I have a sears roebuck hammermill, and a previous owner, mounted a shaft with a multiple v belt pulley off to the side, and replaced the wide belt pulley from the hammer drive shaft with a multiple v belt pulley. I belive this was to make it turn faster than 540 rpm. The first shaft that I mentioned, has a normal PTO over run clutch welded on it, and I use a PTO shaft with double splined ends on it to power the mill. I am not much on posting pict's, but will measure the two shives, and axuillary shaft, and give you the info if you E mail me!

I still have a Gehl PTO hammermill. It could be bought wither way, belt or PTO.

I put the jackshaft and pulleys from an MC grain dryer on an old David Bradley hammermill.
If I remember correctly, the RPM is stenciled on the hammermill- "2200-3300".
I can't get it up to speed with a 540 PTO, but can easily do it with 1000.
The slower speed will crack grain, if that's all you want to do, but the blower won't take it away at that speed.

I had one that was converted to PTO from belt. The previous owner welded a frame and tires under it and added a PTO shaft. It was a pretty handy unit and I used it for allot of years. I ground feed for a half dozen steers a year until I brought a grinder-mixer. I brought it at a consignment sale for 35 bucks, sold it years later for 400 bucks. I never thought about what the rpm speed was suppose to be. I just ran it at 540 speed it it did what I wanted it to do. I don't know the brand or make of it.
Exactly - you want that thing humming like it's going to explode.
Otherwise you're going to be miserable - cleaning constant clogs at the base.
These things rely very heavily upon the fan being able to draw everything out from the bottom.
If they're not going fast enough - they simply clog up - as they get more and more full, the worse it gets until it stops working altogether.
You'll just keep repeating that cycle over and over again till you pull all your hair out.
took a few more pictures last weekend of us grinding corn - friend Steve on his G - and friend Bob looking like ol man winter - who was feeding the mill covered in dust.
They do work very well off a belt, can't see any reason to change from that.

I should add that the screen size probably makes a big difference in how well it works relative to speed.
We grind whole cobs using a screen with (roughly - not sure) 3/8 to 1/2" holes. Might not clog as bad if you went with a finer screen at low rpms. And what you're grinding probably makes a difference too.
but really not sure.
And the rate at which you feed it makes a bid difference too. I imagine at 540 rpm you'd have to go real slow.

Nice pictures!
We used to grind shelled corn and roasted soybeans when the wife had pigs and chickens. One old tractor will turn up almost 800 PTO RPM on a 540 PTO, as PTO speed is at a relatively slow engine speed (1350) (And I put a later model governor spring on to get the higher top speed)
We weren't looking for a fine grind, and it worked well. I think we used a 3/8" screen mostly.
We did get the finest screen we could find and grind our wheat for bread flour. But we kept getting grit. I finally figured out it was rust particles, probably mostly from the dust collector/bagger.
PTO works good if you don't have a handy spot to anchor the hammermill down!

Family had a hammermill powered by a Farmall M pulley and belt. Got tired of hooking up the M and belt every time we needed it, so we got an old Olds Rocket 88 V8 engine and trans, built a frame out of 8X10s and hooked it up permanently. Pulled the pulley off the mill, made a short driveshaft and hooked them up. Worked like a charm.

That is fine grind for cob corn. For feeding cattle, either side of an inch size screen works well around here. Breaks up the cob and cracks the kernels, without making too much flour powder.
I ran a fine screen once, it sure took long to do that. Dad would use the fine screen for hogs or the chickens, I was too small to be aware of the details for that.
Around here everyone went to mixer mills over a half century ago, don't see independent hammer mill any more.
Nice pics.

At one time there were some kits sold to hook up a PTO shaft with a car tire on it with the face of the tire against the original pulley on the hammermill. Those probably aren't made anymore, but if you got lucky you might find a used one, or maybe find someone that could make one for you.

Case had a pto hammer mill in the early 50s for their early Eagle Hitch (3pt) tractors. I have been looking for one for years to go with my VAC.
Absolutely right, and the only reason we don't go with a larger screen is simply because we haven't found one yet. We're looking.
It's finer than we'd like, but not horrible.
Another friend has a large corn operation - he usually has an acre or two leftover he lets us pick - it just costs us gas to pull a picker, so we don't mind that the grinding isn't all that efficient (or too efficient depending on how you look at it).
Used for chicken feed, also mixed in with goat feed in the winter, and for finishing half a dozen herefords. Gets mixed into feed for a few belgians too. A few pigs from time to time.
A little goes a long way for us. It's mostly filler to lower feed costs. Kind of 'icing on the cake'. Plus it's gives us something to do to keep us out of trouble on days where there's not much else that can be done.

I would be interested if you found one, Thanks
You may be right Leroy! but I took it to be homemade! They used a 1 1/4" shaft, and a couple of good pillow block bearings, and those two pulleys cost some! My biggest screen is 5/16" and smallest is 1/8". I really need a 3/4" screen to keep from making powder out of shelled corn. I mounted a rear axle off a front wheel drive dodge mini van, under mine and a tongue with a crank up trailer jack on it. It sits solid when useing it.
These guys will make screens to size. They were very
reasonably priced, but its been over 10 yrs. since
I've ordered from them.
