185 tranny swap

Postby TTrebesch » Sun Dec 11, 2016 8:53 pm

I have a 185 that I would like to swap the transaxle out with one from a farmall cub. Just wondering if it would fit without any issues

Please describe the word "transaxle" further. Typically, this would include the transmission & the axle. Are you including the final drives with this?

A couple of items come to mind... A Farmall Cub drives its PTO through the transmission. A 185 has a live PTO and is separate from the transmission. The PTO would have to be removed from the Cub transmission.
2) The final drives would have to be rotated 90 degrees to make it a loboy. I don't think the brake rods would line up with the access hole. Also, the 185 is not an offset cub, so some spacer changes and shaft lengths would have to be modified.

I will call it the transdifferential then I don't plan on using the final drives from the cub but I do want to use the pto that is the reason why for the swap.

IMHO that might be one of those things if given enough time and money invested could be made to work but not worth the effort and expense. There's a lot better and less expensive ways to get a PTO.

Although I've never tried it, I don't know of any specific reason the basic PTO unit wouldn't go into a 184 transmission. Problems I can think of:
- 184 main shaft may not be drilled/splined for PTO pilot bushing and shift coupling.
- need to figure out how to engage it as the original lever would be out of reach
- you loose the original filler/lever plug.
Swapping in a Farmall transmission would not help any of these problems as you would need to reuse the 184 shaft etc.

You probably need to back up a step and look again at why you want to do it.

What exactly is the motivation to swap the tranny? A cub PTO is not live. Push in the clutch and the PTO stops. Since a 185 is a very capable mowing machine, it seems like you would be losing the benefit of that live PTO. Is your PTO Clutch dead? HamiltonBobs has a PTO Clutch for $400.

Why swap the transmission? Is your transmission having an issue and requiring a rebuild?

Numbered Cubs are/were normally light duty tractors - lawn mowers. Very little wear in the transmission/differential after years of use.

Fix the 185's PTO, expensive, depending on parts needed.

Numbered Cubs' PTO can be engaged with the tractor stopped. Standard Cub, you engage the PTO, then start the tractor moving to apply power to the mower or other implement.
I have an excuse. CRS.
