Check for bent blades; refer to

5.
Cut grass in a test area to determine if all cutting units
are cutting at the same height.
6.
When cutting unit adjustments are still needed, find a
flat surface using a 2 m (6 foot) or longer straight edge.
7.
To ease measuring blade plane, raise the height of cut
to the highest position; refer to
.
8.
Lower cutting unit onto the flat surface. Remove the
covers from the top of the cutting units.
9.
Rotate the blade on each spindle until the ends face
forward and backward.
10.
Measure from the floor to the front tip of the cutting
edge.

Adjust the 3 mm (1/8 inch) shims on the castor fork(s)
to match the height of cut to decal (

Operating Tips
Mow When Grass Is Dry
Mow either in the late morning to avoid the dew, which causes
grass clumping, or in late afternoon to avoid the damage
that can be caused by direct sunlight on the sensitive, freshly
mowed grass.
Select the Proper Height-of-Cut Setting
to Suit Conditions
Remove approximately 25 mm (1 inch) or no more than 1/3
of the grass blade when cutting. In exceptionally lush and
dense grass, you may have to raise the height-of-cut to the
next setting.
Mow at Proper Intervals
Under most normal conditions you will need to mow
approximately every 4 or 5 days. But remember, grass grows
at different rates at different times. This means that in order
to maintain the same height of cut, which is a good practice,
you will need to cut more frequently in early spring; as the
grass growth rate slows in mid summer, cut only every 8 or
10 days. If you are unable to mow for an extended period due
to weather conditions or other reasons, mow first with the
height of cut at a high level; then mow again 2 or 3 days later
with a lower height setting.
Always Mow with Sharp Blades
A sharp blade cuts cleanly and without tearing or shredding
the grass blades like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases.
After Operating
To ensure optimum performance, clean the underside of the
mower housing after each use. If residue is allowed to build
up in the mower housing, cutting performance will decrease.
Cutting Unit Pitch
We recommend a blade pitch of 13 mm (1/2 inch). A
pitch larger than 13 mm (1/2 inch) will result in less power
required, larger clippings, and a poorer quality of cut. A pitch
less than 13 mm (1/2 inch) will result in more power required,
smaller clippings and a better quality of cut.
