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
A blade pitch of 1/4 inch (6 mm) is recommended. A
pitch larger than 1/4 inch (6 mm) will result in less
power required, larger clippings, and a poorer quality
of cut. A pitch less than 1/4 inch (6 mm) will result
in more power required, smaller clippings and a better
quality of cut.
