DECK
The underside of mower deck should be cleaned
after each period of use as grass clippings, leaves,
dirt and other matter will accumulate. This ac­
cumulation of grass clippings, etc., is undesirable
as it will invite rust and corrosion and may cause
an uneven discharge of grass clippings at the next
cutting.
The deck may be cleaned by tilting the mower for­
ward or on its side and scraping clean with a
suitable tool or by washing with a stream of water
from a garden hose.
CAUTION
Do not direct the stream of water at
a hot engine as damage to the
engine may result.

ing oil.
