Farmall Cub

This is a HubCity PTO gear box with an additional cast spacer instead of the normally seen stand off plate.

This LowBoy was once a "modified" version although the tie rods are the only survivors as all the other parts had been removed.


The same LowBoy did have a temp gauge nicely installed in the lower radiator neck. Not sure if it was original but it had been there a long time.

This Cub a a slew of clutch/PTO issues, none of them were being helped by the trash that was wrapped around the fingers! It was about the time I was taking this pic that Roys trained attack YellowJacket got me!!

The unit bolts to the spacer, the spacer mounts directly to the pto mounting plate, replacing some of the shorter bolts with longer through bolts.

Just a note on the Hub City unit with cast iron adapter. This is model # 02-20-01302-022, the same as #02-20-01101-022 except with the rigid cast iron mounting. For use on a 154 Lo-Boy. Changes direction of pto and reduces speed from approx. 1600 rpm to about 575 rpm.

There is also a model #02-20-1401-022 that has a cast iron adapter and is a direction changer only and is for use on Cub Cadet series tractors with standard P.T.O. speed of approx. 515 rpm. reverses pto at 1:1 ratio.

User should check to see if the pictured unit is a "reducer" or "direction" changer only. Thanks, Steve K. (formerly, Hub City Dist. Mgr.)

Steve, does that mean it will not bolt to a regular Cub? Or would it be of any use on a regular Cub.

This unit is a reducer/direction changer and has the #02-20-01302-022

Steve, if it mounts to a 154, I assume it will bolt to any of the cub transmission housings. Is this correct? I have it outside, and if I was not so tired, I would go out and mount it to see.

Maybe tomorrow.

I checked it while we were at DSCF. It is a speed reducer.

Barnyard and Dale, (thanks Jim for checking the unit) I don't know if the unit will bolt up to the standard Cub vs. the 154 LoBoy. That's just what the catalog calls out. I would believe the unit in question will fit the standard Cub with the standard steel adapter instead of the cast adapter. Maybe the cast adapter moves some "angle of the dangle"(engineering talk) to accomodate the Model 154 tractor? Is the 154 pto mounting different than a standard Cub?
I'll try to post the page from the catalog tomorrow if I have some time. It just gives the specs. and is not a drawing.
I believe Hub City only made the main reducer the same for the Cub, Cadet and Kubota applications and fitted the reducer to the different tractors via the different adapters. Thanks, Steve K.

I believe so as well, the basic gear box was the same for all applications. The differences were the mounting bracket and the gears. The numbered Lo-Boy PTO comes out through a flat steel plate so the formed steel bracket for a Farmall couldn't be used, thus the cast adapter. I have seen an adapter that looks like this one used to mount one of the units on an offset Lo-Boy. I have assumed the cast adapters were all the same, but don't know that as an absolute. Dale should be able to test fit his on a tractor to confirm it.

The 154 PTO does not go through the transmission case, but is mounted on top of the case by the steel plate Jim speaks of.

Looks like Jim and Paul have it covered! Thanks, Steve K.

It does mount up perfectly on an F-Cub. This is my 49.

In the first picture, the cast spacer would get bolted to the pto plate with 5 bolts(2 each side, 1 in bottom)

the second is it sitting in place

the 3rd is how it would be positioned for use

Here is the catalog page from the Old Hub City Catalog. Hope it is useful to you.
Dale, good job with the pictures of the mounting. Can you tell why Hub City says for a "154"? Would the cast iron mounting be special for it? I would think the steel plate version would have been way cheaper to manufacture than the cast part and would wonder why they would make the cast part if the steel would suffice?? Steve K.

Steve, I do not have a 154 but I have a 184 here I can look at. It is my belief(IMHO) that the original plate mount for a cub was fine and adequate. When the 154 came out, was a different mount required for use with the 3 point hitch?

In which case a heavier more stable, or different mount was required. By '68 metal was more readily available and more cost effective to make 1 mount for all cubs rather than 1 for the offset tractors and another for the # lowboys?

Just my speculation.

Dale

If the gearbox was to be used on the numbered series tractors, a different mount was required because the PTO setups on each tractor (F-Cub and Numbered) is completely different. If you look where it refers to the 154 in the sheet, just a few lines after this it speaks of Cadets. Then the next model refers to cadets only even though the cast adapter is still used. I don't believe it would have anything to do with metal availability.
The more simple answer from looking over the sheet that Steve posted is that in the later years, this one adapter could be used for F-Cubs, Lowboys and Cadets.

Edit: ...looks as if a choice was available between the cast spacer and the steel bracket. As a F-Cub owner this would give you the option of either one depending on how often the gearbox was to be used. If were permanent, I'd want the cast spacer for durability. If were to only be a few times a year, I'd take the steel bracket because it's easier to get on and off.

I did look at the 184, and I believe you are correct on all counts
