General Information
HIGHLIGHTED INFORMATION
Walker Manufacturing recommends that any ser-
vice requiring special training or tools be performed
by an authorized Walker Mower dealer. There are
several general practices to be aware of in the
area of safety. Most accidents associated with the
operation or maintenance of a Walker Mower are
caused by disregarding basic safety precautions or
specic warnings. Such accidents, in most cases,
can be prevented by being aware of the dangers
present.
Information of special importance has been high-
lighted in bold type in this manual. Refer to Safety
Instructions on page 10 for the meanings of
DANGER, WARNING, CAUTION, IMPORTANT,
and NOTE.
GLOSSARY
There are many terms that are either unique to this
equipment or that are used as acronyms. The
following terms and their denitions will help while
using this manual:
●DECK is the mowing attachment mounted on
the front of the tractor which includes the
carrier frame, deck housing, belt or gear drive
components, and cutter blades.
●FORWARD SPEED CONTROL (FSC) controls
the maximum forward speed of the tractor;
functioning as a cruise control.
●GRASS HANDLING SYSTEM (GHS®) collects
mowed material and deposits it in the catcher.
●GRASS-PAK®SWITCH is mounted on the
grass delivery spout (in the catcher) and
activates the “full” signal horn when the grass
catcher is full.
●GROUND DRIVE refers to the dual hydrostatic
transmissions which drive the main wheels.
●HYDROSTATIC TRANSMISSION transmits
and controls power from the ground drive belt
to the main drive wheel.
●LEFT HAND (LH) refers to the left-hand side
of the tractor when the operator is seated
facing forward in the tractor seat.
●POWER TAKE-OFF (PTO) transmits engine
power to run the cutter blades and GHS
blower.
●POWERFIL® spreads the mowed material
throughout the interior of the grass catcher by
an oscillating delivery spout.
●RIGHT HAND (RH) refers to the right-hand
side of the tractor when the operator is seated
facing forward in the tractor seat.
●SIDE DISCHARGE (SD) discharges mowed
material from the right side of the mower deck.
●STEERING LEVERS steer the tractor by
controlling the dual hydrostatic transmissions.
●TRACTOR is the prime mover, including the
engine, drivetrain, operator seat, and controls
to operate the mower.
●TRANSMISSION LOCKOUT releases the
hydrostatic transmissions to permit freewheel-
ing the tractor.
IDENTIFYING NUMBER LOCATIONS
The tractor serial number plate is axed to the
tractor body just below the left rear corner of the
seat. The mower deck serial number plate is
axed alongside the angle iron framing on the LH
side of the LH mower blade drive. Model and
serial numbers are helpful when obtaining replace-
ment parts and maintenance assistance. For
ready reference, please record these numbers in
the space provided.
