Let's no.80 plates

I have a "borrowed" letz 80 that I run wheat thru for my hogs. The burr plates need help --well worn with a couple cracks. Any suggestions? Rebuild/ replace? I am not in the Mid-West with barns full of old equipment sitting around the neighborhood.

I do have a really nice hammer mill sitting in reserve, but not confident the MF 135 would run it. Plus I well remember the noise and dust generated from when I was a kid decades ago

**** "Let's". Dang auto fill....... *****
 
You could vary the rpm of the hammer mill to minimize the dust and/or change the screen size being used. That also changes the product to something maybe more desireable.
 
What size mill? would have to be a very big one for the MF 135 not to be able to run it. You have either a 35 PTO HP engine (Gas) or 39 (deisel). Ran a 10" mill with 20 MAX PTO HP on B Deere.
 
Your tractor will run your hammermill just fine. You will just have to adjust the feeding rate for your power. If you are feeding wheat to hogs be aware if you feed it straight your hogs will get constipated badly if you don't have some corn or other grain to mix with it. Mike
 
You never change The RPM on a hammer mill from factory spects as slowing them down will not let the blower part work and will plug them up. You change feed rate by slowing it down if you are low on power. And change screen size if making too much dust.

I hauled the mill from barn to shop, tore it partially apart and blew it out good. Spins very freely by hand. 3 out of the 4 cutting edges are factory sharp so it will outlast me at the rate I will use it. It is a 10" so we should be good as long as I get the drive pulley ratios right. The MF135 is a......deluxe? 3 cylinder, exhaust on driver left, square fenders, hi-lo.

Thanks I will approach it that way - match feeding rate to a fixed power setting.

It's a good thing my critters have not read the book! :)
We are a long way from the Corn Belt - soft white winter wheat is the local feed grain of choice -- can be subbed 1:1 for corn. Some locally went better than 4 ton
 
Your owners manual should give a RPM setting for correct pully speed and with that it should automaticaly come out to correct speed on mill. I have never tried to figure out feet per mimute on my tractors. I have Fords, 9N & 2N but never had them on mill but on buzz saw and on that you can tell correct speed from sound. Whe using the mill we either used a 46 or 49 John Deere B at normal PTO speed. Buzz saw normally does not need to be run that fast.
 
Soft red winter wheat you cannot do that with and that is what the poster was talking about. Never seen white wheat.
 
If you're just talking about a straight hammer mill vs an actual grinder mixer... I think you'll be fine running a 10" mill. Just run the tractor wide open and adjust the feed rate to lug her down to where you're comfortable.
Normally when I think of hammer mill... I'm talking a NH grinder mixer. Mine has an 18" mill. It comes with a class 6 power shaft meaning it will take 110 hp... and to get much done with it... it wants that power. You can run it with 60 but you don't get a whole lot done. Mine with sufficient power will hammer 6-8 ton per hour...
Also, adjust the screen size for what you're trying to make. I think you're going to want a 1/4" screen for wheat. Just run a bit through at what you deem a normal feeding rate and see how much pass through you get that's not cracked. You might be able to run a 5/16" screen if it's larger seed and you're getting the desired amount of processing. That will take considerably less power than forcing it all through the small screen...

I have seen hard red winter, hard white spring, hard red spring, soft white winter - never heard of soft red winter ! :?

My in laws are driving to Berlin.....could they find me some there?

Soft white winter is a big export out of the PNW. It is a cracker/pasta wheat.
 

Yes straight mill -- no mixer.

One reason I would prefer to get the burr mill repaired is that it is smaller capacity. A typical daily feed batch would be 3 or 4 buckets. I can batch mix my grain, SBM, mineral pack and be done in a few minutes. When we used to mill grain in 60's and 70's we had overhead grain bins with wood chutes down to the mill and overhead bins for bulk storage of the chop. Moormans Concentrate was metered in continuous flow. I don't need the larger capacity now....
