Abstract: An apparatus (10) for distributing solid material such as manure or fertiliser is disclosed. The apparatus (10) has a container body (11) mounted to a chassis and conveying means (17) to move the material from a first end of the container body (11) to a second end. The second end is at least partially open and opens onto one or more rotating augers (14A) the axis of the or each auger (14A) being orientated substantially vertically. Cutter blades (91) are included, orientated radially with respect to the auger axis, which blades (91) can have a trapezoidal shape. The auger (14A) has a helical auger flight (92) of generally circular shape when viewed along the axis of the auger (14A). The circumference of the auger flight (92) has one or more cut-outs (81) whose edge lies on the circumference of a circle or ellipse.
