Hey real, this might help you and it might not. The hustler I have has the 850 on it and the ferris I used to run had the 32 bb. Obviously this is apples to oranges, but the 32 felt like it had considerably more power than the 850. Take note, I'm sure the super z's hydraulic system is larger than the 3100 that I ran so that sucks more power, but the 3100 was 72" compared to 66". The 32 is a hoss, so I'm sure the 36 is incredible. As far as fuel goes, in normal cutting my 850 is around 1.5 gal/hr. If I remember correctly, the 32 BB was sitting around 2 gal/hr so the 36 is in that neighborhood I'm sure.
