I am told that Toro Proline 21" hand mowers with 5.5hp 2 cy Sizuki are no longer available (maybe a few still on the shelf). Also, I'm told that 21" LawnBoy commercial, 6.5hp Dura-Force engine, will be very limited in supply this season. What do you know? Is Toro Proline 21" hand mowers only going to have Kaw 4 cy engines? Is there any other choice? And, what about the LawnBoy? Are they being phased out too? The above info was given to me from a large mail-order supplier for commercial lawn equipment. I was told a flat "no" on the Toro, and "order very early" on the LawnBoy. The Toro web site is no different than last month.
