• at least one drive configured to drive at least a part of the guide rollers,
• at least one pair of endless conveyor belts guided along the guide rollers, the guide rollers and the at least one pair of endless conveyor belts being configured to grip the fiber plants therebetween and transport the fiber plants in a gripped state to the self-propelling vehicle,
• the guide rollers comprising:
• at least one group of at least two pressing rollers which are configured to press against a first side of one of the endless conveyor belts at two or more positions, and
• at least one support roller which is configured to press against a second, opposite side of the conveyor belt, and
• at least one support member on which the at least one group of at least two pressing rollers is rotatably disposed, the at least one support member being mounted on the support frame rotatably relative to a rotation point;
• and
• a support member retracting mechanism configured to displace the at least one support member with the pressing rollers rotatably disposed thereon in an axial direction.
