for me they mostly trim and mow ditches and steep hills and some back yard s. was a time when they were my primary mowers but not so much now. during leaf season they are invaluable . I use snapper hi vac and ariens to bag and mulch leaves. I have a snapper hi vac rider for big yards but the 21,s see plenty of action in leaf duty. for me they serve a valuable service still and I ALWAYS have several on the trailer everyday. only thing I would change is have more variety in what we get to choose from now. only a few comm 21 still made . most companys have abandoned this market
I'd try a Toro Commercial 21 if it had a side-discharge chute out of the right side of the deck. The tube out of the back to the left is inferior.
Until then, the Toro SR21 is decent enough...just not Commercially durable.
