What height do I cut Low Mow sod once established? How long after it is laid do I start cutting it?

Our HD 2000 Kentucky Bluegrass low mow is trained to a height of 3/4". It should be mowed at least 2-3 times a week to maintain that level. You can start mowing the grass after 5-8 days after installation. FYI, A reel type mower should be used and not a rotary type mower to maintain that level of height.
