Abstract: Apparatus for conditioning plant material in the production of hay. The apparatus comprises a conditioning part (12) through which plant material can be passed to be subjected to compression for fracturing the stalks thereof. The conditioning path (12) has an intake end (21) and a discharge end (23). The conditioning path (12) is defined between two compression surfaces (26, 28), one of which is defined by an endless beam (25) moveable through a cyclic path about rollers (31, 32). The rollers (31, 32) are mounted on a common support (33). The compression surfaces (26, 28) are arranged for movement with respect to each other for varying the size of the intake end (21) relative to the discharge end (23). Typically, the common support (33) for the rollers (31, 32) comprises a beam (33) which is angularly moveable, and wherein control means (43) are provided for controlling angular movement of the beam (33).

Abstract: A fluid mixer includes an elongate mixing chamber having an inlet system at one end for admission of liquid and gas to be intimately mixed by passage through the chamber and an outlet for the mixture at the opposite end, wherein opposed longitudinal sides of the chamber are each defined by a surface of scallop shape having peaks and troughs, with the peaks of the two surfaces being relatively offset so as to cause the liquid and gas entering the chamber to flow along a generally sinuous path through the chamber to create a turbulent flow which promotes intimate mixing. Advantageously a UV source extends within the chamber to sterilize the liquid flowing through the chamber.

Abstract: A mobile frame (10) for supporting an elongate flexible structure (11) such as a ground working tool assembly, the mobile frame (10) is foldable between a first position in which the elongate flexible structure (11) is supported in a working condition in relation to the ground, and a second position in which the elongate flexible structure (11) is supported in a stored condition in relation to the ground. The mobile frame comprises a first frame portion (31) supported for movement over the ground and a second frame portion (32) for supporting one end of the elongate flexible structure. The second frame portion is mounted on the first frame portion for folding movement with respect thereto about a pivot axis inclined to the fore-and-aft axis of the mobile frame such that the spacing between the ends of the elongate flexible structure (11) increases as the elongate flexible structure is moved from the first position to the second position.
