Ron B in ohio 07-28-2012 05:36:04 66.102.63.244 Report to Moderator	I bought a JD 10A Hammermill, PTO driven, the issue is proper rotation. The wear on the teeth in the mill suggests that the hammerteeth force the feed down into the mill as it is fed into the mill. I am powering it with a Ford 801, PTO rotation clockwise as you look at it (I don"t know of any other rotation for a tactor??). This makes the mill run so it tries to throw the feed up over the top of the mill. I have not tried to run feed through it yet so I don"t know if it works or not the way it is. ????

We also had one for years when I was a kid. Looking at the pulley the shaft would spin CCW This would also spin it correctly for the blower. It would lift up on the material as it entered because the way it is designed it blow out the door if it was to grind downward. And the chute was on the right as you looked at the pulley. parts book JD10a   [Reply]  [No Email]

The machine fan does blow "out" like it is supposed to with some force and also rotates CCW as you face the PTO pullys, however the teeth of the hammermill are coming "up" against the feed as it enters the mill. I will look more closely at it, perhaps it does have an aftermarket PTO adaptor on it. It worked for the previous owner fine, just spit grain at him a little(as stated by tractor 300). Now then, does anyone know a quick way to build a set of gears to get it to run clockwise??   [Reply]  [No Email]

That would account for the hammers to come "upward" as the grain is fed into the mill. #2--If the concave is rotating incorrectly, but the blower is functioning as it should---then maybe the fan belt is twisted one-half turn, when it wasn't intended to work that way. Interesting circumstances !!!   [Reply]  [No Email]

Turned the same way as the PTO,hammers came up instead of down,fed on the left as you're standing behind it instead of the right like all grinder mixers. I worked,I used it for a lot of years,I just always knew it seemed odd that it ran the way it did. Just seemed like whoever designed the PTO adapter didn't really think it through.   [Reply]  [No Email]

It looked to me like it ran the wrong way,but the blower on the back of it worked and you'd have thought if it wasn't blowing the feed out that would indicate it was running the wrong way. Don't know,just know it worked.   [Reply]  [No Email]

Rotation has the hammers forcing to feed down against the shear bar that holds the screen in place iirc. CCW facing the main shaft where the drive pulley(s)is/are.   [Reply]  [No Email]

Year's ago I had a 10A with an aftermarket PTO setup and it worked proper with grain going down to screen. Good mill, ground a lot of feed with it, more than I care to remember. Check the rotation again, if it is throwing the grain up and around it would probably be spitting part of it back out the grain chute.   [Reply]  [No Email]

This SHOULD be the correct rotation. The rotation should be such that as the grain enters the mill, the hammers force the grain downward towards the screen.   [Reply]  [No Email]
