MAKING THE SOIL PRODUCE CROPS 



rows, cultivators, mowers, fertilizer distributors, 

 planters, sowers and seeding accessories. The 

 prices of these vary according to make and 

 quality. Levers are provided for adjusting the 

 depth of plowing, cultivating and seeding. Some 

 of the large type garden tractors are equipped 

 with a seat on a sulky attached to the machine 

 so that the operator can ride and have complete 

 control over speed and the type of work he 

 wishes to do. A modern garden tractor will 

 be found very useful in taking care of a lawn 

 or garden. In the case of larger areas under 

 cultivation, but not of field size, this type of 

 machine is rapidly gaining popularity for per- 

 forming efficiently and economically the numer- 

 ous jobs that are to be done on every small 

 farm.
