FAQs

Can you mulch with all lawn mowers?

No, you cannot. Some lawn mowers come with mulching, discharge or bagging features and others do not. If the mower in question does not come with a mulcher, check to see if you can buy one from the producer as an accessory. Push, riding and zero turn mowers can all have mulching abilities. Look for “2-in-1” or “3-in-1” in the description of a mower, and mulching is likely included.

Does mulching function make the lawn mower cost more money?

No, it does not. In fact, there are many budget lawn mowers that feature mulching, and some that even include 3-in-1 features. Premium lawn mowers often do work for mulching if they come with all of the bells and whistles, however.

If you have to purchase a mulching attachment from the manufacturer separately, it can add to the cost but is often inexpensive. Mulching accessories are most common in riding mowers.

What does mulching refer to when it comes to mowing the lawn?

Mulching refers to the process of returning the grass back to the lawn, so to speak. As you mow, bits and clumps of blades of grass fly up and bunch together. Mowers with mulching functions gently return the grass trimmings to the ground after you have cut them.

It is usually either in extremely fine trimmings, or in clumps. It is a way to nurture your yard and saves you from having to collect yard waste.

Is the mulching function any better or worse on an electric vs. gas powered mower?

No, there is no difference in mulching function between the two. The only difference in mulching function is based on a mower to mower basis. Sometimes, however, electric mowers are able to cut the grass into finer bits if it has certain technology such as INTELLICUT and other advances.

What do I do if I broke the mulching attachment on my mower?

If your mower is under warranty, and many of them are, contact the manufacturer. Otherwise, you can look into whether or not the manufacturer sells replacement parts or even more current, updated mulching attachments.

Many mowers come with removable mulching and discharge attachments, so if that is the case, fixing or replacing it is not difficult.
