Whats the ground speed of a 190 xt without a Powerdirector say in 2 nd gear ? Is it the same as 2 nd gear low side ?

If there is no Power Director clutch assembly inside the tractor, someone has made a coupler to connect the transmission input shaft to the torque tube gears. So, depending on what they did/made, it could be direct drive (HIGH) or under drive (LOW).

would be more "efficient" but only slightly and without the motor to turn it it wouldnt be any better

haha, yes as the Dr. said High is direct and low is underdrive, so 8th would be 8th not 7th in direct. Turning a strait shaft will be easier than 2 geared together and my motor comment was referring to not enough motor as in pulling in 8th vs 7th.

takes a lot of power to pull direct! Hence a lot of motor! lol! Some tractors just cannot hack direct, so the option of running it in "7th" gear will help it pull better. Speed selection in pulling is usually dictated by the available hp!
