Gas consumption of 27 kohler verses 34 kaw

[SNOWBIRD]

Can Toro tell me how much more gas the 34 HP kaw will use that the 27 HP (non efi) Kohler on the same 60" deck?

Snowbird -
Engine manufacturers don't provide us with this type of data, nor do we have this information, because too many variables exist related to duty cycles. Certainly the 34hp big block engine burns more fuel, but it also provides more muscle.

Thank you,
