The study is to develop technical knowledge of the application of some planting methods, introduce new planting arrangements and eliminate the traditional methods. The interactions of planting blades and soil were modeled using Abaqus 6.12 software and the plate sinkage test. In this simulation, soil is considered as an elasto-plastic body with two criteria: Mohr-Columbus, Drucker-Prager where plowing effect considered as compressive force. The linear work performance monitoring system improves the efficiency of planting operations by providing online feedback from the working conditions of seed driller parts. To monitor the performance of the machine, some cameras on the distributors and a camera instead of a marker were used. This experiment was performed in the farm of Bu Ali Sina University of Hamadan with sandy-loamy tissue at a moisture level of 15%. Planter furrowers were in six types: b1: v-shaped, b2: u-shaped, b3: inverted t, b4: two-plate v-shaped, b5: cross-shaped, and b6: tulip-shaped. Soil compaction is known as a complex and multidimensional problem involving the interaction of soil and machine. In the process of planting by seed driller, the issues such as failures of seed distribution systems, emptying of the seed container, etc., can occur widely. The modeling results with Abacus software showed that the Drucker-Prager behavioral model with a correlation coefficient of 93% had a higher agreement than the Mohr-Columb model with a coefficient of 63%. The amount of stress and displacement in the layers close to the load surface was high. It decreased from upper to lower layers.
