9N Sherman Transmission Shifting Procedure

Gary Moore I have just purchased a 9N with a Sherman Transmission. I have read some of the other discussions about it being a over/underdrive in addition to the main transmission. I wanted to find out the correct method for shifting to avoid tearing something up.

Do you shift on the move like a torque amplifier or do you need to be stopped before shifting?

Should the clutch be depressed before shifting or can you shift without using the clutch?

To clarify my understanding of some of the articles, if the lever is forward (down) this increases your forward speed and if the lever is back (up) your forward speed decreases while maintaining PTO speed?

Thanks, Gary

Bill Id Gary, Mine came with no directions either. I shift the Sherman when sitting still, press the clutch and make the shift. Forward is high and the lever pulled back is Low. If it is a Combination or Sherman Combo, half way between high and low you can pull the lever outward about 1/2 inch and pull back towards you. That will put the transmission back to the original N gears. I am not sure about the operation of the PTO since I never use mine to drive anything but a post hole digger.
