1. A ground roller for being supported on a land roller implement for chopping vegetation on the ground, the land roller implement having a main frame arranged for connection to a towing vehicle for movement in a forward working direction with the towing vehicle, the ground roller comprising:
a drum body having an outer periphery which is generally cylindrical about a drum axis and being arranged to be supported on the main frame for rotation relative to the main frame about the drum axis in which the drum axis is oriented transversely to the forward working direction for rolling movement across the ground in the forward working direction;
a plurality of mounting flanges supported on the drum body so as to extend at least partly in an axial direction of the drum body and so as to protrude outward from the outer periphery of the drum body, each mounting flange being welded to a peripheral surface of the drum body at a leading face of the mounting flange by a plurality of weld beads at respective weld locations spaced apart in the axial direction of the drum body;
a plurality of blades supported on the leading faces of the mounting flanges respectively using fasteners coupling the blades to the mounting flanges such that each blade extends radially outwardly from an inner end to an outer end which is spaced radially outwardly in relation to the respective mounting flange;
the inner end of each blade including at least one protruding portion defining an innermost edge of the blade and at least one recessed portion forming a raised inner edge of the blade which is raised radially outward from the drum body relative to the innermost edge of the blade; and
each weld bead of each mounting flange being aligned in the axial direction with said at least one recessed portion of the respective blade supported on the mounting flange,
wherein the protruding portions are separable from the mounting flanges together with the blades upon removal of the fasteners.
