Mulching blades feature more curves and an increased cutting edge. The curved surface and increased cutting edge allows the blade to cut the grass and bring it into the deck where it is cut several more times before falling back onto the lawn in much smaller pieces. The curved design of a mulching blade does not provide the same type of lift and discharge power as standard blades. Mulching blades are an excellent choice for use on lawns that receive a mowing every three to four days.
Using mulching blades on overgrown grass can result in clogging under the deck and piles of grass on the cut lawn. In summer this is also a good way of helping the lawn conserve moisture. Grass clippings do not cause thatch but may cause problems if you already have a heavy thatch layer. See Checking for Lawn Thatch. Starting with the blades of mulching mowers, which are also called mulching blades, have a curved design with a larger cutting edge.
Because of this, the grass is cut multiple times, so only small pieces of grass fall on the ground. But the best thing about mulching blades is that they support a total of 3 functions which include bag, discharge, and mulch the grass clippings, which you can guess by the name. On the other hand, if you are going with a regular mower for your lawn, then its blade is only going to support discharge or bag modes for the grass clippings. You should also consider the deck design offered by any given lawn mower before buying one.
Talking about the differences between mulching mower vs regular mower, you will find that mulching mowers have a circulating deck design. This simply means that the grass clippings keep circulating around the blade in a way that they get cut into very small pieces. And in comparison to regular mowers, they have a deep and dome-shaped deck design for proper mulching of the grass clippings.
Some mulching mower models can also come with a baffle for directing airflow and the grass clippings. This can be useful for switching to the discharge mode of your mulching mower, especially when your mulching mower has an adjustable baffle.
Be sure to do some research for your particular mower manufacturer, because not all blades are universal. It always helps to keep mower blades sharp, but it is essential with mulching blades. Experts say the rule of thumb is to sharpen blades at least yearly or every 25 hours of use. Environmentalists and lawn experts all say: mulch your grass if you can. The number one reason to grasscycle is that it returns nutrients back into your lawn.
It helps reduce the need for chemical fertilizers. It can help cut back on the weeds in your lawn. No bagging helps reduce plastic volumes in landfills and all the associated microplastic issues. If your lawn is too wet, the cuttings may bunch up and end up in piles on your lawn, instead of being spread out.
Bunched, long clippings left on your lawn can smother it. Get those diseased clippings out of there by bagging. Then, tackle the diseased areas. Expert opinion is divided about mulching fall leaves. Some say that the volume of fall leaves is just too much for mulching lawn mowers to do a good job. The result is bunches of ripped up leaves on your lawn in piles, which take a lot of time to decompose and might suffocate your lawn. Other experts say that mulching fall leaves makes for a great nutrient add to your lawn.
The answer may depend on the type and volume of leaves — get the opinion of your local agriculture extension agent.
