OPERATION
AUTOMATIC TRANSMISSION WARM UP
Before driving the unitincold 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 'q-O
ADJUST CARBURETOR" in the Service and Adjustments
section of this manual.
PURGE TRANSMISSION
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: SHOULD YOUR TRANSMISSION REQUIRE
REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD
BE PURGEDAFTER REINSTALLATIONBEFOREOPERATING
THE TRACTOR.
Place tractor safely in an area that is flat for approxi-
mately 80 feet in front of the tractor and set the parking
brake.
Sitting in the tractor seat, start engine. After the engine
is running, move throttle control to slow position. With
motion control lever in neutral (N) position, slowly dis-
engage clutch/brake pedal.
Slowly move motion control lever to full forward position
and hold for five (5) seconds, or approximately 40 feet.
Slowly move lever to full reverse position and hold for
five (5) seconds, or approximately 20 feet. After the
tractor moves approximately 20 feet in reverse return
the motion control lever to the neutral (N) position.
Your transmission is now purged and now ready for normal
operation.
MOWING TIPS
Mower should be properly leveledfor bestmowing per-
formance. See "TO LEVEL MOWER HOUSING" inthe
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 tothe rightof the
machine. This will result in a more even distributionof
clippings and more uniform cutting.
When mowinglargeareas, start by turningtotherightso
that clippingswill discharge away from shrubs, fences,
driveways, etc. After one or two rounds, mow in the
opposite direction making lefthand turns untilfinished
(See Fig. 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.
