I have a John Deere Skid Steer model 4475, the unit runs really well and gets the job done. I now have the need to use a grapple bucket with the machine. I need to find an auxiliary hydraulic setup for the machine in order to use the additional cylinder. Does anyone know of a source for the kit? Also, I understand this machine was manufactured by New Holland, which unit does this cross-reference to? Thanks in advance.
