BATTERY
Your tractor has a battery charging system which is suf fi cient
for normal use. However, periodic charging of the battery
with an automotive charger will extend its life.
Keep battery and terminals clean.
Keep battery bolts tight.
Keep small vent holes open.
Recharge at 6-10 amperes for 1 hour.
NOTE: The original equipment battery on your tractor is
maintenance free. Do not attempt to open or remove caps
or covers. Adding or checking level of electrolyte is not
nec es sary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to “leak” power.
Disconnect BLACK battery cable first then RED bat-
tery cable and remove battery from tractor.
Rinse the battery with plain water and dry.
Clean terminals and battery cable ends with wire brush
until bright.
Coat terminals with grease or petroleum jelly.
Reinstall battery (See “REPLACING BATTERY” in the
Service and Adjustment sec tion of this manual).

MAINTENANCE
V-BELTS
Check V-belts for deterioration and wear after 100 hours and
replace if necessary. The belts are not adjustable. Re place
belts if they begin to slip from wear.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and chaff which
can restrict cooling.

ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SG-SL. Select the oil’s SAE viscosity grade
according to your expected operating temperature.
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, they will result in increased
oil consumption when used above 32°F. Check your engine
oil level more frequently to avoid possible engine damage
from running low on oil.
Change the oil after every 50 hours of operation or at least
once a year if the tractor is not used for 50 hours in one
year.
Check the crankcase oil level before starting the engine
and after each eight (8) hours of operation. Tighten oil fill
cap/dipstick securely each time you check the oil level.

TO SHARPEN BLADE (See Fig. 11)
NOTE: We do not recommend sharpening blade - but if
you do, be sure the blade is balanced.
Care should be taken to keep the blade balanced. An un-
bal anced blade will cause excessive vibration and even tual
dam age to mower and engine.
The blade can be sharpened with a file or on a grind-
ing wheel. Do not attempt to sharpen while on the
mower.
To check blade balance, you will need a 5/8" diameter
steel bolt, pin, or a cone balancer. (When using a
cone balancer, follow the instructions supplied with
bal anc er.)
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
Slide blade on to an unthreaded portion of the steel bolt
or pin and hold the bolt or pin parallel with the ground.
If blade is balanced, it should remain in a horizontal
position. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.
