With any hydraulic system, the two main factors are flow and pressure. Flow translates into how fast the work can be done, and pressure translates into how much work can be done. On a tractor like your 400, the pump is what determines how much flow is avalible, and the relief valve controls max pressure, so changing out the pump would not be a good starting point. That brings us to hydraulic cylinders. A cylinder with a small diameter requires more pressure to lift the same amount of weight than a large diameter cylinder. So, you could go to a larger cylinder, but the drawback would be that it would take much longer to extend, since it takes more flow to operate.
