Abstract:
1. A cutting machine comprising: an elongate tool carrier mounted to a machine body at a machine-proximate end and having a rotatable cutting tool mounted at a distal end thereof; a drive member positioned adjacent to and concentric with the rotatable cutting tool at the distal end of the tool carrier, the drive member being mounted on a rotatable bearing assembly received in an aperture at the distal end of the elongate tool carrier; a machine-proximate receiving space defined between two side walls of the elongate tool carrier, said machine-proximate receiving space configured to accommodate a continuous drive loop power transmission operatively engaged between the drive member and a drive motor at the machine body, said machine-proximate receiving space extending from the machine body to at least a perimeter of the rotatable cutting tool; a distal receiving space defined between two side walls of the rotatable cutting tool, said distal receiving space configured as an extension of the machine-proximate receiving space, said machine-proximate receiving space and said distal receiving space together constituting a protective operational space for a continuous drive loop power transmission operatively engaged between the drive member and a drive motor at the machine body; and at least one side of the elongate tool carrier has at least one rim section formed thereon to form a shelter for the power transmission.
