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. 9).
OPERATION
•      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.
WARM WEATHER STARTING (50° F and above)
•     When engine starts, move the throttle control to the 
fast position.
•      The attachments and ground drive can now be used. If 
the engine does not accept the load, restart the engine 
and allow it to warm up for one minute using the choke 
as described above.
COLD WEATHER STARTING ( 50° F and below)
•     When engine starts, allow engine to run with the 
throttle control in the choke position until the engine 
runs roughly, then move throttle control to fast posi-
tion. This may require an engine warm-up period from 
several seconds to several minutes, depending on the 
tem per a ture.
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.
•     Place the motion control lever in neutral.  
Re lease 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 also be used during the engine 
warm-up period after the transmission has been warmed 
up.
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
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 engine 
is running, move throttle control to slow position. With 
motion control lever in neutral (N) po si tion, slowly dis-
engage clutch/brake pedal. 
•      Move motion control lever to full forward position and 
hold for fi ve (5) seconds. Move lever to full reverse 
position and hold for fi ve (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 
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. 
With motion control lever in neutral (N) position, slowly 
disengage clutch/brake pedal.
•     Slowly move motion control lever forward, after the 
tractor moves approximately fi ve (5) feet, slowly move 
motion control lever to reverse position. After the trac-
tor moves approximately fi ve (5) feet return the mo-
tion 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 op er a tion.
