| 21. An assembly for an ice-removing device for removing ice from a ground surface, the ice-removing device being adapted to
be mounted to a mobile support, the assembly comprising:
an ice cutting mechanism having a first axis, said ice cutting mechanism being adapted to be transversally mounted on the
mobile support, said ice cutting mechanism being operative to cut a plurality of parallel strips in the ice from the ground
surface;
at least one ice crushing mechanism having a second axis, said ice crushing mechanism being adapted to spin on said second
axis, said ice crushing mechanism being adapted to be mounted to the mobile support; and
a depth control system operative to measure a distance to the ground surface and accordingly adjust a distance between said
ice cutting mechanism and the ground surface and independently adjust said at least one ice crushing mechanism, whereby the
at least one ice crushing mechanism is adjustable to an uneven ground surface.
