You have had several posts on the same subject all over the forum, no need, I've combined them all on this thread, please go back to the beginning of the thread and re read all of it for all the answers.
You asked the same questions back in 6-19 and the answer has not changed, neither a D600 or a D722, or many many other models will fit that tractor.
Like I said before only a D650, D750, D850, Or a D950 will be a direct replacement.
You also should not have D650 in you B7001, you have a D750, unless someone has replaced the D750, with a D650.
And FYI: There are 2 versions of the D850, and D950, and only one version will be a direct replacement for your D750.
