Abstract
A work vehicle () comprises a coupling apparatus () for coupling an attachment to the forward end () of the work vehicle (). The coupling apparatus () comprises a three point linkage mechanism having a pair of lower coupling elements () and an upper coupling element (). A first carrier element () is pivotally coupled to a forward chassis part () of the work vehicle () by a pair of main transverse pivot shafts () which define a main transverse pivot axis (). A second carrier element () carries the lower coupling elements () and is pivotally coupled to the forward chassis part () about the main transverse pivot axis () and about a main longitudinal pivot axis (). A main longitudinal pivot shaft () extending rigidly from the second carrier element () pivotally engages the first carrier element () and terminates in a swivel bearing () which pivotally and swivelably couples the main longitudinal pivot shaft () to an intermediate transverse pivot shaft () which also defines the main transverse pivot axis (), so that the second carrier element () and the first carrier element () are pivotal about the main transverse pivot axis (), and the second carrier element () is pivotal about the main longitudinal pivot axis () to facilitate upward and downward movement of an attachment coupled to the coupling apparatus () about the main transverse pivot axis () and tilting movement of the attachment about the main longitudinal pivot axis ().
