I think cool season grasses should be between 1 ¾” and 2 ¼” in the northeast so you are at about the perfect height. I am, however, against increasing the height of the grass during the heat of the summer then mowing it shorter at the end of summer. Grass does not like to be stressed by mowing and when you have to lower the height, especially during late summer when it is still recovering from the heat of the season, you stress it even more. You are better off choosing a height and, more importantly, mowing often enough so you never cut off more than 1/3 of the length of the grass at any one time. That might mean mowing two, maybe three times a week during the spring and fall but only once a week during the hotter days of summer when it grows slower. An don’t forget that with good mowing techniques you can make your fields look great!!
