texbaylea and smat:
The Kubota hydraulic remotes are stackable, that is, after the first remote, all you do is add the valve bodies and actuator levers onto the first valve body. You can go with three on the GrandL series (lever controlled) and if you want to, you could split the three three more times electrically for a total of 6 remotes.
$650.00 for the remote is about right. It's hard to get into the area where they mount so it takes time and disassembly. of other non-related components. I'd add ALL the remotes you think you need at one time as every time you add another, you have to do the non-component dissassembly to get to the area where the valve body mounts.
