Enlighten me, please!

After days of searching through my books, and in the archives here at this forum, as well as the parts diagrams on the CaseIH site, I cannot find anything that would tell me what this is. It is located in the place of the belt pully drive on my 46 H. Perhaps I'm just missing something, but I cannot figure it out for the life of me.

I've been going through this H a little at a time over the past year or so and have been able to rework all the problems it had with a combination of sevice manuals and these forums. This is the first time I've actually ran into a road block so to speak. Thanks fo any input you can give me.

Could it be some sort of creeper drive?

It's probably aftermarket since you can't find it in the IH books.

Anything cast into it as far as words or numbers? (Please don't say it says "Heisler Creeper Drive" or something blatantly obvious on it!!!)

My guess is it's a creeper drive, driven off the same gear as the belt pulley, but driving agains the speed gear that an Elwood front wheel assist would get its power from. I would expect it to operate like this:

1. put tractor in neutral
2. pull lever on gearbox back
3. let out clutch.

Tractor should move at a snail's pace.

I'm with mkirsch. Can't say anything definitively, but I suspect either an over- or an under-drive.

I double checked for stampings and found none. I can see it being a drive gear as described due to the fact I can hear something engaging inside when I move the lever. It is also not attached to anything such as hydraulics, etc.

I've saved the pictures and blown them up so i could see it a little better, but I've never seen anything like it. I would gues that the others are right--- it's some kind of aftermarket creeper gear set-up. Seems to me that I saw an H at a show that had been modified to run a vegetable harvester--- beets maybe--- that had a different-looking creeper gear attached at the same spot.

Now, to poke a little fun at a fellow I respect GREATLY on here--- You didn't buy this H from a fellow named Wardner did you?

Yeeowch! LOL!

I dont know what its doing on your Farmall but thats a sidehill starter adapter,special order for the Tri-Directional Essex! Hoss

Have heard that you can run up to 8 hours pulling heavy load using starter power alone, saves a lot on fuel.

If you really want to know, take it off and photo the process of lifting it up. Show the underside, and we will guess some more. Nice mystery. Jim

Here are some bigger pictures. I like this stuff but I don't know what it is. I'll study it some more.

I still don't know what it is. If I owned it, I would remove the six bolts and take a peek.

There appears to be a yoke that moves a sliding gear. This would be similar to a belt pulley gear box and cotton picker PTO. The gear has to be small in diameter (or offset to the side) and its center must be below the top of the rear frame cover. That would be unlike a BP gear box. It would also mean that it rotates rapidly.

It probably meshes with the BP driving gear on the clutch shaft. Either that or the fourth gear on the transmission mainshaft similar to an Elwood transfer case. But I don't think the fourth gear would be close enough.

The most unusual thing is the lack of a power shaft from the casting. That bullet shaped protrusion is also a mystery. Why not remove it and send us another picture.

Farmboy,

Thanks for the recognition.

I am a master of all things H... :roll: Ok, seriously, I've been researching H's for a few years, and I've never seen anything like it. Creeper gear sounds like a plausable answer, since there is nothing protruding that actually does anything.

I agree that you should crack it open and show us what's inside.

What happens when you move the lever? Tracter moves faster/slower in a gear?

I'm guessing that the dome shaped protrusion contains a stiff detent spring. I don't have a clue as to what it might be for, but you MIGHT want to use caution removing the dome shaped cover.

Yeah, the detent spring makes sense but why so
big?

The width of the raised part of the casting (left to right as installed) would
seem to indicate two small gears on two separate
shafts. That would be necessary if one of the
gears was meshed to the 4th/5th slider. Otherwise
the tractor would have four gears in reverse and only 5th and reverse going forward.

FWIW, the picture below is how the Elwood transfer
case extracted power from the 4th/5th slider on
the large framed tractor. On the H being discussed it would be
reversed. Power would come off the BP gear or constant mesh gear with
one gear and it would be sent over to the other side of the
tractor. At that point, a wide sliding gear would
mesh with the 4th/5th gear on the mainshaft.

Which attachment gear slides is unknown but the
other gear would be in constant mesh and probably
noisy.

I have been thinking about doing something similar
to a W-9. But the method would be totally
different. I was thinking about running two
countershafts in the transmission. I think Oliver
did that on their industrials and maybe on the
rowcrops as well.

How about a road test?

1. With the motor not running, shift the attachment lever.

2. Start tractor with clutch disengaged.

3. Select 1st gear.

4. Slowly engage clutch.

5. If tractor stalls, disengage the attachment lever and return to square one. Report findings. Thanks.

Hey guys.
Thanks for all the great input on this. I've been working my tail off, and just now have had time to respond. At my first available moment i will for sure do the test suggested.
I have been afraid until now to even mess with it while the tractor is running for fear of using it improperly and potentially breaking something. Never hurts to ask!!
Once again thank you all for your input and suggestions and hope to be able to work on this Saturday. I will post my findings.

I think it may be part of a gear drive system that mixes batter for those giant cakes that Neck-ed gurls used to jump out of in the immediate postwar era of the late 40's/early 50's at corporate board meetings. If that proves to be correct (and I'm sure it is) then Wardner will probably want to buy it from you.....
HAW-HAW! (Just kidding, Wardner.)

You nailed it Red Mist. I would like to own it. But it would be helpful if I knew what it did before sending money and/or a replacement belt pulley gearbox.

(quoted from post at 21:56:52 11/05/09) Otherwise
the tractor would have four gears in reverse and only 5th and reverse going forward.

Don't know what I was thinking when I wrote that. Yes, the attachment needs two gears to allow forward movement. However, the OEM gear shifter cannot select any gear. If that is done, it will lock up the transmission and stall the tractor when the attachment is used.

So the road test should be as follows:

1. Move the attachment lever to rear position,

2. Start tractor with clutch disengaged.

3. Select neutral on tractor gearshift.

4. Engage clutch. Tractor should move forward and most likely at a slower speed than first gear.
