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.

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.
