unit, through its ease of operation, 

 offers the greatest incentive to the 

 operator to load his harrow for even 

 the shortest hauls. A few similar 

 units are already in use on New Eng- 

 land farms. We have been able to 

 study the process of construction and 

 its use under operating farm condi- 

 tions. When these studies are con- 

 cluded, plans and construction in- 

 formation will be made available to 

 farmers. Farmers with a different 

 type of harrow carrier may prefer 

 their designs, but the important thing 

 is to save harrow maintenance costs 

 by using some type of carrier.

Front Opening Type 



Milk Cooler Shows Promise 



A comparison of the front open- 

 ing type of milk cooler with the com- 

 mon immersion type shows several 

 advantages for this newer machine. 

 The front opening cooler, sometimes 

 called the side opening cooler, re- 

 duces the temperature of the milk to 

 less than 50°F in one hour, which 

 is only three to eleven degrees higher 

 than that cooled by the immersion 

 type in the same length of time. 



Performance of the front opening 

 cooler is equal to the immersion 

 cooler except where it is desirable to 

 cool the milk to temperatures below 

 50°F in cases of high initial bac- 

 terial count or where the milk is to 

 be held longer than 24 hours. 



Convenience seems to be the major 

 attraction for the front opening 

 cooler. Only a four to six-inch lift 

 is necessary in handling the cans. 

 These coolers are narrower and are 

 adapted to narrow doors. There is 

 no manipulation necessary to main- 

 tain the proper water level. Pits are 

 discouraged by boards of health and 

 are being eliminated. 



Operating costs are about equal 

 for the two types. Power consump- 

 tion varies more among makes of 



coolers than it does between the two 

 types studied.

Home Made Conveyors 



Save Time and Labor in 



Removing Baled Hay from the Mow 



Two types of conveyors which can 

 be easily constructed in the farm 

 shop have been developed at the 

 University to reduce the labor re- 

 quirements for moving baled hay out 

 of the mow. One of these conveyors 

 uses gravity, and the other is powered 

 by a fractional horsepower electric 

 motor. 



These conveyors may be used sep- 

 arately or in combination with each 

 other. By using one of these con- 

 veyors, ten or twelve feet long, to 

 move baled hay from the pile in the 

 mow to the hay hole or feeding floor 

 a man can save 20-25 feet of travel 

 per bale. In some cases conditions 

 may be such that the conveyor can 

 be preloaded for the next feeding 

 and eliminate one or more trips to 

 the mow each day by having a switch 

 or release on the feeding floor. Some 

 farmers who use one of the many 

 types of bale elevators now marketed 

 to put their hay into the barn could 

 use the home made conveyors to 

 carry the hay farther back in the 

 mow at haying time. 



The gravity feed conveyor is made 

 up of rollers about two feet long, 

 spaced between six and ten inches 

 apart (depending upon the diameter 

 of the rolls ) . and supported by a 

 2" x 4" on each end. The rolls can be 

 made from either 4" x 6" aluminum 

 irrigation pipe or 4" bituminized- 

 fibre drain pipe. The cost of materi- 

 als for one of these conveyors 10 

 feet long varies between $15 and $35 

 depending on the size, type, and 

 spacing of rolls. These can be made 

 in sections 10 to 12 feet long and 

 joined together to form a contiini- 

 ous conveyor.
