Claims20
A ground driven agricultural wheel in the form of a press wheel or press harrow, comprising
- a helical spring coil having
- a first end located at a first end of the coil,
- a second end located at a second end of the coil,
- the first end being a different end to the second end, and
- windings extending between the first end and the second end to form the spring coil,
- the windings of the coil being flexible so as to be relatively movable with respect to one another in response to flexing movement of the coil,
- the first end and the second end being mounted to a hub assembly,
- wherein the first end is mounted to the hub assembly by an articulated link,
- the articulated link providing relative movement between the first end and the hub assembly to vary the relative distance between the hub assembly and the first end.
