BEFORE STARTING THE ENGINE

CHECK ENGINE OIL LEVEL

The engine in your tractor  has been 
shipped, from the factory, already fi lled 
with sum mer weight oil.  
1.   Check engine oil with tractor on level 

ground.  

2.   Remove oil fi ll cap/dipstick and wipe 

clean, reinsert the dipstick and screw 
cap tight, wait for a few seconds, re-
move and read oil level.  If nec es sary, 
add oil until  “FULL” mark on dipstick is 
reached.  Do not overfi ll.

•   For cold weather operation you should 

change oil for easier starting (See “OIL 
VISCOSITY CHART” in the Main te -
nance sec tion of this man u al).   

•   To change engine oil, see the Main te -

nance section in this manual.

ADD GASOLINE 

•   Fill fuel tank to bottom of fi ller neck. Do 

not overfi ll.  Use fresh, clean, regular 
un lead ed gasoline with a minimum of 
87 octane.  (Use of  leaded gasoline will 
increase carbon and lead oxide deposits 
and reduce valve life).  Do not mix oil 
with gasoline.  Purchase fuel in quan-
 ti ties that can be used within 30 days to 
assure fuel freshness.

 CAUTION:

  Wipe off any spilled oil or 

fuel.  Do not store, spill or use gasoline 
near an open fl ame.

IMPORTANT:

  When operating in temper-

atures below32°F(0°C), use fresh, clean 
winter grade gas o line to help insure good 
cold weather start ing.

 CAUTION:

  Alcohol blended fuels 

(called gasohol or using ethanol or metha-
nol) can attract moisture which leads to 
separation and for ma tion of acids during 
storage.  Acidic gas can damage the fuel 
system of an engine while in storage.  To 
avoid engine problems, the fuel system 
should be emptied before stor age of 30 
days or longer.  Drain the gas tank, start 
the engine and let it run until the fuel lines 
and carburetor are empty.  Use fresh fuel 
next season.  See Storage In struc tions for 
additional information.  Never use engine 
or carburetor cleaner products in the fuel 
tank or permanent damage may occur.

TO START ENGINE

When starting the engine for the fi rst time 
or if the engine has run out of fuel, it will 
take extra cranking time to move fuel from 
the tank to the engine.
1.   Sit on seat in operating position, 

depress clutch/brake pedal and set 
parking brake.

2.   Place gear shift lever in neutral (N) 

position.

3.   Move attachment clutch to dis en gaged 

po si tion.

4.   Move throttle control to choke po si tion.

NOTE: 

 Before starting, read the warm 

and cold starting procedures below.
5.   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 fi fteen 
sec onds per minute. If the engine does 
not start after several attempts, move 
throt tle control to fast position, wait a few 
minutes and try again. If engine still does 
not start, move the throttle control back to 
the choke position and retry.

WARM WEATHER STARTING (50° F and 
above)
6.   When engine starts, move the throt tle 

control to the fast position.

•   The attachments and ground drive can 

now be used. If the engine does not 
accept the load, restart the en gine and 
allow it to warm up for one minute using 
the choke as de scribed above.

COLD WEATHER STARTING ( 50° F and 
below)
6.   When engine starts, leave throttle control 

in choke position until engine warms up 
and begins to run roughly. Once rough 
running begins, im me di ate ly move the 
throttle control to the fast position. Engine 
warm-up may take from several seconds 
to several minutes (the colder the tem-
 per a ture, the longer the warm-up).

•   The attachments can also be used dur-

ing the engine warm-up period.

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).
