HIGHLIGHTED INFORMATION

Walker Manufacturing recommends that any service
requiring special training or tools be performed by
an authorized Walker Mower Dealer.  There are sev-
eral general practices to be aware of in the area of
safety.  Most accidents associated with the oper-
ation or maintenance of a Walker product are
caused by disregarding basic safety precautions or
specific 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

 for the meanings of DANGER, WARN-

ING, CAUTION, IMPORTANT, and NOTE.

GLOSSARY

There are many terms that are either unique to this
equipment or that are used as acronyms.  The fol-
lowing terms and their definitions will help while us-
ing this manual:

DECK

 

is the mowing attachment mounted on

the front of the tractor which includes the carrier
frame, deck housing, blade drive gearboxes,
and cutter blades.

FORWARD SPEED CONTROL (FSC)
SWITCH
 controls the maximum forward speed
of the tractor; functioning as a cruise control.

GROUND DRIVE refers to the dual hydrostatic
transmissions which drive the main wheels.

LEFT HAND (LH) refers to the left-hand side of
the tractor when the operator is seated facing
forward from the operator position.

NEUTRAL LOCKOUT releases the hydrostatic
transaxles to permit freewheeling the tractor.

PISTOL GRIPS steer the tractor by controlling
the dual hydrostatic transaxles.

POWER TAKE-OFF (PTO) transmits engine
power to run the cutter blades.

RIGHT HAND (RH) refers to the right-hand side
of the tractor when the operator is facing for-
ward from the operator position. 

SIDE DISCHARGE (SD) mows but does not
collect the mowed material

.

TRACTOR is the prime mover, including the en-
gine, drive train, and controls to operate the
mower.

IDENTIFYING NUMBER LOCATIONS

The mower serial number is affixed to RH side of the
inside of the unit housing.  Model and serial numbers
are helpful when obtaining replacement parts and
