While you can run a loader off of the on-board hydraulics, the better method is to mount a pump to the front of the crankshaft. The on-board pump puts out less than 5 gpm which makes the loader operate too slowly. A 15 gpm pump is a better target. And beware, a trip bucket is somewhat limited in its usefullness, but is handy if there is nothing else. What's more important is the general condition of the rest of the tractor. The six-speed gearbox produced speeds from about 1.5 to 15 mph. Oliver industrial tractors that were factory fitted with a power operated loader and/or backhoe used a front mounted pump driven by a shaft that threaded into the front of the crankshaft with four bushed bolts, out through the bottom of the radiator grill and then coupled to the pump. A similar setup would not be that hard to fabricate. The reservoir was mounted directly in front of the grill and over the pump but that put even more weight on the already over burdened front end. As others have written, the Super 55 did offer power steering but only in the very latest years ('56-'57) and it is very rare indeed. Moreover, the design used a torque amplifier that multipled the turning force from the steering wheel directly to the steering box input worm shaft. While a clean and efficient system, it put too much strain on the steering box sector teeth especially when turned to lock, often breaking the teeth. Oliver responded with stronger sectors, but then abandonded the system in favor of a piston driven assist sometime in 1962. So, if you are looking for a sturdy Oliver in the class of a Super 55, choose instead an Oliver 550. They are basically the same machine on the same chassis but with slightly larger engine displacement and more of the bugs worked out. If you don't need or care about TPH or PTO, opt for an industrial model as the front axles were beefier and it is more likely to come with power steering standard. I have two such machines, one fitted with a loader and hoe (with a custom hydro oil tank moved to the rear) and the other a rare industrial with TPH and PTO. Both have PS of the different generations. If you are in the central NJ area, you are welcome to have a look.
