Abstract
A ballast weight for use on agricultural or industrial machines such as tractors, the weight being provided with a cut-out which opens through one edge and which receives part of a mounting frame attached to the machine. The weight is retained in position on the mounting frame by shaping the upper portion of the cut-out adjacent the opening to form a lip which can be hooked behind an upper part of the frame and by a linearly slidable latch member which is housed in a cavity provided in that portion of the weight which defines the lower portion of the cut-out. One end of the latch member projects from the upper end of the cavity into the cut-out and is arranged to automatically engage a locating formation on the lower part of the mounting frame under the action of a spring bias when the weight is brought into its operational position. The other end of the latch member is provided with an operating means, such as a finger hole or ring, which projects from the lower end of the cavity and enables the latch member to be linearly displaced within the cavity against the bias to disengage the frame thus enabling the weight to be removed from the frame.
