MACHINES FOR THRASHING AND WINNOWING. 117 to be sometimes inconvenient when the land is very full of weeds. In such cases, an instrument with coulters alone may be beneficially employed. The following figure represents a machine of this It is formed, like the last, of iron. In the centre is a coul- ter : and, attached to the beam, by hinges, are two bars, into each of which are inserted two coulters. The bars can be set at a greater angle to the beam, and consequently the coulters made to extend over a greater space and till a wider interval. Near the fore-end of the beam is a wheel, the purpose of which is to steady the motion of the machine ; and there is sometimes behind another wheel, which adds to the effect, but which is not indispensable. By removing the wheels, bars, and coulters, and attaching the apparatus shown in Fig. 40, the machine is converted into a double mould-board plough.
