I have found the Harley Rake that mounts on the back of a tractor is easier to use and set grade with than a front mounted skid steeper type. That said, I have spent many more hours on a tractor than skid steer. 25M is fairly small for a machine of that size. If you have many trees, fences, or other obstructions it may not work well. You could try adding soil mix to your low areas, dragging it to blend, then slit seeding. Hard to say without seeing it.
