[AT] Old IH hammer mill

[Larry D. Goss]

10-inch is about the size ours was too, Ralph.  We had fixed hammers
that were about 1/4" thick (6 mm).  They were arranged on paired spokes
every 90 degrees.  Now, I run an 8-hp Bear Cat chipper/shredder that
uses mower knife sections to do the cutting.  Knowing how much finer the
ground material comes out compared to the size of the holes in the
screen, it would probably be acceptable to run grain through the Bear
Cat for livestock.  Tomorrow, I've got to get it out and set up for
turning the magnolia leaves into mulch.  As a part of the last tractor
deal I made, I acquired the remains of a 3-point mounted Trac-Vac.
Yesterday, I traded for the remains of a brand-new Trac-Vac that is
missing the engine.  Since the engine and the mount are about all that
was left of the original one, I'm going to be able to put together a
system for blowing or collecting leaves, mice, dead birds, and stray
cats!  I worked a couple of hours on it tonight and will pick up new
ignition components tomorrow to get that much of it back in condition.
I'll replace the gas tank, clean out the carburetor, and then I'll be
ready to start the engine.  I would normally flush the rust out of the
tank rather than replace it, but I already have one in my "inventory" so
I may as well use it.

Hi Larry
Thanks for the reply. Thought maybe my question had caused the list to 
crash as yours is the only message I have seen all day.
I never knew David Bradley made a hammer mill. Most of the major machine

companies made them up here and they were all much the same design. This

IH is only a ten inch compared to the 14 inch Case I have been using 
forever. Same general design as yours, flip up hood to change screens. 
Funny thing about those screen hole diameters, we always used the small 
hole screen (maybe half inch) for oats chop and then changed to the big 
(about two inch) hole screen for straw and hay. The small hole screen 
wore so thin that I quit using it and just left the large hole screen in

for grain. Surprisingly it still makes chop just as good as the small 
hole screen did, and probably at increased capacity.
The major difference this IH has from the Case is the style of hammer. 
The Case had solid, four sided hammers arranged on "spokes", about six 
rows if I recall right. The IH has swinging hammers, much like a combine

straw chopper.
I checked my machinery brochures from way back and Case was only 
offering a p.t.o. hammer mill by 1961. Guess belt drives were becoming 
obsolete by then. IH did not even show a hammer mill in their catalogue 
by 1963.
