out. (Fig. 35)
To get a good result
Always use a sharp blade. A blunt blade gives an
irregular result and the cut surface of the grass
becomes yellow. A sharp blade also uses less
energy than a blunt blade.
Do not cut more than ⅓ of the length of the grass.
Cut first with the cutting height set high. Examine the
result and lower the cutting height to an applicable
level. If the grass is very long, drive slowly and cut 2
times if necessary.
Cut in different directions each time to prevent
stripes in the lawn.
Keep the cutting cover clean. Buildup from grass
and dirt on the inner side of the cutting cover can
decrease the cutting result. Refer to
To clean the
inner surface of the cutting cover on page 12
.
