Abstract: An agricultural machine for picking up and chopping crop, particularly green crop such as grass to be made into silage, and comprising a picking up device for collecting crop from ground over which the machine is travelling and at least one chamber to which the crop is delivered from said picking up device through a lateral opening and the chamber containing a reciprocable ram movable towards and away from stationary knives in an open end of the chamber, the ram preferably having knives on its face presented towards the stationary knives, the movement of the ram towards the stationary knives causing the knives to co-operate to chop up the crop, the cut crop being discharged from the open end of the chamber into a collector cage.

Abstract: A pipe-bending apparatus comprises an elongate structure having a longitudinal work surface at, or adjacent to, opposite ends of which clamping means and a former are respectively mounted. The former is held fast on the work surface, and the clamping means is power-driven towards and away from it by a double-acting hydraulic ram. A series of formers are provided, each having, in plan, a semi-circular anvil mountable to face the clamping means. The anvils are each of concave vertical cross-section and of different radius from one another, with peripheral walls to locate a pipe in position in the anvil during a bending operation. The ram is supplied from a tank containing a hydraulic fluid tank which--together with the necessary hydraulic pump and electric motor--is mounted beneath the work surface.
