the number of rippers and their particular location along the frame is optional the scoop 3 specifically comprises a pair of substantially part circular side plates 13 which are joined e g by welding to opposite axial ends of a trough shaped substantially half circular cylindrical member 14 as shown in the figure the diameter of the side plates is substantially equal to the diameter of the half cylindrical member the pair of side plates are however angularly offset relative to and about the axis of the half cylindrical member in the clockwise direction thereby producing a scoop lip 15 at one circumferential end of the half cylindrical member to which a transverse blade 16 e g made from hardened steel is attached a scoop opening 3a is formed above the lip 15 and between the side plates 13 through which dirt or any other material may be loaded into the half cylindrical member 14 each of the part circular side plates 13 are reinforced by a pair of steel reinforcing members 17 18 the reinforcing member 17 is secured along a diameter of the side plate 13 while the reinforcing member 18 is secured to the side plate 13 substantially perpendicularly to the member 17 the pivot axles 4 on either side of the scoop 3 are rigidly secured to the reinforcing members 17 when the scoop is pivoted such that the reinforcing member 17 is oriented vertically the scoop 15 is substantially horizontal and that the blade 16 occupies a position.
