Mowing Tips - Craftsman 917.28828 Operator's Manual

This may require an engine warm-up
period from several seconds to several
minutes,dependingon 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 position.
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 transmis-
sion 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 CAR BU RETO R" in the Service
and Adjustments section of this manual).
PURGE TRANSMISSION
_,CAUTION: Never engage or dis-
engage freewheel lever while the engine
is running.
To ensure proper operation and per-
formance, it is recommended that the
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.
2. Disengage transmission by placing
freewheel control in disengaged posi-
tion (See "TO TRANSPORT" in this
section of manual).
3. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to slow position. Disen-
_Lgage parking brake.
AUTION: At any time there may be
movement of the drive wheels.
4. Depress forward drive pedal to full forward
position and hold for five (5) seconds and
release pedal. Depress reverse drive
pedal to full reverse position and hold
for five (5) seconds and release pedal.
Repeat this procedure three (3) times.
5. Shutoff engine and set parking brake.

6. Engagetransmission by placing freewheel
control in engaged position (See "TO
TRANSPORT" in this section of manual).
7. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to half (1/2) speed.
Disengage parking brake.
8. Drive tractor forward for approximately
five feet then backwards for five feet.
Repeat this driving procedure three times.
Your transmission is now purged and now
ready for normal operation.
MOWING TIPS
• Tire chains cannot be used when the
mower housing is attached to tractor.
• Mower should be properly leveled for best
mowing performance. See "TO LEVEL
MOWER HOUSING" in the Service and
Adjustments section of this manual.
• The left hand side of mower should be
used for trimming.
• Drive so that clippings are discharged
onto the area that has already been cut.
Have the cut area to the right of the tractor.
This will result in a more even distribution
of clippings and more uniform cutting.
• When mowing large areas, start by
turning to the right so that clippings will
discharge away from shrubs, fences,
driveways, etc. After one or two rounds,
mow in the opposite direction making
left hand turns until finished.
• If grass is extremelytall, it should be mowed
twice to reduce load and possible fire haz-
ard from dried clippings. Make first cut rela-
tively high;the second to the desired height.
• Do not mow grasswhen it iswet. Wet grass
will plug mower and leave undesirable
clumps. Allow grass to dry before mowing.
• Always operate engine at full throttle
when mowing to assure better mowing
performance and proper discharge of
material. Regulate ground speed by
selecting a low enough speed to give
the mower cutting performance as well
as the quality of cut desired.
• When operating attachments, select a
ground speed that will suit the terrain and
give best performance of the attachment
being used.
