THE ADVANTAGES OF STEAM CULTIVATION. 



roller, or with roller and harrows. The frame is hinged in 

 the middle, and can be readily taken to pieces, so that, in 

 moving from field to field, the two halves are pulled one 

 behind the other, any difficulty in moving this broad imple- 

 ment about being thus effectually overcome.

COMBINED STEAM DKILL AND HARROW. 



The great drawback to steam drilling has been that even a 

 drill of the largest width admissible under ordinary circum- 

 stances requires only a fraction of the power which is at the 

 disposal of the engines generally supplied for cultivating 

 operations. Only by combining other operations, such as 

 light cultivating and harrowing with drilling, can the power 

 be advantageously applied. 



For this reason the steam drill is combined with a light 

 cultivator or heavy harrow in front of the seed-coulter, and 

 a light seed harrow following the same. Thus, three distinct 

 operations are performed in going over the land once. 



Fowler's Steam Drill has a total width of 9 feet. In turn- 

 ing round, the heavy harrows are lifted by the power of the 

 engine, and the whole implement moves at once on new 

 ground, the same mechanical principles being applied as in 

 the turning cultivator previously described. 



The advantages of this combination are very great, for 

 when the land is prepared, 30 acres and upwards a day are 

 efficiently drilled and harrowed without the trampling of the ' 

 seed-bed with the horses' feet.
