HARROWING. 



Two types of harrow were used in each district, viz, the spike-tooth 

 and the spring-tooth. The spike-tooth harrow stirs the soil to a mod- 

 erate depth and is the implement commonly used to create a smooth, 

 even surface. Seventy-nine per cent of the growers interviewed used 

 this type of harrow. 



Fig. 8. — Harrowing with a spike tooth. This implement stirs the soil to a moderate 

 depth and is commonly used to create a smooth, even surface. 



The width of the implement varied from 8 feet to 16 feet, with an 

 average of about 9 feet. Fifty-nine per cent used a 1-man and 2-horse 

 crew. This crew size predominated in all sections except northwest- 

 ern Ohio. In this area the width of harrow averaged about 10 feet, 

 and 40 per cent of the men used a crew of one man and three horses.
