Sears offers the Craftsman 21" Gold Series Self-Propelled Mower for $242.99. Plus, SYWR members earn about $30 in SYWR Points. (Not a member? it's free to join.) With free shipping and assuming you'll use the credit, that's a savings of $147 and the lowest price we could find. It features a front drive, single speed propelled drive system, and dust-blocker grass bag.
