WARMWEATHER STARTING (50° F and
above)
, When engine starts, slowly push choke
control in until the engine begins to run
smoothly. If the engine starts to run
roughly, pull the choke control out
slightly for a few seconds and then con-
tinue to push the control in slowly
, The attachments and ground drive can
now be used. If the engine does not ac-
cept the load, restart the engine and al -
low it to warm up for one minute using
the choke as described above°
COLD WEATHER STARTING (50 ° F and
below)
, 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,
pu_l the choke control out s_]ghtly 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:
• Be sure the tractor is on level ground.
° Place the motion control rover In neutral.
Release the parking brake and let the
clutch/brake slowly return to operating
position.
• Allow one minute for transmission to
warm up This can be done during the
engine warm up pedod.
• 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
puiled 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.

PURGE TRANSMISSION
_, CAUTION: Never engage or disen-
gage freewheel lever while the engine is
running.
To ensure proper operation and perfor-
mance, it is recommended that the trans-
mission be purged before operating trac-
tor for the first time. This procedure will re-
move any trapped air inside the transmis-
sion which may have developed during
shipping ol your tractor.
IMPORTANT: Should your transmission
require removal for service or replace-
ment, it should be purged after reinstal[a-
tion before operating the tractor.
• Place tractor safely on level surface
with engine off and parking brake set.
, Disengage transmission by ptacing
freewheel control in freewheeling posi-
tion (See "TO TRANSPORT" in this sec-
tion of manual).
• Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to slow position. With
motion control lever in neutral (N) posi-
tion, slowly disengage clutch/brake
pedal.
• Move motion control lever to full for-
ward position and hold for five (5) sec-
onds Move lever to full reverse position
and hold for five (5) seconds. Repeat
this procedure three (3) times.
NOTE: During this procedure there will
be no movement of drive wheels. The air
is being removed from hydraulic drive
system,
° Move motion control lever to neutral (N)
position. Shut off engine and set park-
ing brake.
o Engage transmission by placing free-
wheel control in driving position (See
"TO TRANSPORT" in this section of
manual)
° Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to half (1/2) speed. With
motion control lever in neutral (N) posi-
tion, slowly disengage clutch/brake
pedal.
° Slowly move motion control lever for-
ward; after the tractor moves approxi-
mately five (5) feet, slowly move motion
control lever to reverse position. After
the tractor moves approximately five (5)
feet return the motion control lever to
the neutral (N) position, Repeat this
procedure with the motion control lever
three (3) times.
Your tractor is now purged and ready
for normal operation_
