Hi guys, I was wondering if anyone has put a 2 speed pto on a D19 or a 1000 pto on a D19 off a 190 or 200? Is this something that might even be possible? Thanks!

Yes, kind of possible. Never from the factory. BUT, the results would be approx 270/540 RPM because you have no speed up gearing from under the fuel tank thru the torque housing gears. That's where a mighty One-Ninety is different.

Looks like shafts and gears changed alot in the center housing of a 190 to speed up the pto drive shaft. Neat to know that the 2 speed part would work but no one needs a underdrive pto. Lol Thanks!
