GRASS HEIGHT AND CUTTING SUGGESTIONS
Do not attempt to cut grass when it is wet.
If the grass is tall, place the mower deck cut height lever in
the top or second notch. “Initially” overlap cutting swaths
instead of a full swath with each pass. Some applications
may require a second cutting.
Keep the underside of the mower deck clean.
Maintain sharp blades throughout the cutting season.
As a rule of thumb, never cut off more than one third of the
total grass blade length. Correct mowing height can reduce
weeds and disease by 50% to 80%.
The following grass cut heights are based on adequate
moisture conditions and normal thatch buildup in a healthy
lawn. Some locations and applications may require slightly
different cut heights. If in doubt, consult your local lawn
professional for assistance.
