A roller assembly adapted to follow ground contours during operation, including:
- a pair of roller components, each roller component having a respective inner end connected to the other respective inner end by a flexible and movable primary coupling and each roller component having a respective outer end connected to a support shaft which extends through a hollow interior of each roller component by a respective secondary coupling;
- the support shaft extending through a hollow interior of each roller component and with a clearance through the primary coupling;
- wherein each of the secondary couplings comprises:
- an inner support disc attached to, or integral with, the support shaft at each end thereof;
- an outer support disc attached to, or integral with, the outer end of each roller component;
- fasteners interconnect each of the respective inner support discs and outer support discs to a respective flexible intermediate coupling;
- and
- wherein each inner support disc is spaced from the adjacent outer support disc by a gap there between.
