I cut with my rotary mower raised occasionally. The quality or cut is fair, but sometimes that's all I need. Last week I 'mowed' an area of warm season prairie grass I planted in June. The new grasses germinated well, but the first year they only grow to a few inches tall while they get established. The area was infested with foxtail and Canada thistle which were both about to go into seed stage. So I raised the mower to approximately 10" and cut the tops of the weeds to allow light to reach the grass seedlings. The results aren't great, but I've done this before and it works much better than doing nothing.
