<p>A spraying device has a pair of side pieces 6 joined together at the top 7 and inwardly directed spraying heads 9 which are caused to oscillate about horizontal axes to vary the direction at which spraying solution is applied to a plant located between the side pieces 6. When the device is movable on wheels 5, the oscillation of the heads 9 can be caused by a drive 10 from the wheels 5. Rear doors 8 close in the chamber formed by the side pieces 6 and are openable to allow plant 15 to exit from the chamber. The device can be drawn by a tractor 3 whose power take off can be used to drive the heads 9.</p> |
