Get a group II Pronovost P-860 TRC with solid auger and Hardox drum and with drift cutters that will be 86 3/4" and is probably the best blower built.
Look at Normand and Agri-Metal also, they make good blowers too.
I am not sure about Schulte, they are rare around here but look fine, but not like the other three I mentioned.
Lucknow, Meteor, Walco, Smyth, Woodmax, Allied, McKee, and all the box store blowers are toys compared to a commercial one from Quebec.
