Abstract

It is long known that reactions resulting from the penetration of coulters into the compacted soil generate more strain on the crop row, decrease the service life of its components, and represent an unwanted maintenance cost, often at mid-seeding. The objective of the study was to assess straining on a double disc coulter of a commercial planter using a dynamometric car, which measured the vertical and horizontal forces operating on the three double disc supports at different angles of attack. Forward speed ranged in three levels and working depth ranged in two levels. The tests were performed in the Stara experimental farming area in the city of Não-Me-Toque, RS, Brazil. It was possible to conclude that the range of angles of attack of offset double discs decreased the power requirements on the crop rows. It was also concluded that the working speed had a significant effect only on the vertical force component, due to the lager angular opening.
