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. 
fic. 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.
