NOTE: When cutting long lawn or dense lawn, if the unevenness in the length of lawn or poor finish is found after mowing, or decrease of the motor speed is found during mowing, decrease the mowing speed lower than recommended in this manual, or raise the mowing height.

The center lines of the front wheels are guidelines to mowing width. Using the center lines as guidelines, mow in strips. Overlap by one half to one third the previous strip to mow the lawn evenly.

Change the mowing direction each time to prevent the grass grain pattern from forming in just one direction.

Periodically check the grass basket for mowed grass. Empty the grass before it becomes full. Before every peri-odical check, be sure to stop and turn off the machine.

NOTICE: Using the mower with the grass basket full prevents smooth blade rotation and places an extra load on the motor, which may cause breakdown.

Mowing long lawn

Do not try to cut long lawn all at once. Instead, mow the lawn in steps. Leave a day or two between mowings until the lawn becomes evenly short.

NOTE: Mowing long lawn to short length all at once may cause the lawn to die. The cut lawn may also block up inside of the mower body.
NOTE: If the unevenness in the length of lawn or poor finish is found after mowing, or decrease of the motor speed is found during mowing, decrease the mowing speed, or raise the mowing height.

Emptying the grass basket

WARNING: To reduce a risk of accident, reg-ularly check the grass basket for any damage or weakened strength. Replace the grass basket if necessary.
