Maintenance Schedule; Maintenance; Operation - Husqvarna 5521CHV Owner's Manual

• Avoid cutting your lawn when it is wet. Wet grass tends
to form clumps and interferes with the mulching action.
The best time to mow your lawn is the early afternoon.
At this time the grass has dried, yet the newly cut area
will not be exposed to direct sunlight.
• For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 10). If the lawn is over-
grown it will be necessary to raise the height of cut to
reduce pushing effort and to keep from overloading
the engine and leaving clumps of mulched grass. For
extremely heavy mulching, reduce your width of cut by
overlapping previously cut path and mow slowly.
• Certain types of grass and grass conditions may require
that an area be mulched a second time to completely
hide the clippings. When doing a second cut, mow
across (perpendicular) to the fi rst cut path.

3 - Replace blades more often when mowing in sandy soil.
4 - Charge 48 hours at end of season.
5 - And after each 5 hours of use.
• Change your cutting pattern from week to week. Mow
