I just aquired a B6100E, 2 wheel drive, 3 sped manual tranny, with a 3 speed PTO, which I have listed in the classified for sale. I am not familiar with the 3 spd pto. What are the speeds for the PTO and any other things I might want to know before selling this tractor? I already have a Yanmar 185 and a Ford 4000, both great, but both are hydros, so I really don't need the Kubota-or do I?
