Mulching leaves into the lawn with the 21 inch self-propelled Ego lawn mower

Has anyone used the 21 inch self-propelled cordless Ego lawn mower to mulch leaves into the grass rather than remove them, for a whole autumn season? If so, how did it perform? I read a study by Michigan State University recommending that autumn leaves be mulched into the lawn rather than removed with a rake or blower in order to fertilize the grass and save time. According to the study, as much as 6 inches of leaves can be mulched at a time. However, it recommends mulching until the leaves pieces are the size of a dime. Then they can decompose quickly and fertilize your lawn. Has anyone tried this with the Ego mower? Does it mulch the leaves into small enough pieces? If so, does it do so on one pass over the leaves, or do you need 2 or 3 or more passes to do so? If it doesn't break the leaves down small enough with the blade that comes with the mower, does Ego sell a different kind of blade that would help with this kind of leaf mulching? Or is there a blade not made by Ego that I could put on the Ego to mulch leaves into the grass?

Interesting study! From our perspective, the key factors to be considered are the amount of leaves being mulched and how finely the machine mulches leaves. As mentioned in the article, it is quite important to not smother grass. Otherwise, mulch will mat down, eventually killing or thinning the lawn. Another aspect to evaluate is the condition of the leaves; if the leaves are wet/damp while mulching, there is a greater chance of clumping and for poor mulch performance.
Ultimately, the user will need to use their own discretion. If they notice an abundance of thick coverage after mulching, they should either spread it around to thin it out or move some material to a flower bed/ garden area.
