Saw the picture of it on the wrap from the L&L magazine today... There's nothing about it on their site other than the little 1 gallon model that hangs on the side of the spreader. This one appeared to be ground driven? looked like there was a wheel that maybe pumped the fluid? The picture was was kinda a drawing I guess, so a little hard to tell. Anyone have any sort of additional info on the unit? could it be adapted to be used in a HPS spreader?
