To get a good result
• Always use a sharp blade. A blunt blade gives an
irregular result and the cut surface of the grass
becomes yellow. A sharp blade also uses less
energy than a blunt blade.
• Do not cut more than ⅓ of the length of the grass.
Cut first with the cutting height set high. Examine the
result and lower the cutting height to an applicable
level. If the grass is very long, drive slowly and cut 2
times if necessary.
• Cut in different directions each time to prevent
stripes in the lawn.
To cut grass without a grass catcher or
mulch plug attached (LC 551iV)
1. Lift up the rear cover and remove the grass catcher.
2. If a mulch plug and a mulch blade are attached,
remove them.
3. Close the rear cover before you operate the product.
When you operate the product, the cut grass discharges
below the rear cover.
