•         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).

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 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 en-

gine 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 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 

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.

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 neu tral.  

Re lease the parking brake and let the clutch/
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 Adjustments 
section of this manual.

•     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 
tractor moves approximately fi ve (5) feet return the 
motion 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.

•      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.
