DB 990, 3 remotes

[Smiles79]

I've got a 1970 David Brown 990 Selectamatic. It's got a loader that runs off two valves mounted to the right of the seat (the camels hump it's called I think?) One valve handles the lift and the other is plumbed to QDs behind the seat and the loader tilt is plumbed to that.

I would like to be able to have one set of remotes while maintaining all functionality of the loader. Can I get a third of these remote valves and stack it on top of the two that are already there? Do these remote valves have power beyond that I can send to a third valve for remotes? I also have read a bit about a power beyond manifold. Do I get one of those and get rid of the two remote valves I have; plumbing the power beyond manifold to a loader valve then the power beyond from the loader valve to a dedicated remote valves? Or lastly, can I get one of those power beyond manifolds, stack the two remote valves onto it, and send the power beyond from the manifold to a dedicated remote valve?

Hopefully that all made sense. Thanks in advance!

The way a power beyond usually works is it stacks on beside the regular valves oil flows through it to a separate vavle stack like to run your loader circuits and you still would have the regular remotes in the rear. Another way you could do it if there is not a power beyond plate available for that tractor is to ad a valve stack to run your loader then either tap into a pressure line to feed it or tie a remote valve open and feed it that way. May get a bit of heat from the oil with the later.

When you say "it stacks in beside the regular valves" are you talking in general or for this tractor specifically? I'm familiar with the general idea of power beyond, but I just am trying to figure out to make this specific setup work on this tractor.

That's in general, but it appears that there is a power beyond manifold for the DB990.

The power beyond will let you add a joystick valve for your loader and free up the two rear remotes for whatever you want.

Yeah I've seen those, any idea if that can just stack on top of the two remote valves I already have mounted to the camels hump?
