ISrOE.MAL day's WORK IN WESTERN NEW YORK. 



hard, stony, lump}", or so occupied with stumps as to render the spike- 

 tooth or disk harrow ineffective. On account of its heavy draft it 

 can not be used in such extreme widths as can the spike-tooth harrow. 

 Three horses are more suitable than two on even the narrowest 

 widths, wliile a 4-horse team finds an 8-foot or 9-foot spring-tooth 

 harrow a heavy load.

Li Table YI is shown the daily averages for the disk harrow with 

 2-horse, 3-horse, and 4-horse teams working on fresh-plowed and on 

 well-packed land, respectively. It appears that with two and three 

 hoi"ses, increasing the width of the disk harrow does not result in any 

 great increase in acreage disked. This is more true on fresh-plowed 

 than on well-packed land. Where four horses are used, mcreasing 

 the width results in more marked increases in daily accomphshment. 

 The heavy draft of the disk harrow accounts for the lack of increase 

 in results with increasing width where 2-horse and 3-horse teams are 

 used. The implement is an overload, as a rule, for anything less 

 than four horses; so that any increase in width with the smaller units 

 of power results in less speed and mileage per day.
