you cannot achieve brake action and free wheel rotation
contact your service dealer immediately.

Check all belts after every 50 operating hours or monthly,
whichever occurs first. Look for dirt, wear, cracks, and
signs of overheating.

brake, stop the engine, remove the key, and disconnect
the spark plug wire from the spark plug.
2. Remove the top bolt securing idler support and idler

when cutting grass, frayed belt edges, burn marks, and
cracks are signs of a worn drive belt. Replace the mower
drive belt if any of these conditions are evident.

brake, stop the engine, remove the key, and disconnect
the spark plug wire from the spark plug.
