Are Lawn mower levels accurate
My husband keeps adjusting the levels on lawn mower. In my opinion when he puts setting on 5 the lawn looks better, however lately he did it at 3 because everyone states that KBJ/TTfescus should be mowed at that height. I do not think our lawn mower levels are accurate. When you place levels on 3, the lawn looks extremely short and you see yellow at roots. When it is cut higher, grass is green. How accurate are levels?
