I'm trying to run a mower deck with a hydraulic motor. It spins @ 90 rpm and I need to provide 2200 rpm. I was planning on #60 chain @ 4:1 from motor to a jackshaft then single belt @ 6:1 to get the speed up. Will this work or do I need to re-think? Thanks in advance!

Might be cheaper, certainly easier, to get a surplus hydraulic motor with the desired RPM in the first place.
90 RPM? Are you sure about that? Most hydraulic motors turn QUITE a bit faster than that, usually in the 1000 RPM range. If it has a gear train on the output, can you remove the gearbox?

Sounds like a hydraulic steering servo motor. Can't remember the generic name offhand - something like orbital.

The motor is almost certainly an orbiting gerotor type motor. Common as dirt on mobile equipment. The low speed, high torque output is inherent in the design, which resembles that of a cycloidal reducer.
I built a large test stand and automation for building a few flavors of the motors 15-20 years ago.
