I have a Kubota M8580 and I dont have any 6th speed at all. I was scrapeing with a box blade in 2nd or 3rd and all of a sudden it stopped moving. Now it moves but dont have the 6th gear. Any suggestions on where to start looking?

Yikes, about only one option, in the transmission!
Sounds like you've broken a gear or more.

Yep, I agree with NIW. Does the transmission fluid have that expensive metallic look? I would stop using/driving to limit the damage.

I guess I drove the tractor some more and found out that the tractor does drive in 6th gear in the opt. creep range. But has hard time moving in the L or H range. Ill have to make sure those pressures are correct like other post said.

I guess I checked the IC shuttle clutch operating pressure and had around that 270 psi, so Im leading towards I have a bad clutch?
