MULCHING OPERATION (OPTIONAL)
The special mulching blades and baffles will allow the
grass clippings to be cut many times to reduce their
size. As the grass falls onto the lawn,it disperses into
the grass and will not be noticed. Also, the mulched
grass biodegrades quickly and provides nutrients for
the lawn.
• Always operate engine at full throttle when
mulching to assure the best cutting action of the
blades.
• For best performance, set the height of your
mower deck so that no more than 1/3 of the total
grass length is removed at any one time.
• Grass should be cut when it is dry, not when it is
wet from dew, rain or from watering. Wet grass
tends to pack inside mower pan and will not
disperse evenly.
• If grass does not disperse evenly, it is possible
that too much grass is being removed per cutting,
grass is too wet or travel speed is too fast.
• This mulcher is not recommended for newly
seeded lawns. A new lawn has much softer
blades of grass and a higher moisture content.
New lawns should be cut with conventional side
discharge or bagging for the first few mowings.
