    So i have been throwing snow with a 2001 John Deere this year with a FFA 72" snow thrower and it has mainly worked well... JD capacity is 15 GPM and the thrower is rated between 14 and 22 GPM.. Tomorrow i am getting a Cat 2007 248b with a minimum GPM of 22 and with High Output of 33 GPm. My question is will there be a noticeable difference with the higher gpm running the snow thower...

    Yes, there should be a remarkable difference, the older JDs were not known for their flow rates or PSI. One word of caution, if the blower only has 2 hose hookups (which I presume it will with those flow rates) do not put it into high flow. The third hose is a case drain, and is needed for high flow operation from my understanding.

    The hi flow will tear the hydraulic motor on the blower apart. On a Cat the hi flow is activated in the wire connection, 2 pins are jumpered together. So you can use both standard flow and hi flow attachments on a hi flow machine.

    I suspect he may have already done that - his original message was a day before I replied. Good to know about the Cat, my Bobcat does that too, but you can override it.

    Hi Flow

    The Cat 248b has a switch that controlls Auxillary hydraulics that either operates in High flow or Standard flow. We are getting a harness from FFC to attach to the electical connection on the Cat. So for this harness/ Thrower it shouldnt allow a high flow from the Cat.
    Hopefully it work out well....
    Thanks for posts......

    Right you have the switch but it needs the 2 pins jumpered to complete the circuit to actually operate in hi flow
