Early Allis B, Hand Lift

I was wondering if anyone might have a picture available of the rockshaft used on a early handlift model B? I have a 1939 model that has the cultivator frame and lift handle, but does not have the rear lift accessories. I have an Athens Plow that I'd like to hook the B up to, but I'm not sure what I am missing. Any help? Thanks, Tim

Unfortunately I don't have this mounted on a tractor, but you should have two bearing brackets bolted under the seat that hold the rockshaft like below. This is the early hydraulic lift rockshaft with some "add-ons" so don't pay attention to the shaft itself. The right hand hand lift bearing bracket is slightly different from below and will have a little L-shaped keeper that prevents the shaft from rotating - it goes through a hole in the shaft and fits into the bracket.

Now, for the hand lift plow, the rockshaft is just a solid shaft with nothing welded to it. The plow lift rotates around the shaft. It's leaning up from the back in this picture, in front of the utility pole:

Hopefully your setup looks somewhat like mine. Otherwise I'm probably just confusing you. Sorry that I don't have a picture of the brackets and rockshaft on the tractor. Feel free to ask if you need clarification because it's kind of confusing without that picture. I do have a manual for the early B hand lift plow but it's at home and I'm at school.

Athens disc plow is a whole different setup I believe. Perhaps Bill P or Brett Phillips could enlighten you, they are two guys I know have the disc plow setups...

and...

My dad always told me the disk plows pulled harder than moldboard types any truth to that?

Not sure about the comparison in pulling. My grandad used the disk plow behind a CA, but later replaced it with a bottom plow. He had both the wide "drawbar" used by the C and CA and the narrow "drawbar" used by the B. He didn't have a B model tractor when I was around, but as I understand it at some point there was one on the farm. Knowing that the B was rated for a one bottom plow I was worried about its ability to pull the two disk plow. She did good though. She'd turn all the topsoil over, 6 to 8 inches, and even go down into the next layer of earth, red gumbo clay. I set the depth of the plow to stay out of the red clay.

Here are some pics of the hydraulic Athens rockshaft set up, sorry I do not have a hand lift pic.

Ryan's picture shows the correct rockshaft. The hand lift has a flat link that attaches to the rockshaft about where the hydraulic cylinder would (just to the left of the depth stop crank in his second pic). The rockshaft is actually the same as the one used for the moldboard plow, but there is an arm that bolts to it for the center lift link to attach to. I have 26" discs on my Athens 2-disc plow, and it can be a handful for my '43 C if the ground is really tight or full of sumac stumps as it was at one plow day I participated in. For the most part though, it is a good match and is a real crowd pleaser at plow days and shows.

Neat plow, twelliot! I wish you luck in finding the right rockshaft... somebody on here has to know. I'll do some searching tonight and see if I can dredge any old pictures up.

Thanks Glenn and Ken. I was lucky enough to find an old manual for this at OPOP this past summer. This plow has a modified trunnion that they only made for a short period of time, I believe. I think the only things I'm missing are the plow drawbar brackets and the L-shaped angle iron that bolts underneath the seat. Hopefully the brackets from my later style drawbar will work, and I think I can make the angle iron piece. Should be a good showpiece and a blast at plow days.

Not to be a wet blanket, but the later brackets for the "rectangular" drawbar won't work... The offsets are wrong. You need a set that looks like the one on the left in the below picture. It is off the very same version of the plow you have.

So Glenn,

The part on the left, where on the rock shaft, or lift shaft as it is referenced in the Athens manual, would the part attach? Is it at the area of #3 on the attached illustration?

Hmmm... can't say for absolute certain, but if I were mounting up a WOODS belly-mower, or a belly-blade of some type, or a simple swing-down type cultivator toolbar, that'd be just the thing...

Ken, those are for the early plow. At some point they went to a round headed pin, rather than the "L" shaped pin, and lost the little clip, as it was no longer needed. I got some of them too, in my parts piles. Don't have enough pieces to get you a complete very early B plow and still have one for me.... Glenn

Yeah, sorry. That would be my fault for getting off-topic. I'll start another thread, especially since it's obvious that the hand lift is different for AC and Athens plows.

Hmmm... is this the 'correct' setup for a '38 hand-start B? If so, and someone else (like Georgia Tim) hasn't already approached you for it, I would certainly negotiate a deal to take it off your hands...

The rockshaft from Minn is off a C.
