The region Alto Paranaíba features large areas of commercial carrot production. Obtaining roots of good commercial quality demands beyond the acquisition of quality seeds a training ground without physical impairments and the presence of cultural remains. However it has to be the input range of agricultural equipment for soil preparation in carrot cultivation is determined by trade issues, allowing inadequate soil preparation techniques. This study aimed to describe some of the effects of agricultural machinery for soil tillage in commercial production area of carrots, as the soil resistance to penetration (RP), soil water content (% U), geometric mean diameter (DMG) and mean weight diameter (DMP) and percentage of fines (FINOS %) five conditions before tillage "the" last post of disking "b", the disc plow "c" harrow "d" and rotoencanteiradora "and" where the action of a post mobilization equipment reflects in their action added to the history of previous demonstrations. This study also aims to develop a tool that allows better visualization of the effect of equipment for the RP parameter along the soil profile. The study was conducted in a demarcated area under pivot. The highest form found on the PR condition "a", ie, before turning the soil at levels up to 5800 kPa. The variability of moisture compared vertically statistical difference only for collection "and". The weighted average diameter did not influence the percentage of fine aggregates. The maximum mechanical strength of soil obtained without compromising productivity for the carrot was obtained after mobilization by harrow. The method of data interpolation by the inverse square of the distance is suitable for preparation of contour maps. Contour maps proved as easy to read tool and interpretation of RP throughout the soil profile.
