Do you have manuals? The OM (Operator's Manual) would help, and the WSM (WorkShop Manual) will likely be critical. As well, manuals for the loader and BH will be invaluable.
KubotaBooks is a great resource for manuals (and is free); they may have your FEL and/or BH (they don't list a B3200). I'm pretty sure
Messick's will have them, at a little lower price than Kubota dealers.
I'm only somewhat knowledgeable about hydraulics so I'll offer a couple of suggestions that may help you until the gurus chime in with the straight skinny.
Have you checked the fluid level of your FEL? It sounds like your tank isn't full enough to fully extend the pistons.
BHs have a separate source of fluid from FELs; in some cases, a separate reservoir and in others they share the transmission fluid. Your B3200 OM might tell you; your BH OM certainly would. (And many of the gurus here will, as well.
)
Good luck with your new toy, and keep us updated!
