OPERATION
CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.
PURGE TRANSMISSION
CAUTION: Never engage or disengage
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 devel-
oped during shipping of your tractor.
IMPORTANT: SHOULD YOUR TRANSMISSION 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 “TO TRANSPORT” in
this section of manual).
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
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.
TO START ENGINE (See Fig. 10)
When starting engine for the first time or if engine has run
out of fuel, it will take extra cranking time to move fuel from
the tank to the engine.
Depress clutch/brake pedal and set parking brake.
Place motion control lever in neutral (N) position.
Move attachment clutch to “DISENGAGED” position.
Move throttle control lever to choke (
) position for
cold engine start. For warm engine start, move throttle
control to fast ( ) position.
Insert key into ignition and turn key clockwise to “START”
position and release key as soon as engine starts. Do
not run starter continuously for more than fifteen
seconds per minute. If engine does not start after
several attempts, move throttle control to fast ( )
position, wait a few minutes and try again.
When engine starts, slowly move throttle control lever
to desired running speed.
Allow engine to warm up for a few minutes before
engaging drive or attachments.
IMPORTANT: COLD STARTING FOR HYDRO (BELOW
40°F) - AFTER STARTING ENGINE AND BEFORE
DRIVING, LET TRANSMISSION WARM UP FOR ONE (1)
MINUTE BY PLACING MOTION CONTROL LEVER IN
NEUTRAL (N) POSITION AND RELEASING CLUTCH/
BRAKE PEDAL.
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 Adjust-
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.
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 “TO TRANSPORT” 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 tractor is now purged and now ready for normal
operation.
MOWING TIPS
Tire chains cannot be used when the mower housing is
attached to tractor.
Mower should be properly leveled for best mowing
performance. 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 Fig.13).
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 select-
ing 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.
