Tractive efficiency can be increased in several ways. Research has shown that the shape of the ground contact area, or footprint, of a tractive device is important. A footprint that is long and narrow in the direction of travel compacts less of the total soils surface area than one that is short and wide, thereby reducing rolling losses. The fron portion of the device establishes a firm travel path for much of the rest of the device, resulting in improved traction. The length/width ratio of tractive devices may be increased by using tracks, tandem drive wheels, large-diameter tires, or radial ply tires. Cultural practices can affect tractive efficiency. A system of controlled traffic that establishes permanent traffic lanes for wheels is discussed. This system not only improves traction and flotation, but also reduces tillage requirements and improves water utilization. Low tractive efficiency can be avoided by the direct application of engine power to the soil through poer-driven tillers. Such tools are often capable of providing sufficient draft to propel the vehicle through a field while also tilling the soil. (Wassmann)
