THINGS TO KNOW BE FORE YOU ASSEMBLE OR OPERATE YOUR LAWN
MOW ER
Do I have a side or rear discharge lawn
mower?
Look for the grass discharge opening on
your mower. If the opening is on the right
side of the mower housing, it is a side
discharge mower. If the opening is at the
back of the mower housing, it is a rear discharge mower. Only rear discharge lawn
mowers have a grass catcher in clud ed with
the mower. Approved grass catchers for
side discharge mow ers may be purchased
from your nearest au tho rized dealer.
Do I have a mulching lawn mower?
Look for the grass discharge opening on
your mower. Raise the discharge guard
(rear door on rear discharge mowers). If
the opening is closed off by a plate, then
your lawn mower is mulcher ready. To
convert to a discharging mower, see the
Operation section of this manual.
FRONT
What is the right and left side of the
lawn mower?
When right hand (RH) or left hand (LH) is
mentioned in this man ual, it means when
you are in the operating po si tion (stand ing
be hind the handle).
What kind of engine is on my lawn
mower?
When learning how to operate your new
lawn mower, you will need to know what
