Hourmeter
The hourmeter, which is located on the right front
of the body, displays operating time accumulated
while the PTO (blade drive) clutch is engaged.
Hourmeter
The hourmeter provides maintenance reminders
after certain hours of operation. The hourmeter
screen will start ashing the reminder one hour pri-
or to the recommended interval and will continue
until one hour after the recommended interval (two
hours). The hourmeter does not have a manual
reset function. Hourmeter maintenance remind-
ers are identied in the following chart.
NOTE: The blinking hour glass on the display
means that the meter is operating properly.

Walker and the engine manufacturers recom-
mend engine oil changes every 50 hours
in extremely dirty or dusty conditions or for
units with less than 100 hours annual use.
Transaxle Lockout Arms
The transaxle lockout arms disengage the transax-
les to permit freewheeling the tractor. This is used
to enable moving the machine without the engine
running (e.g., for service). There are two lockout
arm tabs, one for each transaxle, used to engaged
and disengaged the lockout feature. More infor-
mation about this feature is covered in “Transaxle
Lockout” on page 32.
NOTE: The transaxle lockout arm tabs should be
completely retracted against the chassis during
normal use, otherwise operation of the transaxle
may be erratic.
