Abstract:
A wheel arm and tower assembly for mounting on a frame of an agricultural implement, the frame extending transversely to a forward direction of travel of the implement, the assembly comprising:first and second bearing brackets selectively connectible to the frame, the brackets including wheel arm pivot areas and tower pivot areas; a wheel arm assembly including a wheel arm and a wheel arm axle received by and supported in the wheel arm pivot areas for rotation of the wheel arm about a wheel arm axis; an upright tower including lower apertured areas received over and rotatably relative to the tower pivot areas for rotation generally about the wheel arm axis; a cylinder mounted between the tower and the wheel arm assembly for pivoting the wheel arm assembly relative to the tower about the wheel arm axis; and wherein frictional rotational contact between the tower and the tower pivot areas occurs upon rotation of the tower bearing relative to the bearing brackets and is independent of rotation of the wheel arm about the wheel arm axis.
