As a result, the design of an implement is obtained that works at a proposed speed of 7 km h-1 and that collects the plastic, cutting the soil of the agricultural bed 10 cm on each side, in order to ensure that it cuts the plastic of the mulch. It has a width of 1.3 m and a load capacity of 646 kg of plastic that can be kept in the collection shaft before having to deposit it in a warehouse.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN En este trabajo el objetivo consiste en diseñar un implemento para recolectar el plástico utilizado en acolchados de fresa, cortándolo a ras de suelo por cada lado de la cama agrícola sobre la cual se siembra la fresa, y lo enrolla en un eje que gira de manera proporcional al avance del tractor, accionado por un sistema de transmisión de potencia de cadena que relaciona el movimiento de los neumáticos del implemento y el enrollado de película plástica. Como resultado se obtiene el diseño de un implemento que trabaja a una velocidad propuesta de 7 km·h-1 y que recolecta el plástico, cortando el suelo de la cama agrícola 10 cm por cada costado, para poder asegurar que corta el plástico del acolchado, tiene un ancho de 1.3 m y una capacidad de carga de 646 kg de plástico que pueden ser mantenidos en el eje de recolección antes de tener que depositarlo en un almacén.]]></p></abstract>
