Abstract

A tower and wheel arm assembly for an implement frame includes a pair of identical single piece pivot castings which are selectively connectible at different locations along the frame and provide both wheel arm pivoting and a cylinder anchor tower pivoting. The wheel arm axle extends between the castings pivots within cylindrical cavities located in the castings. External cylindrical surfaces concentric with the cavities rotatably support a pair of tower plates which include circular openings received over the external cylindrical surfaces. Casting symmetry allows the same part to be used interchangeably for either the right-hand or left-hand support.

Dependent claims

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.
