What engine size do I need?

Most picks here run 144cc to 201cc. Reviewers note 144cc engines suit small, well-maintained lawns, while 201cc models from SENIX and YARDMAX handle taller, thicker grass and mulching with less bogging. Larger engines add weight, which Home Depot reviewers cite as a downside on the 22- and 24-inch YARDMAX decks.
