Husqvarna 917.27909 - Manual (Page 15)

OPERATION
WARM WEATHER 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 continue to push the control in
slowly.
• The attachments and ground drive can now be used. If
the engine does not accept the load, restart the engine
and allow 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 engine 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.
• The attachments can be used during the engine warm­
up period 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.
MOWING TIPS
• Tire chains cannot be used when the mower housing
is attached to tractor.
• Mower should be properly leveled for best mowing per­
formance. See ‘TO LEVEL MOWER HOUSING” in the
Service and Adjustments section of this manual.
• The left hand side of mower should be used for trim­
ming.
• Drive so that clippings are discharged onto the area
that has 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
(See Fig. 11).
If grass is extremely tall, it should be mowed twice to
reduce load and possible fire hazard from dried clip­
pings. 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 mow­
ing
to assure better mowing performance and proper
discharge of material. Regulate ground speed by se­
lecting a low enough gear 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.
