Engine size needed to run pump

sportnatic · Feb 3, 2011

I have an old Hustler Excel 400 mower and it has has a Sundstram pump model M91-2303 85-31-10055.I have tried finding the flow,gpm,rpms needed, etc. for this pump but have come up empty. What size motor would be needed to power the pump so it could be used again. There is no mower for this and all I want is to make it to pull a small cart around. Any info,websites with info ,or your thoughts would be appreciated.

Thanks
