Put the disc harrow on the back of the tractor following the manufacturer's instructions for your model. Lower the blades to the ground and pull it across the ground. The disc harrow breaks up hard soil, so it's easier when you use the box blade. Make sure you lift the blade up when you turn corners. It makes turning the tractor safer. Go across the soil several times, so the soil breaks into small chunks.
Put the rototiller attachment on the tractor according to the manufacturer's instructions. Lower the rototiller to the soil and till over the area. The rototiller breaks the small chunks into smaller pieces. Go over the area several times.
Connect the disc hiller to the back of the power take off on the tractor according to the manufacturer's instructions. The hiller pushes the soil up into rows as you drive across the soil. Hillers make anywhere from one to eight rows depending on your model.
Attach a box blade to the tractor according to the manufacturer's instructions. Lower the box blade to the ground, so it cuts down into the soil. Go between the rows you created using the disc hiller. As the tractor goes across the ground, it cuts into the ground, and pulls in the soil. Once the box blade is full, lift the box blade, and dump the dirt onto the row.
Place railroad ties or trees you cut down on each side of the raised rows, so the dirt stays in place. This keeps the elevated rows in place.
