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.
A harvesting cutter assembly comprising a tractor tool bar, generally horizontally extending housing means below the tool bar, a rotary cutter blade supporting disc journalled in said housing means with its peripheral portion extending outwardly from said housing means, cutting blade means on said peripheral portion, means to yieldably connect said housing means to the tractor tool bar and including means biasing said housing means downwardly, and ground-engaging skid means positioned underneath said supporting disc and on the bottom of said housing means and acting to limit the position of said cutting blade means to a substantially constant height above ground level while preventing said cutting blade means from penetrating the soil.
