It is used for sharpening the mower knives. Usually it 

 has a double-beveled emery wheel which will grind two 

 sections of the knife at the same time. The emery wheel 

 is given a high rotative speed by means of gearing or 

 sprocket wheels and chain (Fig. 124). 



RAKES 



245. Development. The introduction of the mower created 

 a demand for something better and with a greater capacity than 

 the ordinary hand rake. As long as hand methods prevailed in 

 the cutting of the grasses there was little need for anything 

 better than the hand rake. The first horse rake was revolving. 

 It did very satisfactory work when carefully handled. But later 

 in the steel tooth rake there was found a much better tool. To 

 Walter A. Wood Company, of Hoosick Falls, New York, is 

 given the credit for bringing out the first spring-tooth rake. 

 Differing from the modern tool, it was made almost entirely 

 of wood except the teeth. The early rakes were dumped entirely 

 by hand, but later an internal ratchet was provided on the 

 wheels, which engaged a latch operated by the foot, and which 

 carried the rake teeth up and over, thus dumping the load. 

 The early rakes were almost universally provided with thills.
