I have several bobcats, 753, 763 & 773. Will the same backhoe # 609 brackets (that came off a 753) work for all of those models? Will it work on a # 853 or 863? The reason I ask is because I may sell a machine with this attachment, or may keep it for a possible future business opportunity. I'm pretty sure that the answer is yes, but a solid answer based on experience would be helpful.
