When you say put it in 1st or 2nd gear is that the main transmission for the tractor or does the pto have 4 different speeds available? The only reason I ask is because as far as I know tractors that size usually have 1 speed for the rear that runs at 540 and one for like a mid mount mower that runs at 1000. One runs out the back and the other hangs down under the tractor and points forward and when you put it in gear it turns the appropriate shaft. Being that you said the tractor is a gray market one it might be different but I would think it should just be put it in and out of gear and set your ground speed with the main transmission. Stewart
Your tractor has a 4spd PTO?
I till in low first gear for my ground speed, this tractor has a 4 speed PTO, 1st gear is 540, 2nd is around 700, 3rd is around 900 and 4th gear is around 1100 (If I remember right). A friend has a RPM tester and he checked the speed of each gear when I got this tractor probably close to 5 years ago. The PTO turns the right direction, this tractor also does not have a mid PTO.
I love this tractor because it's a grey market, it has things that the US models don't have like a 4 speed PTO, I also think it is a lot heavier built then the US models.
I added the only 2 pictures I have of the shifters I could find, the shifter on the right is for the transmission and the one of the left is PTO. Those are old pictures I found of when I had a plugged vent and it was leaking oil out the shifter.
