Abstract
Un accesorio de enganche por tres puntos, utilizado para fijar un apero de labranza a la parte delantera de un tractor propulsor, el accesorio de enganche incluye un bastidor sobre el que van montados dos conectores inferiores, prolongados hacia adelante, para ajuste lateral. U(na parte intermedia de cada uno de los conectores inferiores puede hacer contacto con un bloque de fricción situado en el bastidor del enganche. Los extremos delanteros de cada uno de los conectores inferiores llevan una rótula esférica abierta, que se dispone alrededor de un pasador de enganche del apero, el cual queda fijo mediante un pasador de sujección . Cuando los extremos posteriores de los conectores inferiores se ajustan uno hacia otro. La porción intermedia de cada uno de ellos se desplaza hacia su correspondiente bloque de fricción, con lo cual se estabiliza el apero y se controla su desplazamiento lateral. El bastidor del accesorio de enganche se puede acoplar fácilmente al tractor y separar del mismo
