Improved cutting assembly

A cutting wheel assembly comprising:

• a frame having two spaced support pillars, each pillar having an upper portion, an intermediate portion and a lower portion, the intermediate portion arranged at an angle to the upper and lower portions;
• and
• a pair of outer cutting wheels arranged on either side of an inner cutting wheel, wherein the outer cutting wheels and the inner cutting wheel are each supported on the lower portions of the support pillars in a rotatable manner about a common axis of rotation,
• wherein each of the outer cutting wheels and the inner cutting wheel having a central hub portion about which an annular cutting portion is provided, each annular cutting portion having a respective cutting diameter,
• wherein the inner cutting wheel has a different cutting diameter than that of both the outer cutting wheels, and the central hub portions of neighboring cutting wheels defining a respective gap in which the intermediate portion of a respective pillar is received, and
• wherein at least one of the annular cutting portions of the inner cutting wheel and/or the outer cutting wheels has one or more rim portion(s) that overlap each gap, so the annular cutting portions of the cutting wheels provide a cutting action along a continuous line of cut in a lateral direction.
