EXPERIMENT STATION REPORTS.

The table below shows the average number of horses released on dif- 

 ferent sizes of farms up to 320 acres of cultivated land, beyond which 

 there are too few farms reported to give a fair average. 



HORSES USED BEFORE AND AFTER PURCHASE_OF TRACTOR 322 TRACTOR FARMS. 



The table below shows the possibility of the farmer adding to his crof^^ 

 acreage with the purchase of a tractor. In cases where the farmer is not 

 operating to capacity the tractor should enable him to add a considerable 

 acreage to the amount he is now working. 



Group 1 consisted of IG farms with an average crop acreage of 141.3 

 before tractor was purchased, while group 2 compriised 86 fanns 

 averaging 174.7 acres. The farmers of group 1, changed their power 

 factors practically the same as group 2, and in addition increased their 

 crop acreage an average of 60.1. The data would indicate that Avhere 

 farmers are not operating up to capacity they might reasonably expect 

 to operate more land with the purchase of a tractor. 



THE POSSIBILITY OF INCREASING CROP ACREAGE WITH TRACTOR PURCHASE. 



The following data were secured on the rate of doing some of the farm 



operations.
