The objective of Harper Industries in designing the ATM 72 LC was to create a mowing
machine that could function safely and comfortably 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
several 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
situations.
However, we urge EXTREME CAUTION or
else your condence in these features get
you into trouble.
REMEMBER: The features of the ATM 72

Manual Leveling Switch – one is located
on the arm rest and the other on the ROPS.
Both of these switches perform the same
function. One is intended to be used while
in the operator’s seat and the other for when
standing behind the machine. They are used
to manually tilt the machine left or right.
Auto/Manual Leveling Switch – determines
if the machine is leveled automatically using
the signal from the inclinometer module or
leveled only using the manual leveling switch.
Inclinometer Module – senses if the machine is off center/vertical. The machine can
lean to either side up to 34° before reaching
its limit.
• The inclinometer module includes a
dual axis (XY) accelerometer. It
measures the force caused by
movement of the sensor (accelera tion). Gravity puts a force on the
sensing elements that can be mea sured. The sensor is an analog device
with a voltage for X and a voltage for
Y. The module uses the voltage
outputs from the sensor to determine
the angle of the machine.
• When the inclinometer module mea sures an angle 4 degrees or greater
from center, it sends a +12 V signal to
the hydraulic valve to operate the
appropriate leveling cylinder to return
the machine to an upright position.
SAFETY WARNING!
Do not leave ATM 72LC unattended, or
attempt any service or inspection unless
the machine has come to a complete stop
and the engine has been shut off.
