Recently I added rear remotes using the Kubota kits and the PB of that Kubota valve stack is what feeds the Backhoe itself. I’ve been pretty OCD when it comes to securing the 3-point hitch lever in the down position when hooking up the backhoe for use. In this snip from the BH77 manual, it’s also advising caution about downstream remote valves, but I would think the BH itself would be downstream of the rear remotes (at least from Kubota, anyway). Is that how others would read this? There’s no question my BH gets flow into it from my rear remotes, and the outlet flow of the BH then heads back to the tractor’s hydraulic block at that PB port. Opinions welcomed.

As the manual states, the backhoe will get shock loads from valves installed after it. The backhoe should always be second to last, before the three point. The three point is slow enough to not cause issues to the backhoe. If you were to install a front third function say loader>bh>3rd>3point you would have issues.
If instead it was setup loader>3rd>bh>three point you would be fine. Your rear remote would all depend on where it is in the lineup. If your certain it is before, then I don't see an issue. Trust me you will know if you have the wrong setup, because the backhoe will twitch when you use a valve farther in the PB lineup.
Just curious as what implement you would be using with the rear remotes, whilst the backhoe is on the machine. You could always close the pb loop from the backhoe and not take it off.

Thanks for the reply. No plan to use any rear remotes when the BH is on, just concerned if one of the three rear remotes valve levers got inadvertently moved while the BH happened to be on. I guess it’s to do with the BH’s ‘outlet’ line serving as both a PB and ‘return-to-Tank’ line? In any event, sounds like there won’t be any issue for example, if my arse should happen to bump a rear remote lever when bouncing over rocks, etc.
