Thanks for your replies previously. Got another one on the plow. The one I'm looking at apears to be a snap coupler (tow bar burried) but I did find the lift arms, and they're proper.

I'm wondering about the tail wheel set-up. The one I found has a steerable rear wheel (connected to the front with a tie rod) and another tire mounted to the side at the rear to controll the depth. Is this a newer plow? Will it work on a WD45? I'm quite sure it'll pull it, but the steering system is making me wonder if the couplers will work. Anyone have a guess as to what model it is, and possible age?

Scooter Dad and I used to plow with an old Athens plow. It was a disc plow though. It was set up on a WD and painted AC orange. As I remember it looked pretty much like you described and it did pivot behind the tractor. The tractor did not have a snap coupler bell on it this plow hooked on where the drawbar pin wich had to be longer, but it could have been made to fit a snap coupler as I have seen plows the same as this one with Snap coupler. If I am not mistaken AC either had an agreement with Athens Plow Co. or bought them out I am not sure.

I have to disagree with the previous comments. I have a plow just as you describe and it is semi-mounted. It will work very nicely with a snap coupler hitch. If it is a four bottom plow, the biggest question is will the 45 pull it when it is in the ground.

There are TWO wheels. One is a gauge wheel and it is next to the last bottom and rides on the land side. The steerable wheel in the rear has a linkage to the front of the plow. This design was done when the plows got to be large. Turning problems caused the land area at the ends of the field to get bigger and bigger. In about 1961, almost all major companies came out with steerable semi-mounted plows which allowed the lands to become much smaller again. My plow is like this and it works just fine. I don't know what year my plow is but I would guess it is about 1965.

Good Luck!

Denny, do you have a way to send pictures of that plow by e-mail? Do you have a manual or know the model number? The only Allis plows I have ever seen set up as you discribe are three point hitch semi-mounted plows. There never was a snap coupler plow bigger than 5 bottoms and even the 5 bottoms I have seen are set up just as I and Ron discribed them, they don't pivot behind the tractor, they swing behind just like a mounted plow when you turn except the rear is carried on the the lifting caster wheel.

Great Denny, thanks for your input! Now, if the snap coupler didn't change (hope it didn't).

Here's the way I see it. I'm pulling a 3 bottom with a Ford 641 Workmaster (rated at 2 bottoms). With a little weight in the tires, 4 should be no problem with 45 (rated at 3 bottom w/15 more hp) I think I could get away with 5 if I wanted to really work it hard.

If it is a Semi-Mounted AC plow..a rod to steer the rear wheel won't work..!!! The plow HAS to go with the tractor....!! Maybe what you have is a Pull-type....or some model other than one designed for the WD-45... I am not sure what models they may have made for the D-17...May be one I have not seen... The "Crazy wheel" allows the plow to turn with the tractor at all times...and has a Hydrolic cylinder connected to it...to lift and lower it... ( one way hydrolic--one Hose )...

Here is a similar plow to the one I'm looking at. This one is a little newer though. The hydrolic ram is mounted closer to the plow frame (longer ram) and it has the wheel on the other side from what you can see here. It also has a tow bar on it. I did find the lift arm snap couplers, so I know that will fit, but couldn't see the end of the tow bar. Did they change that over the years?

Butch, nice rig! No, the plow I'm looking at doesn't have the front wheels, just the rear one. The wheel is facing straight forward, and the steering rod is off to the right of the wheel gear(as viewing from behind), so it's not for raising the wheel. It's actually a hydrolic raising wheel. There is a wheel on the left rear of the plow to keep the depth of the rear correct. It's got the orriginal paint and AC name on it. It also has a tag on it, but I couldn't read it unfortunately. It did, however go over the paint, so it wasn't re-painted. Also, I don't remember seeing the screw jack from the front to adjust the plow. It did have the trash boards though.

Scooter, I did a poor job of writing that post, sorry. I understand that the plow in question is not a pull typ so it won't have the front wheels like mine, but the framework and bottoms are the same on my pull type as the mounted and semi-mounted plows.The tail wheel and mounting are also very similar except the cylinder is mounted back at the tail wheel on the semi-mounted plow because it isn't needed to raise the front end of the plow like on my pull type. Allis Chalmers (to my knowledge) made three models of semi-mounted, snap-coupler plows 60-70-80 My plow is an 80 series, which is the last series of plows availible with snap-coupler hitch. In my 70-80 series parts book they show no 70 or 80 series plows with steerable tailwheels just the caster wheels. Not calling anybody anything here just curious what you have found and maybe adding to my knowledge.

Well Butch, all this kinda has me confused too I guess. I may have to just buy it and hope It'll work just to have a conversation piece. Without daily access to it, I really can't tell you much more about it. I'll try to get tere this weekend to buy it, or just look at it again to see if I can get some pics and pry the toung out of the ground. That may just answer some of my questions too. Maby I should bring the weed whacker too so I can get a better look at it.
