Bobcat 730

[Clm1953]

I need advice help or advice for removing a Wisconsin Vh4d from my old bobcat, I have a repair manual and have a good mechanical background, I habve removed alll items to make ready for removal but it won't break loose, it picks up some but will not pull out the back, it suppose to have a slip coupling attached by a spline shaft, what's the trick to break it loose, thanks anybody.
