Fuller 9 speed shift pattern

Spot on regarding the 13 speed Spardo. Most 9 speeds I drove had right top and right bottom as 3/4 and 7/8, although I do recall driving a 1980 Foden with the pattern you state.

Now then, there will also be a “sneaky gear” whereby you can shift into the crawler gear in high range. Used to be very helpful in the days when your 250 ■■■■■■■ just wouldnt take the fourth to fith change when struggling to haul 38t up a steep climb.
