the hydraulic motors generally arent marked with anything other than a model number,and MAYBE the manufacturer in the casting somewhere.You have to take the model number and go on the 'net and search for the data page from the spec sheets and go from there..you can measure the width of the gears and diameter if its a pump,but that would require disassembly-kinda counterproductive tho.Best approach on this one you have pictured is to start with the manufacturers data sheet on the machine,or service manual might spec it out. From what Ive learned in building machines,build in as much weight as you can,it adds traction to the wheels for pushing and pulling..this machine was never designed for cross country duty gathering trees and wood but it'l probably work-you already have the tires for it..but for my money,take the vib plow off and sell it-recoup some of that money for materials to mod the machine for your new use.The foundation is there. FWIW
