The flow divider is for use in low speed range only. When approaching an area known to cause wheel spin, depress and hold flow divider switch until completely past the area. - Page 32 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.
