ABSTRACT:
A non-soil penetrating sugar cane harvesting blade assembly adapted to be connected to a tractor tool bar and consisting of top and bottom circular housing members with a rigidly-connected central shaft on which is journalled a disc member extending beyond the rim portion of the housing members and having cutting blades secured to its periphery. A ground-engaging skid is secured to the bottom housing member and maintains the cutting blades at a constant cutting height. A hydraulic motor is mounted on the top housing member and is drivingly connected to the disc member. The disc and housing members are linearly guided for upward and downward movement relative to the tool bar, and are biased downwardly by a spring acting between the top housing member and the tool bar and supported on an upstanding post member secured on the top housing member. One or more shock absorbers cushion relative movement of the cutter housing assembly with respect to the tool bar. The disc has asbestos-lined peripheral guide rings located respectively above and below the rim portion of the housing members.
