I think a Allis Chalmers b112 variable bevel gear box Ebay #220715649290 is the size your looking for?
After doing a search on small tractor net I found that this is not what they posted but a standard Bevel gear box, disregard sorry.

That is probably close, unfortunately, that appears to be a transaxle. So far, the only thing I have found that appears it might work is still the aftermarket Harley Davidson type, stand alone, motorcycle transmissions. I found an Ultima 5 speed motorcycle transmission for $529.95. I would assume it would hold up under a 20 horse Kohler turning a cvt transmission. Remember, I want to use the cvt that came with the max. I probably wouldn't even shift on the fly, I would probably pick a gear and drive it, if I needed a lower or higher gear I would stop and select it. Somewhat like you would on a sidexside or 4x4 atv. I'm still looking though. Monday I'm going to check with the Garden tractor pullers and see if they have something.
Why not build your one?
Take a look at this.http://www.thepixelpump.com/widdersh.../Gearbox-1.jpg
It's simple and you can make it any speed ratio you want.
I found it hear, Widdershins Way - DIY 2-speed Transmission
You can build one inside a box and give it an oil bath even. It would be a lot cheaper than a commercial unit.
I'm still looking for ya,
Now that would work... instead of driving TO the T-20 you would drive this FROM the T-20, and you could build it as small as the sprockets would allow!
Yup it's stupidly simple and it will work on ether end of the T20. you can even go with double roller chain and sprocket's to beef it up.
The problem with small tractor transmissions is that they almost never have a 1:1 ratio, I don't think one from a motorcycle will either but I can be wrong.
After thinking about this it would be better to drive TO the T-20, otherwise you would have to have one for each side...right?
FREQ42,That is really cool. Exceptionally simple. RI should look at this and put it in production. Harley Davidson type motorcycle transmissions are either 1:1 or a small overdrive around .87:1 in high. 1st gear is 2.94:1 or 3.24:1. I wonder how much it would cost to have a machine shop build this?
Brushcutter, you would have to still run it through the T20 for steering and braking.
Whipper would be the one to ask about building a 2-speed transmission like this one.
I like the guys transmission, thoughts, and even execution. I'm left scratching my head as to why anyone would spend so much time on such a small and cheap go-cart.
l like to buy stuff and no I don't do payments!

Yes this can be built by any one with simple tools.
It can even be built using the gears out of one of those parted out tyranny's on ebay by only using the shafts and a couple of the gears I would imagine.
Going back to the basics is what this guy did and it works, Hear we're thinking of this big complicated setup using different gearboxes and transfer-cases when alls we needed was to go back to the basics. I admit I to was not thinking about the basics ether for this project till I stumbled across this on a welders forum I belong to.
As for RI not using it in there production?
