Checking Tires

•Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber.

•Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

Drive Wheels

Check rear drive wheels each time before you mow to be sure they move freely.

The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels.

If necessary to clean the rear drive wheels, be sure to clean both front wheels.

1.Remove hubcaps, locknuts and washer.

2.Remove wheels from wheel adjusters.

3.Remove any trash or grass cuttings from inside the dust cover, pinion and/or drive wheel gear teeth.

4.Put wheels back in place

NOTE: If after cleaning, the drive wheels do not turn freely, contact a qualified service
