ISO b7200 front loader with hydraulics as i am poor it needs to be reasonably priced
if you are up for project and want it cheap then their is a facebook group all about salvage for B's and L's kubota. It's called Kubota B BX and L tractor salvage.
in the group one guy selling a B1640a loader for $850. Located PNW I believe. now being salvage if has more than a few warts buts its inexpensive.
Needs bucket, some hoses, lower frame and valve. but its a start and others in this club will have these pieces about i'm sure.
Good luck!
