Save the close trimming for the end.

Sometimes it is easier to divide a large irregularly shaped area into smaller sections, Fig. 12 center, to keep the mower working more steadily or to keep from reversing,turning or repeatingtoo often.

6 In a small area, where tight turns would cause lost nme in the center if the normal round and round methods were used,try the cutting method in Fig. 12 ieft. Make the second pass down the center of the area rather than down the opposite side from the first pass. This allows you to swing wide at the end of each pass and still cut all the grass with a minimum of reversing.
