I probably should have elaborated more I need to know what the model for the whole machine is. I ran the numbers on the hoe and it came back as a 765. I searched the unit number and found a thread that listed what I believe is a different model but had the same unit number. The unit number came back as a build year of 1982.The standard backhoe for the 3400/3500 was the 10 foot model 730.
Blue now but It might have been repainted.Model CU411K= 3400 diesel. no pto, 6X4 trans.
Built 2F01B = June 1, 1972, Day shift.
3400 built from '65 to '75.
Is your tractor blue or yellow?
I ran the numbers I found on the data plate on the hoe. It was on the left side of the machine near the main pivot. It's a pretty big stick. Seems a little too big for the machine. I'll have to get the loader number tomorrow. I attached the only picture that shows most of the machine that I currently have. I can take more tomorrow.How did you determine you have a 765 backhoe? Also what is the loader # ? it should be on a plate on the inside of the loader arms, where the support plate is welded.
