  • Patent number: 8764042
    Abstract: A pull-type agricultural implement has a beam with drawbar hitch pivotable relative to the beam about a vertical axis and a horizontal axis extending in the travel direction. The drawbar hitch has a receptacle for a tractor drawbar. The receptacle enables pivoting of the drawbar about an axis that is horizontal and transverse to the travel direction relative to the drawbar hitch in a locked position. Guiding and adjusting plates in the receptacle allow adjustment of the receiving width of the receptacle to different drawbar dimensions. From a first position, in which the plates limit lateral play of a drawbar with large cross-section relative to the travel and working direction to a minimum, the guiding and adjusting plates are transferrable and lockable in a second position, in which the plates limit lateral play of a drawbar with small cross-section relative to the travel direction to a minimum.
