Hello guys, you all have it made up there in the states good for you guys with all the incentives. I have a Ferris IS3100ZP 61" with a 32 Hp Briggs big block, and im getting 1.4 gph. Oh yeah bought it brand new as a propane unit, however down here we use a 60% butane to 40% propane mix. Its been working fine! I have 60 some hours on it and like it. Gas down here is $6.00 a gallon propane is $2.00 so much cheaper. Good Luck!
