Just as you can troubleshoot problems with the lawn mower itself you can also troubleshoot actual mowing problems. That is, you can observe the results of cutting the grass with your lawn mower, identify problems, and figure out ways to avoid them in the future.

Here’s what I’m talking about. After mowing your lawn have you noticed such problems as streaking (thin strips of uncut grass left behind the mower), stepped cutting (sharp ridges left in the surface of the lawn after mowing), uneven cutting (wavy troughs in the surface of the lawn after mowing), scalping (deck of the lawn mower strikes the ground), or stingers (patches of uncut grass left behind the mower)?

All of these problems are caused by the lawn mower. The problems can result from an improper setting or adjustment of the mower, a dull blade, engine speed, clogged deck, damaged lawn mower part, and more.

Here are causes for certain problems and what you can do to prevent them from happening again.
