Here’s a couple of twinstick set-ups. One is the with two gear boxes, the other is a Eaton Fuller with the extra stick working the range change.

That’s the way to do it, but hang 75 tons on the back and the dynamics change quite considerably. I note he wasn’t using the clutch as I mentioned either. He had also changed the original Mack ball-shaped tops on the gear sticks for straight ones nicked, I suspect off Caterpillar dozers, just as we did on Bells over 40 years ago.
This bloke makes it look easy, like his one handed method.

I always had that style of knob on the range stick, certainly suited one handing better.
As for the B61 clutch, remember how dreadful that pedal was, just using it once to get moving was enough for me.
I reckon you’d have had pretty slow diff ratios in the Bell’s trucks?
Massive weight to pull for the horsepower of the day.
Very low diffs, Cargo. If you could get 41mph out of them empty, you were flying. I used two straight knobs on the sticks because with a bit of judicious use of the oxy torch, you could bend the sticks so that they were as close together as possible to make it easier to one-hand a few changes. In 1971 Bells bought some cab-over R700 Macks but still with the twin stick transmission. These were a sod to change because the gear sticks were much longer and there was no feel at all for which cog you were in. Later they bought some R700s with the V8 Jimmy in with a 13-speed Road Ranger. Bloody luxury mate, bloody luxury they were.

hi
I used to drive one of those half cab fodens in the mid sixties they had the foden two stroke engine and twelve speed gear box. they had two gear levers, the main lever was a four speed and there was another lever down by left side of the seat that had three positions, its been such a long time ago, but I think the side lever was high / low and overdrive
