AUTOMATIC TRANSMISSION WARM UP
• Before driving the unit in cold weather, the trans mis sion
should be warmed up as follows:
• Be sure the tractor is on level ground.
• Release the parking brake and let the brake slowly
return to operating po si tion.
• 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 con trol be pulled out
slight ly.
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 Ad just ments
section of this manual.
PURGE TRANSMISSION
CAUTION: Never engage or disengage
freewheel lever while the engine is run-
ning.
To ensure proper operation and performance, it is rec om -
mend ed that the transmission be purged before operating
tractor for the fi rst time. This procedure will remove any
trapped air inside the transmission which may have de-
vel oped during shipping of your tractor.
IMPORTANT: SHOULD YOUR TRANSMISSION RE QUIRE
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 "TO TRANSPORT" in this
section of manual).
• Sitting in the tractor seat, start engine. After the en-
gine is running, move throttle control to slow position.
Dis en gage parking brake
• Depress forward drive pedal to full forward position,
hold for fi ve (5) seconds and release pedal. Depress
reverse drive pedal to full reverse position, hold for fi ve
(5) seconds and release pedal. 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.
• Shut- off engine and set parking brake.
• Engage transmission by placing freewheel control in
driving position (See "TO TRANSPORT" in this sec tion
of manual).
• Sitting in the tractor seat, start engine. After the engine
is running, move throttle control to half (1/2) speed.
Disengage parking brake.
• Drive tractor forward for approximately fi ve feet then
backwards for fi ve feet. Repeat this driving procedure
three times.
• Your tractor is now purged and now ready for normal
operation.
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 dis tri bu tion 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 fi nished
(See Fig. 12).
• If grass is extremely tall, it should be mowed twice to
reduce load and possible fi re hazard from dried clip-
pings. Make fi rst 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
dis charge of material. Regulate ground speed by se-
lect ing a low enough gear to give the mower cut ting
per for mance 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 tach ment being used.
