COLD WEATHER
STARTING ( 50 ° F and

7. When engine starts, allow engine
to run with the throttle control in the
choke position until the engine runs
roughly, then move throttle control
to fast position. This may require an
engine warm-up period from several
seconds to several minutes, depending
on the temperature.
AUTOMATIC TRANSMISSION
WARM UP
Before driving the unit in cold weather,
the transmission
should be warmed up as
follows:
1. Be sure the tractor is on level ground.
2. Place the motion control lever in
neutral. Release the parking brake
and let the clutch/brake
slowly return
to operating position.
3. Allow one minute for transmission
to
warm up. This can be done during
the engine warm up period.
• The attachments
can also be used dur-
ing the engine warm-up period after the
transmission
has been warmed up.
NOTE:
If at a high altitude (above 3000
feet) or in cold temperatures
(below 32 F)
the carburetor fuel mixture may need to
be adjusted for best engine performance.

ment, it should be purged after reinstall-
ation before operating the tractor.
