Hi, sorry for english only this forum I think can help.
My 580f is locked in 1st gear, impossible to move the stick.
the high low stick works normal. everything works normal, and I can use the tractor. Exept wery slow speed..
Can someone tell me what to do, or what can be wrong?

I also need a workshop manual for this tractor if anyone has one that I can download?

Mon 580 F est bloqué en première vitesse, le mode lente/rapide est opérationnel. Que faire?
