Allis Chalmers rake model/serial tags

We have two old AC rakes.

I've never really cared what the model/serial numbers were, because they are visibly and obviously identical; so one is parts, one is workable.

I recently, out of curiosity, tried to find the part number/serial tag with no luck.

I don't have a picture (yet)... but they are rollabar style.

The rear axle between the rear tires has a sprocket, which drives a chain... which goes to a sprocket at the end of a stub shaft, which transmits power to the gear box attached to the left hub of the rollabar basket. (kind of convoluted...when you compare to the NH style, where the stub shaft connects to the end of the axle... but whatever...)

The rollabar basket is suspended by cables, which go up to a threaded crank on the top/front of the chassis.

No dolly wheels... they have (or had) a little jack and mount directly to the tractor drawbar (much like a New Idea 402... which we also have)

Any guess what this model is or where I might find the tag?
 

Our rakes have this kind of suspension

(quoted from post at 12:29:35 03/29/23) I like the bulldog jack. NH 55 uses the
most cockamanie jack I ever saw. I don't
know how its even supposed to work.

(chuckling)... Yeah... some of these jack setups on these old rakes are such a pain that I just have a big round of firewood that I set under it. I'm still strong enough to just lift it off and hook it to the drawbar... but I'm getting a little older... so a MacGuyvered jack is starting to look like a better idea than the stump or the original goofball mounting system.
 
If it's a similar style to the one in the picture, probably a 77G or 78G (or some variation of the 77/78 models). That's what it sounds like to me. The parts manual for
them applied to all 77/78 models. The 77 had a straight rear axle, the 78 was crooked.

There was also the #7 and it's predecessor (no model number, just called the 'PTO Rake/Tedder') that were PTO driven had a long basket and a gearbox/dual input
(depending on which one) that could run it at different speeds and in reverse to act as a tedder. Not what you have, but they were pretty neat.

Agco took down all these parts manuals from their online library unfortunately, but if you google them, lots of people are selling original or reproduction parts &
operator manuals for them. I know you can still get the teeth from AI and other aftermarket suppliers (any dealer can order from AI). Depending on how the rake was
ordered, it might have a few different teeth options. See link below. I also think the rubber-mounted teeth that fit most Massey/NH/Deere rakes also fit them.

I've learned over the years, why rakes went to the crooked rear axle.

Our New Idea 402 has a straight rear axle and a belt drive. Growing up, I was always around NH rakes (256, 56, etc) with the crooked axles.

When we first started using the New Idea, I thought the straight axle was a better design. No universal joints required, like the NH rakes had. HOWEVER... to have a straight axle, one of the backbones of the rake needs to be 18" to 24" longer. While raking a particulary bumpy field, the long backbone on our NI 402 snapped in half. I looked at it and noticed that it had already been welded once.


Fortunately, I was able to literally MacGuyver a repair with two pieces of angle iron, two big U-bolts and 14AWG electric fence wire (seriously), in about 45 minutes that has lasted six years since... :)
 

Here is a stock photo of a NI402 with the straight axle like we have off of the internet... marked up to show the long spine... and where ours broke.

Due to the drag of the wheel, where the weight of the basket is suspended and that long spine... I'm not surprised that it broke where it did... also not surprised that the straight axle rakes were replaced with crooked axle rakes.

I never thought about the extended frame having less stress on it, but I see that it would. The crooked rear axles certainly follow uneven ground a lot better. Those belt-
drive NI ones like you have are also good rakes. We had a couple of the reversible Allis rakes/tedders that I mentioned in my last post. A neighbour liked the idea, so he
had a spare belt wrapped around his New Idea axle at all times that was the right length to flip around and run it in reverse to tedd. Only took a couple minutes to flip.
Didn't work quite as well as the Allis ones because the rake tires ran over the tedded hay and you couldn't angle the teeth as far back as the Allis, but still did a
pretty decent job nonetheless.
 
Till I bought the wheel rakes I never used a rake on rubber tires. Always used the old Deere and IH ones with 4 steel wheels on them. Still have all of them yet and still go pull one out of the bush to use sometimes.
