Think of all the time, money and effort it would take to bag all those clippings. This allows you to reduce the amount of additional commercial fertilizer you need to apply. Recycling clippings back into the lawn requires less effort than disposing of them as waste. No one has to handle the clippings - not you, not your lawn care professional and not the waste management crew.
Any mower can recycle grass clippings.
You can also have a mulching blade installed. Mow when the grass is dry. Keep your mower blade sharp because dull mowers tear the grass blade, injuring the plant, and create a brownish cast to the turf. If the grass gets just a bit too high, simply mow over the clippings a second time to further shred and scatter them. If excessive growth occurs between mowings, raise the mower height, mow and then gradually lower it over a span of several mowings.
