Purge Transmission; Mowing Tips - Husqvarna YTH2148 Owner's Manual

OPERATION
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 lever 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 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.
PURGE TRANSMISSION
I CAUTION: Never engage or disengage I
A
freewheel lever while the engine is run-
ning.
To ensure proper operation and performance, it is recom-
mended that the transmission be purged before operating
tractor for the first time. This procedure will remove any
trapped air inside the transmission which may have de-
veloped during shipping of your tractor.
IMPORTANT: SHOULDYOURTRANSMISSlON REQUIRE
REMOVAL FOR SERVICE OR REPLACEMENT, IT
SHOULD BE PURGED AFTER REINSTALLATION
BEFORE OPERATING THE TRACTOR.
• Place tractor safely on level surface with engine off and
parking brake set.
• Disengage transmission by placing freewheel control
in freewheeling position (See"TOTRANSPORT"in this
section of manual).
• Sitting in the tractor seat, start engine. After the en-
gine is running, move throttle control to slow position.
With motion control lever in neutral (N) position, slowly
disengage clutch/brake pedal.
• Move motion control lever to full forward position and
hold for five (5) seconds. 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 parking brake.
• Engage transmission by placing freewheel control in
driving position (See 'q'OTRANSPORT" 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) position, slowly
disengage clutch/brake pedal.
• Slowly move motion control lever forward, after the
tractor moves approximately 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 transmission is now purged and now ready for
normal operation.
MOWING TIPS
• 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
machine. 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 Pig. 12).

FIG. 12
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.
