1 Percentages based on number of owners who would buy another combine when present one is worn 
out or becomes obsolete. 
Approximately 24 per cent of the owners of 9-foot combines recom- 
mended one of this size, because its operation required a small crew 
and was suitable for their particular size of farm. The tillable 
acreage of these farms ranged from 445 to 700 per farm, and averaged 
672. On the other hand 57 per cent of the owners of the 9-foot com- 
bine favored the 12-foot size, giving as reasons that it has a leveling 
device, and that with the same number of men one of this size will 
do more work in a given time than the 9-foot size. 
All but one of the owners of 12-foot combines said that they would 
buy another when needed and 57 per cent recommended this size. 
Their reasons were that it would cut their grain in season and was 
best adapted to their size of farm. These farms ranged in size from 
460 to 1,048 tillable acres and averaged 987 tillable acres per farm. 
Of those owning 14-foot combines all but one recommended the 
purchase of another when needed. Thirty-three per cent of this 
group said that they would buy a 16-foot combine stating that, with 
the same crew, one of this size would do more work than a 14-foot 
combine; 67 per cent recommended the purchase of another 14-foot 
combine for the reason that one of this size was best suited to their 
size of farm. ‘These farms ranged in size from 600 to 1,000 tillable 
acres and averaged 790 tillable acres per farm. 
All of the owners of 16-foot combines recommended the purchase 
of a combine of this size. One man stated that it was a good size 
for his 28-horsepower tractor, and another said that a combine of 
this size was large enough to handle his crop and worked well on 
steep land. The range in tillable acres per farm for those men who 
recommended 16-foot combines was from 541 to 2,240. The average 
size was 1,199 tillable acres per farm. 
Approximately 14 per cent of the owners of 18-foot combines rec- 
ommended the purchase of a 12-foot combine, and 79 per cent recom- 
mended the purchase of an 18-foot combine. The tillable acreage 
for those men who recommended 18-foot combines ranged from 700 
to 2,570, and averaged 1,106 acres per farm. These men were satis-
