No 9-speed Fuller thread would be complete without an example of the ERF NGC ‘European’ and this example had a 9-speed 'box. Robert 
I had a B reg Leyland Constructor 2421 with a TLII and that had a Fuller 9speed box i think it was an RTX box not an RTO.The Leyland was a long wheelbase flat
As any proper driver of a 9 speed Fuller will tell you, they were all 10 speeds. 1st , 2nd , 3rd split range change into high and put gear stick into crawler, then split back into low and into 4th. This gives you a 10 speed box. I hope I haven’t upset anybody thinking they have been driving all those years and did not know the ins and outs of a 9 speed Fuller. If anybody out there has one in an old truck try it for yourself. When I was young and driving a Sed Atk 400 with a 180 Gardner and a Fuller box you needed all the gears you could find to row it along.

Forgot about the Constructor, I had one similar spec on the same job as that one except the one I had was a lwb tipper. forgot about the Marathon and Crusader I had which also had the 9 speed. Best gearbox ever in my opinion.

Yes Lance, I drove all mine like that (Sed Ak 400 and three different Foden’s) though it was especially useful on hill’s in the 400 with Gardner 201 power! 
My 3000 series Foden had the 13 speeder/Rolls-Perkins 335 combination and that was a different motor altogether.

aye the mystery gear!..its surprising the number o folk who dont know about it.
less o the old truck.its still modern technology in North America. 
Hey Robert1952, Fuller a pitty forgotten legend 
I have never known that you had to use the clutch for a 13 speed fuller,but maybe some were built so!!!
For me the best is the 13 speed because of the better spread.
But I agree that an engine with a 9 or 8 speeds can be faster. The reason, the 9 speeder has to work Always and you learn it to work. sample, you go to about 2000revs and up again from 1500, But if you have a 13/16 speeder and you do the same if you drive alone as a 9 speeds than it will perform as the 9 speeder and better with the 13/16 speeds then.
I only drove a few times a Volvo F12 with the 9 box, but as said colleagues the 360 with 12+2 is slower because of driving Always at a very small rev band.
MAN used the 9 Fuller to but some were changed to 13’s it was a easy work to do.
Here we had never a 9 speed Fuller at DAF, The Germans were frequent users of the 9 speed.
But what i don’t understand is that most had 9 speed at yours,here it was most the 13 speed.
Cheers Eric,
This Leyland Roadtrain of ours had the 9 speed Fuller box matched to the RR 300 T, A good performer , Regards Larry.

As I knew it and used it the low/crawler gear was only linked in with and used in the low range gear train not the high range.Which seems to be confirmed here. 
looks like the man in the youtube clip can’t drive a Fuller either

Neither can “CF” and he was the geezer doing the commentary

What would he know being that it was just an instruction film for drivers made by the factory that made the box 
.

By the way Bewick what was the actual ratio provided by high range crawler v 3 rd in a 9 speed box. 
i agree with lance , i drove a foden arctic with the 9 speed for years and used high crawler regularly . it was easier to keep the momentum on some hills rather than dropping the range , quicker on the up change as well .
Not a clue but it’s definitely a gear and was handy at times.as.it.saved dropping back in to low range
k 79 and rigsby seem to be proper Fuller drivers
