1. When using a lawnmower do a general scan within the area you intend to work. This is just an extra precaution to make sure they are no bigger objects that will contact the mower blade. Mower blades can cause a spark. Even if your grass is green a spark can fly into a dry area nearby.

2. If you are unsure of what is beneath the grass, try raising your mower deck a bit higher for the first pass then lowering it to the desired height on the second pass.

3. For those who get easily fatigued by carrying around a weed eater. A walk behind string trimmer mower is a great alternative and, in many cases, will give you equal results.

Other Tips

  • Use a small tarp, tailgate, or pavement as a temporary fuel station to avoid gas spills. Gas and dry vegetation are dangerous combination especially at high temperatures.
  • Always have a fire extinguisher, shovel, or water readily available in the case of an emergency.
  • It is always a good idea to mow during the coolest parts of the day. This not only reduces the chances of a fire but also reduces fatigue.
  • Park vehicles away from vegetation if you are transporting equipment to a job site. Catalytic converters can ignite dry vegetation. Likewise, keep recently used equipment off vegetation. Certain metal parts on a small engine can get overheated and cause fire once it contacts vegetation.

If you must mow during extremely dangerous conditions, it is always best to keep up to date with guidelines pertaining to the area you live in.
