Method 38. 
This large crew is very efficient and makes over 1,000 acres of 
prairie hay each year. Each member of the crew puts in a full day 
every day. The cost per ton is low, because men and horses are well 
used to the work and there is no lost time. One more man is used on 
the stack than is customary when only three sweep rakes are used. 
This crew will put up 450 acres of tame hay in a 10-day season. The 
field is raked twice.

Fourteen men and 20 horses put up 67.5 tons (45 acres) per day. Yield, 1.5 tons per acre. Man-hours 2, 
team-hours 1.48 per ton. Labor cost, per ton, $0,690. 
Method 39. 
The labor cost per ton for this method is high, $1.55 per ton. 
This is not due to poor crew management, but to the low yield per 
acre (only half a ton), necessitating twice the number of mowers and 
rakes to harvest a given amount of hay as would be required for a 
yield of 1 ton per acre. It will be noticed that while a sweep rake 
handled 12 tons per day, it must cover 24 acres to get this amount. 
To cover this area, a sweep must be kept on the jump every minute. 
This crew puts up 4,000 tons of prairie hay in Colorado.
