Knowing when to mow your lawn, how to keep the lines even and straight and how to care for your lawn mower is all part of doing the job correctly. Running your lawn mower to get the best from your lawn takes skill and practice.
Avoid mowing your lawn in the afternoon during the hottest part of the day, because this can cause unnecessary stress on your grass. Also do not mow your lawn after a heavy rain or around dawn because moist grass when cut can catch disease much easier. It is best to mow your lawn in the evening. The frequency at which you should mow your lawn depends on the type of grass, but most grasses need to be mowed about once a week. You should never cut off more than one-third of the grass blades' height at any one time.
Keep your lawn mower on course by making sure the wheels are at least 2 inches inside the last line you cut. Mow in long, straight lines across your lawn, alternating your direction so you are mowing in lines that are perpendicular to the lines you created during the last time you mowed.
Understand the contour of your land that you're mowing. Know your land. You should always run your lawn mower across hills to keep lines straight and to keep your footing.
Empty your lawn mower frequently so grass clumps don't collect and your mower will run at its optimum performance level.
Wash your lawn mower with a hose after each use. Add oil to working parts to keep your mower from rusting.
