Patent ID: 7182146

Claim:
A constraint assembly in support of a plurality of hoses associated with operation of an agricultural implement, the agricultural implement including a main frame having a telescoping hitch assembly configured to be coupled to a tow vehicle, the telescoping tongue assembly having a hitch arm configured to move in telescoping relation to an extended position and a retracted position with respect to a stationary arm of the telescoping tongue assembly, the constraint assembly comprising: a first linkage having a first end and a second end, the first end of the first linkage pivotally connected about a vertical axis at the stationary arm of the telescoping tongue assembly; and a second linkage having a first end and a second end, the first end of the second linkage pivotally connected to the second end of the first linkage, the second end of the second linkage pivotally connected about a vertical axis at the hitch arm of the telescoping hitch assembly; wherein: in a field operative position of the constraint assembly, the first linkage and the second linkage fold in a rearward direction relative to a forward direction of travel of the agricultural implement; and the first linkage includes a first arm in parallel relation to a second arm and at least one hose coupling assembly connected therebetween so as to pivot independently relative to the first and second arms.
