MINUTES OF 



Oti the Use of the Couch Grass Drag. 



When all the couch grass is collected by the operation of the common 

 harrow, after the second plt^ghing has been given, then is the time for using 

 this machine. 



Drag the land the length way of the ridges, then harrow it once or 

 twice, at the same time collect the couch grass- into rows as much as possible 

 with the harrows; roll the land, and then gather the couch grass into heaps by^ 

 the couch grass rake, (hereafter described) and burn it. 



If the land is very full of couch grass, it may be proper to drag it across 

 then harrow and roll as before, and afterwards gather the couch grass into heaps 

 again by the rake, and burn it. 



Plough the land the third time, and if any more couch grass turns up, 

 harrow, drag, roll, and rake it once or twice, before the fourth ploughing. 



If the coulters gather much of the couch grass, they should be cleaned 

 occasionally.' 



In cleaning the coulters, one man lifts up the side of the drag by one of 

 the handles, while the other man knocks the couch grass off the coulters with 

 the other handle.
