able from the stable floor by pressing 

 an electric switch. Since the sides of 

 the crib would be less than 4 feet high 

 it could be filled in the early feeding 

 period by raking the hay downward. 

 At a later period, filling the crib 

 would require more hand work. 



Long Hay 



In getting long hay out of the mow, 

 the oversized hay chute previously 

 described can be used to advantage 

 in some barns. The crib with a mov- 

 ing wide belt will be effective where 

 free mow floor space is available near 

 the trap door leading to the feed al- 

 ley. The canvas hammock described 

 under chopped hay can be loaded in 

 advance and then unloaded by pull- 

 ing the rope from the feed alley floor. 

 Where long hay must be carried long 

 distances in the mow, special arrange- 

 ments may be made to use the regu- 

 lar hay carrier and track system. Me- 

 chanical power (Fig. 29) could be 

 used to raise several hundred pounds 

 of hay any desired height from the 

 mow and carried along the barn and 

 dumped as desired. This procedure 

 can be perfected by engineers. 



In barns of the Fig. 23 arrange- 

 ment, a wooden platform on low 

 wheels could be used near the end of 

 the winter feeding period to trans- 

 port hay from the far end of the barn. 

 Small quantities of long hay, of 

 course, can be pushed fairly conveni- 

 ently along a smooth mow floor. In 



several instances, operators had in- 

 stalled hay mow driers in such a way 

 that the operator had to carry hay 

 rather than push it. More time and 

 greater eff'ort were required. 



The task of getting hay out of the 

 mow to the feed alley floor involves 

 more travel and becomes more impor- 

 tant as the size of the herd increases 

 and consequently different practices 

 must be considered for a very large 

 herd. For instance, the man with 60 

 cows, handling half a ton or more of 

 baled hay a day, might use his truck 

 to transport a week's supply of hay 

 from the mow to a more convenient 

 small storage near the feed alley. 

 Under these conditions the hay can 

 be kept in temporary storage some 

 distance from the stable, and supplies 

 trucked in once a week. 



In some cases, special arrangements 

 can be made for one or several con- 

 venient storage spaces adjacent to the 

 feed alley and so located that they 

 can be filled easily from the mow. For 

 instance, if the cows face in, a room 

 at the end of the barn can sometimes 

 be provided. If the cows face out a 

 room on each side of the barn is con- 

 venient. Sufficient supplies of hay 

 for two or three days can be stored 

 in these rooms and pushed out as 

 needed.
