He is probably talking about factory remotes.
If your tractor is open center hyds, you can add a single of a bank of valves for less than the factory remotes.
I am not sure of the tractor, but here is what one of the TBN members did.
I would recommend a set of three remotes with float on two of them.
The valve monoblock should have PB to feed the 2pt.
You would interrupt the PB line going to the 2pt and insert the three spool remote.
The PB from the new valve would go to the 3pt.
The Out hose would go to a return ling to tank.
The Pb hose from the hyd block would go to the IN port on the remote.
You can get a three spool stacked valve from Surplus like this.
