ABSTRACT:
A drill for seeds and/or solid fertilizer having a support frame and a plurality of planter row units extending transversally of the direction of travel which are separated in first, second and third groups. A central member supports the first group and is attached to the support frame in a transverse manner so that the units of the first group are in contact with the ground in an operational position. First and second outer members respectively support the second and third groups and are attached respectively to a first and second end of the central member so that the outer members can rest in a first operational position collinear with the central member with the units of the second and third groups in contact with the ground, in a second position parallel to and over the central member, and in a third position perpendicular to and over the central member.
