Tire Options and Consequences for Four-Wheel Drive Tractors

Some general principles have been developed that will assist operators in the selection of tire and wheel equipment. Traction performance is enhanced by tire configurations which give long, narrow footprints in the direction of travel. This may be accomplished in several ways: tracks, tandem drive wheels, increasing diameter, or radial ply construction. A system of traffic control that can save tillage energy is discussed, and the effect of total load on soil compaction is shown.
