Operating your lawn mower, Warning – Troy-Bilt 420 User Manual

Page 9

WARNING: If you strike a foreign object,
stop the engine. Remove wire from the
spark plug, thoroughly inspect mower for

any damage, and repair damage before restarting
and operating. Extensive vibration of mower during
operation is an indication of damage. The unit
should be promptly inspected and repaired.

Using as Mulcher

For mulching grass, remove the grass catcher and side
discharge chute from the mower. For effective mulching,
do not cut wet grass. If the grass has been allowed to
grow in excess of four inches, mulching is not recom-
mended. Use the grass catcher to bag clippings instead.

Using Grass Catcher

You can use the grass catcher to collect clippings while
you are operating the mower. Refer to setup section for
instructions on attaching the grass catcher.

Starting Engine

WARNING: Be sure no one other than the
operator is standing near the lawn mower

while starting engine or operating mower. Never
run engine indoors or in enclosed, poorly ventilated
areas. Engine exhaust contains carbon monoxide, an
odorless and deadly gas. Keep hands, feet, hair and
loose clothing away from any moving parts on engine
and lawn mower.
Follow the set of instructions pertaining to your unit.
Refer to engine manual for help with the engine.
