Yeah it does say that, which is misleading. If the 150BT is commercial then the 350BT is as well. They have the same engine, blower, and tubes as each other, just the 150BT has a cheaper harness. If the 150BT, a commercail blower, retails at $300, then why would the offer a landowner model for $20 more? Lowes does not carry commercial grade equipment and if you don't believe that then buy a mower from them, use it commercially, and let me know how it works out for you
