This ensures that the use of a separate header trailer is not necessary. At the same time such a rotating mechanism enables support wheel arrangements to be brought quickly from a working to a non-working position without heavy physical work being required for that alteration.1/4 CIDD 00c 0)0 CNC3/4 UL0 0 u')) pqp
