BATTERY

Your tractor has a battery charging system which is sufficient 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 necessary.

TO CLEAN BATTERY AND TERMINALS

Corrosion and dirt on the battery and terminals can cause the battery to “leak” power.

•Remove terminal guard.

•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 “CONNECT BATTERY” in the Assembly section of this manual).

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.

TRANSAXLE COOLING

The transmission fan and cooling fins should be kept clean to assure proper cooling.

Do not attempt to clean fan or transmission while engine is running or while the transmission is hot. To prevent pos- sible damage to seals, do not use high pressure water or steam to clean transaxle.

•Inspect cooling fan to be sure fan blades are intact and clean.

•Inspect cooling fins for dirt, grass clippings and other materials. To prevent damage to seals, do not use compressed air or high pressure sprayer to clean cool- ing fins.

TRANSAXLE PUMP FLUID

The transaxle was sealed at the factory and fluid mainte- nance is not required for the life of the transaxle. Should the transaxle ever leak or require servicing, contact your nearest authorized service center/department.
