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 finished
(See Fig. 10).
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 mowing 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.
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 first 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 five (5) seconds and release pedal. Depress
reverse drive pedal to full reverse position, hold for five
(5) seconds and release pedal. Repeat this procedure
three (3) times.
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.
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
engaged 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 five feet then
backwards for five feet. Repeat this driving procedure
three times.
Your transmission is now purged and now ready for normal
op er a tion.
