Hello, I'm running a 773G with auxiliary hydraulics that puts out 16.7 GPM. I'm looking at a tiller that needs 18 GPM to operate according to it's spec sheet. Would anyone know - if I was to get this tiller, would I be able to run it with my hydraulic flow rate? I'm thinking I might be able to, but it wouldn't be able to operate at it's peak performance. It would only be used for tilling my garden. Thank you....
