Abstract: A method for the vertical calibration of an agricultural machine wear tool is provided. The method includes: placing the wear tool in contact with a reference area; measuring the value of a position variable linked to the positioning of the wear tool when it is in contact with the reference area; determining the theoretical vertical positioning component of the wear tool according to the value measured, based on a reference curve; and determining a matching curve between a vertical positioning component of the wear tool and the position variable, by shifting the reference curve by a value equal to the theoretical vertical component.

Abstract: A method for producing marking strips using at least two seeders moving simultaneously in a field in which one seeder is a head seeder and at least one other seeder follows the head seeder being laterally offset, each seeder includes a control unit and plural rows that can respectively be activated for sowing or deactivated to produce tracks without seeds which will be used as a circulation lane for a treating apparatus in post-treatment operations. Each control unit includes a software program defining, with regard to fixed working parameters, an automatic operating program for activating or deactivating at least one of the rows of one of the seeders.
