Mahindra 2555 T&T

[MicroRacer]

Looking for some advice. I have a Mahindra 2555 HST that I use for a lot of different things but one of the main ones is maintaining a race track. I use a grader blade and box blade a lot for this. I would also like to add another remote valve at the same time as I put in the valves for the T&T. What I am asking is what do I need? I am not completely dumb about hydraulics but dont know which type of valve setup will work with my tractor or which type would work best for this type of application.
Thanks for any input.

So how many sets of rear remotes are you actually wanting?
