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 4,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.
Use Safety Chains
Use safety chains to help control drawn machinery should
it separate from tractor draw-bar or trailing nurse tank
hitch.
Use chain with a strength rating equal to or greater than
the gross weight of towed machinery.
Attach implement chain to tractor draw-bar support or
specified anchor location. Allow only enough slack in
chain for turns.
Replace chain if any links or end fittings are broken,
stretched or damaged.
Do not use safety chain for towing.

HT1100-20 - HT1100-30 Table of Contents Index Important Safety Information
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin, causing
serious injury. This Terra Max requires a Power-Beyond port,
which is always under pressure when the tractor is running.
Avoid the hazard by relieving pressure at other remote,
and shutting down tractor before connecting,
disconnecting or inspecting 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.
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.
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.
Transport Machinery Safely
Maximum transport speed for implement is 20 mph (32 kph),
13 mph (22 kph) in turns. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to swerve and
upset.
Do not tow an implement or nurse tank that weighs more
than 1.5 times the weight of towing vehicle.
Carry reflectors or flags to mark Terra Max in case of
breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting. Refer to transport
dimensions under “Terra Max Specifications and
Capacities” on page 36.
Do not exceed 20 mph. 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.
Reduce speed on rough roads.
Comply with national, regional and local laws.
Do not fold or unfold the Terra Max while the tractor is
moving.

Shutdown and Storage
Lower Terra Max, put tractor in park, turn off engine, and
remove the key.
Secure Terra Max using parking jack provided.
Detach and store Terra Max in an area where children
normally do not play.
Tire Safety
Tire changing can be dangerous. Employ 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.
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 implement, 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.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on Terra
Max.
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 Terra Max functions.
Operate machinery from the driver’s seat only.
Do not leave Terra Max unattended with tractor engine
running.
Do not stand between tractor and implement, or
implement and nurse tank, 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
Terra Max. Make sure all persons are clear of working
area.
Safety Decals
Safety Reflectors and Decals
Your implement comes equipped with all lights, safety
reflectors and decals in place. They were designed to help you
safely operate your implement.
Read and follow decal directions.
Keep lights in operating condition.
Keep all safety decals clean and legible.
Replace all damaged or missing decals. Order new decals
from your Great Plains dealer. Refer to this section for
proper decal placement.
When ordering new parts or components, also request
corresponding safety decals.
To install new decals:
1. Clean the area on which the decal is to be placed.
2. Peel backing from decal. Press firmly on surface, being
careful not to cause air bubbles under decal.
