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.
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.

HT1100-35 & HT1100-40 Table of Contents Index Important Safety Information
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 Terra Max using blocks and supports provided.
Detach and store Terra Max 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.

Introduction
The Terra Max has been designed with care and built by
skilled workers using quality materials. Proper setup,
maintenance, and safe operating practices will help the
customer get years of satisfactory use from the machine.
Description of Unit
The HT1100-35 & HT1100-40 Terra Max is a three section
“hybrid” tillage tool. Working width ranges from 20 to 30 feet.
The implement is designed to cut and size residue, till soil for
faster seedbed warming, break up soil crust on hard dried
fields while eliminating compaction layers. The front and rear
gangs may be adjusted from 0-8 degree angle, depending on
the aggressiveness desired. Various finishing attachments are
also available to further smooth, redistribute residue, kill
weeds, and break clods.
