LOW-VACUUM 
MILKERS

For more than 7 years, Hinman has pioneered the idea 
of low-vacuum milking. That principle has now been thoroughly 
established, but it took years of research and thousands of tests 
to find the exact degree at which a cow milks best. Hinman 
found it—at 10 inches. Vacuum at 10 inches safely empties the 
udder faster.....Besides, it makes the cow comfortable, and en- 
lists her cooperation....Its mild action helps keep teats and ud- 
ders in good condition—that’s why so many Grand Champion 
cows for years have been milked exclusively with Hinman Milk- 
ers. :
