees, etc., when folding and raising
implement. Make sure all persons are clear of working area.

Hitching Tractor to Implement
Check/Change Hitch Configuration 2013-
These instructions apply to LC40 models manufactured
in 2013. For 2014+ see page 14.
Choose a hitch option that is compatible with your tractor
3-point. The LC40 has two ASABE S217 / ISO 730-1
hitch configurations:
Category 3 (80 to 225 hp / 60 to 168 kW)
Category 4 (180 to 400 hp / 135 to 300 kW)
Changing between categories requires exchanging pins
and bushings at the implement hitch.
Refer to Figure 3 (showing only the hitch plates; depicting
Category 3 arm pins and bushings installed, and Category 3
link pin stored)
Category 3 Hitch Pins
1. Remove the Category 3 link (upper) pin from the
37
upper rear storage hole. Relocate it to the lower
holes of the upper hitch plates. The upper
1
Category 4 link pin may be left in the upper
41
plates.
2. At the rear of the lower hitch plates, remove two:
805-168C PIN HTCH 1.44X8.38 USBL
39
These are the smaller of the lower hitch pins.
3. Also remove four sets:
