•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 balancer.)

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.

Your tractor has a battery charging system which is sufficient for normal use. How-

ever, 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 necessary.

TO CLEAN BATTERY AND TERMINALS

Corrosion and dirt on the battery and termi- nals can cause the battery to "leak" power.

1.Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor.

2.Rinse the battery with plain water and dry.

3.Clean terminals and battery cable ends

with wire brush until bright.

4.Coat terminals with grease or petro- leum jelly.

5.Reinstall battery (See "REPLACING BATTERY" in the SERVICE AND AD-

JUSTMENTS section of this manual).

TRANSAXLE COOLING

Keep transaxle free from build-up of dirt and chaff which can restrict cooling.

V-BELTS

Check V-belts for deterioration and wear after 100 hours of operation and replace if necessary. The belts are not adjustable.

Replace belts if they begin to slip from wear.

ENGINE

LUBRICATION

Only use high quality detergent oil rated with API service classification SG-SL. Se-

lect the oil's SAE viscosity grade according to your expected operating temperature.

SAE VISCOSITY GRADES

-30-20 =100

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils

(5W30, 10W30 etc.)improve starting in cold weather, the oils will result in in- creased oil consumption when used above 32°E Check your engine oil level more frequently to avoid possible engine dam- age from running low on oil.

Change the oil after every 25 hours of op- eration or at least once a year if the tractor is not used for 25 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 CHANGE ENGINE OIL

Determine temperature range expected

before oil change. All oil must meet API

service classification SG-SL.

•Be sure tractor is on level surface.

•Oil will drain more freely when warm.

•Catch oil in a suitable container.

1.Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil.

2.Remove yellow cap from end of drain valve and install the drain tube onto the

fitting.

Oil Drain Valve

3.Unlock drain valve by pushing inward slightly and turning counterclockwise.

4.To open, pull out on the drain valve.

5.After oil has drained completely, close and lock the drain valve by pushing inward and turning clockwise until the pin is in the locked position as shown.
