Does anyone out there know if the Bobcat concrete pump will work on any other brand machines (Specifically the JD320)? I know when I was shopping for skid steers, the Bobcat sales guy told me that some of their attachments were proprietary but I didn't ask about the pump. Since then I have had to rent a pump truck 4 times in a very short period of time and see the need to rent one many more times in the near future. This may be a purchase that is definately worth my while...as long as it will work on a John Deere skid. Thanks!
