BLUESAWS - The Holzfforma FL8500 Backpack Blower is a Redmax/Zenoah 8500 clone. We've been using is quite a bit as the summer comes to an end here in PA and MT . We have been impressed with the performance of this blower and the Farmertec OPE in general. Someone said about blowers to us as we got into this, Many guys go from Sthl to Redmax on the blowers. Nobody goes from Redmax back to Sthl. We can see why Farmertec used this well regarded model to be their first offering on blowers. It is a great unit.
