MOWING TIPS
Which Blade?
Grasses and lawn conditions vary greatly, so Harmony II models can
use various combinations of standard and accessory blades. Use this
blade application guide to help determine which blade(s) are best
suited for your lawn. For more information about blades, see page 60.
Always use an upper and lower blade on HRR, HRT, and HRZ models.
When to Mow
Most grasses should be mowed when they have grown ½ to 1 inch
above their recommended height. More frequent mowing is required
for mulching than for bagging. For best mulching results, you may
need to mow the lawn twice a week during the growing season.
Cutting Height
Consult a local nursery or lawn and garden center for cutting height
recommendations and advice about specific types of grasses and
growing conditions in your area.
Most grass has stems and leaves. If you cut off the leaves, you’ll scalp
the lawn. Let the grass recover between mowings. Your mower will
work better, and your lawn will look better.
If your grass gets too tall, cut it once at the highest cutting height
setting, then mow again in 2 or 3 days. Don’t take off more than one
third of total grass height in any one mowing, or brown patches may
develop. Cutting height adjustment is explained on page 11.
