WARM WEATHER STARTING (50° F and
above)
7. When engine starts, slowly push choke
control in until the engine begins to
run smoothly. If the en gine starts to
run roughly, pull the choke control out
slightly for a few seconds and then
continue to push the control in slowly.

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-

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
sec onds to several minutes, depending
on the temperature.
NOTE: In extreme cold conditions, if
engine will not start you may need to dis-
engage the motion drive belt as follows:
1. Be sure parking brake is engaged.
2. Remove retainer spring from the drive
belt tension handle to relieve belt ten-
sion.
3. Start engine and allow it to warm up for
three (3) minutes.
4. Shut-off engine and engage parking
brake.
5. Engage drive belt tension handle and
replace the retainer spring.
AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weath er,
the trans mis sion should be warmed up as
follows:
1. Be sure the tractor is on level ground.
PURGE TRANSMISSION
CAUTION: Never engage or dis en gage
freewheel lever while the engine is run-
ning.
To ensure proper operation and per-
for mance, it is rec om mend ed that the
trans mis sion be purged before operating
trac tor for the fi rst time. This procedure will
remove any trapped air inside the trans-
mis sion which may have de vel oped dur ing
shipping of your tractor.
IMPORTANT: Should your transmission
require removal for service or re place -
ment, it should be purged after re in stal l-
a tion before operating the tractor.
1. Place tractor safely on level surface
with engine off and parking brake set.
2. Disengage transmission by plac-
ing freewheel control in disengaged
po si tion (See “TO TRANSPORT” in this
section of manual).
3. Sitting in the tractor seat, start en gine.
After the engine is running, move
throttle control to slow position. Disen-
gage parking brake.
4. Move motion control lever to full
for ward position and hold for fi ve (5)
seconds. Move lever to full reverse
position and hold for fi ve (5) seconds.
Repeat this procedure three (3) times.
NOTE: During this step there will be no
movement of drive wheels. The air is being
removed from hydraulic drive sys tem.
5. Move motion control lever to neutral
(N) position. Shutoff engine and set
parking brake.
6. Engage transmission by placing free-
wheel control in engaged position (See
“TO TRANSPORT” in this sec tion of
manual).
2. Place the motion control lever in
neu tral. Release the parking brake and
let the brake slowly return to operating
position.
3. Allow one minute for trans mis sion to
warm up. This can be done during the
en gine warm up period.
• The attachments can be used during
the engine warm-up period after the
trans mis sion has been warmed up and
may require the choke con trol be pulled
out slight ly.
NOTE: If at a high altitude (above 3000
feet) or in cold temperatures (below 32 F)
the car bu re tor fuel mixture may need to
be adjusted for best engine performance
(see “TO ADJUST CARBURETOR” in the
Service and Ad just ments section of this
