I can't say becuase I haven't ran both but I have the 37 DFI and it has plenty power but its a gas hog... But in all honesty I'm comparing that to my Ferris 2000 with a 25 kawasaki.... So it's not a fair comparison with the 3100 having bigger pumps for the 37 kawasaki to run and bigger tires to pull.... And the 3100 seems to have a higher blade tip speed... I know the pulleys on the deck are smaller than my 2000s deck pulleys....

I see the compression ratio's are very close too. The 32 is 8.2:1 and the 37 is 8.4:1. The 32 should perform very similarly, just on a smaller scale due to less cc's.
