摘要：
A work vehicle (1) comprises a coupling apparatus (18) for coupling an attachment to the forward end (8) of the work vehicle (1). The coupling apparatus (18) comprises a three point linkage mechanism having a pair of lower coupling elements (19) and an upper coupling element (25). A first carrier element (22) is pivotally coupled to a forward chassis part (14) of the work vehicle (1) by a pair of main transverse pivot shafts (35) which define a main transverse pivot axis (33). A second carrier element (23) carries the lower coupling elements (19) and is pivotally coupled to the forward chassis part (14) about the main transverse pivot axis (33) and about a main longitudinal pivot axis (45). A main longitudinal pivot shaft (46) extending rigidly from the second carrier element (23) pivotally engages the first carrier element (22) and terminates in a swivel bearing (50) which pivotally and swivelably couples the main longitudinal pivot shaft (46) to an intermediate transverse pivot shaft (54) which also defines
