Abstract: Tractor implements can work the ground in a proper and efficient manner to ensure the ground is ready for planting. The tractor implements can be arranged in various, specific manners, in series behind a tractor, depending on field conditions. For example, the tractor may pull a single disc positioned ahead of each ripper disposed on a ripper implement. Behind the ripper, a roller implement may be disposed for lifting, rolling and breaking up the soil. An optional disc may be provided forward of each roller blade assembly. Behind the roller implement, one or more finishers, such as a disc, a multi-disc, a chopper, a basket, a double basket, a knife, a deflector, or the like, may be used to finish the worked soil. Soil prepared by such implements have been shown to significantly increase crop yield.
