HELP with Hydraulics on a Ford 3055

[athanasiosmavrides]

Hello enerybody, I am new to the forum and I have the following problem.
I bought an old Ford 3055 tractor (probably the 3055) and the Plate underneath the seat driver looks like that. (pic 1)
The plate underneath it looks like that (pic 2). I want to add external hydraulics in order to control a single way acting machinery as shown inthe schematic pepresentation (word file). So my question is the following:
Which adapter plate should I use for my Ford Tractor? HV4901-4902-5902 or something else? What is the difference between them?
Will any of these work with my tractor? How should I connect them?
Thank You in advance for your responses!!!
PS
Can I get pressure to work from the bolt on top of the original plate that is currently fixed as shown in pic3 View attachment 382848View attachment 382848( I will use return somewhere in the differential).

i'm pretty sure the 3055 was produced 70-74 so would be in the same time period as other 3000 series machines.

the hv5902 would seem to be the correct adapter plate to use with that machine. I'd double check that with rickb but the parts lookup I'm looking at seems to indicate only that adapter plate.
