hydraulics?
(OP)
what is the average working psi on a subaru power steering
pump and with remote resorvoir, would this pump operate a
2.25''x14 '' 25 ton at 10,000 psi cylinder. I realize the
volume will be slow , however, the load would only be the
bed of a lawn trailer with bed size of 30''x 60'' x16''.
The pump is to be fitted to a cub cadet lawn tractor so I
had to choose a very small pump to fit close space.

I think he's safe, but it might be a bit closer than you imply. (depends on the geometry of the ram - if it is flat in the trailer it could be bad, if it is direct lift on the front of the trailer it's fine, but the stroke is too short.)
Our p/s pump (not a Subaru) is rated for 1400 psi max pressure, 2.5 gpm max flow, at about 750 rpm (having to guess the step-up ratio on the FEAD).
That means his ram will develop a lift of only 3 tons or so, and at a very reasonable 5000 rpm would take about a second to fully stroke the cylinder.
