Something I found out about commercial rated versus residential types.

A few years back I bought a Scag commercial mower. The difference is
the blade tip speed.
Residential type mowers are restricted by federal regulations to some
maximum tip speed at full throttle.

Commercial types are not, and the tip speed of the blade is typically
much higher. Makes for better cuts and smaller mulch.

Just curious where you heard this.

I checked today with with my lawn mower repair shop, a place with some
old grease monkeys who've been around awhile. They said it's not true.
Said it was an internet rumor.
