Abstract

Two essentially parallel rows of spring pins (4') are used to work the soil, each row of pins being mounted on the end of a rotating arm (2'', 3''). The arms are moved in synchronism with each other in a direction at right angles to the row of pins, between a first released position and a second position where the two rows of pins are swung in next to each other to meet in an essentially vertical central plane of the machine.
