1. A spiker roller having:
- (i) a roller assembly having a plurality of roller components each having a peripheral wall and a plurality of apertures in the peripheral wall and an end wall which has a centrally located hub or boss surrounding an opening, wherein said hub or boss has an end portion remote from the end wall which extends outwardly from the peripheral wall to define a spacer;
(ii) a multiplicity of spikes which are each releasably retained within a respective aperture of each roller component; and
(iii) a support shaft which is insertable through the opening in each roller component, wherein each of the roller components when mounted on the support shaft is separated by said spacer being configured to engage with the end wall of one roller component adjacent thereto so that each roller component can rotate independently of each other;
wherein the peripheral wall has a plurality of flats each incorporating a respective aperture and each apertured flat has a planar inner surface and a planar outer surface through which aperture a respective spike extends.

7. A roller component for a spiker roller having a peripheral wall and a plurality of apertures in the peripheral wall and an end wall which has a centrally located hub or boss surrounding an opening, wherein said hub or boss has an outer end portion remote from the end wall which extends outwardly from the peripheral wall to define a spacer whereby in use an adjacent roller component is separated by said spacer being configured to engage an end wall of the adjacent roller component so that said adjacent roller component can rotate independently of the roller component and wherein the peripheral wall has a plurality of flats each incorporating a respective aperture and each apertured flat has a planar inner surface and a planar outer surface through which aperture a respective spike extends.
