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. 3. Remove filler plug from transaxle. Oil level must be even with plug threads. If necessary, fill with SAE 30 motor oil, API SG-SL.
Replace filler plug. 4. Reassemble wheel to hub. G O ,. _- Transaxle Filler Plug 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.

Select the oil's SAE viscosity grade according to your expected operating temperature. BATTE RY 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.

Check the crankcase oil level before start- ing the engine and after each eight (8) hours of operation.
TO CHANGE ENGINE OIL Corrosion and dirt on the battery and terminals can cause the battery to "leak" power. 1. Remove terminal guard. 2. Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor. 3. Rinse the battery with plain water and dry. 4. Clean terminals and battery cable ends with wire brush until bright. 5. Coat terminals with grease or petro- leum jelly. 6. Reinstall battery (See "REPLACING BATTERY" in the SERVICE AND AD- 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.
