ATM 162
Introduction
The objective of Harper Industries in design-
ing the ATM 162 was to create a mowing ma-
chine that could function safely and comfort-
ably on slopes and inclines. The result was an
All-Terrain Mower that will automatically adjust
itself to keep the operator in a vertical position
on all slopes up to 34 degrees.
Driving with an automatic leveling device will
be a new and different experience. After sev-
eral minutes of driving, the smooth control and
sturdy feel will become comfortable to you.
The security of always sitting upright and the
feel of powerful, positive traction will give you
condence and comfort in most mowing situ-
ations. However, we urge EXTREME CAU-
TION lest your condence in these features
get you into trouble. Please remember that
the features of the ATM 162 cannot replace
good common sense.
We here at Harper Industries would like to
thank you for purchasing our All-Terrain Mow-
er 162. In this Service and Parts Manual, we
will give you all the basic and technical infor-
mation you should need to be able to under-
stand, service, and look at your new Harper
Industries’ ATM 162. After thoroughly reading
this manual, you should be able to navigate
your way around and possibly even be able to
service your ATM 162 yourself.
In the rst part of this manual, we take you
through the general safety guidelines and
maintenance information. This information
should provide you with all you need to keep
your mower running at its best, but if some-
thing should go wrong that you do not under-
stand, you should have it serviced by one of
our knowledgeable technicians. NOTE: If you
do not know the diagnosis of the machine DO
NOT attempt to x it because you could void
your warranty.
The second part of this manual is parts, and in
it, we give you diagrams of all the parts of the
ATM 162 and how they relate to each other.
This should assist you with part numbers, as-
sembly, and location of all parts of the mower.
We have also inserted a troubleshooting for
some of the more frequent problems that oc-
cur. We hope that you enjoy your Harper In-
dustries’ ATM 162.

result in voidance of warranty, product
malfunction or possible injury.
Before Operation
Before starting the machine, visually
inspect all nuts, bolts and other
fasteners to see that they are properly
secured.
Nuts, bolts, screws and ttings should
be inspected after the rst hour of op-
eration and every 8 to 10 hours there-
after for proper tightness.
Make sure all belts and hoses are in
good condition. Replace if necessary.
Tire pressure should be at
supplier's specifications equal in all
three drive tires.
Clear all foreign objects such as rocks,
bottles or other hard materials that lay
in the area to be mowed.
Use steps and walkway to access cab.
Do not walk across decks.
During Operation
While operating the equipment, make
sure that no foreign objects such as
rocks, bottles or other hard materials
pass under the deck of the mower.
If an object should strike the blades
causing an unusual noise or vibration,
shut the engine off immediately and
allow it to come to a complete stop.
Take all prescribed safety precautions
and do the following:
1) Inspect for damage.
2) Check for wire or string around
the blades
2) Repair or replace damaged
parts.
3) Tighten any loose fasteners or
parts.

Safety Decals
If safety related or instructional decals
become illegible or are removed, re-
place them immediately.
If parts are replaced, make sure all
safety related or instructional decals
are present before the equipment is
operated again.
New decals may be obtained from
your local Harper Dealer.
Hydraulics
To prevent serious injury or death:
Relieve pressure on system before
repairing, adjusting or disconnecting
any hydraulic hose or tting.
Wear proper hand and eye protection
when searching for leaks.
Use wood or cardboard instead of
hands when looking for leaks.
Keep all hoses, ttings and compo-
nents in good repair.
Do not use any type of heat or ame
(welding, soldering, cutting torch, etc.)
near pressurized hydraulic lines.
SAFETY WARNING!
HIGH-PRESSURE FLUID HAZARD!
Escaping uid under pressure can pen-
etrate skin causing serious injury or death.
SAFETY WARNING!
Always keep a re extinguisher with the
ATM 162 during operation and service.
Diesel Fuel
Always use an approved container for
transporting diesel fuel.
Do not allow open ames or sparks
while performing maintenance or refu-
eling.
Never remove fuel tank cap or add
fuel when engine is running or while it
is hot.
Only use ultra low sulfer diesel.
Never ll fuel tank indoors. Fumes are
heavy and will sink to the lowest point,
collect and become hazardous.
Wipe up spilled fuel immediately.
Do not store fuel in a room with an ap-
pliance that has a gas pilot or electri-
cal switch that may cause sparks.
Always store diesel outside in a safe-
ty can (a can with ame arrestor and a
pressure relief valve in pour spout).
Never store the equipment with fuel in
the tank inside a building where fumes
may reach an open ame or spark.
Allow the engine to cool before storing
in any enclosure.
Be certain to provide adequate ventila-
tion if an engine must be run indoors -
exhaust fumes are dangerous.
SAFETY WARNING!
Diesel fuel is extremely ammable and can
be highly explosive.
SAFETY WARNING!
To prevent possible eye injury, always wear
SAFETY GLASSES while operating or ser-
vicing the equipment.
