ATM 72 LC
R
Introduction
The objective of Harper Industries in design-
ing the ATM 72 was to create a mowing ma-
chine that could function safely and comfort-
ably on slopes and inclines. The result is 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
condence and comfort in most mowing situ-
ations. However, we urge EXTREME CAU-
TION lest your condence in these features
get you into trouble.
REMEMBER: The features of the ATM 72
cannot replace good common sense.
Operating Guide

a period of time, from internal hydrau-
lic leakage. This will not affect operat-
ing leveling during mowing operations.
• COLD WEATHER starting: Turn key to
Pre-heat, light on dash will light, hold
until the light goes out, then start. The
engine is designed for easy starting
