Grass Cutting Tips:

1. Don't let your grass grow really tall, then cut it all off in one mowing.
2. Never mow more than 1/3 of the leaf blade at a time.
3. Mowing once a week should be sufficient. But if you've had a lot of rain and the grass has grown rapidly between mowings, you may have to mow more than once a week to honor the 1/3 rule.

More Mowing Tips:

1. Adjust the mower's height using the knob/notches near the wheels.
2. Don't mow when the grass is wet. It will clog up the mower and leave clumps on your lawn that could kill it.
3. Alternate mowing directions. Go up and down one time. Go back and forth the next. This will lessen the compaction stress on your grass.
4. Don't mow up and down hills. Mow across them.
