Can I mow over the millions of acorns on my property? I am afraid they will break my mower! There are SO MANY this year!

Acorns are either too heavy and won’t be sucked up, and/or the mower setting/blade height won’t put the blade any where near the acorns.

You can gather them if they present a condition which either tracks the cracked broken shells in the house, or creates a concern for an unwanted 'roller skating' condition.

One nice "green" idea is to gather them up and put them off to the side, so the wild life can still have the natural food source.
