Abstract
An agricultural sprayer suspension includes four generally identical independent strut suspension assemblies each having a pneumatic spring supported above a strut shaft which is received within a strut journal connected to an adjustable axle. A scissors assembly located above the axle maintains wheel steer while facilitating vertical movement of the strut shaft within the journal. On non-steerable wheels, the lower end of the scissors assembly is connected to the journal to maintain a preselected wheel orientation. For steerable wheels, the lower end of the scissors assembly is connected to a hydraulic steering structure which allows axle adjustments for varying wheel tread. Similar construction of the steerable and non-steerable wheel assemblies reduces the number of different parts required and facilitates selective construction of sprayers with either two-wheel or four-wheel steering. A centrally located cab and sloping hood structure provide good visibility and direct viewing of all four wheels.
