Has anyone ever modified their Permagreen to spray more per 1000 sq. ft.? I am looking to get at least 1 gallon per 1000 sq. ft. I realize I could slow down to 1 MPH, or run over the turf 4 times, but obviously I still want to stay productive and run at a decent speed and go over the turf once. TSC does sell a pump that is over 3gpm, but I would assume that I would have to change tips and mabye pressure caps.
