Looking good. Yeah the cylinders might be a little big but if they work, use them! They were cheap so that accounts for something. The cylinders on mine are too big too but they were only $60 each! The johnson loader brochure shows that it ONLY helt 4 qts of fluid... based on the advice I've had in my own thread and from other builders, a one gallon resiviour should be enough for light duty work. I'm sure you don't plan on moving tons upon tons of rock with this thing.
Hey twostep, you have any pictuters of your tractor/loader?
