That's about it. Yes, it does have non-beneficial aspects to it, but in most cases, the small adverse effect it has really doesn't make that much difference...especially if the lawn has a full care program that includes aeration. We do it, and will continue to do it. Like was mentioned earlier, lawns with conditions like mole damage, and others, are prime candidates, but so are some of the lawns that just have a tendency to get lumpy (aeration really helps this, as well). When lawns are really soft, like first thing in the spring, much of this can be relieved by a simple rolling. It is just scratching the surface, anyway. It is not like an asphalt roller or vibrator compactor is going over it. As a matter of fact, per square inch, rollers don't weigh anymore than a person walking on the lawn. We, however, have a pretty decent roller that stands about 3 ft tall (most that are available are not that heavy) - you can't go by the width of the roller, but the actual height. Yes, it DOES smooth it out for the rest of the season (for the most part). Anyway, we do rolling relatively inexpensively. we charge anywhere from 50 to 75 for a standard 1/2 acre lot. It is just too easy. the main thing is, is having a transport and securing method. Most people don't have this, so the roller has to be emptied to transport. If this is the case, the price would have to go WAY up.
