Notes – The rules of floating drawbar and hydraulic hook repositioning from addi-
tional into operating position in combined drawbar, floating drawbar and hydraulic hook re-
placement from operating position into additional position, floating drawbar installation into
one of two positions along the length and into one of three transversal positions are given
in subsection 4.4.14 “Repositioning of floating drawbar and hydraulic hook in combined
drawbar”.
