Need help to identify this gearbox? 3-speed something

Errrr.... 400 series maybe? H shift pattern of some kind. Depends on how much power you throw at it

Ah here we go... 600 series. Oil filled. This PFD is for a 600-601.

Are we making a mud mower or something?

I had one of em in my old monster mower and it was ran with 28in mudzillas and was pretty strong

We used to run 600 series trannys like those... they worked ok until we started upping the HP to the 16 - 20 range... with a 20 HP, you'll likely break things.

ok thank you, might choose live axle then, ugg idk.  

They are fairly beefy, but a spinning gear will weld itself to the shaft at higher horsepower and input rpm. With a 4/3 ratio, and 18.5 tires, top speed was around 35mph.

If it was geared to 25 or less, it would last forever.

if its a h-pattern shift you could build a mini-car, like a mustang or something
