Have a cone wood splitter for skid steer that doesn't have enough torque. It works, but the cone gets stuck and it's a fight. What would have more power, motor wise? This thing spins super fast which I also don't need... I'd guess 500+ rpm where even 200 would be fine I think it's 20 cu in? 6800 in lb Skid steer is 22gpm, 3300 psi max
Might need something like a skid steer drive motor. High torque low speed. Maybe a gear reduction or chain drive of some sort.
Showing the engine rpms may help in the short term. Doubt is 20 cu in, more likely to be cc, 20 ci= 327.74cc which is a big motor. This outfit has all the info you need to workout speeds,flow and pressure on their website You searched for Hydraulic specs - Berendsen berendsen.com.au
Crosses to a Charlynnn 2000. It's 18.6 cu in. 560 ft lbs torque... allegedly. Biggest is 30 cu in, 620 ft/lb
