Multiple-part attachment for an agricultural machine

A method of moving side frames of a multiple-part frame attachment of an agricultural machine, the multiple-part frame including a central frame portion comprising about half of the total width of the frame and first and second side frame portions each comprising about one-quarter of the total width of the frame, the frame carrying a plurality of row crop dividers including outer row crop dividers at the distal end of each side frame, the method comprising the steps of:

• pivoting the first side frame and the second side frame from a lower working position to an upper non-working position in which the side frames overlie the central frame portion;
• moving the outer row crop divider of each side frame toward its adjacent inner row crop divider so that the outer row crop dividers do not interfere in the non-working position;
• and
• wherein an angle variance decreases as the first side frame and the second side frame move toward the non-working position.

A multiple-part attachment for an agricultural machine comprising:

• a main frame having a plurality of inner row crop dividers;
• first and second side frames each having a plurality of inner row crop dividers and an outer row crop divider;
• means for moving the first side frame and the second side frame from a working position to a non-working position in which the side frames overlie the main frame;
• an adjusting device on each side frame and associated with its respective outer row crop divider for moving the outer row crop divider relative to its adjacent inner row crop divider as the side frames move between the working and non-working positions;
• and
• whereby the adjusting device comprises means for automatically selectively varying an angle between the outer row crop dividers and their adjacent inner row crop dividers so that a position of an outermost tip of the outer row crop divider is automatically selectively varied.
