Mowing Tips - Craftsman 917.28890 Operator's Manual

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).
_RGE 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-
gage parking brake.
AUTION: At any time, during step 4,
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 posi-
tion and hold for five (5) seconds and
release pedal. Repeat this procedure
three (3) times.
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).
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 extremely tall, it should be
mowed twice to reduce load and pos-
sible fire hazard from dried clippings.
Make first cut relatively high; the second
to the desired height.
• Do not mow grass when it is wet.
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 at-
tachment being used.
