Coupling arrangement for twin agricultural trailing disc harrows - consists of trapezoidal traverse which swings from working position with harrows side by side into line-ahead position

摘要: The coupling arrangement is for twin agricultural trailing disc harrows (A,B). It consists of a horizontal traverse (1) yoked to shafts (2) and coupled at each end (10,11) the trapezoidal with centre member (14) two legs (13,15), its width overall embraces half trailer (A) when line couplings parallel axis (M) (A). Near (10) two-bar linkage (3). USE/ADVANTAGE - When not working form single behind tractor coupling.
