An agricultural application machine (10) comprising a pair of wheels (11,12) each having an associated wheel support structure (22) is provided. Each wheel support structure is mounted to the chassis (60) by a transversely extending support shaft (29;49) which is slidably mounted within a bearing block (27;47). The provision of bearing blocks allows the transverse separation of the wheels to be varied with minimal sliding friction. |
