COLD WEATHER STARTING (50 ° F and
below)
7. When engine starts, slowly push choke
control in until the engine begins to run
smoothly. Continue to push the choke
control in small steps allowing the en-
gine to accept small changes in speed
and load, until the choke control is fully
in. If the engine starts to run roughly,
pull the choke control out slightly for a
few seconds and then continue to push
the control in slowly. 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. Release the parking brake and let the
brake slowly return to operating posi-
tion.
3. Allow one minute for transmission to
warm up. This can be done during the
engine warm up period.
The attachments can be used during
the engine warm-up period after the
transmission has been warmed up and
may require the choke control be pulled
out slightly.
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
(see "TO ADJUST CARBURETOR" in the
Service and Adjustments section of this
manual).

CAUTION: Never engage or dis-
engage freewheel lever while the engine

transmission be purged before operating
tractor for the first time. This procedure will
remove any trapped air inside the trans-
mission which may have developed during
shipping of your tractor.
IMPORTANT: Should your transmission
require removal for service or replace-
ment, it should be purged after reinstall-
ation before operating the tractor.
1. Place tractor safely on a level surface
- that is clear of objects and open - with
engine off and parking brake set.

freewheel control in disengaged posi-
tion (See "TO TRANSPORT" in this
section of manual).
3. Sitting in the tractor seat, start engine.

tion and hold for five (5) seconds and
release pedal. Repeat this procedure

5. Shutoff engine and set parking brake.
6. Engage transmission by placing free-
wheel control in engaged position (See
"TO TRANSPORT" in this section of
manual).
